Introduction to radiometric calibration

Introduction to radiometric calibration

Absolute radiometric calibration is a technique used to ensure the accuracy of the radiance values measured by satellite sensors. Radiance is a measure of the amount of light that is reflected from the earth's surface, and is an important factor in the interpretation and analysis of satellite imagery. To perform

Satellite images, to see or not to see

Usually talking about earth observation we talk about optical satellite images similar to our family photos. On top of these optical images, satellite data can be produced with other bands such as synthetic aperture radar, also known as SAR or by using several different bands for example to detect heat,

The Fastest Way to Extract Values from Geospatial Data

A considerable part of what we do at Terramonitor can be summed up by the extract, transform, load (ETL) paradigm. This happens both in internal processes and in those that are externally triggered. And sometimes those processes are too slow.
