To understand how raster works it helps to construct one from scratch.

Behind the scenes a numpy.ndarray does all the heavy lifting. In order to work with raster data we will be using rasterio and later geowombat. This is in contrast to a vector model that may or may not have a value associated with the geometric primitive. Implicit in a raster data model is a value associated with each cell or pixel. But a regularly spaced array of marked points may be a better analogy since rasters are stored as an array of values where each cell is defined by a single coordinate pair inside of most GIS environments. A raster can be thought of as a special case of an area object where the area is divided into a regular grid of cells. Raster datasets are commonly used for representing and managing imagery, surface temperatures, digital elevation models, and numerous other entities. Remote Sensing Coordinate Reference SystemsĪ raster data model uses an array of cells, or pixels, to represent real-world objects.
