Abstract

A method for editing composite geographical images, including importing a raster geographical map file, the raster file including geographical information identifying raster image data, global positioning reference data and a first projection that transforms geographical coordinates to linear coordinates, importing a vector geographical map file, the vector file including geographical information identifying vector objects, rendering a two-dimensional raster image including transforming linear coordinates to geographical coordinates according to the inverse of a prescribed second projection that transforms geographical coordinates to linear coordinates, and re-projecting the geographical coordinates to linear coordinates according to the first projection, rendering a two-dimensional vector image including projecting the vector objects according to the prescribed second projection, compositing the two-dimensional image raster image and the two-dimensional vector image as layers of a composite image, and editing the composite image. A system and a computer readable storage medium are also described and claimed.
