GIS4102 Lab 6

-
This was a challenging lab for me. I started this course as a total newbie to Python, and feel like I've gotten to a point where I have pulled off some challenging tasks in this 6 week course. Here we had to take a shapefile of rivers in Hawaii, and use a search cursor with for loops to extract 6 features: object ID, X and Y coordinate data, Name, geometry object, and a vertex ID that we generated, and print them to a text file and our console. Here is the flowchart for this process:
The first steps are to import the relevant modules, set the environment,and turn on overwriting. There are apparently two ways to handle setting up the text file, either creating it beforehand with write mode turned on, or allowing the program to create it. I created it beforehand. I encountered a problem initially because I didn't have the name exactly matching in my code, which I think may have been a non-issue if I'd allowed Python to create it. Then we created a search cursor to extract the relevant info from the attributes of the rivers.shp file, and nested for loops to extract each relevant feature from the rivers.shp attributes, write them to a txt file in rows, and print to our console. The final .txt output is here:

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.

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...
