What is attribute data in GIS?
Attribute Data.
Attribute data are the information linked to the geographic features (spatial data) that describe features.
That is, attribute data are the “[n]on- graphic information associated with a point, line, or area elements in a GIS.”What are the attributes of geospatial data?
Geospatial data typically combines location information (usually coordinates on the earth) and attribute information (the characteristics of the object, event or phenomena concerned) with temporal information (the time or life span at which the location and attributes exist).
What is the difference between geographic and attribute data?
What is important is geographic data permit us to define the location of an object (i.e., your home) on the surface of the earth.
In addition to the geographic data that define the location of your home are the attribute data that describe the various qualities of your home.The two major types of GIS file formats are raster and vector.
Raster formats are grids of cells or pixels.
Raster formats are useful for storing GIS data that vary, such as elevation or satellite imagery.
Vector formats are polygons that use points (called nodes) and lines.
