GIS 4006 M7 Lab: Google Earth Pro

-
This was a fun lab -- we got to use Google Earth Pro for the first time, and practice creating layers in ArcGIS Pro and converting them to KMZ layers and exporting to Google Earth. Here, I've symbolized water features, overlain a dot density population map, and added a JPEG of a legend. Part of our deliverables, not shareable here, was making a tour in Google Earth Pro. In this screenshot, you can see the places it covered. This is a neat feature where you can link places in sequence and have an audio accompaniment. I had an extremely difficult time with technical issues here -- for some reason my first few attempts at exporting the surface water layer to Pro resulted in multiple features symbolizing as black at 0% opacity. Since there are scores of rows in each feature, it was too onerous to fix manually in the time I had left. Also, when I was manually adjusting symbolization using hex codes, the preview was the right tint, but the actual output was far too dark. Apparently these are both known issues with Pro and ArcGIS, and ultimately my solution was to start over in the middle.

GIS 4006 Computer Cartography Intro Post

Hello everyone, After taking one class off, I'm on my second class of the GIS certificate program at the University of West Florida. I got interested in GIS after going to a regional GIS conference a couple of years ago, and I've been trying to learn everything I can along the way. I'd like to move into a GIS career after finishing this program. Our first assignment was a StoryMap, and I built one showing places I've lived. Thanks for looking! https://arcg.is/0mS1eD

GIS4035 Lab 2, Land Use/Land Cover

This was not a particularly hard lab, but the main challenge was time management. We were given an aerial photo of Pascagoula, MS and had to classify the entirety of it to level II land use/cover categorizations. This took a lot of inferences and assumptions - we were discouraged from using other sources in the initial part, then checked our accuracy with Google Street View. I actually had a fairly high accuracy.

GIS 4035, Lab 4: Spatial Enhancement and Multispectral Analysis

This was one of the more interesting labs that we have done. The first part was primarily concerned with fundamental skills in ERDAS Imagine, like using the chip image and subset tool, opening histograms, using the enquire cursor, and exporting data for use in ArcGIS Pro. We also accessed public domain US satellite data to analyze in Imagine. In the later part of the lab, we identified features according to criteria on the lab guide, such as features that caused a spike in pixels in a certain range of brightness in specific EMF bands, and had to use visual analysis and the enquire tools in Imagine to find them. Then, we created maps with combinations of RGB colors in different bands to show off which feature met the criteria. This was interesting, in part, because we had to think about color theory a little bit and why something bright in certain bands, when assigned colors in those bands, would produce the map effects that we got (i.e. if we assigned blue and green to bands where...
