ArcGIS Desktop III: GIS Workflow and Analysis
OVERVIEW
Understanding how and when to apply ArcGIS tools is the key to creating an efficient workflow that supports GIS analysis. This course teaches how to apply ArcGIS tools with a focus on working with data stored in a geodatabase. Trainee will organize and prepare data for analysis, create geoprocessing models, and work through a challenging analysis project. The workflow taught in this course is applicable to all types of GIS analysis.
TARGET GROUP
This course is designed for GIS analysts, GIS specialists, and other experienced ArcGIS users.
GOALS
After completing this course, trainee will be able to
- Add data from different sources to a geodatabase.
- Create and edit geodatabase features.
- Work with geodatabase tools that ensure data integrity during editing.
- Solve common spatial data alignment problems.
- Use a variety of geoprocessing tools to perform analysis.
- Build a complex model to automate an analysis workflow.
TRAINING DURATION
2-3 days (negotiable)
TOPICS COVERED
- The geodatabase: Advantages of migrating data to the geodatabase; File and personal geodatabases; Loading and importing data; 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; Exploding multipart features; Editing using domains, subtypes, and topology.
- Aligning 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: Creating and designing models; Setting general model properties; Setting model parameters; Environment settings; Intermediate data; Running and troubleshooting a model; Creating model documentation.
- 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.
