Spatial data management consists of modeling and storing data acquired through geospatial methods. There are two main types of spatial data models: raster and vector. Raster models divide space into grid-cells, making them ideal for continuous data like satellite images. In contrast, vector models represent spatial features using geometric shapes such as points, lines, and polygons, allowing for a precise representation of discrete entities. This distinction is crucial for effective data processing and analysis in GIS applications.
The two primary categories for spatial data modeling in geospatial domains are raster data models, which use a grid-based approach, and vector data models that represent entities using geometrical shapes.
Raster models are effective for continuous geospatial data, like satellite imagery, whereas vector models provide a clearer depiction of discrete spatial entities through points, lines, and polygons.
