In this course, the second in the Geographic Information Systems (GIS) Specialization, you will go in-depth with common data types (such as raster and vector data), structures, quality and storage during four week-long modules: Week 1: Learn about data models and formats, including a full understanding of vector data and raster concepts. GIS DATA TYPES GIS technology utilizes two basic types of data. These are: 1) Spatial data: describes the absolute and relative location of geographic features. 2) Attribute data: describes characteristics of the spatial features.

• Simple data structures Overlay and combination of maps and remote sensed images easy • Some spatial analysis methods simple to perform • Simulation easy, because cells have the same size • Technology is cheap Disadvantages of Raster Data Structures: • The use of large cells to reduce data volumes A raster data type is, in essence, any type of digital image represented by reducible and enlargeable grids. Anyone who is familiar with digital photography will recognize the Raster graphics pixel as the smallest individual grid unit building block of an image, usually not readily identified as an artifact shape until an image is produced on a very large scale. The three types of GIS Data are-spatial, –attribute, & —metadata. spatial data. vector data Point Data — layers containing by points (or “events”) described by x,y (lat,long; easting, northing) Line/Polyline Data — layers that are described by x,y points (nodes, events) and lines (arcs) between points (line segments and polylines) Data types.

In ArcGIS, the geometry data type indicates the type of geometry—point, line, polygon, multipoint, or multipatch—the table stores. The field stored as geometry type is called SHAPE when created through ArcGIS. New feature class of type polygon Geometry is the data type used by ArcGIS.
