ArcGIS Desktop III: GIS Workflows &
Analysis
Overview
The ArcGIS 9.2 version of this course was titled Introduction to ArcGIS II.
Understanding how and when to apply ArcGIS tools and functions is the key to creating an
efficient GIS workflow. Building on the skills and knowledge taught in ArcGIS Desktop II: Tools
and Functionality, this course shows how to apply ArcGIS tools in a workflow context with a
focus on working with data stored in a geodatabase and performing geoprocessing and analysis.
In the course exercises, you organize and edit data stored in a geodatabase, prepare data for
analysis, create and edit geoprocessing models using ModelBuilder, and work through a
challenging analysis project.
Topics Covered
Getting data into the geodatabase: Advantages of migrating data to the geodatabase; File
and personal geodatabases; Loading and importing data; Data sources available for
conversion; ArcToolbox conversion tools; Importing and exporting data in ArcCatalog;
Importing and exporting data using XML; Copying and pasting data between
geodatabases; Batch and single conversions; Loading data into existing feature classes
using the Simple Data Loader; Displaying x,y coordinate data from a table; Accessing
tabular data using an OLE DB connection; Adding data from a GIS server; Working with
map projections and datums.
Geodatabase behavior: What is behavior?; Advantages of using behaviors; Default values;
Subtypes; Domains; Geodatabase topology.
Editing GIS data: Creating new data (digitizing, copying and pasting features, Editor menu
commands); Constructing an edit sketch using constraints (direction, length, parallel);
Creating adjacent polygons using the Auto-Complete Polygon task; Modifying existing
features; Reshaping existing features and boundaries; Exploding multipart features;
Editing using domains, subtypes, and topology.
Alligning spatial data: Common data alignment problems; Georeferencing CAD data;
Matching layer boundaries; Transformation; Rubber sheeting; RMS error.
Managing geoprocessing tools and settings: Types of toolboxes and how they are stored;
Types of tools (system tools, models, scripts); Locating tools in ArcToolbox; Executing tools; Tool
parameters; Parameter error detection; Environment settings; Tool layers; Geoprocessing
results.
Analyzing GIS data: Review of common analysis tools (Buffer, Clip, Intersect, Select,
Union); Working with feature proximity tools (Near, Spatial Join, Multiple Ring Buffer,
Create Thiessen Polygons); Analyzing tabular data; Creating a raster subset; Analysis
options outside of core ArcGIS Desktop; Typical analysis workflow.
Using ModelBuilder for analysis: Working with ModelBuilder; Creating and designing
models; Model elements (tools and variables); Setting general model properties; Setting
model parameters; Environment settings; Intermediate data; Running and troubleshooting
a model; Creating model documentation.
NEW
GIS analysis projects: Real-world GIS analysis projects (Find the best site for a new
shelter, Find the mileage of flooded roads); the analytical process for each project.
