1)GIS has 5 parts: hardware, software, data, procedures, and people. It manages, captures, and stores data. Spatial data is information that represents real world data. Attribute data is information about spatial data.

Base maps are provided by arcGIS online. it increases the accessibility of GIS and map making/spatial analysis.

Web maps allow information to be retally available to many people at once. On a similar note the open data movement provides the public with accurate data.

Point, line, and polygon data is called vector data.

Things that are similar can be grouped into layers on a map.

Raster is recorded or measured data for any location on the surface to form a digital surface.

2)simple technical elements of GIS: map, analysis, insert, and view.

context planes allow you to modify the map

Shows how to connect folders to maps

3)created multiple layers to compare the differences.

Talks about data relations

Changing attributes

4)using and creating geodatabase

learned how to limit geodatabase highlighting information I think is relevant

Create lines and polygons

5)played with commands, reminds me of coding in high school

Use tasks

Enjoyed the more technical side of gis

 

 

 

 

 

 

Once I worked past all the bugs I enjoyed getting to use the software and I found that there were somethings I could figure out without the book just by poking around. I enjoyed the work i could do with the data tables and reminds me of the coding class I took in high school. I wasn’t able to get the 3d model to work but I was able to work through most of the other stuff. I will take more screen shots in the next chapters I was quite focused on getting the work done.

Chapter six:

Chapter six focused on collaborative mapping. One thing I noticed was that in exercise 6A, the chapter mentions an “empty row” below the LandUse row, but I found no empty row below the software( I found out later that someone had already made those changes and used the computer before me). The only thing I got stuck on was publishing the web layer since I didn’t sign into ArcGIS Online. This exercise was easy to get through, and I didn’t struggle as much as I did last week. 

In exercise 6B, I worked on adding the tree inventory web layer to my map. The work was all done on ArcGIS Online(the web browser). It was very laid back, and I didn’t have much trouble setting up everything. In exercise 6C, I learned how to work on the ArcGIS Collector app. I found that the app name had changed because it showed ArcGIS Field Maps instead of Collector.  However, those are the only problems I have had with this chapter. Chapter six felt very laid back and less chaotic compared to the last five. 

Chapter seven: 

Chapter seven focused on geo-enabling the project. Exercise 7a went pretty well, and I didn’t have to fuss around a lot. One thing I noticed is that there is no “Appearance” tab, as mentioned in the textbook. Symbology is a part of the Feature Layer tab. Exercise 7b, too, was quite easy to operate, except I couldn’t find the “locate” pane for the last step. Exercise 7c was great at first, but then I started struggling with finding the “Data Management” pane. I just used the merge tool from the edit tab to move forward with the project. 

Chapter eight: 

Chapter eight focused on analyzing spatial patterns. I’ve created a kernel density map using Python before, so I was very excited to get started with exercise 8a. The exercise was pretty easy, although it did mention the appearance tab, which I can’t find on the software anymore. Exercises 8b and 8c also turned out to be very chill and fun to explore.  

 

Chapter nine: 

It was easy to get through this chapter, I didn’t have any problems while working with it.

Chapter ten: 

The only problem I had in this chapter was that my map didn’t fully match the map shown in the textbook

I think overall, I’ve definitely gotten better at handling the software.

Here is a PDF with my work, comments, and issues for chapters 6-10.
