GIS Mapping Basics
Geographic Information Systems, or GIS, are systems that gather, organize and analyze data in terms of its geographical location. GIS mapping uses computer software to register data from land surveys, aerial and satellite photography, as well as a wide variety of other sources. This data is then combined and represented in map form.By layer data in geographical form, Geographic Information Systems mapping can tell us a lot about a particular location that we didn’t know before. The data input can include things like, rivers, mountains, streams, roads, gas stations, highways, bus stops, etc. Statistical data like census figures and other demographical information can also be fed into a GIS to produce different geographical analyses. The kind of data you input into a GIS depends on the type of analysis you are trying to acquire about a given location. For example, you can input a city’s crime stats onto a geographic Read more…
GIS Aerial Maps – Discover the Many Uses
Geographic Information System or GIS is technology that offers a radically different way to produce and use the maps required to manage our communities and industries. GIS helps create intelligent super maps through which sophisticated planning and analysis can be performed at the mere touch of a button.GIS aerial maps can greatly enhance a GIS mapping project. Aerial imagery is a powerful visual aid and serves as a source of derivative information such as land cover, terrain, change detection, or vegetation.Today there are perhaps thousands of geospatial applications in use. Organizations, agencies and companies throughout the world use the technology to transform manually produced maps and associated descriptive records into digital databases. Once a tool that was affordable only to the largest organizations, geospatial systems and GIS aerial maps have become a cost effective option for even the smallest organizations.Geographic information system technology is widely used for scientific investigations, natural Read more…
