High-resolution satellite images in one portal

MapMart has unveiled a new interface on its MapMart online mapping portal. It has now added a portal where satellite imagery customers can search, preview and order high-resolution satellite image data from DigitalGlobe, GeoEye, SPOT and KOMPSAT.

MapMart portal allows customers to browse imagery from a variety of sources, task new acquisitions, request custom processing, and acquire imagery from a single source. The new interface allows users to define an area of interest by entering coordinates or drawing a polygon on a Virtual Earth map screen. The user can also sort the search results by specific satellite, acquisition date and cloud cover. Available archived scenes can be previewed instantly in thumbnail formats onscreen.

The MapMart satellite imagery interface currently includes the following high-resolution satellite data sets:

• DigitalGlobe QuickBird and WorldView-1
• GeoEye IKONOS and GeoEye-1
• SPOT-1—5
• Korean KOMPSAT
• Harris Corp. CONUS 10-meter and Globe15 15-meter from Landsat 7
• Landsat GeoCover 15-meter
• Planetary Visions 1-KM imagery
• Numerous high resolution aerial imagery

Online orders for DigitalGlobe, GeoEye, SPOT and KOMPSAT imagery are orthorectified, colour-balanced and quality checked by IntraSearch photogrammetrists. Other custom processing options are available, including format conversion and selection of map projection. Orders are typically delivered within five business days via FTP or external drive depending on file size. Most archived medium-resolution products derived from Landsat imagery are available for immediate purchase and download from the site.
