Abstract: Disclosed is a model and simulation (M&S) tool that allows users to manipulate the metadata of terrain and imagery files (geoTIFF files) to represent changes in the terrain or even add assets to them, such as buildings, geographic features (e.g., changed geography), or trees The disclosed M&S tool is able to add and/or remove features from the geoTIFF file by either directly manipulating the metadata of the file or by creating what is termed herein as a “shapefile” to overlay the changes on top of the file metadata. This manipulation enhances the fidelity of older geoTIFF datasets by selectively updating and/or adding content to the data and allows users to rapidly generate usable datasets within a physics based digital environment.
