Abstract

A system for automated conversion of two-dimensional hydrology vector models into valid three-dimensional hydrology vector models, comprising a vector extraction engine that retrieves vectors from, and sends vectors to, a vector storage, a DSM server that retrieves a DSM from a DSM storage and computes a DSM from stereo disparity measurements of a stereo pair retrieved from a raster storage, and a rendering engine that provides visual representations of images for review by a human user, and a method for automated hydrology vector model development utilizing the system of the invention.

First claim

What is claimed is:

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.

2. The system of claim 1 , further comprising a database computer comprising program code stored in a memory and adapted to store and provide information for other components of the system.

3. The system of claim 1 , further comprising a viewer device adapted to receive information from other components of the system and present the information for review by a human user.

4. The system of claim 1 , further comprising a plurality of input devices adapted to receive input from a human user and provide the results of the input to other components of the system.

5. A method for automated hydrology model development, comprising the steps of:
receiving, at a hydrology vector server, a plurality of input images;
extracting a plurality of hydrology vectors from at least a portion of the plurality of input images;
algorithmically cleaning at least a portion of the hydrology vectors;
enforcing vector attributes based at least in part on at least a portion of the hydrology vectors; and
computing a hydrology graph model based at least in part on at least a portion of the vector attributes.

6. The method of claim 5 , further comprising the step of cleaning at least a portion of the plurality of hydrology vectors.

7. The method of claim 6 , wherein the cleaning is performed automatically by the hydrology vector server.

8. The method of claim 6 , wherein the cleaning is performed manually by a human user.

9. The method of claim 5 , further comprising the step of designating at least a portion of the hydrology vectors for use as feature vectors.

10. The method of claim 9 , wherein the designating is performed automatically by the hydrology vector server.

11. The method of claim 9 , wherein the designating is performed manually by a human user.

12. The method of claim 5 , further comprising the step of automatically enforcing vector monotonicity based at least in part on at least a portion of the vector attributes.

13. The method of claim 12 , wherein the hydrology vector graph model is based at least in part on at least a portion of the vector monotonicity.

14. The method of claim 5 , further comprising the step of providing the hydrology vector graph model as output.

15. The method of claim 14 , wherein the output is stored, in a database, for future reference.

16. The method of claim 14 , wherein the output is displayed on a display device for review or interaction by a human user.
