1. A system for three-dimensional feature extraction from imagery of a surface, comprising:
a vector extraction engine operating on a computing device;
wherein the vector extraction engine is configured to:
receive a stereoscopic raster image pair of the surface, the stereoscopic image pair comprising a first raster image and a second raster image;
identify one or more image features that are homologous between the first raster image and second raster image;
compute a vector difference between the first raster image and the second raster image for each of the identified one or more image features; and
construct a three-dimensional digital surface model of the surface based on the vector difference.
