  2. Today’s Objectives • explore a map and get information about map features • preview geographic data and metadata • add data to a map • describe the structure of a map • explain how a GIS represents real-world objects • change the way features are drawn on a map • access feature information in different ways • describe spatial relationships of map features • describe how GIS can be used to solve problems

  25. Localized Information

  26. Spatial Relationships 1 • Distance Which countries contain a lake completely within their borders? Which cities are located within 25 kilometers of a river?

  27. Spatial Relationships 2 • Intersection Which countries have a river that intersects their border?

  28. Spatial Relationships 3 • Adjacency Which countries share a border with Russia?

  29. Spatial Relationships 4 • Containment Which countries contain a lake completely within their borders?

  30. GIS as a Process 1 • Capture data • Store data • Query data • Analyze data • Display data • Present data

  31. GIS as a Process 2 • Ask a geographic question • Acquire geographic data • Explore geographic data • Analyze geographic information • Act on geographic knowledge

  32. Summary • A GIS organizes and stores information about the world as a collection of thematic layers. Each layer contains features with the same shape and attributes, all located within a common geographic area. • Each feature is assigned a unique numerical identifier and is characterized by a unique location in space and a corresponding record in a table. • Features can be stored in a GIS as three primary shapes: points, lines, or polygons. • Features have spatial relationships with other features, and with a GIS you can find features based on their spatial relationships. • The geographic inquiry process provides a framework for solving problems with GIS.
