Vector data comprises of vertices and paths. These include points (hospitals), lines (roads) and polygons (areas).

* 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. Rasters include satellite and UAV/UAS imagery, elevation data models, etc. Common raster file formats are:
* .jpeg, .png, .tiff, .bmp    [[Image:RASTER Example.png|350px|left]]<div align="center"></div>
