Natural resource-oriented users will find that up-to-date satellite imagery, aerial photographs, as well as topographic, climatic and hydrographic data are all useful in environmental planning and resource monitoring.
Image map - (1) A map created from aerial photographs or satellite images by assembling them spatially (i.e. making a mosaic), correcting them geometrically (i.e. georeferencing and scaling) and adding cartographic symbols and place names, ...
These may include such items as digital terrain data, orthophotographs, and satellite imagery. These data may provide tremendous capability, but must be managed in ways different from traditional vector information.
(GTC) are developing a prototype GIS tool that integrates satellite imagery with layers of statewide GIS datasets. In addition, standard business process and site-selection methods are being created in the hopes of developing new industry standards.
National government users that employ aerial photography or satellite imagery in mapping or intelligence activities use Bentley Descartes. These include military, census, cadastre, and mapping agencies.
Can a property ownership map be related to a satellite image, a timely indicator of land uses? Yes, but, because digital data are collected and stored in various ways, the two data sources may not be entirely compatible.
background image: A satellite image or air photo that serves as a backdrop for display and registration purposes only rather than as a layer for analysis with the GIS.
