Chapter 1:
I find it interesting that the first GIS application was made in the 1960s, since I’m so familiar with it being such a technologically advanced application. It’s hard to picture it as anything other than the computerized web application that it is, which makes it intriguing to imagine it starting out as a singular computer database. This chapter did a good job of highlighting the benefits of ArcGis Online’s existence, particularly the increase in accessibility and collection of data from multiple mapping resources. It also seems to aid in the up to date nature of data, as there is a continuous inflow of data being inputted by various different studies. I thought it was nice to have a refresher on the basics of map creation, as many features are similar to desktop gis. Through the tutorial that chapter 1 had me run through, I am already recognizing the immense convenience of being able to create maps on a more mobile device rather than a PC. I would even argue that the formatting of the map curation in web format is much more user friendly and easy to navigate.
Chapter 2:
I find the distinction between hosted and non-hosted layers quite interesting, as it highlights the different ways the data from maps can be used. From what I gathered, hosted layers seem to be layers in which the data is all existing within the published layer, managed by ArcGIS and ready for other users to access, while non-hosted layers are published layers in which the data is managed by a user. There is a feature called smart mapping which I like the idea of, as it makes my job easier in this class. It is a user base that essentially aids in creating professional grade map visualizations without the need for expert cartography background knowledge. It can be in a range of styles and forms, such as dot mapping, heat mapping, vector field, etc. I found it interesting that there were so many strong similarities between web and desktop GIS, as many of the features being described in the chapter were aspects I was familiarized with when working with the desktop application, with one of these features being popups. I was not surprised to see storymaps mentioned, as it is an important aspect of GIS that helps share the visualizations you make. The storymaps were actually the first feature of ArcGIS that I had been introduced to while in another class. The tutorial that the chapter ends with was pretty easy to get through, using demonstrations revolving around population data as well as creating a story map. So far this formatting of GIS chapters has been much more manageable.
Applications:
I am heavily interested in Entomology, so I figured that I could gather data on Chinese mantids or lanternflies, as I find that those would yield some pretty interesting and valuable information to explore in spatial mapping. I could use some type of regional map, maybe limited to an area known to have one of the listed invasive species, and create a simple dot density map to display the data. Another interesting topic to look into would be Emerald ash borer sighting data and ash tree distribution, to look at the degrees of severity in different areas. I could even get more creative with the creation of that map because it would have multiple different features included.
