Feature Extraction

Feature Extraction from most of the commercially available satellite data products, including IKONOS, QuickBird, SPOT, ASTER, IRS, Landsat, Radarsat, MODIS, and NOAA. With our remote sensing capabilities we can provide services like Land use/land cover morphology data, Vector updates, High-resolution urban mapping, Forest density mapping and DEM extraction from stereo pair of medium resolution images. We can also extract/place the POIs (point of interest) for tourist maps with various sources.

When the input data to an algorithm is too large to be processed and it is suspected to be notoriously redundant (much data, but not much information) then the input data will be transformed into a reduced representation set of features (also named features vector). Transforming the input data into the set of features is called features extraction. If the features extracted are carefully chosen it is expected that the features set will extract the relevant information from the input data in order to perform the desired task using this reduced representation instead of the full size input.

Digitizing features is one of the most time consuming and tiresome aspect of creating or updating GIS data, but nevertheless it is very essential to the process of acquiring valid GIS data.
