On this site we only use the 'GPX XML' format (to enter an trail trace or to download the GPS trace file). This interface allows you to convert your GPS files from one format to another. Even with those faults, though, locr is still pretty good, especially at the price.Depending on the GPS model you are using, the file format may differ. If locr would accept GPX files, not have the occasional tagging glitch, and write the GPSVersionID tag properly, it would be pretty awesome. You can also select a set of photos, and create a KML file of thumbnails for display in Google Earth with the push of a button. Select a group of photos that have been geotagged, and click on the “Show photos on map” button, and their positions will be indicated on the Google Map. You can then move the marker manually after the initial tagging to fine-tune its position. You can also enter an address into a search box, and have that be automatically geocoded for you. On the plus side, manual photo geotagging is fairly painless – zoom in to the area in a Google Maps interface, select the photo, and click on the “Manual geotagging” button to tag it. This will re-write the GPSVersionID tag to one that Picasa recognizes, and Picasa will then pick up the geotagging information in those photos.Īddendum: Check this follow-up post for a GUI for EXIFTool. There’s a fix for this: download EXIFTool, a free command-line utility for EXIF tags, re-name the executable file to exiftool.exe, copy it to the directory with the photos in it, and from the command line execute the following command:Įxiftool -GPSVersionID=0.0.2.2 -overwrite_original *.jpg The problem apparently results from a problem that Picasa has reading the GPSVersionTag created by locr. 9/3/08: I’ve heard this is no longer an issue. The geographic location is written in the EXIF tag, but some programs (like Picasa) can’t read EXIF tags modified by locr. Sometimes, it won’t tag a photo in a series if that happens, click on the “Clear EXIF location tags”, and that may be enough to get it to work.ģ. Hopefully, locr will recognize the need to accept the standard GPX format in their program, and add it as an option sometime soon.Ģ. You’ll have to open the GPX file in a text editor, manually delete the trackpoints with no timestamp, then save the file as a new GPX file before using GPSBabel to convert it to the nmea format. In particular, if any of your GPX trackpoints don’t have a timestamp, GPSBabel won’t be able to create the nmea file, and will generate an error message. Make sure you have the latest version of GPSBabel and the GPSBabelGUI. The gpx file will be saved in the nmea format, which then can be opened in the GPS Photo software. In the “Filter” window activate the “GPS fixes” check box and select “pps” as option.In the menu click “Options” and select the “Filter” command (or click the “Filter” button).Do not forget the “.nmea” file extension! Click the “Start the file save dialog” button to determine the output folder.As “Output Format” select “NMEA 0183 sentences”.Click the “Start the file open dialog” button and select the respective folder and input file.In the GPSBabel window select the “Format” of the input file: “GPX XML”.Double-click the “GPSBabelGUI.exe” file to start GPSBabel.You can convert GPX to nmea using GPSBabel, and the following procedure from the help file: One of the biggest pains of locr is that it doesn’t accept standard GPX files for geotagging – it requires nmea files. The software does work, but it’s not without quirks, particularly for automatic geotagging with GPS data.ġ. You can either manually geotag a photo using a Google Maps interface, or use GPS data to assign geotags. Make sure you download the PDF manual as well, as you’ll probably need it. Geotagging can be done with separate software called “locr GPS Photo” the software is free, and available for download even without registering for the site. Basic accounts are free, and while I assume that premium accounts will be available for a price at some point, I can’t seem to find any mention of that on the site. Locr is a web album site oriented around geographic location, where you can upload geotagged photos, share them, and have them display in an album or on a map interface.
