A raster data type is, in essence, any type of digital image represented by reducible and enlargeable grids. Anyone who is familiar with digital photography will recognize the Raster graphics pixel as the smallest individual grid unit building block of an image, usually not readily identified as an artifact shape until an image is produced on a very large scale. The three types of GIS Data are-spatial, –attribute, & —metadata.

GIS DATA TYPES. The basic data type in a GIS reflects traditional data found on a map. Accordingly, GIS technology utilizes two basic types of data. These are: Spatial data. describes the absolute and relative location of geographic features. Attribute data. describes characteristics of the spatial features.

2008-06-22 · GIS DATA TYPES: 1. Attribute Data: The attributes refer to the properties of spatial entities. They are often referred to as non-spatial data since they do not in themselves represent location information. This type of data describes characteristics of the spatial features. These characteristics can be quantitative and/or qualitative in nature.
