how to extract software from satellite receiver

Use this math model in the following situations: They can be applied to any image dataset. Rational Function (Extract from image) and Rational Function (Compute from GCPs) – Simple math models that builds correlations between pixels and ground locations. Suitable for use with any optical satellite data, regardless of resolution, such as CARTOSAT, LANDSAT, or SPOT. Toutin’s Model – A rigorous model that compensates for known distortions to calculate position and orientation of the sensor at time of image acquisition. More information on each of the steps that are run in this tutorial is included in the online Help Documentation for CATALYST Professional. This workflow can be used for DEM extraction from any supported stereo optical satellite data.

As conversion from a DSM to a DTM through manual editing can be a very time-consuming process, CATALYST Professional has automated the DSM to DTM conversion. DTMs only include the elevation of ‘bare earth’ with vegetation, buildings and other man-made features removed (though roads and bridges are typically retained). Many applications, however, such as orthorectification workflows, require a DTM as the preferred product. A DSM represents the earth’s surface and includes all objects on it, e.g., buildings, trees, etc. The following is a step-by-step tutorial of the procedure for extracting a digital surface model (DSM) (also referred to as a digital elevation model, or DEM) from stereo imagery and converting it to a digital terrain model (DTM).
