Week 3: Data Collection and Projections

 

This week I learned about map projections and how they affect mapmaking. Due to the curvature of the Earth, it is impossible to show a 100% accurate reading of the Earth's surface in a flat format. Therefore, every map projection differs slightly in some way, and it is important to compare them for the most accuracy. I made this map depicting a comparison between three different map projections of the area of Florida counties. Observe the difference in area recorded between the Albers, UTM Zone 16, and Florida State Plane North projections. 

In addition, I got familiar with ArcGIS Online and using a mobile device to collect data in the field. I collected data regarding the condition of all of the stop signs in my neighborhood, and uploaded into a map in ArcGIS Pro. Due to the catastrophic hurricane that affected the area in 2018, most signs were replaced relatively recently and were in very good condition. I also learned that people give you strange looks when you go around taking pictures of every stop sign in the neighborhood. Going out in the field and collecting my own data was a very enjoyable experience, and inputting data I collected into my map was extra satisfying. I hope to find a career within GIS that offers a balance of field work and desk work.

GIS Programming Week 3

       This week I learned the basics of fixing errors within your Python script, a process called debugging. I was provided with a few scripts that contained several errors, and it was up to me to address the issues and make the script functional.  To find the problems in the code to debug them, I first ran the script to see what errors occurred. The error messages in the Python Shell were quite helpful as they told me what type of error it was, as well as the specific line it came from. Most of the troubles were simple spelling or syntax errors, which were easy to fix and help further familiarize me with the proper grammar of Python. I found the entire process quite enjoyable and rewarding. Below is the final output of the first two scripts I fixed, which retrieved shapefile information from a project in ArcGIS pro.      For the final script, I was told to not fix any errors found, but to instead employ a "try/except block", a tool used to work ...

Cartography Week 5: Choropleth and Proportional Symbol Mapping

Image
  This week I created a choropleth map based on the principles I've learned. A choropleth map is a thematic map that uses color mapping symbology to represent data. You have likely seen one of these in the form of an election map. The choropleth map above uses proportional symbolling, symbols that scale with the data, to depict wine consumption in Europe in 2012 compared to the population density in each country.

GIS Programming Week 5

This week I learned about manipulating spatial data within Python. I used what I learned to create a script that creates a new geodatabase, copies shapefile data to that new database, and creates a Search Cursor and dictionary to isolate and print County Seat cities in New Mexico and their respective population circa 2000. I found the first few steps of the lab straightforward, but first ran into trouble when creating the Search Cursor. At first, the output printed on the same line and looked very messy. To fix this, I ended each line by inserting an escape character <\n> to the script, which fixed that issue. I had the most trouble populating the empty dictionary. The output initially only gave me the last key in the dictionary, but I realized this was because the line of code creating the empty dictionary was blocking the for loop, so I moved it up a few lines and was able retrieve the whole dictionary successfully. I also ran into trouble while trying to place all of my print ...
