 Lab 3 Intro to ERDAS Imagine and Digital Data Lab

This week se stepped outside of the ArcGIS Pro box for a moment and were introduces to ERDAS Imagine.  This is a remote sensing software with a wide range of tools for imagery and geospatial analysis. We opened a provided image into an ERDAS Imagine viewer and explored the basics for zooming, adding, images, preferences and various settings. We altered the bands to a TM False Natural Color band combination and explored the difference with other color settings. Next, we learned how to open the attribute table in ERDAS and add a field.  For our purposes it was a new area field which we would use once we opened the image in an ArcGIS map project. We used the Inquire Box tool in ERDAS to select one section of the image to focus on. In our map project we added the image we worked with in ERDAS and changed the symbology. We were then asked to created a map layout highlighting land cover types and the total area of each one.  Below is my map layout:

It was nice to be introduced to software outside of ArcGIS. ERDAS Imagine has a wide range of capabilities and we barely scratched the surface. I didn't find it as user friendly as ArcGIS Pro but I'm sure that is a novice reaction.  

Part b of our lab involved further examination into some additional ERDAS tools and functions. We touched on the four different types of resolution in ERDAS, and analyzing, and interpreting thematic rasters. No new map layout was required for this section.
