Satellite images and Aerial Photos in support of cadastral maps provide the foundation for subsequent mapping projects to meet the needs of many crucial public services including tax assessment, emergency management, public works, Homeland Security planning and allowing individuals and businesses to raise capital based on property values.

Satellite and Airborne Remote Sensing technology providing GIS mapping solutions help agencies meet their primary responsibilities of ownership registration, parcel mapping, real property valuation, and data access and provides the tools to more efficiently collect, convert, improve map data and accurately assess properties for public use.

Remote sensing technology supports cadastral mapping of these records in the form of maps that can be updated because satellite and aerial remote sensed images provides details with respect to various features such as roads, railway line, streams, reserves, forest boundary, plantation crops and other different agricultural fields of the study area with higher spatial resolutions from satellite sensors such as GeoEye-1, QuickBird, IKONOS and SPOT-5 and medium resolution satellite images from satellite sensors Landsat and ASTER can provide multispectral image data for land cover and land use detection of projected areas.

Satellite images and Aerial Photos which forms the base for the generation of action plan maps, if used in the background of intelligent cadastral vector data, can improve the details of the thematic maps as well as action plan maps. It also helps in the monitoring of land cover changes that can be identified by detailed change detection processing procedures and implemented in the GIS cadastre mapping project.

The cadastral map has four main purposes:
• Provides a cartographic record of official and sometimes private land surveys and subdivisions.
• Facilitates the administration and transfer of land ownership.
• Records land ownership.
• Assists in the valuation and taxation of land.

High resolution satellite imagery can benefit cadastre mapping to:
• Create DEMs to support production of ortho images
• Identifying, interpreting, extracting and mapping as well as rural settlement detail, using stereoscopic photogramme try and image processing.
• Recognizing, classifying, mapping and monitoring land cover and land use changes for cooperative farms and forestry conservation.
