At the beginning of the term, I had no clue what Python was. I made an effort to understand it by asking my friend, who is majoring in computer science, and my partner who had worked with python previously, about it. I clearly had made a mistake as by the end of the conversation the two went off on their own tangent about python and I became totally lost in the conversation and came out with no further understanding of what it was.

By the time we came to discussing it in class, I knew one thing about python, that it was a programming language, which still meant absolutely nothing to me. Going down to the computer lab I was very unsure of what exactly it was I was doing and reading the lessons felt as if my friend and partner were talking about it to me all over again, which meant I still had no clue what I was doing or why. I was constantly re-reading instructions and concepts to try to understand them but was never quite successful in actually understanding what I was doing.

I started with lesson 2 and followed the instructions closely, I typed in the HTML for the “Hello World” section but continuously had an error message occur, which informed me that there were issues with the syntax. I went back and made sure everything matched up correctly and still ran into the same issue. I then decided to copy and paste the example into the program to see if I could remedy the situation and I still ran into the same error. I cleared my program and re-tried typing the code in manually to see if I could get it to work and still ran into the same problems. I was shortly informed that the triangles around

<!— Hello World — > were in fact not supposed to be there. After deleting those and then going through other issues I had with saving the document as HTML and deleting the initial >>>print ‘hello world’ off the file I continued on to lesson 3.

I don’t remember really having any sorts of issues with lesson 3, as I don’t have much written about it in my notebook. Lesson 4 for functions made some sense to me and I was able to continue on without much of a hitch. Then it came to modularity which is when I became confused as I really didn’t understand what I was doing and started to somewhat internalize the fact that I may not be doing this right and that I didn’t understand. I had the continuous feeling as if I was treading water with nowhere to go and just felt stuck.

I was offered help in this section but I was still really just stuck in my own head and intent on figuring this out myself so I declined the offer of help. With 5 minutes left in the lab, I just decided to go for it and follow the example of the lesson and it worked at least to the best of my understanding, it worked.

After discussing what a programming language was in class I came to the lab feeling much more confident with a better understanding of what I was doing. I ran into issues again with lesson 6, downloading web pages. I followed the example to the letter and was continuously incorrect.

I copied and pasted it to see if I couldn’t get it to work, but it didn’t. After we were told to try this exercise with Active History, I tried once more with the Old Bailey…I really wish I had written down what I did because I got it to work. I genuinely have no clue what I did…at least I assumed I had gotten it to work because I didn’t get an error message, so I found it to be a success.

 

The last lesson I was able to fully complete was lesson 7, Manipulating Strings. I had a few minor issues with syntax again, but I was able to correct those mistakes fairly quickly. At this point, I was actually starting to feel kind of proud of myself, as I have never worked with this type of program before and felt as if I actually understood what I was working with and what the end product should be.

Although half of the time I had no clue what I was doing, I am ultimately glad to have to opportunity to explore this tool. To actually be able to understand it and what purpose programming languages have, as this is a concept I was very unfamiliar with prior to this class.

I’ll have to be honest, the concept of HGIS was a relatively foreign topic to me before December 2018. I had a good understanding of what HGIS was when this term started but had never had the opportunity to use it until these last few classes. I actually felt fairly confident on what I was doing when first launching the program. Being not very technologically savvy it did take me a few moments before I was informed I had to unzip the file before placing the datasets into the program. After I got around that I had no problems continuing on for a while before we had to export data. When I exported the new map file I tried to move on to the next stage with symbolizing attributed data. I ran into issues during layering properties, in the fields section while trying to change the number of classes to 4. Whenever I tried to change the number to 4 it would automatically change back to 1 and would not allow me to change the break values. After several minutes of being frustrated and wondering why I couldn’t get this section to work, I eventually had to get help. I was informed that I had exported data to the map incorrectly, I didn’t export all features. Once I was informed of my mistake I continued on as I had tried to earlier and was actually successful from there.

By the time I ended with Lesson 1, I was still not fully confident that I had done it correctly but continued on even so. By the last 3 minutes of class, I was more concerned with actually finishing the map and getting to an end result. In terms of labelling by the end, I cut a few corners as once again I really wanted to finish this lesson before the lab ended.

My start with lesson 3 was much more positive, I didn’t find it nearly as daunting as I felt with lesson 1. It also took me less time to start the program because I actually remembered to unzip the file before trying to put it into the program. The one place I had to stop to think was adding control points, as I wasn’t sure if I should click the wind erosion map first or the outline. After a few moments, I finally decided to click on something and figure out how it worked. I initially clicked the outline to the erosion map and realized I didn’t do it correctly and accidentally deleted the entire erosion map and had to re-do the entire thing. I went back through the process and re-started the process with the wind erosion map. I was surprised by how much I remembered American geography when having to add a control point at the northwest corner in Montana. From there I had no problems with the control points of the southwest corner of New Mexico, the northwest corner of North Dakota, and the northeast corner of Texas.

To be honest, I really didn’t understand the mathematical conversion as I really struggled with math throughout my entire life so I continued through the rest of the steps, ignoring the numbers. With the three other control points, I added ones at the southeast corner of Texas, on the border of North Dakota and South Dakota, and the north-west corner of Wyoming.

I looked back to the residual values in the link table and ended up deleting all of the ones I had placed as they had the highest offset in the table. I believe I ended the process with geo-referencing there and continued on playing with ArcGIS online for the last 20 minutes of the lab.

For about 5 minutes I explored the option of adding map notes, using the city as an example and placing pins in the map randomly. I then started adding different map layers to the map, I looked at American Indian Reservations/Federally Recognized Tribal Entities and then added Proclaimed Forest Boundaries.

-The dark blue portions represent the federally recognized reserve and land, the lighter green colour represents forest boundaries.

I explored the different options on the map with style and colour changes. I unselected the Proclaimed forest boundary to focus on exploring ArcGIS with the federal reservation map. I tried a few different attributes which included Agency name, County/State, Population and Tribal names/number.

I had a few minor issues with ArcGIS throughout the labs and I highly doubt that I could navigate the program without having the lessons in front of me, as many of the issues I had where typically ones I could not solve on my own. However, I did quite enjoy the process of working with HGIS which made my overall experience with this tool positive.
