Google Earth Package
The Geo-location, or geo-tagging is the ability to bind to any object, document, service (real or virtual), accurate information about the Earth through its positioning coordinates and any other additional data (eg. height above the ground) that you can easily organize, search, view graphically on digital maps.
To date there are various tools and services of electronic cartography that permit to use Geo-location for graphical representation of geographical information. Among these Google Earth is probably the best in terms of fluidity, detail and precision of three-dimensional navigation.
The “Geo-localized” contents of Shouf Biosphere Reserve package (images, text, photos, points, lines, polygons) made available in compressed KML (KMZ), designed specifically to manage three-dimensional geospatial data in the programs Google Earth, Google Maps, Google Mobile Maps and many other mapping programs.
GPX (the GPS Exchange Format) is a lightweight XML data format for the interchange of GPS data (waypoints, tracks and routes) between applications and Web services on the Internet.
GPX has been de-facto XML standard for lightweight interchange of GPS data since the initial GPX 1.0 release in 2002. GPX is being used by dozens of software programs and Web services for GPS data exchange, mapping and geocaching.
If you own a GPS receiver, find out how GPX is helping to make all your favourite applications work togheter:
GPX is a data format for exchanging GPS data between programs, and for sharing GPS data with other user. Unlike other data files, which can only be understood by the programs that created them, GPX files actually contain a description of what’s inside them, allowing anyone to create a program that can read data within.
An individual IMG file is a binary representation of raster map data used by Garmin GPS receivers and the MapSource map utility. It is a closed/proprietary format developed by Garmin.
The IMG format appears to be structured to optimize rendering speed of the GPS device first, and minimize file size second. This is consistent with the fact that GPS receivers generally have low-speed, low-power processors (compared to a personal computer) and therefore benefit from algorithms and data organizations that minimize the work needed to draw the display. The secondary concern, file size, stems from the limited memory present in most Garmin receivers compared to the sizes of the map files, themselves. The IMG file makes every effort possible to conserve bytes, something that is particularly evident in the section of the file that defines the “text labels” for map elements (streets, points of interest, etc.).
