Geographic Information System or GIS is technology that provides a radically different way to produce and utilize the maps necessary to manage our communities and industries. GIS helps create intelligent super maps through which sophisticated planning and analysis can be carried out at the mere touch of a button.GIS aerial maps can greatly enhance a GIS mapping project. Aerial imagery is really a powerful visual aid and serves as a way to obtain derivative information such as land cover, terrain, change detection, or vegetation.

Today you can find perhaps thousands of geospatial applications in use. Organizations, agencies and companies across the world use the technology to transform manually produced maps and associated descriptive records into digital databases. Once an instrument that was affordable and then the largest organizations, geospatial systems and GIS aerial maps have grown to be a cost effective option for even the smallest organizations.

Geographic information system technology is widely used for scientific investigations, natural resource management such as forestry, agriculture, mining, coal and oil exploration, environmental impact assessment, and urban planning.

GIS and GIS Aerial Maps may be used in a wide range of activities, such as for example: GIS base mapping, corridor mapping, land cover classification, urban development, pre and post 2D/3D seismic surveys, Environmental Impact Studies (EIS), environmental monitoring, coastal erosion studies, property and tax mapping, and flood analysis. You likely can even think about other uses for GIS not listed here, though it sounds cliche; the possibilities truly are almost endless.

Some GIS projects are hindered by coordinate problems of different image and vector data layers, which are caused by one or a mix of the following: Improper orthorectification of satellite or aerial image mosaics. Poor quality GPS derived ground control points (GCPs). Improper rectification of digital source raster maps. Importation of vector data or shape files for source data with incorrect coordinates. Improper use of units or unit convergence factors for source data. Utilization of source data from the corrupt coordinate database.

The key advantage to GIS is the ability to share maps, such as GIS aerial mapping. Additional resources and federal agencies, alongside utility companies, which typically create their own respective maps, can share maps with one another. This not merely saves money, but provides the ability to create a huge selection of new maps, many of which may haven't existed before, for minimal cost. With such widely available and easy to use tools open to make GIS aerial maps, there really is no reason you should not be using this technology together with your aerial photographs.
