Orthorectification

Most types of raw satellite imagery require geometric correction to remove terrain distortions. We utilize the 30 m Aster GDEM for the most of the orthorectification work.

Mosaicking

Due to seasonal variations and the illumination conditions, different sets of satellite images may look different. We offer professional mosaicking services to produce seamless and color balanced image mosaics.

Pan-sharpening
Powered by FuzeGo™

Pansharpening is a process of merging high-resolution panchromatic and lower resolution multispectral imagery to create a single high-resolution color image.

Atmospheric Correction

Need spectral reflectance data? We provide robusted DN to Reflectance Conversion Service which removes atmospheric effects from your satellite image.

More on the satellites

In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit.

Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon.

Corona
America's First Satellite Program

Corona, USA's first operational intelligence satellite, carried sophisticated optical cameras (KH-4B system) to acquire imagery of the Earth from space at an altitude of 80 nautical miles (150 km). It was launched in 1967. The mission life of the system was 19 days. The best quality resolution of 6 feets (2-metre) can be enlarged nearly 40 times up to 1:7,500 from the original film at a nominal scale of 1:247,500.

Declassified in 1994, the photos taken by the satellite constitute a valuable source of historical information for study of environmental changes.

Landsat program
The world's longest continuously acquired collection of land remote sensing data.

Landsat was called ERTS (Earth Resources Technology Satellites) when it was first launched in 1972. This series of satellites was renamed Landsat in 1995. Administered by USGS/NASA, Lansat-5 acquired only colour images of 30-metre resolution. Landsat-7, which launched on April 15, 1999, is orbiting the Earth at an altitude of 705 km. It acquires black and white images with a resolution of 15-metre and colour images with a resolution of 30-metre.

Unlike the Corona satellite which captured imagery on photographic films, Landsat satellites carry sensors to collect electromagnetic radiation reflected from the ground. The data ware is converted into electrical signals and then transmitted in digital form to a ground receiving station. These digital data are subsequently processed to generate images.

The imagery is composed of a matrix of pixels. Each pixel represents the amount of light within a spectral band reflected from the Earth’s surface. Using various combinations of spectral bands, different techniques of image processing and enhancement as well as merging of different remotely sensed data, spectacular images can be generated to highlight particular features to facilitate interpretation and analysis.
