Module 4 and Quiz 4 Study Guide
THIS MATERIAL IS IMPORTANT AND YOU MUST KNOW HOW TO CREATE GDBs
AND GET DATA INTO THEM! -- Note; THIS QUIZ WILL BE LONGER THAN NORMAL
AND WILL COUNT FOR MORE THAN THE NORMAL QUIZ!
The important sections of Mod 4 are:
1 Exploring Geographic Data
o The GeoDatabase
o Coverages are older data structures – just scan
o Shapefiles – read o Raster data formats – read
o Images – read
o Skip the exercise unless you want more info on these subjects
2 Organizing data into a GeoDatabase - This section is important and the class
quiz will focus on
o The types of GeoDatabases and what they are good for
o Designing the GeoDatabase – scan, is probably overkill for what you
would likely be doing.
o Getting data into a GeoDatabase. – VERY IMPORTANT!
When do you copy and how do you do it
When do you load and how do you do it
When do you import and how do you do it
o Understanding Field Types – know them!
3 DO THE CREATE A GDB EXERCISE
4 Read section 2.2.1.2 (pg41), Scan section 2.2.2
Sample Questions for the quiz
1. In a GDB all features not in a Feature dataset (FDS) must have the same
geometry and spatial reference (T/F)
2. A FC can be built from multiple features if they all have the same geometry.
(F/f)
3. The three forms of GDBs are?
4. Of the file and personal GDBs, which can hold the most data? How much?
5. GDBs can be created in either Map or Catalog? (T?F)
6. When you create a GDB you must specify the maximum extent of the data you
plan to insert into it. (T/F)
7. When a FC is created from multiple files you can control the contents of the
combined attribute table. (T/F)
8. What is topology?
9. What are the three ways to get data into a GDB?
10. What is an object data in the jargon of GDBs?
11. What types of feature and object data can be brought into a GDB? List at
least 5.
12. Are there any limitations on which of the ways can be used for the different
types of feature or object data? If so, what are they?
13. Outline the process of creating a GDB.
14. Outline one process of adding feature data to the GDB
15. Outline the process for creating a FDS
16. Define GDB, FDS, and FC
17. The quiz will include a list of features which must be added to a GDB. You
will have to design the GDB as to what layers would be put into the GDB as
features, which should be added to a FC, and which should be added to
FCS(s). It will not be complex but you will have to think about it!
