DISTANCES

GCS 1984..............6,934.48 miles

Meractor.................10,112.12 miles

Behrmann...............8,763.08 miles

Quartic Authalic......8,524.10 miles

      Map projections are an important part of GIS and geography in general. Different projections offer  certain types of information or project certain information better or more accurately than other maps. For example, one map might be better for measuring distances while the other is better for mapping elevation. Location can also play a big part in the desired map projection.
      If a person needs a top view of the earth around the north pole, a mercator or behrmann map wouldn't be the best choice. A equidistant conic map would be a more suitable option in that case. Picking the right map projection is crucial for finding the distance between two points as the distance exercise in this lab clearly demonstrates. The distances are up to 3,200 miles apart between the GCS 1984 and the mercator maps, which even on a global scale, is a massive difference in milage.
     

      Arc map was a pretty cool piece of software in my opinion. It's simple enough and useful enough to be used my a multitude of people. It has vast capabilities to be useful to many people including businessmen, construction contractors, surveyors, and the like. Although most of the time if it was needed they would hire or contract to a GIS trained individual or company. 

      The software itself had a lot of handy tools that were especially helpful. Number one was the table of contents, it was an incredible simple tool but one that turned out to be very valuable by being able to turn layers on and off with a single click of a mouse. Setting up legends, scales, direction arrows, titles, and other map accessories was simple to setup as well. Also, switching layers between maps turned out to be as easy as dragging or copying and pasting within the table of contents.

      Some things that turned out to be not so simple were combining data tables, creating summary statistics, making a graph, adding from arc catalog, and other procedures turned out to be a little more involved and confusing. Most of the time it was because the tutorial version and the current arc map version were different so it took a little time and effort to figure out the proper steps.

     Overall, most off the procedures and tools seemed like they could be learned in a short time with proper practice. The software was mostly user friendly and had easy to understand visuals. I can definitely see the full potential of this program with the right amount of training.

     Neogeography has dramatically improved the interactivity of online maps that help users locate desired services and locations. Users can browse online maps of familiar an unfamiliar areas alike to get  an overview of the area at a glance. Integrated search options confine the results to give the user results that meet their criteria. In many cases, these features streamline and expand the capabilities of online maps.
     The drawbacks that this technology can cause is that users can become too dependent on its use. If a person was faced without the option of advanced mapping who overly relied on them, they might not be able to interpret or navigate a regular map if faced with that option. Also, there is the potential invasion of privacy as technology continues to grow and advance. Some people might already consider it borderline.
