PRODUCT SPECIFICATIONSSpace Imaging’s IKONOS GEO 1-meter Black-and-White and 4-meter Multispectral imagery specifications:SPATIAL RESOLUTION1-meter panchromatic (black & white) & 4-meter multispectral (color).PANCHROMATIC 0.44 – 0.90 micrometers COLOR Band 1 (Blue) 0.45 – 0.53 micrometers Band 2 (Green) 0.52 – 0.61 micrometers Band 3 (Red) 0.64 – 0.72 micrometers Band 4 (Near IR) 0.77 – 0.88 micrometers SCENE SIZECustomer specified area of interest (AOI). Minimum order is 100 sq. km.SENSOR REVISIT TIME1-3 daysACCURACYAverage 23.8-meter RMS error in horizontal accuracy, excluding effects of terrain displacementLEVEL OF CORRECTIONSystematically corrected (map-oriented). The correction process removes image distortions introduced by the collection geometry and re-samples the imagery to a uniform ground sample distance and a specified map projection.DELIVERY TIMEUpon entering space imaging's order system the imagery shall be delivered in part (shipped as acceptable images are acquired) or in whole within :Archive Date : 30 days New collection : 60 days for AOIs less than 500 sq.km New collection : 120 days for AOIs greater than 500 sq.km The delivery time cannot be guaranteed due to unfavourable atmospheric conditions outside of Space Imaging’s control. DYNAMIC RANGEData is collected at 11 bits per pixel, but the product can be delivered as 11 bits per pixel (in two 8 bytes) or 8 bits per pixel.CLOUD COVERThe maximum allowable cloud cover is 20%. ORDER CANCELLATIONSIf order is cancelled due to late delivery, no fees will be assigned. If order is cancelled prior to agreed upon delivery term. 25% of order value charged if cancelled after 3 days. 50% of order value charged if cancelled after 30 days.The snapshot sample of this satellite imagery is as follows: ikonos The data will be delivered in wide-commonly used geo-referenced raster data format, such as Geo-TIFF, ECW, ASCII Grid or Northwood Geoscience Grid. |
