These layers are overlaid on high of one another, making a composite view of the geographic space. The great thing about layers is that you could select which layers to show, permitting you to concentrate on the data that’s related to your particular wants.

• Options: Inside every layer, geographic information is represented as options. Options are the person parts that make up the layer. They are often factors (e.g., the placement of a properly), traces (e.g., a highway or river), or polygons (e.g., a constructing footprint or a rustic boundary). Every function is related to a selected location on the Earth’s floor, outlined by its geographic coordinates (latitude and longitude).

• Attributes: Maybe probably the most highly effective facet of a GIS map is the flexibility to retailer and handle attribute information related to every function. Attributes are descriptive traits that present details about the function. For instance, a highway function may need attributes comparable to its identify, size, floor kind, and visitors quantity. A constructing function may need attributes comparable to its deal with, variety of flooring, and occupancy kind. These attributes are saved in a database and linked to the corresponding geographic function, permitting for highly effective querying and evaluation.
