MORE Maps Service Purpose User Perspective Urban area maps and urbanization change detection over MODIS data User Perspective Browse MODIS catalogue to select input images Request processing over an AOI Directly download output maps via FTP

MORE Maps Service Service Provider Connected services GEO-K (Rome, Italy) Connected services MEEO provides: MODIS Data Catalogue Image Pre Processing clipping, calibration and geo-location remapping GEO-K provides: MORE Maps service backend

MORE Maps Service Processes both terra and aqua datasets Processes both day and night acquisitions but only in pairs No mixed selection Radiometric calibration extent Outputs only +/- 40° from nadir line Commercial service Unrestricted access with payment confirmation

SSE Operations SSE Order Order parameters AOI for image pre processing output format ENVI, GeoTIFF or JPEG Urbanization Change Map (and classification maps) Retrieve results directly from the service provider server over FTP

Order notes The AOI for image pre processing is optimized by the pre processing component Intersection of the datasets and AOI Result coverage area may be smaller than AOI if a dataset does not cover it entirely Calibration extent shall be taken into account when defining AOI +/- 40 degrees from nadir line Do not select AOI near dataset borders
