- Activity Workshop writes to say that his multi-platform GPS track management and photo geotagging application Prune has been updated (see earlier Prune posts here and here). New features include:
- New map window in the View menu, showing points overlaid on OpenStreetMap images
- New function to launch a browser showing the area in either Google Maps or OpenStreetMap
- Handling of track segments, including loading, saving and exporting, and preservation during edit and undo
- New function to merge track segments for the current selection, to make one single segment
- Display of current and average speed on details panel
- Status bar showing confirmation of actions
- Much improved French texts thanks to generous user input
Written in Java, and runs on Windows, Mac and Linux
- Need to geotag a photo, but don’t have an application like Prune, GeoSetter or GPicSync handy? You can do it online using the Sunday Morning Rides GeoTag utility. Specify the location in a Google Maps interface, set the coordinates, upload the image (JPG only), and a minute or so later you’ll see the geotagged image (or part of it) on the web page. Then right-click on the image and save it to your computer. Even though you may only see part of the image on-screen, it does tag and save the entire image, apparently losslessly. Sunday Morning Rides also has an online GPX track builder and waypoint utility.
In the comments to my post on GeoSetter, someone suggested I take a look at GPSed Photo Take’n'Pin as an option for geotagging photos. GPSed itself is a service for uploading and sharing GPS track and point data. From the website’s FAQ:
GPSed, a location-based and geotagging service, is designed to enable real-time tracking from mobile devices and collecting track data in an online archive.
The service is designated for hikers, bikers, drivers, tourists, adventure travelers, sportsmen, photographers and GPS/GIS professionals working in various industries such as forestry, fishery, transportation and others. GPSed can also be used just for having fun.
GPSed Photo Take’n'Pin is their free application designed to use GPS track data to geotag photos. Gave it a spin, and wasn’t terribly impressed:
- You apparently can’t use a local GPX track file on your computer to geotag the photos, only one that you’ve already upload to the GPSed website. Since you likely already have that track on your computer, there’s no reason not to use a better geotagging program that supports local GPX files like GeoSetter. By way of contrast, the similar service locr provides a free application that does let you use your own GPS data to geotag your photos.
- I say “apparently” above because I couldn’t get the program to geotag my standard test photoset even with an online track, and there’s no help file in either the program or the website to help me sort out what the problem might be.
- Even if I could successfully geotag a photo with the GPSed Take’n'Pin application, there’s nothing I can do with it on the GPSed website. You can take the photos and export them to Google Earth, Picasa, or Flickr, but you don’t need this program to do that. With locr, you can upload the photo to the website and share it and its location with others.
- The program crashed on me several times (I’ll cut it some slack on that, since it’s labeled as a beta).
Given those issues, I’ll stick with my previous statement that GeoSetter is the best geotagging application I’ve seen to date, with GPicSync a worthy alternative. Even if GPSed Photo Take’n'Pin worked as advertised, it doesn’t offer any features to make it worthwhile.

Garmin handheld GPS units use vector graphics to display imagery, so it’s generally been considered impossible to view raster imagery on them, like USGS topo maps or aerial photographs. But I’ve figured out a way, and created a program that lets you convert free USGS topo maps downloaded from the Seamless Server, black-and-white DOQQs, color satellite imagery, any georeferenced raster imagery, to a Garmin-compatible format: Moagu - the Mother Of All GPS Utilities. Rich Owings has the first review at GPS Tracklog (he likes it!).
Here’s a few screenshots from my Garmin 60Cx:

POILoader: A long and involved post of mine from a few weeks back described methods for managing multiple custom POI files on a Garmin GPS, to get around the limitation that POILoader erased the current POI set when uploading a new one. The process was mildly painful, involving going into the GPS’s memory, then copying and renaming the *.gpi POI files to prevent them from being erased; I refer you to that post for the gory details. The latest version of the POILoader makes this process a lot simpler: you now have the option of saving the *.gpi files directly on your computer, where you can rename and manage them directly before copying them into the /Garmin/POI directory on your GPS unit. A lot easier.
Curiously, there’s one additional option in the program, which lets you install the POIs into Garmin’s MapSource program under a specific name. It’s curious because there’s no current support in MapSource for POI uploading; I’d look for that capability in an upcoming release.
DNRGarmin: In comments on this post, Thomas notes that the bug that kept USB connectivity in DNRGarmin non-functional unless you installed with administrator rights has been fixed; it now works with any installation. If you have a Garmin handheld GPS, the latest version of DNRGarmin is a must. You can upload data from GPX, Google Earth’s KML format, text, DBF and shapefile to your Garmin using this program, and conversely save data from your GPS in these formats; it can even re-project data in UTM, Lambert, etc. to geographic coordinates for. Even if you don’t have a Garmin, it’s a handy program to have for converting from one format to another.

Last week, I posted on how to convert a point shapefile to a Garmin custom POI file, and how with some manipulation you could include a fair number of the shapefile attributes in that POI’s data screen. But with only 6 lines of dataspace available, and only about 20 or so characters per line, you can only fit so much data onto a single data screen before you run out of space. And there may be times when you need to fit in more data.
The solution is pretty straightforward - just create another set of data for the same set of POIs, and give this new dataset a different name. It’s easy to access this new dataset using standard POI database management; you can make it even easier to distinguish between different datasets by modifying the point name slightly, appending a letter or number to every POI name in the new dataset, distinguishing it from other datasets with the same name. Using this technique, and using a Garmin that takes external data cards, there’s virtually no limit to the amount of attribute data you can include for every point in a shapefile.

Garmin POIs (Points of Interest) datafiles can contain up to two lines of text data for the name, and up to four lines of data for the description, far more than the more limited space for the same data in a GPS waypoint. This gives you enough room to include at least some of a point shapefile’s tabular attribute data for a location, and take it into the field with you for reference. And while there’s typically a limit of 500 to 1000 waypoints on many Garmin GPS units, you can put tens of thousands of locations into a POI file, along with that associated data. Here’s one way to create Garmin POI files from a point shapefile, though you could use comparable tabular data as well.

Creating custom icons for Garmin POI files is similar to, but actually easier than, creating them for custom waypoints. I’ve covered the basic details of creating custom waypoint icons in two previous posts (part one and part two), and refer you to those for the general process. But the graphic format requirements are somewhat relaxed for custom POI icons compared to custom waypoint icons:
