All the assessor plats for a municipality scanned into a GIS file create which type of data structure?

The scanning of assessor plats into a GIS file creates a raster data structure. This is because raster data is composed of pixels or grid cells, where each cell holds a value that represents information such as color, intensity, or in this case, the characteristics of the assessor plats. Since scanned images consist of a large number of individual pixels representing the visual information of the plats, they are inherently raster in nature.

Raster data is commonly used for representing continuous data, such as aerial imagery and satellite photographs, where each pixel contains information about a specific area. This contrasts with vector data structures, which represent discrete features using points, lines, and polygons that are defined by their coordinates.

Thus, when assessor plats are scanned and stored in a GIS, they are converted to a raster format, effectively capturing the spatial distribution of the information contained in those plats.
