GIS Image Analysis in ArcGIS Pro

University of Alaska Fairbanks via edX

Overview

Image analysis is the extraction of meaningful information from an image to accomplish a simple task like understanding the landscape or to solve a complex problem like face recognition.

This course is focused on image analysis and applications in the area of natural resource management, geography, geology, and environmental studies. Participants will use a variety of remotely sensed data including high resolution aerial photo, Landsat and Terra MODIS satellite data to solve specific problems.

Learners in this course will learn fundamentals of remote sensing, image processing and image analysis. Learn image analysis in Esri ArcGIS Pro through hands-on exercises including image display, image interpretation, change detection using spectral indices, supervised and unsupervised image classification for land cover mapping, and effect of arctic warming on vegetation productivity.

The course features lessons covering GIS image analysis applications on real-world problems.

Verified track learners will receive an ArcGIS Pro license in addition to unlimited course access and a verified certificate.
