BT747

Project to control GPS Dataloggers, mainly MTK based and convert GPS logs to several other formats using filters, etc. Runs on most platforms (Desktops, Linux, Mac, Palm, Mobile Phone, PocketPC).

GeoChat

Geochat emerged from a simple concept - can I send an SMS message and see it on a map? From there the concept has evolved, and geochat has become a project to build a collaboration platform for the lowest common denominator communication tools, considering as highest priorities the needs of ... [More] workers of humantiarian aid, international health and disaster response. The main drivers for the project are the feedback of the InSTEDD programs in South East Asia, excercises such as GoldenShadow?, and a growing community of humanitarian and health workers who spend their days in technologically austere environments. We invite anyone from any line of work to use and contribute user experience, technical, and any other kind of feedback. [Less]

googleearth-autohotkey

This is a collection of tools for working with Google Earth, reading/modifying coordinates, converting between different format coordinates, saving the current Google Earth position to JPEG files as Exif GPS data etc. ProgramsGoogle Earth PositionA tiny program for reading coordinates from the ... [More] Google Earth client (or editing coordinates to make Google Earth fly to a new location). The Copy buttons are intended to be useful for pasting coordinates and LookAt parameters into a spreadsheet, for example when generating KML using Google's Spreadsheet Mapper 2.0 Latest version: 1.12 Download: GoogleEarthPosition.exe Google Earth PhotoTagA small program for adding Exif GPS data to JPEG files and reading coordinates from the Google Earth client. With the Auto-Mode enabled any new file drag-and-dropped onto the PhotoTag window will automatically be tagged with the current coordinates from the Google Earth client. Latest version: 1.21 Download: GoogleEarthPhotoTag.exe The program requires the Exiv2.exe command line tool by Andreas Huggel which can be downloaded (for free) from http://www.exiv2.org/ The options to read/write Exif GPS data can be added to the windows right-click menu for JPEG files (click on the button in the About: dialog to add these options into the registry). The program can write KML output for showing a collection of photos inside Google Earth, like in this screenshot: To edit the style of the popup balloon edit the *.PlacemarkStyle files in the same directory as the executable. Any files with a .PlacemarkStyle extension will automatically show up on the Placemark style dropdown list in the PhotoTag program window. The program will include photo comments from descript.ion files or JPEG embedded comments in the placemark balloons. JPEG Comments or descriptions can also be edited in the PhotoTag GUI (configure which type to edit using the right-click menu; JPEG comments are stored inside the file itself so will stay with the file when you move/copy it, descript.ion comments are kept in a separate file and are faster to read/store, but not understood by all programs). LatLong ConversionA tiny program for converting coordinates between Degree Minute Second and Decimal formats. The tool can handle the following DMS formats: 8 deg 32' 54.73" South 119 deg 29' 28.98" East 8°32'54.73"S, 119°29'28.98"E 8:32:54S,119:29:28E Decimal coordinates are in the format: -8.548333, 119.491383 Latest version: 1.07 Download: LatLongConversion.exe SourceThese programs are written in the AutoHotkey language (http://www.autohotkey.com) The source code for the programs can be downloaded from the Google Code source tab. There is also a library file libGoogleEarth.ahk which includes the following functions: Converting Coordinates Deg2Dec() - convert from 8°32'54.73"S, 119°29'28.98"E into -8.548333, 119.491383 Dec2Deg() - vice versa Dec2Rel() - convert into 0/1 55/1 5617/100, 78/1 36/1 2061/10 format (useful for raw Exif GPS data) Google Earth functions IsGErunning() - simple check to see if the Google Earth client is running GetGEpos() - get the current Google Earth coordinates and LookAt camera info using the COM API GetGEpoint() - get the current Google Earth coordinates and altitude using the COM API SetGEpos() - fly the Google Earth client to a specific coordinate FlyToPhoto() - fly the Google Earth client to the coordinate stored in a JPG file GEtimePlay() - start playing timeslider animation (useful when recording movies as GE Pro hides time control) GEtimePause() - stop playing timeslider animation JPEG Exif, Exif GPS, XMP tag and JPEG Comment functions GetPhotoLatLong() - read the Exif GPS Latitude/Longitude stored in a JPG file GetPhotoLatLongAlt() - read the Exif GPS Latitude/Longitude/Altitude stored in a JPG file SetPhotoLatLong() - write Exif GPS Latitude/Longitude data to a JPG file SetPhotoLatLongAlt() - write Exif GPS Latitude/Longitude/Altitude data to a JPG file ErasePhotoLatLong() - delete the Exif GPS Latitude/Longitude/Altitude data from a JPG file GetExif() - read full Exif data from a JPG file !GetJPEGComment() - read JPEG embedded comment !SetJPEGComment() - write JPEG embedded comment SetXmpTag() - read JPEG file XMP tags GetXmpTag() - write JPEG file XMP tags Other ImageDim() - return image dimensions (uses ImageMagick identify.exe) FileDescription() - read file description from descript.ion file WriteFileDescription() - write file description to descript.ion file captureOutput() - capture output from console command line (uses cmdret.dll if available) The JPEG Exif functions require the Exiv2.exe command line tool by Andreas Huggel. It can be downloaded at http://www.exiv2.org/ (GPL 2+ license) The Google Earth COM API functions requires the Embedded Windows Scripting and COM for Autohotkey library (ws4ahk.ahk) from http://www.autohotkey.net/~easycom/ The JPEG Exif functions will optionally use cmdret.dll if present (removing the need for temp files while capturing command output) http://www.autohotkey.com/forum/topic3687.html (already bundled in GoogleEarthPhotoTag) Further information about the Google Earth COM API can be found here: http://earth.google.com/comapi/ These programs are distributed without any warranty. The functions for writing to JPEG files can probably be considered safe as they rely the Exiv2 command line tool for file write access (and all writes in the PhotoTag program are verified by a read operation afterwards). However, do make sure there is a backup of all files before using these programs. [Less]

jpegtokml

Use the location information found in the exif data to generate a kml file and thumbnail of the photo. Basically, it does the same thing as picasa putting the photos on google earth or google map without the need to upload your photos. This script is 'ad-hoc' and simple, feel free to improve it.
