1. A system for automated conversion of two-dimensional hydrology vector models into valid three-dimensional hydrology vector models, comprising: a vector extraction engine comprising a plurality of programming instructions stored in a memory and operating on a processor of a computing device, and configured to retrieve vectors from, and send vectors to, a vector storage such as a vector database; a DSM (digital surface model) server comprising a plurality of programming instructions stored in a memory and operating on a processor of a computing device, and configured to retrieve a DSM from a DSM storage, and further configured to compute a DSM from stereo disparity measurements of a stereo pair retrieved from a raster storage; a rendering engine comprising a plurality of programming instructions stored in a memory and operating on a processor of a computing device, and configured to receive a plurality of data from other components of the system and create visual representations in the form of three dimensional hydrology vector models of the data for review by a human user.
