Geographical information system and agriculture Research Paper

Geographical information system and agriculture - Research Paper Example In the long run, commonly referenced data can be superimposed to determine relationships between data components. Geographic information system (GIS) software applies relational database management technologies to consign a series of attributes to every spatial characteristic (Longley et al 86). Ordinary aspect identification keys are used to associate the spatial and attribute data among tables. For example, a soil polygon can be associated to a chain of database tables that explains chemical composition, its mineral, crop yield, slope, land use suitability, and other features. Another aspect of Geographic information system (GIS) is that it provides the capability to coalesce series of data into a multiple data layer that may later be a base layer in the database. For instance, demography, slope, wetlands, hydrography, soils and land use can be merged to develop a solitary layer of proper hazardous waste storage sites (Longley et al 140). These data, in turn, may be integrated into the listing database of local government and applied for regulatory and planning evaluations.GIS software normally allows for two kinds of data. Some use raster data i.e. satellite imagery while others use vectors to represent features on the surface of the earth. Most systems allow for complete integration of both types of data (Pierce and David, 11). A GIS can be used to explain basic locational questions such as what is positioned at a given level on the earth surface; or where is the exact element located? At the same time, soils data across the entire watershed can be asked to determine the distribution of regions with hydric soils of huge than 100 acres and are linked to key river system (Pierce and David, 15). Geographic information system (GIS) is becoming the dais of choice for mixing and analyzing enormous range of data in the field of agriculture due to the ability to analyze those data flow and display
