1. A system for automated conversion of two-dimensional hydrology vector models into valid three-dimensional hydrology vector models, comprising: a computing device comprising a processor, a memory, and a plurality of programming instructions stored in the memory and operable on the processor, wherein the plurality of programming instructions, when operating on the processor, cause the processor to execute: a hydrology vector server configured to retrieve vectors from, and send vectors to, a vector storage such as a vector database; a digital surface model server configured to compute a digital surface model from stereo disparity measurements of a stereo image pair retrieved from a raster storage; a rendering engine configured to generate a visual representation in the form of three-dimensional hydrology vector model by projecting a two-dimensional hydrology vector model onto the digital surface model.
