  • 19. Three perspectives Map Data Models
  • 20. The Data • A single data repository: the Geodatabase • Every geographic dataset, business logic and behavior
  • 21. The Map • A set of geometric features that represents a geographic reality. • A ‘window’ for exploring the data.
  • 22. The Model • Analysis tools that creates new geographic information from existing data.
  • 23. In short, a GIS is… An information system (hardware, software, data) which enables us to apply lots of analysis models to any geographical datasets for generating derived information that can be visualized as maps. “ A Geographic Information System helps us understand our world, answer questions about our environment and support us during decision-making.

  • 31. Data Layers Topologic integration Fire risk Data
  • 32. Topology • Branch of mathematics that studies geometry from a qualitative perspective. • Topology describes the geometric relationships of a given space. “ A topologist is someone that can’t distinguish between a cup of coffe and a doughnut Data
  • 33. Topology in our GIS • Defines the way different point, line or polygon layers relate each other geometrically. Two contour lines can’t intersect Two parcels can’t overlap Buildings must be within parcels Data
  • 34. Behavior in our GIS • Geometric features may have properties that represent geographic objects. Street network (edges, junctions, turns, impedances) Cadaster (parcels, boundaries, nodes ) Data
