Abstract

A system for enhanced geospatial modeling using a spectral data analytic cube classifier and normalized multispectral raster data, comprising a geospatial modeling server that receives and analyzes input imagery, a data import/export server that provides data for review or interaction and receives data to provide to the analysis server, and a database that stores data, and a method for enhanced geospatial modeling using raster data according to the system of the invention.

Claims

1. A system for enhanced geospatial modeling using a spectral data analytic cube classifier and normalized multispectral raster data, comprising:

a geospatial modeling server computer comprising at least a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, wherein the programming instructions, when operating on the processor, cause the processor to;

analyze and process input imagery, the processing comprising at least the operations of image normalization using atmospheric compensation through radiometric balancing, and feature extraction using a spectral data analytic cube classifier;

provide the normalized image data to other components of the system;

a database computer comprising at least a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, wherein the programming instructions, when operating on the processor, cause the processor to;

store data received from other components of the system and provide the data for future review as needed;

a data import/export server computer comprising at least a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, wherein the programming instructions, when operating on the processor, cause the processor to;
