Service Description: These data are panchromatic satellite data from the French SPOT-5 satellite. They represent a black-and-white "picture" of Earth from the satellite using 5-meter pixels (5m x 5m squares) as the minimum unit for imaging. The collection dates are mostly during the leaf-on season in 2004. Two scenes are from winter collects and snow/ice can be seen. This dataset was created through orthorectification of SPOT imagery using USGS Digital Orthophoto Quadrangles and Maine DEMs in ERDAS OrthoBASE 8.7. The orthorectified imagery was then warped using Space Imaging's proprietary Autowarp software. Autowarp computes tie points between two images based on correlation between similar points in the images and then applies a locally varying warp based on the tiepoints. The program was given an initial set of ground control points to create a coarse quadratic warp which was then refined through the addition of more points selected by the program. This work was done by Space Imaging and Sanborn staff. Certain high-elevation areas were further orthorectified by i-cubed to reduce horizontal error. Color balancing for the mosaic was done using GIMP image processing software by Maine DEP GIS staff. Note that balancing was done to enhance vegetated areas. In most cases, this means loss of contrast in urban areas. The raw data are much darker, but would provide more detail in urban areas than these processed data (at the expense of loss of contrast in vegetated areas). These data are part of the MELCD 2004 landcover and impervious mapping project for Maine. The data are LICENSED to the following entities: -Federal Government organizations when working with Maine on joint projects -All State Government departments and agencies within Maine -Regional county and local governments within Maine -K-12 schools, State Colleges and Universities within Maine. These data were the base imagery for the MELCD 2004 project. They were merged with LandSat TM data to create sharpened multispectral data for landcover mapping.
