==Vector Data==__NOEDITSECTION__
Vector data is not made up of a grid of pixels. Instead vectors are comprised of vertices and paths. These include points (locations), lines (Roads) and polygons (Areas).
Vector data can be in various data formats, these include:
* KML, KMZ (often used in Google Earth or other web GIS programs)
* Shape File (.shp) this is the standard file format for vector data and will contain only a single dataset
* Geodatabase (.gdb) these will contain multiple datasets simultaneously.

==Raster Data==__NOEDITSECTION__
Raster data is made up of pixels (also referred to as grid cells). Raster’s often look pixelated because each pixel is associated with a value or a class.
