  2. 1.5 Organization of This Book 1.6 Concepts and Practice

  3. Applications: Introduction Task 1: Introduction to ArcCatalog, ArcMap, and ArcToolbox Task 2: Introduction to ArcInfo Workstation

  4. An example of geographically referenced data. The street network on the left is based on a plane coordinate system. The box on the right describes a street segment in terms of the x- and y-coordinates of its end points and the attributes.

  5. (col 2, row 2) (x1, y1) (x3, y3) (col 5, row 5) (x2, y2) (col 1, row7) The vector data model uses x-, y-coordinates to represent point features on the left, and the raster data model uses cells in a grid to represent point features on the right.

  6. Spatial Data Vector Data Raster Data Non-topological Topological Higher-level Data Simple Data Dynamic Segmentation Regions TIN Data models for spatial data

  7. A classification of GIS activities

  8. Vector-based map overlay combines spatial data and attribute data from different maps to create the output.

  9. Raster data analysis with multiple grids can take advantage of the fixed cell locations. Geometric intersection is not an issue with raster data.
