Working with Imagery in ArcGIS 10: Easier, Faster, Better

The recording of the Visualizing and Analyzing Imagery with ArcGIS 10 training seminar is available on the Esri Training website. This free, one-hour seminar covers the desktop capabilities for dynamically enhancing image display and performing on-the-fly image processing.

At ArcGIS 10.x for Desktop, the Image Analysis window in ArcMap gives you direct, one-click access to a collection of commonly used image display and processing tools. These tools are available at all license levels—Basic, Standard, and Advanced. In the seminar, Esri instructor Michael Rhoades shows how these tools make image interpretation and analysis workflows easier and faster. The last part of the seminar covers image classification tools included with the ArcGIS Spatial Analyst extension.

Dynamically process imagery using ArcGIS 10

In this demo, one of six demos given during the seminar, you’ll see Michael sharpen an image to immediately improve visualization and apply the NDVI function, which is often used to analyze vegetation cover.




Other options to learn about imagery workflows in ArcGIS 10.x include:

Mapping Time in ArcGIS 10

One of the features of ArcGIS 10.x is the ability to “time-enable” your data in ArcMap. Visualizing how data changes over time provides opportunities for powerful, more in-depth analysis. If you’re using ArcGIS 9.3, you can visualize temporal change by creating an animation. You can still create animations at version 10, but there’s an easy alternative as well.

The example below shows how to visualize piracy-related incidents that occurred between March, 2007 and February, 2009 in and around the Gulf of Aden. Continue reading
