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 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. This process ultimately provides exterior orientation parameters for photographs read more

Terrain Modeling (DTM)

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 read more

3D Modelling

SATPALDA has significant experience producing 3D city models at various levels of detail. These city models can be used in various applications such as navigation and location-based services.Accurate cartographic feature extraction, map updating, digital city models and 3D city models in urban areas are essential for many applications, such as military operations, disaster management, mapping 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 read more


Spaceborne imaging sensors provide global coverage of the planet surface on a routine basis. But the resolution of multispectral images may be inadequate for certain applications, especially those crucial for urban objects. A new generation of satellites, such as GeoEye-1, WorldvView-1 Ikonos, QuickBird, and SPOT-5, now offer high-resolution MS and panchromatic (pan) images.Certain data-fusion techniquestake read more

ScanEx Image Processor®

Satellite imagery is a source of vast geospatial information. These days we are witnessing more and more global problems being solved with the help of remote sensing data. Many people understand the potential of the new technology but are constrained either by pricing of the tools read more


LiDAR(Light Detection And Ranging) provides one of the most accurate and expedient ways to capture elevation data from ground. It is an optical remote sensing technology that can measure the distance to, or other properties of a target by illuminating the target with light, often using pulses from a laser. Typical horizontal accuracies range between. read more
