Satellite imagery consists of images of Earth or other planets collected by satellites. Imaging satellites are operated by governments and businesses around the world.

GeoEye's GeoEye-1 satellite was launched September 6, 2008. The GeoEye-1 satellite has the high resolution imaging system and is able to collect images with a ground resolution of 0.41 meters (16 inches) in the panchromatic or black and white mode. It collects multispectral or color imagery at 1.65-meter resolution or about 64 inches.

DigitalGlobe's WorldView-2 satellite provides high resolution commercial satellite imagery with 0.46 m spatial resolution (panchromatic only). The 0.46 meters resolution of WorldView-2's panchromatic images allows the satellite to distinguish between objects on the ground that are at least 46 cm apart. Similarly DigitalGlobe's QuickBird satellite provides 0.6 meter resolution (at NADIR) panchromatic images.

DigitalGlobe's WorldView-3 satellite provides high resolution commercial satellite imagery with 0.31 m spatial resolution. It also carries a short wave infrared sensor and an atmospheric sensor.The 3 SPOT satellites in orbit (Spot 2, 4 and 5) provide images with a large choice of resolutions – from 2.5 m to 1 km. Spot Image also distributes multi resolution data from other optical satellites, in particular from Formosat-2 (Taiwan) and Kompsat-2 (South Korea) and from radar satellites (TerraSar-X, ERS, Envisat, Radarsat). Spot Image will also be the exclusive distributor of data from the forthcoming very-high resolution Pleiades satellites with a resolution of 0.50 meter or about 20 inches.

The Cartosat series of satellites are a type of earth observation satellites indigenously built by India. Up till now 5 Cartosat satellites have been launched by ISRO. The Cartosat series is a part of the Indian Remote Sensing Programme. They were specifically launched for Earth‟s resource management and monitoring. Indian Cartosat-2C is a much more capable satellite, having a resolution of 25 cm (10"). It uses 1.2 m optics with 60% of weight removal compared to Cartosat-2. Other features include the use of adaptive optics, acousto optical devices, in-orbit focusing using MEMs and large area-lightweight mirrors. The satellite was to be launched on board PSLV during 2014, but had been delayed and was finally launched on 22 June 2016. Potential uses include weather mapping, cartography, and strategic applications.

"Prashant Surveys" has the knowledge and expertise to procure, process and provide solution or generate accurate base maps using any of the High resolution satellite images as per the requirements of the project. We have already procured and used "Digital Globe" and "Indian Cartosat" High resolution satellite images from NRSC, Hyderabad (a nodal Government body under ISRO in India) for many of our Government projects in India.

After carrying out the Ortho rectification of the above High resolution satellite images using the precise Ground Control Points, we can prepare an fairly accurate base map with customized GIS solution which can be readily used by small to medium sized municipal councils in India.
