GIS is a system of hardware and software used for storage, retrieval, mapping, and analysis of geographic data.
- Layers are files that store symbology and display information for a given vector or raster data set. The layer does not actually contain the data, but points to its physical location.
- Vectors are data models based on a coordinate system used to represent linear geographic features.
- Rasters are data models composed of a grid of cells which represent geographical features, the value in the cell represents t the attribute of the feature.
- Attribute s are information (text or numeric) about a geographic feature generally stored in a table that is linked to the feature which might include names, distances and depth.
- Features are objects in a landscape or on a map.
- Geospatial data – Geographic data is the data or information that identifies the geographic location of features and boundaries on Earth. Spatial data is usually stored as coordinates and topology, and is data that can be mapped. Spatial data is often accessed, manipulated or analyzed through
