In this paper, we present an overview of the georeferencing capabilities that enable registration of digital maps (raster data) with contours (vector data). This paper outlines the theory and standards used for proper geographic referencing of digital maps, and focuses on extraction of georeferencing information from TIFF and ESRI IMG raster file formats. Given 2D maps and 3D contours, georeferencing transformations are described for translating between spatial points specified in three different coordinate systems: latitude/longitude, UTM, and pixel.
We interpret and utilize georeferencing parameter information embedded in different types of digital maps to provide a system that can geo-register contours for several popular map types and their file formats.
