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 You Need To Know: Earth Satellite List

Today I’m going to show you the largest Earth satellite list ever put together. From oceans to weather, here’s our list of the 50 most iconic 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, this poses new challenges to monitoring the environment and climate change. Remote sensing of the environment helps solve environmental issues for the land, ocean, atmosphere and climate change.

DigitalGlobe Satellite Imagery: Worldview, GeoEye and IKONOS

If you want the sharpest satellite imagery in the world, then you should harness the power of DigitalGlobe satellite imagery. Each pixel in a Worldview-3 image is about the size of home plate on a baseball diamond. That’s 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.
