Difference between a vector and raster data model
Vector-represent geographic features us points, lines, and polygons
Raster- represent geographic features as a grid of pixels, where each pixel has a value representing an attribute.
Determine when a vector data model is more appropriate than raster data.
Vector data models are more appropriate for representing features with discrete boundaries, such as roads, buildings, and political boundaries.
They are also better for storing data with high accuracy and precision, such as property lines and utility networks.
Determine when a raster data model is more appropriate than vector data
Raster- more appropriate for representing continuous data, such as elevation, temperature, and precipitation.
They are also better for storing data with a large number of attributes,such as satellite imagery.
