What Is GIS ?
GIS - A computer system for gathering, storing, verifying, and displaying information about locations on the surface of the earth is known as a geographic information system (GIS). Streets, buildings, and other types of data, as well as flora, can all be displayed on a single map using GIS. This makes it simpler for people to see, evaluate, and comprehend patterns and correlations.
Any pixelated (or gridded) data that has a defined geographic location assigned to each pixel is referred to as raster data. A pixel's value can be categorical or continuous (for instance, elevation) (e.g. land use).
Specific characteristics on the surface of the Earth are represented by vector data structures, which also provide those features properties. Vertices, which give a spatial object its shape, are made up of discrete geometric locations (x, y values) known as vectors.
An assortment of linked feature classes with a shared coordinate system make up a feature dataset. Feature datasets are used to make it easier to create controller datasets, also known as extension datasets, like a utility network, topology, or parcel fabric.
