Some Things to Study for Quiz #3

1.     Know what the components of vector data are (below) and how they are different from each other.  That is, if given a sketch of a line showing each of these components, be able to identify each:

  • Edge

  • Vertex

  • Segment

  • Endpoint

  • Line

2.    Given the list of operations (below) that would need to be executed in order to create a new polygon shapefile with new features using an existing point shapefile as reference data,
        be able to number the list of operations in order as they would be executed.  (Note:  It is a good idea to practice this in advance using ArcMap to insure that you have the right order).

  • Digitize (draw features)

  • Create and or define "Workspace"

  • Click on "Stop Editing"

  • Click on "Start Editing"

  • Display new shapefile along with the reference "point" shapefile

  • Create new shapefile

  • Open the Editor Toolbar

  • Open ArcMap

  • Save Edits

  • Open ArcCatalog

3.    What is georeferencing?

4.    Know what the input (before processing) data and output (after processing) data would look like after using the geoprocessing tools below.  That is, be able to identify from a visual illustration of the before and after of each of these tools, which tool it is:

  • feature to polygon

  • feature to line

  • feature to point

  • clip

  • union

  • buffer

  • identify (aka, identity)

  • dissolve

  • intersect

  • append

  • overlay

  • extract

5.    What is symbolization?  Provide a few examples of how it could be used to allow for two or more layers to be displayed and visible simultaneously in ArcMap.

6.    What are the four standard classification methods that could be used to classify data and how do each of them work in dividing up the data into different categories?

7.    What are some limitations of traditional paper maps?
