Module 5: Explore & Manipulate Data

This week's assignment focused on automating geoprocessing tasks. The goal was to write a script that created a new file geodatabase, copied all shapefiles from a data folder into it, and then searched for a New Mexico "county seat" cities to build a dictionary of city names and populations.

The script walked through a series of tasks:
Set the workspace and import modules; Created a file geodatabase in a Results folder using the student account name; Listed all feature classes in the Data folder; Copied those shapefiles into the new geodatabase; Used a Search Cursor to pull out the fields needed; Built a dictionary mapping city names to population values; Printed the final dictionary, displaying all the results.

The hardest part for me was step 4: Copying feature classes into the geodatabase. While copying shapefiles to the new geodatabase, I wasn’t initially getting the elapsed time message for each shapefile. This was because I was calling the function outside the loop. To fix this, I moved the line of code inside the loop. This allowed me to print the correct elapsed time for each copied feature.

It was satisfying to see the script run from start to finish, producing a clean dictionary of the cities and their population. Even though I hit a few bumps along the was, figuring out the issue made me feel more confident in handling ArcPy scripting logic.

This week was a good intro to the program and a good start to getting used to how the system works. It will just take more practice to get used to where things are and what they do.

Module 5: Data Points and Geocoding

  Manatee County Schools - Overview      Here is the Link to my map for this week.      The map this week is the locations of all the schools located in Manatee County, Florida. It contains information such as the coordinates, addresses, and names of the schools. Schools of all grade type are on the map. I.E elementary through college.         This weeks experience was different because we got to use Excel and partially collecting our own data from different sites. This week felt a little easier, because I have experience with Excel and I enjoy getting to use it for new things. It was nice having the labs feel a little shorter, but still learning just as much. It was easier to manage, and understand, without the potential to feel overwhelming, which I enjoyed. I didn't run into any issues in these labs, everything ran smooth.

Module 6: Georeferencing, Editing, & 3D.

Image
  This map is a georeference of three different raster images of the UWF Campus in Pensacola, Florida. The map also includes the location of a Bald Eagle nest that was found by the FWC, and the subsequent easement that was created around the nest to protect it from harm. This week's experience was pretty fun! I really enjoyed georeferencing. Matching the older pictures of the campus with the modern day map was a cool experience. Setting up control points on the map was pretty straight forward, and I felt pretty confident following the steps and indicators. I found editing the map features interesting because it was a way to add more information to show certain characteristics that need to be highlighted. Working on the 3D map was fun because it showed me a more realistic view of what the area actually looks like, which I enjoy more than the generalized maps that we have looked at previously. The following map is a georeferenced of the UWF Campus as well, on 3D scene:
