Geocaching Software and Paperless Caching

GeocachingIn this, the latest in our best of the (discussion) boards series, we take a look at geocaching utilities. Before we get started, here’s the place to go if you haven’t heard of geocaching.

While my book, GPS Mapping, covers a wide range of mapping software, I did not get around to reviewing geocaching utilities in it. I was pleased last week to see this post on geocaching software show up on the official geocaching discussion board. Sputnik 57, a geocacher from Texas, was kind enough to pull this list together, giving a little bit of space to each manufacturer’s blurb, and a link to their product:

  • Geocaching Swiss Army Knife (GSAK) is the all in one Geocaching and waypoint management tool. Major features include: Multiple databases, sending/receiving waypoints to GPSr, conversion to many mapping formats, HTML output, extensive searching, macro support, backup and restore, distance/direction from other waypoints (including caches, locations, post codes) and much more.
  • CacheMate™ is a database for tracking GPS cache hunts. You can store information about caches or benchmarks, decode hints, and transfer data between CacheMate and the MemoPad application. Registered users can import LOC and GPX formatted XML files, which are available from Geocaching.com.
  • Watcher is a program that lets you view GPX files obtained from Pocket Queries (a membership benefit for Geocaching.com members). Offline viewing. filtering, and sorting are all possible, as well as merging multiple GPX files and outputting custom GPX files. Watcher is a GPX utility available at no charge (although tips are always appreciated) to paying members of Geocaching.com. It is our way of saying “thank you” to all those who support the site from which we have found countless hours of enjoyment.
  • Plucker is an offline Web and e-book viewer for PalmOS® based handheld devices and PDAs. Plucker comes with Unix, Linux Windows and Mac OSX tools, scripts, and conduits that let you decide exactly what part of the World Wide Web you’d like to download onto your PDA (as long as they’re in standard HTML or text format). These web pages are then processed, compressed, and transferred to the PDA for viewing by the Plucker viewer.
  • GPX Spinner puts a spin on your GPX files. Features include: Output a set of HTML files suitable for sending to a handheld device using Plucker or iSilo; Change the waypoint name to include the cache name, ID, difficulty, terrain, or any combination; Change the waypoint description to include the cache name, who it was placed by, difficulty, terrain, or any combination;Change the symbol to represent the type of cache (e.g. a camera for Virtuals, a penny for Micros, or a picnic table for Event Caches). Even change the default ‘Geocache’ treasure chest for regular caches; Change the symbol (e.g. to an animal) if the cache contains any travel bugs; Change the symbol (e.g. to a tombstone) if there are several recent Not Found logs; Fully configurable!
  • EasyGPS is the fast and easy way to create, edit, and transfer waypoints and routes between your computer and your Garmin, Magellan, or Lowrance GPS. Using EasyGPS, you can manage all of your waypoints and routes, and display them in lists sorted by name, elevation, or distance. EasyGPS connects your GPS to the best mapping and information sites on the Internet, giving you one-click access to street and topo maps, aerial photos, weather forecasts, and nearby attractions. And because EasyGPS is part of the TopoGrafix family of outdoor products, you’ll be able to exchange GPS data with EasyGPS and ExpertGPS users all over the world!

I should add that the focus here is on software for paperless geocaching, relying instead upon a Palm or Pocket PC device. Also, as long as EasyGPS was mentioned, I want to let you know that there is a full chapter on it in GPS Mapping, since it is such a great (and free) waypoint management tool.

Garmin US TOPO 24K Review

24kcomparison_2

UPDATE: This product has been discontinued. Read my review of Garmin’s new nationwide Topo US 24K maps.

One of the frustrating things about backcountry use of GPS is having to live with "as the crow flies" routing. That’s not so bad when you’re off-trail, but on trail, I’d prefer my GPS tell me that its five trail miles to the destination rather than three "as the crow flies" miles. The crow can fly, but I can’t.

On one of my last outings, I had a chance to try out Garmin’s US TOPO 24K which shows contour intervals closer to USGS 1:24,000 scale maps than their USA TOPO (1:100K) product, hence the name. During one outing, I happened to be on the dividing line between these two coverages, as captured in the screen shot to the left.

Clearly, this enhanced level of detail is desirable, but having routable trails excites me just as much. I couldn’t trick my GPS into capturing a screen shot of a route, Us_topo_24k_route_1but the image to the right  comes from the MapSource desktop. You can see that the software routed along the highway and a trail, but that it had to do "line of sight" routing where one trail was not on the map. It was really nice to know just how far I had to go to the next junction.

The formal name of this product is US TOPO 24K – National Parks, and you can purchase it for the eastern, central or western U.S. But as I discovered on this trip, it covers more than just national parks. The images shown here were not captured in national parks, but in the San Bernardino National Forest.

Creating Custom Maps for Lowrance GPS Receivers

In another of our continuing series of the best of the boards, this jewel comes to us from Groundspeak, the geocaching message board. In a Lowrance vs. Garmin response, I said…

…if you want to create your own maps, you can do this with the 60CS. With the H20, you can only add tracks. Lots of them, granted, but it is still a significant limitation, especially if you want to add contours.

To which Hoary, a geocacher from Massachusetts said…

There is a significant progress in regards of building your own maps for Lowrance iFinder. More details in Yahoo! MapCreate Format Group:

http://groups.yahoo.com/group/mapcreate_format/

Sure enough, information is posted there on a new tool, MP2LCM. I covered how to obtain data and create MP files in my book, GPS Mapping – Make Your Own Maps, but the ability to transfer those custom maps to current Lowrance units is a new development. Now I haven’t tried this yet, so if you have, chime in and let us hear your thoughts. Congratulations to the MapCreate Format group for all their efforts.

Downloading GPS tracks from MotionBased.com for trip planning

As promised in last week’s review of MotionBased software, I’m going to show you how to use their site to download tracks for trip planning. Recently, I was trying to find a good map for Annadel State Park, a little slice of mountain biking heaven in Santa Rosa, California. My wife and I used to ride there all the time before we were married, when she lived within a stone’s throw of the park. About the time I lured her away, there was a massive reconfiguration of the trail system.
An opportunity came up to ride Annadel again recently, and I really wanted a detailed map so I could plan to ride as much single-track as possible. I turned to MotionBased and searched their extensive trail network for MotionBased users who had mountain biked Annadel, which turned up nearly a dozen tracks.

I was able to download .gpx files for each one. This feature is a bit hidden, so let’s look at how to go about it. Go to MotionBased.com and click the Trail Network tab. Use the Quick and Advanced Filters to narrow your search. In my case I chose Cycling (Mountain Biking), MotionbasedRecreation for event type and California for location. I then narrowed the location to Santa Rosa using the advanced filters. This brought up 11 records for Annadel, which I selected using the check boxes. The next step is to click on the left side of the screen to select Map View instead of Table View. Your screen should now look something like the thumbnail to the right. 

As you can see, there is a Google Map image on the left and a list of selected tracks on the right. Click the Info link next to one of the tracks and a balloon will appear on the map, providing an option to export as a Google Earth (.kml) or .gpx file. I downloaded the 11 tracks as .gpx files.

Topofusion_7There are other ways to do this, but I chose to open the saved .gpx files in TopoFusion and used its Cut Track feature to remove stray track segments. The result is shown in the screenshot to the left. I then transferred the tracks to my GPS.

I was getting close to my goal, but I also wanted a good quality printed map.  As much as I like TopoFusion, it and other TerraServer based programs have very limited printing capabilities, and TerraServer topo maps are fairly low-resolution scans. So I transferred Annadel_mapthe tracks to National Geographic TOPO!, and printed the map shown to the right.

The folks at MotionBased have plans to incorporate waypoint management, so in the future you may be able to download those too. For the time being though, it’s a great resource for grabbing tracks placed online by other outdoor adventurers.


Making custom (not counterfeit) maps for your GPS

There was a story last week about counterfeit GPS maps causing drivers to get lost in Shanghai, which was widely reported in mapping blogs (like GeoCarta and The Map Room) and discussion groups.  But what do they mean by counterfeit maps? Jesse at Very Spatial started to address this, saying "I disagree with their use of the word ‘fake’, inaccurate is more realistic."  You can make custom maps for your GPS that may be sloppy or deceptive, or they may be more accurate than what you can buy commercially.

Let’s take a look at how this is done. What follows is a brief overview of a subject covered in great detail in my book, GPS Mapping – Make Your Own Maps, which includes step-by-step instructions.

Why would you want to do this? Well, you might be traveling to a foreign country for which there are no good GPS maps. Or you might just want better topo maps than what is available commercially. This is a common problem for outdoor recreation enthusiasts, as almost all GPS maps are based on 1:100K scale data, the one exception being Garmin’s US Topo 24K series (Amazon), which only covers national parks. Garmin’s US wide product (Amazon) shows contour lines 130 feet apart. I don’t know about you, but I like to know if I’m about to ride my mountain bike off a 100′ cliff! And while the Magellan (Amazon) and Lowrance products show contour lines much closer together, they actually interpolate the 1:100K data to do so, which is misleading to say the least.

On to how to make custom GPS maps…

Trip Report: Using GPS biking Mt. Diablo

This post launches a new category at GPS Tracklog — Trip Reports. The point isn’t to provide a trail guide, but rather to exhibit some of the ways to utilize your GPS. This report focuses on a circumnavigation of Mt. Diablo, a 3849′ peak that dominates the eastern side of the San Francisco Bay region.

My wife and I were in the area this past week doing GPS mapping demos, promoting my book, GPS Mapping – Make Your Own Maps. Since our days were open, we decided to get in a mid-week bike ride.  Living on California’s heat-deprived North Coast, we opted for a ride slightly inland. Mt. Diablo was our target, and since I didn’t know the area very well, I turned to a message board on mtbr.com for help. I wasn’t disappointed. Several people, especially EBrider helped out, designing an awesome loop that incorporated technical single track, loose and steep fire roads, and nearly 2,000′ of elevation gain.

EB sent me a track in the form of a .tpo file, which is a National Geographic TOPO! (Amazon link) file format. This, combined with the trail descriptions provided by EB and others at mtbr.com, gave me almost enough info to plan the trip, though I will admit to picking up a hard copy of a trail map so that I had good access to trail names and other features. Too bad the Mount Diablo Interpretive Association doesn’t have this map posted online. Online trail maps (often PDFs), combined with mapping software and aerial photos, are typically adequate for my purposes.

I took the track that EB sent and exported it from TOPO via my GPS (a real pain since TOPO makes you convert tracks to routes in order to export them). I then imported it into TopoFusion, which allowed me to see the track on a color aerial photo. USGS posts color urban aerial imagery for major US metropolitan regions online at TerraServer, with more locations being added on a frequent basis. These images are readily available in programs like TopoFusion and USAPhotoMaps, which add a better user interface and allow you to transfer data to and from your GPS. The color imagery extends into natural areas in many cases, and the detail is amazing, going down to 0.25 meters per pixel. Notice the waypoint (MDNPEAKTR) in the image at the right. Mt_diablo_2 You can see a fire road going off to the north from the waypoint and, while the online image isn’t as sharp as the original, you can actually make out single-track going off to the northeast!  The single-track leaves the image near the top of the right-side.

With TopoFusion, I traced the single-track as accurately as possible, and created waypoints for major trail junctions. I then loaded the waypoints and redrawn track to my GPS, making the track blue so that I could clearly distinguish it from the tracklog being created as I rode.
The only things left were to create a route to guide me from waypoint to waypoint, and generate a printed map. I’ve posted the ride at 4 meters per pixel (black & white) using TopoFusion’s PhotoFusion feature, which apparently doesn’t yet allow access to the color aerial imagery when using their HTML Image Map feature.

EDIT: I asked at the TopoFusion message board and found out that you can capture a color aerial .jpg and replace the one generated by TopoFusion. My Mt. Diablo PhotoFusion page now shows the color aerial at 4 meters/pixel..

If you want to to learn more about how to use GPS and mapping software, check out my book. It has chapters on National Geographic TOPO!, USA PhotoMaps and TopoFusion. And for those of you who want to know more about the ride itself, read on…

Interview: DeLorme introduces handheld GPS

Continuing our series of interviews with mapping software companies, we turn today to DeLorme’s Caleb Mason, for the scoop on some exciting new proucts. Pay particular attention to the answer to the first question, for it holds two major announcements — not only is DeLorme introducing a handheld GPS, it will also accept raster imagery!

Caleb, can you tell us about any new products or features that you are working on, and when we might see them available?

DeLorme announced at this year’s Consumer Electronics Show our first-ever handheld GPS receiver, the Earthmate GPS PN-20. This device will sell for around $200 and include a color screen for displaying DeLorme vector maps as well as raster imagery.

For years we have heard from customers that what they really want to do is load our vector color topographic maps on a handheld GPS receiver. This has not been possible as the major GPS suppliers use closed systems designed to sell their own mapping software. Now, customers will have an affordable, high-quality solution for use with our maps and software to make the outdoor experience that much better. More competition and choices within the GPS market will help expand awareness and sales for all providers.

Many of the most popular features of DeLorme software will be carried over to the new GPS. For instance, it will be possible to create automatic trail or road routes on the desktop software and transfer these to the GPS. This automatic route generation feature is very powerful and limits the time it takes to hand-draw routing information. Waypoints and Draw objects will be easily transferred between the desktop software, the GPS, and back to the desktop.

A new version of DeLorme Topo USA is planned for release in conjunction with the Earthmate GPS PN-20, tentatively scheduled for the first half of 2006. The software will work seamlessly with the new GPS and also contain a new 3-D mapping engine that will be far superior to the current one.  Updated trails and BLM data are planned along with much more.

Flying with GPS on commercial airliners

Air_nc
Well, I finally did it. I pulled out my GPS on an airline flight to record the track. Just what brought about this happy event, and why hadn’t I done it before? First of all, you have to be flying on an airline progressive enough to allow the use of GPS devices.  The excellent, all things GPS website, GPSinformation.net maintains a list of airlines that allow / disallow use. It seems that many of them haven’t figured out that these devices, with notable exceptions, aren’t capable of transmitting anything, only receiving. And before you get too excited about your next flight, note the line that says “This actually means pilot discretion in all cases.”  I was flying Southwest, which clearly states in its in-flight magazine that GPS receivers are allowed once you reach cruising altitude (10,000 feet). UPDATE: Southwest no longer allows use of GPS while in flight.

In the past, I found myself flying airlines with draconian, Luddite-inspired policies, but not this time. With flights so crowded these days, I often opt for an aisle seat too. You would think that someone who enjoys canyoneering wouldn’t be bothered by confining spaces. I guess some of us react differently to wilderness than we do to being cooped up in a flying box with a few hundred strangers. This time though, my wife was with me, and the first leg of the flight wasn’t full, so we grabbed an entire row and I settled into the window seat. We were flying from Raleigh-Durham, NC (RDU) to Oakland, CA (OAK), returning from a NC tour promoting my book, GPS Mapping – Make Your Own Maps. I alternately held the GPS up to the window or set it on the tray to record the flight. There was a stop in Nashville, and the flight was going to be full from that point on, so we switched to a two-seat exit row. There was no window seat, but I found that I could stick my GPS, a Garmin GPSMap 60CS, in the seat back pocket (of the row in front of me) next to the window. That worked pretty well, though I did get some loss of coverage at times. I had my GPS connected to my laptop, which was running National Geographic TOPO! The clickable image at right above is the first half of the journey, superimposed on a map from TOPO! See that dogleg flying into Nashville? Man, I sure felt that turn! 

