Best Handheld GPS Receivers

Whether you’re hiking, geocaching, fishing, snowmobiling, or hunting, we are here to guide you through some of the best handheld GPS today.

Hyperspectral Imaging from Space

Hyperspectral imaging takes a spectrum of light and divides the light into hundreds of narrow spectral bands. For example, Hyperion has 242 bands at 30m GSD.

GOES vs POES (Geostationary and Polar Operational Environmental Satellites)

GOES and POES are both operational environmental satellites. But they actually share more in common such as their 40+ year legacy in space.

What is Photogrammetry?

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

Worldview Satellite by DigitalGlobe

DigitalGlobe’s cutting-edge high resolution Worldview satellite carves out ridiculously crisp imagery at 31 cm in 8 spectral bands.

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.
