These thematic mappers take images in multiple wavelengths of electro-magnetic radiation (multi-spectral) and are usually found on Earth observation satellites, including (for example) the Landsat program or the IKONOS satellite.
Ovi tematski maperi rade snimke u višestrukim valnim duljinama elektromagnetske radijacije (multispektralno) pa se obično nalaze na satelitima za osmatranje Zemlje uključujući (primjerice) Landsatov program satelita IKONOS.
