WebApr 7, 2024 · File Formats for Raster Spatial Data The generic raster data model is actually implemented in several different computer file formats: • GRID is ESRI’s proprietary format for storing and processing raster data • Standard industry formats for image data such as JPEG, TIFF and MrSid formats can be used to display raster data, but not for ... WebA vector representation is composed of three main elements: points, lines, and polygons. Points are spatial objects with no area but can have attached attributes since they are a single set of coordinates (X and Y) in a coordinate space. Lines are spatial objects made up of connected points (nodes) that have no width.
