USA: The MapMart division of IntraSearch Inc. unveiled a new interface on its MapMart online mapping portal where satellite imagery customers can search, preview and order high-resolution data from DigitalGlobe, GeoEye, SPOT and KOMPSAT. MapMart (https://www.mapmart.com) portal allows customers to browse imagery from a variety of sources, task new acquisitions, request custom processing, and acquire imagery from a single source.
“Our goal in creating the MapMart mapping store is to provide geospatial data users with the convenience of obtaining whatever satellite imagery, aerial photography, and elevation data they need during a single online session,” said MapMart President Michael Platt.
MapMart introduced its online store in 1997 giving customers a map-based interface where the availability of numerous raster and vector map products could be researched with the click of the mouse on a specific geographic area of interest. Terabytes of geospatial data sets including U.S. NAIP imagery, USGS DOQQs, DEMs, Landsat-derived products and the entire IntraSearch archive of aerial photography dating from the 1930s were among the initial offerings. MapMart recently added Microsoft Virtual Earth’s UltraCam high-resolution photography and continues to expand its offerings and strengthen its position as the go-to resource for geospatial data and software.
This year’s addition of high-resolution data rounds out the satellite imagery catalog. Powered by .NET technology, the new MapMart satellite search 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 data sets:
• DigitalGlobe QuickBird and WorldView-1
• GeoEye IKONOS and GeoEye-1
• 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.
