Satellite Images Provider and Analysis

SEKALA acts as a satellite image provider and is able to assist organizations to enhance, rectify, mosaic and interpret satellite images.

As part of this service, SEKALA is able to:

  • Search satellite image archives and provide recommendations on suitable images to purchase.
  • Process satellite images with terrain correction, atmosphere correction, and enhancement.
  • Classify satellite data to deliver information you need, such as maps of land cover and land use, soils, habitats and wetlands.
  • Detect change in multi-temporal images, such as deforestation, and other disturbances.
  • Provide digital elevation models

All of our base satellite image products are delivered ready for seamless integration into Geographic Information Systems, AutoCAD software or other planning tools.

SEKALA can also provide customized large-scale photographic prints of purchased satellite imagery.

In collaboration with EDPMedia, SEKALA can provide the following Digital Globe products:

Quickbird
DigitalGlobe’s QuickBird satellite offers sub-meter resolution imagery (65 cm resolution), high geolocational accuracy, and large on-board data storage. With global collection of panchromatic and multispectral imagery, QuickBird is designed to support a wide range of geospatial applications.

Ikonos
The IKONOS satellite is the world’s first commercial satellite to collect panchromatic (black-and-white) images with .80 m resolution and multispectral (color) imagery with 3.2-meter resolution. Imagery from the panchromatic and multispectral sensors can be merged to create .80 m color imagery (pan-sharpened). IKONOS has a revisit time of once every three days.

WorldView 1
WorldView 1 was launched in September 2007. The high-capacity, panchromatic imaging system features half-meter resolution imagery. Operating at an altitude of 496 km WorldView-1 has an average revisit time of 1.7 days and is capable of collecting over one million km2 per day of half-meter imagery. The satellite is also equipped with state-of-the-art geolocation accuracy capabilities and exhibits stunning agility with rapid targeting and efficient in-track stereo collection.

WorldView 2
WorldView-2 was launched in October 2009. Operating at an altitude of 770 km, WorldView-2 provides 46 cm panchromatic resolution and 1.85 m multispectral resolution. WorldView-2 has an average revisit time of 1.1 days and is capable of collecting
 up to 1 million km2 of 8-band imagery per day.

WorldView 3
WorldView 3 was launched in 2014. Operating at an expected altitude of 617 km, WorldView-3 provides 31 cm panchromatic resolution, 1.24 m multispectral resolution, 3.7 m short-wave infrared resolution, and 30 m CAVIS resolution. WorldView-3 has an average revisit time of <1 day and is capable of collecting up to 680,000 km2 per day.

Geoeye
GeoEye-1 was launched in September 2008 and it collects the world’s highest resolution and most accurate commercial Earth imagery. The GeoEye-1 satellite collects images at .41-meter panchromatic (black & white) and 1.65-meter multispectral resolution. The satellite can collect up to 350,000 square kilometers of pan-sharpened multispectral imagery per day. This capability is ideal for large-scale mapping projects. GeoEye-1 can revisit any point on Earth once every three days
or sooner. GeoEye-2 became operational in 2013. GeoEye-2 has 34 centimeter resolution and it surpasses the performance of GeoEye-1 in resolution, capacity, and agility.
