8 Geographic Information System

9 Geographic Information System with a spatial component for capturing, managing, analyzing and understanding information A set of software, hardware and data

10 Geographic Information System A GIS integrates hardware, software and data to capture, manage, with a spatial component for capturing, managing, analyzing and understanding information analyze and visualize any kind of information with a geographic component. A set of software, hardware and data

11 «You do not really understand something unless you can explain it to your grandmother.» Albert Einstein Theoretical Physicist, unfortunately not related to GIS

12 Everyone as a part of a GIS

18 A few practical applications

19 GIS modelling our world Restaurants Hotels Streets Roads Rivers Parcels Vegetation Water bodies Elevation Imagery Reality

20 Conceptual workflow Data Geometry Rules Parcel No. Type Address C López de Hoyos C Antonio Salces A América P Prosperidad C Luis Cabrera C Santa Hortensia

21 Three perspectives Map Data Models

22 The Data A single data repository: the Geodatabase Every geographic dataset, business logic and behavior

23 The Map A set of geometric features that represents a geographic reality. A window for exploring the data.

24 The Model Analysis tools that creates new geographic information from existing data.

25 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.

28 Geodatabase Centralized data repository Spatial relationships Multi-user access Vectors Networks Survey Addresses Annotation Versioning Security Scalability 3D Objects Topology Attibutes Dimensions Terrain Parcels Geodatabase Symbology Imagery CAD Data

29 Data Layers Streets Data

30 Data Layers Parcels / Building footprints Data

31 Data Layers Water pipes Data

32 Data Layers Hydrants Data

33 Data Layers Topologic integration Fire risk Data

34 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

35 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

36 Behavior in our GIS Geometric features may have properties that represent geographic objects. Street network (edges, junctions, turns, impedances) Cadaster (parcels, boundaries, nodes ) Data

51 A GIS is An information system (hardware, software, data) that allows us to apply lots of analysis models to any set of geographic data in order to generate derived information that can be explored as a map.

52 Geographic Information Systems help us understand reality answer questions about our world and support us during decission-making.
