  2. Applications: Introduction Task 1: Introduction to Arc Catalog Task 2: Introduction to Arc Map Challenge Question References

  3. Figure 1.1 An example of geographically referenced data. The street network is based on a plane coordinate system. The box on the right lists the x- and y-coordinates of the end points and other attributes of a street segment

  4. Figure 1.2 The vector data model uses x-, y-coordinates to represent point features (a), and the raster data model uses cells in a grid to represent point features (b).

  5. Figure 1.3 When we use the add data button to add a layer to a map, we are actually using the Add Layer method on the IMap interface that the Map class supports.

  6. Figure 1.4 A classification of data formats used in ESRI software by topology and data model.

  7. Figure 1.5 An example of the TIN model.

  8. Figure 1.6 An example of the regions model. Two regions, one for burned areas in 1919 and the other in 1929, overlap each other in some areas. Each region is also comprised of spatially disjoint parts.

  9. Figure 1.7 An example of the dynamic segmentation model. Rest areas are plotted as point features on highway routes in Washington State.

  10. Figure 1.8 A classification of GIS operations.

  11. Figure 1.9 A vector-based overlay operation combines spatial data and attribute data from different layers to create the output.

  12. Figure 1.10 A raster data operation with multiple rasters can take advantage of the fixed cell locations.
