WER A Figure 3. DMSP satellites collect visible and thermal infrared imagery in global coverage along a 3000-mile swath with the Operational Linescan System (OLS.) Users within SPIDR can select DMSP imagery by date and geographical position anywhere on earth. DMSP images are then returned along with the satellite path and a button tool for navigating the database, i.e., by 'flying' the satellite about the globe.
