Conversion Between Data Models What GIS data types exist? Spatial data observations focus on locations.. Every house, every tree, every city has its own unique latitude and longitude coordinates. The two primary types of spatial data are vector and raster data in GIS. The main difference between raster and vector data is that the raster data represents data as a cell or a grid matrix while vector data represents data using sequential points or vertices. Geographic Information System (GIS) is a computer-based tool or technology to manage, analyze and display geographically referenced information. Because raster data represent square areas, they describe interiors rather than boundaries as is the case with vector data. Vector data are excellent for capturing and storing spatial details, while raster data are well suited for capturing, storing, and analyzing data such as elevation, temperature, soil pH, etc.

When designed appropriately, these algorithms even increase the processing time, provided they utilize the R-tree and k 2 – raster. Considering that before, GIS software packages first converted vector datasets to raster datasets before including them in a raster algorithm, hence wasting time, as it were, the framework developed by the

building, road, vegetation, 9.1. Lesson: Raster to Vector Conversion¶. Converting between raster and vector formats allows you to make use of both raster and vector data when solving a GIS problem, as well as using the various analysis methods unique to these two forms of geographic data. The old GIS adage “raster is faster, but vector is corrector” comes from the two different fundamental GIS models: vector and raster.
