Intro to ERDAS Imagine & Digital Data

This week's lab introduced us to ERDAS Imagine, a raster-based software used to extract information from aerial imagery. We learned the basics of adding layers, examining metadata for each layer, creating subset images, and exporting images to be further manipulated in ArcGIS Pro. 

The map below shows the land cover of an area within Olympic National Park. This area is a subset of a larger Landsat Thematic Mapper (TM) image that was resampled to 30m and had the thermal band removed. This image was pre-processed using ERDAS Imagine and was exported to ArcGIS Pro to create the final map output. Each color on the map represents a different land cover class, and the total acreage represented by each cover class is provided in the legend.
