What is Photogrammetry?

Photogrammetry uses photographs from at least two different vantage points. It obtains depth and perspective because of separate points of observation.

Sentinel 2 Bands and Combinations

Sentinel 2 has a total of 13 bands. Each band is 10, 20 or 60 meters in pixel size. This includes red, green, blue, near infrared and short infrared bands.

Landsat 8 Bands and Band Combinations

We list Landsat 8 bands as well as popular band combinations which includes coastal, blue, green, red, NIR, SWIR-1, SWIR-2, cirrus and two thermal bands.

50 Satellites in Space: Types and Uses of Satellites

A list of the 50 most iconic satellites put up into space to monitor our planet. We show the uses and types of satellites like weather and GPS satellites.

Selective Availability in Global Positioning System (GPS)

Selective availability is the intentional degradation of GPS signals. When selective availability was enabled, this added error horizontally and vertically to GPS signals.

Sentinel Satellites of the Copernicus Programme

Copernicus is the world’s largest and most ambitious Earth observation program in existence today with its Sentinel satellites taking center stage.

Remote Sensing of the Environment: Local and Global Environmental Issues

As our population grows and climate is at risk, remote sensing of the environment solves large-scale environmental issues for the land, ocean and atmosphere.

DigitalGlobe Satellite Imagery: Worldview, GeoEye and IKONOS

If you want the sharpest satellite imagery in the world, harness the power of DigitalGlobe imagery. Each pixel in a Worldview-3 image is about 31 cm.

IKONOS Satellite Imagery: First Commercial Space-based Imaging

IKONOS provides panchromatic, natural-color, color-infrared and stereo images for cartographic, remote sensing and photogrammetric applications.

SRTM Shuttle Radar Topography Mission

During an 11-day mission, Space Shuttle Radar Topography (SRTM) mission captured Earth’s elevation at 1 arc-second (30 meters) for over 80% of the Earth.
