Experiences with HGIS

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.

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.
