Orthorectification

Orthorectification is the process of removing the distortion within an image caused by terrain relief and the camera. This is done by modeling the nature and magnitude of geometric distortions in the imagery. Camera or satellite models in conjunction with limited ground control, allow construction of correction formulae that produce accurate, geometrically correct, map-oriented imagery. SATPALDA uses Leica Photogrammetric Suite to produce Ortho images..…read more

Aerial Triangulation

Aerial Triangulation is the process of contiguous densifying and extending ground control through computational means. This operation includes establishing ground control points; performing interior orientation; measuring and transferring all tie, check, and control points appearing on all photographs manually; and performing a least squares block adjustment..…read more

Terrain Modeling

A digital terrain model is a topographic model of the bare earth i.e.terrain relief. The data files contain the spatial elevation data of the terrain in a digital format which usually presented as a rectangular grid. Vegetation, buildings and other man-made (artificial) features are removed digitally - leaving just the underlying terrain ( on the other hand, Digital Surface Model (DSM) is usually the main product produced from photogrammetry..…read more

Topographic Mapping

Topographic Maps are essential instruments for a variety of monitoring and planning activities. At SATPALDA Mapping projects in support of planning, engineering, and design are implemented and completed by our photogrammetric professionals. Various data sources are utilized in for generation of mapping products that include contour, planimetric and cultural CAD and GIS files, digital terrain models (DTMs) and other feature which are of interest to the customer. Our team has extensive knowledge of the application of advanced spectral processing to extract features and information for use in spatially-referenced business systems…..read more

Land Cover Mapping

Telecom Providers all over the world are depending on digital Land use (clutter) maps derived from high resolution geodata to improve radio network planning. These maps are used in all of today's state-of-the-art radio frequency (RF) propagation tools to model path loss, signal attenuation and frequency re-use. A system designed with accurate geodata will result in both lower costs for infrastructure and drive testing..…read more
