What Is Remote Sensing?
In simple terms, remote sensing is the act of detecting objects in an area and measuring their movements from space. Remote sensing detects and monitors the physical characteristics of the ground by measuring its reflected and emitted radiation from a distance. The sensors used for remote sensing are generally mounted on satellites, aircraft and more…

Starship conducts maiden launch – clears launch site and first stage flight
The most powerful rocket in history launched on its second attempt Thursday, the first major step to making life multi-planetary. Liftoff of Starship from Starbase, Texas came after an uneventful countdown, with only a couple of short holds before roaring off the launch mount. The vehicle lost several Raptors during first stage ascent before starting…

What Is High Resolution?
High resolution refers to the spatial resolution size of a satellite image. In simple terms, the resolution type will determine the clarity of your optical image. The smaller the pixel size, the more “clear” your image will look. High resolution has a smaller size per pixel offered by a satellite provider. The size of a…

What are indices?
Indices are calculated using the multispectral bands. These calculations result in the outputs being in the form of an index with values between 0-1. At the same time, the indices provide additional information about the ground surface being imaged. There are four EarthCache outputs that are under the indices umbrella: NDVI, MSAVI2, EVI and NDWI2.…

What Is Spectral Resolution?
Spectral resolution is the ability of a satellite sensor to detect distinct ranges of wavelengths in the electromagnetic spectrum. Essentially the radiation that the sensors receive from the ground can be detected across various wavelengths, including ultraviolet, visible (red, green, blue), infrared and microwave. Ranges of wavelengths are defined as bands in remotely sensed imagery.…

What Is Spatial Resolution?
Resolution refers to the spatial resolution a data product has. Spatial resolution can be defined as the amount of data on the ground a single image pixel represents. A 50cm spatial resolution product has 1 pixel representing a 50cm x 50cm area on earth. A 10m spatial resolution product has 1 pixel representing a 10m…
