Raster to Vector Conversion for Maps

The Difference between Raster and Vector Maps

A raster map is basically an image that has been acquired by scanning a paper map with a large format scanner.  The resulting file is normally stored in a TIF format, and is comprised of individual pixels, with each individual pixel value creating the spatial location for a specific attribute, such as elevation, color, or some other identifying characteristic.

By comparison, vector maps are generally “drawn” maps with data that comes in the form of points and lines.  The points and lines are related geometrically and mathematically, with points stored using the x-y coordinates (for two-dimensional) or x-y-z coordinates, when height or depth is taken into account.
