Sophisticated generation and calculation of Vector entities from Raster Data?
Geographic Information SystemsWhat is the difference between vector data and raster data?
Vector data represents geographic data symbolized as points, lines, or polygons. Raster data represents geographic data as a matrix of cells that each contains an attribute value.
What is raster and vector data model?
• RASTER DATA MODEL. A spatial data model that uses a grid and cells to represent the spatial variation of a feature. • VECTOR DATA MODEL. A data model that uses points and their x-, y- coordinates to construct spatial features.
What is raster data model in GIS?
From wiki.gis.com. Raster data models present information through a grid of cells. Raster grids are usually made up of square or rectangular cells. Unlike vector data models, which show geographic data through points, lines, or polygons, raster data is displays one value in each cell.
