    An accurate and appropriate GIS database depends on the geographic coordinate system (sometimes is used interchangeably with datum) your are using. For example, in the North America, commonly used datums are NAD37, NAD83, and WGS84. Throughout our package, we are using WGS84 datum because WGS84 is commonly used all over the world and it is the default geographic coordinate system for the Global Positioning System (GPS).

If your datum is not WGS84, please transform it to WGS84 datum before you using this package.
