Satellite Imagery
Remotely sensed satellite imagery is becoming increasingly common as satellites equipped with technologically advanced sensors are continually being sent into space by public agencies and private companies around the globe.

Satellite Imagery, GIS data sources, & Image Archives - if you require data or imagery these are some fine resources and portals available for your use.

Satellite Imagery: Digital data obtained from sensors carried in satellites. It includes collecting data both in the visible and non-visible portions of the electromagnetic spectrum.

More satellite imagery support
Improved support for RADARSAT-2 and SPOT 5 imagery, and added support for others.

satellite image A picture of the earth taken from an earth-orbital satellite. Satellite images may be produced photographically or by on-board scanners (e.g., MSS). scale See map scale.

[edit] Satellite Images
Satellite images are available too, users can zoom in until they see cars and, in some cities, people can be seen walking in the street (appearing as tiny black dots).

Even aerial and satellite imagery can be incorporated into a GIS and viewed along with other data for the same area, as long as the ground extent of the image can be identified.

If color quality of satellite image color composites seems to appear poor, run r.colors on the selected satellite channels.

For example, digital satellite images can be analyzed to produce a map like layer of digital information about vegetative covers.

Aerial photography differs from satellite imagery in that the results are almost instantaneous and require only developing, ...

Satellite imagery such as Landsat TM and SPOT provide multispectral images of the earth, some containing seven or more bands.

Imagine is a specialized image processing software application developed mainly for analyzing remotely sensed satellite imagery. ArcGIS supports Imagine files with its Imagine Image Format Extension.

For example, digital satellite images generated through remote sensing can be analyzed to produce a map-like layer of digital information about vegetative covers.

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.
