Record my GPS position
|Author:||Grzegorz Adam Hankiewicz <email@example.com>|
Record my GPS position is a simple iPhone client to record and save GPS information. The stored positions in the database can later be extracted through iTunes file interface or emailed in CSV/GPX format to process for different purposes with external programs.
The CSV dumps contains all the possible device information while the GPX version is just for convenience allowing you to view positions in another program, since most information is stripped. The csv_to_kml/csv_to_kml.py script can convert the CSV file to a prettier KML/GPX file for opening in Google Earth.
Note that for the moment the program only uses active GPS, which drains the battery quickly, even when running in the background. Don't run it for more than an hour if you want to use your iPhone as something other than a dead weight.
The app works for the iPod touch, but the accuracy varies a lot and you depend on wifi location, so you won't get very useful readings in open fields, only in crowded cities which may have been previously mapped by Skyhook (http://www.skyhookwireless.com/), the people doing wifi core location for Apple. On the plus side I had my iPod touch on with the program running in the background for a whole day and didn't consume more than a quarter of the battery, so it seems the wifi location doesn't require as much power.
Record my GPS position can be downloaded for free from the Apple App Store (http://itunes.com/apps/electrichandssoftware/recordmygpsposition/). You can find other of my creations on the App Store under my Electric Hands Software brand (http://itunes.com/apps/electrichandssoftware/) which you can also find at http://elhaso.es/.
For requests and problems, feel free to use github's tracker at https://github.com/gradha/Record-my-position/issues.
The source code uses SDK 4.1 and deploys on 3.x. Patches are welcome to make it compile out of the box with previous SDK versions. In order to dynamically generate the versioned splash number, you need Cobra (http://cobra-language.com/) to compile the script/watermark.cobra program and run it.
Here are the steps to compile and build yourself everything:
Perform some terminal magic:
git clone git://github.com/gradha/Record-my-position.git cd Record-my-position git submodule init git submodule update
If you want to generate the versioned splash images:
cobra scripts/watermark.cobra -run-args vX.Y.Z
If you don't want to bother with cobra, simply copy the Default*.png images from resources/reference to resources so that XCode can find something.
Open Record_my_position.xcodeproj with XCode and build and run.
Turn on the GPS tracking and record some positions.
In the Share tab use the button that sends you the logs.
Process the CSV logs with csv_to_kml/csv_to_kml.py, a Python script. It generates KML or GPX files.
Open the converted KML/GPX files with Google Earth.
