Optical satellite imagery are acquired in the optical part of the spectrum. This covers the visible colors but also the infrared part. Optical imagery can be displayed in natural color (like how we would see it ourselves with the human eye) and in false color (with infrared information). False color imagery are useful for agricultural (crop classification), environmental (vegetation health) and geological applications (soil mapping).
Geoserve has access to all important earth observation satellites. These satellites collect imagery at various spatial resolutions. The most detailed optical imagery have a resolution of just 31cm. In below tables the specifications are given for the most commonly used images.
Very High Resolution (table with images with a resolution of 31cm to 1 meter)
Medium Resolution (table with images with a resolution lower than 1 meter)
