Working with Geodatabases and Linear Referencing

A Juniper GIS class

GDBAccess.jpgThis E-Learning course was developed by John Schaeffer, and is designed to teach students all the fundamentals of the Geodatabase; creating and managing the geodatabase, using domains, subtypes and topology to better manage your data, using images with the geodatabase, and using specialized editing tools to correct and clean data, and creating routes.

Students will learn how to use Geodatabases by working through two realistic projects. The first project is preparing data for a burn plan on the Florida Panther Refuge; the second is working with stream data from the Wenatchee National Forest to analyze fish populations.

Intended Audience

This course assumes you are comfortable with using ArcGIS 10 for general GIS tasks and that you have had some editing experience. The course is written for ArcGIS 10, but will work with 9.3.1, though the dialog boxes might be slightly different.

Course Outline

streams_hatches.jpgThe course is divided into three sections.

In the first section we will look at the basics of creating and managing a Geodatabase, and then converting data to the geodatabase format.

The second section will show you how to use the geodatabase to validate or check you data for attribute and spatial errors, how to make data entry easier, and how to edit with Geodatabase Topology.

In the third section, we will work with Routes and Linear Referencing. Routes let you attach multiple data tables to linear features for analysis and mapping. The easiest way to think about routes is the milepost numbers you see as you drive down roads. Once you have established a route with "mileposts" you can then link this to multiple data sources. In the last module, we'll show you a sample extension that will make it easier to manage and create reports on your geodatabase.
