Module 10 - Week 12

INTRODUCTION:

This week we will continue discussing and learning about GIS-based spatial analysis. Recall that analysis such as this represents the true power of GIS, that is, GIS is capable of much more than just creating maps. Last week we learned about basic spatial analysis through data selections, or queries. We will continue learning how to do queries this week, but also learn about advanced spatial analysis, more commonly referred to in the GIS world as Geoprocessing. Through Geoprocessing, we manipulate datasets to asked advanced spatial questions and identify spatial relationships. Much of this leads to the creation of new datasets.

LEARNING OBJECTIVES:
  • What is Geoprocessing
  • What does Geoprocessing mean for GIS
  • How does Geoprocessing differ from selection or query analysis
  • Understand how Geoprocessing leads to the creation of new datasets
  • What is ArcToolbox
  • What are some things to consider when using ArcToolbox
  • Understand the difference between raster and vector tools
  • What is advanced Geoprocessing
SOFTWARE OBJECTIVES:
  • Become more familiar with data selections and queries
  • Understand the difference between attribute and spatial queries
  • Be able to analyze selected (queried) data
  • Be able to export selected features as new shapefiles
  • Become familiar with ArcToolbox
  • Be able to perform basic Geoprocessing tasks using ArcToolbox
READING ASSIGNMENTS:
CLASS MATERIALS:
SUPPLEMENTAL RESOURCES:

LAB MATERIALS:
  • Lab Assignment 5 data will be on our class server or from here.
  • Information on final projects will be discussed on Wednesday, March 30th.
HOMEWORK ASSIGNMENT:
  • Lab Assignment 5 is due by the end of the day on Friday, April 1st.
LOOKING AHEAD:

Next week you will be working on the first part of your final projects. The final project is meant to test all of the skills and knowledge you have acquired through the semester, with specific focus on analysis and mapping.

Module 9 - Week 11

INTRODUCTION:

This week we will continue the discussion of "data", and we will continue working with "raw" data in GIS; entering raw data into GIS, editing it, manipulating it, and outputting it. Specifically we will continue with the tornado mapping exercise, as well as some other "raw" data exercises. In addition, we will begin the discussion of "Basic GIS Analysis". After all, it is this "spatial" analysis that represents the true power of GIS. We will learn how to ask "spatial questions" of our data through data selections and queries in ArcMap.

LEARNING OBJECTIVES:
  • Understand difference between spatial and attribute data edits
  • What is GIS Analysis?
  • What are GIS-based queries?
  • What are GIS-based selections?

Module 8 - Week 10

INTRODUCTION:

This week we will discuss the long eluded to, much anticipated, subject of coordinate systems and map projections, collectively referred to as "spatial reference information". For a variety of reasons I have waited till the mid-point of the semester to introduce this topic, but that should by no means take away from its importance to the study of GIS. In fact, without spatial reference information, there would not be GIS. GIS is all about layering information to assess patterns and relationships, among other things. But it is the individual layer's "spatial reference information" that allows it to be overlaid correctly with other layers. Most of this is handled automatically and behind the scenes in ArcMap, but there are still some important things about the subject that you should be familiar with.

LEARNING OBJECTIVES:
  • What is spatial reference information?
  • Why is it so important for GIS data?
  • Understand the two main type of coordinate systems
  • Understand latitude and longitude coordinates
  • What is Geodesy?
  • What are datums?
  • Understand map projections
  • Understand difference between map projections and ESRI's use of the term "Projections"
  • Be aware of three types of map projections
  • What is map distortion?
  • What are some common map projections?
  • Terminology: Coordinates, Projections, Projected Coordinates, Geographic Coordinates - Spatial Reference Information
  • What does data mean to GIS?
  • Understand each of the various data tasks associated with GIS
  • What are the three main types of original spatial data collection?
  • Be familiar with some common GIS data sources
SOFTWARE OBJECTIVES:
  • Be able to examine spatial reference information of a layer in ArcMap
  • Understand how the data frame's coordinates are set
  • Be able to adjust coordinates of the data frame properties
  • Understand how to use the Define Projection Tool and the Project Tool
  • Understand the difference in these two tools
  • Be able to define a layer's coordinate information
  • Be able to convert a layer's coordinate information to a different system
  • Be able to plot x/y data in ArcMap
  • Be able to create (digitize) basic data in ArcMap

Module 7 - Week 8

This week we will continue working with symbology and with creating maps in ArcMap. Specifically, we will recreate an event map from the 2009 snow event that the Greenville-Spartanburg NWS office has on their website.


Once we have recreated the original map, we will create some alternative versions to it, experimenting with different class ranges and colors, and additional data layers. We will also add appropriate map elements to the map to make it truly a map product.

Homework Assignment:

Lab Assignment 4 is due prior to class on Wednesday. Essentially, you will peruse the data holdings in the Mater Data folder, within the Instructor Folder on the File1 Server, and create a map with at least 3 layers, being sure to include the appropriate map elements.

Test 1:

As previously stated, Test 1 will be a take-home exam. It will be distributed in class on Wednesday, March 2nd, and due to me at or before the beginning of class on Monday, March 14th. The test will include a lab component.

Accessing the File 1 Server

In addition to following the steps to the right for the Class Network Drive, remember that we now need to always either restart or log-off and log back in to the computers each week when we come to class, the follow the steps for Class Network Drive. Then at the end of class, you will want to log-off. This is true for any other lab you may visit on campus.
