22. GIS Data Structure GIS Maps Tables Maps Linked to Data

23. GIS Data Structure

24. Irregular Tile Boundaries CDOT Region boundaries

25. Spatial Data Value Shape Location Spatial Reference Object’s data, information or description in tables Object’s external surface or outline on a map or drawing Object’s place on a map that represents the real world position Object's relationship to the objects around it

28. Spatial Data Value Shape Location Spatial Reference Basic geometric figures Points Line 2 or more Points Polygon 3 or more Lines

34. Raster GIS Data Layer Note Grid/Raster Cell Size Rich mixture of data Fuzzy boundaries

39. Grid GIS provides more data variations and less precise edges. Missing data easily identified. Vector GIS provides better edges and sharp changes in data, however, data is constant for entire area. Data Variation Greater Data Variation Missing Data Sharp Edges Single Value