Air_utah
The next image shows is the second half of the flight. I was busy working on my laptop, so I wasn’t paying a lot of attention, but did manage to spot some favorite haunts in Utah — Moab, Wall Street (a climbing Mecca), Canyonlands, and the San Rafael Reef.

I’ve heard some people suggest using a Gilsson external antenna with suction cup mount attached to the aircraft window as a way to save your arm and get better reception. That sounds great, but they have more chutzpah than me. In this post 9/11 world, you can just imagine the reaction of fellow passengers and the cabin crew!

Interview with Fugawi’s Robin Martel

In my book, GPS Mapping – Make Your Own Maps, I included a chapter on Fugawi GPS Mapping software, a program that allows you to use maps downloaded from a variety of sources. While at Outdoor Retailer recently, I was fortunate to be able to spend some time speaking with Fugawi’s Robin Martel of about the future of mapping software and GPS. Robin was kind enough to agree to an interview, and here it is…

Robin, can you tell us about any new products or features that you are working on, and when we might see them available?

We are always working on new product or new features. The claim to fame of Fugawi is its support for a very wide variety of third party map formats. Currently we are working on adding support for yet more formats, including several vector formats. We are also working on a variety of niche market map-based products, which capitalize on our tried, and true map engine.

Do you anticipate offering aerial photos at any point in the future?

We currently offer complete aerial photography of England and Wales (Fugwai SkyView UK). This photography is seamless and can be viewed in standard ortho ‘map mode’ or viewed in stunning 3D.

 

Fugawi Global Navigator, supports USGS air photo images. Because Fugawi Global Navigator (USA Edition) is supplied with complete elevation data of the USA, any of these images can also be viewed in 3D.

What are the primary limitations inhibiting development of mapping software?

Mapping software can be made to do almost anything. Generally speaking, the most difficult aspect of producing mapping software products is licensing. Most map data (with the exception of some US government data) is copyright by the data owner and can only be reproduced with permission, or under a commercial license agreement. This becomes very difficult when other governments or commercial interests, who are not involved in consumer applications, own the data.

 

What improvements would you like to see in GPS receivers?

 

The GPS manufacturers are doing an excellent job with innovation. While GPS receiver design continues to evolve and improve, most of the development now is in better and faster on-board operating systems with greater processing power and memory. This is not related to the GPS receiver but rather to the device in which the receiver is embedded. We would like to see growth in more ‘outdoor suitable’ hand held computer devices with embedded GPS. This is happening now and is evident in a variety of PDA devices, but there is still a way to go to produce the ideal GPS enabled handheld computer platform for outdoor use. As these hardware platforms proliferate, with standard on-board operating systems such as Pocket PC, Palm, Linux, etc., we should see a new growth in mapping applications designed for use on these systems.

 

What is way out there, years in the future, for your company or for the entire industry? What  would your ideal GPS unit of the future look like?

 

The ‘GPS’ component of the GPS enabled device is becoming insignificant. More devices, with faster processors, more on board memory and better data storage, and better suitability for use outdoors will lead to a new generation of mapping and location based services.

 

 


Topo overlays for Google Earth

Following a sideband comment, I had resolved to review the differences between Google Earth and MSN Virtual Earth.  I misread the email though. It wasn’t saying that Virtual Earth shows topos, merely that it will show both road maps and aerial photos, something Google Earth and Google Maps already manage to do quite well.

I thought it was worth a comparison of the programs though, but in researching the topic I stumbled across people using topo maps in Google Earth.  A search for "contour" and/or "topo" on the Google Earth Community message board should turn up some examples. Find a likely looking message and then click "Open this Placement" in the messsage header. You’ll have to have Google Earth installed to see the results of course.

Unfortunately, I have no time right now to check out how this is done. Maybe a reader already knows and will share?…
