The exercises from the ArcMap Tutorial are fairly clear and
straight forward with only a couple exceptions. One of which is the outdated
tutorial. ArcGIS should update the tutorial when updating the program itself to eliminate unneeded confusion. ArcMap is a complicated
program with a fairly steep learning curve and instructions to include spaces in
formulas are very misleading.
Exercise three proved to be challenging due to the
inaccurate instructions from the tutorial. The instructions concerning the
formula input for the population density were incorrect and after trying
several times to follow the tutorial directions with the same result – no data
in the attribute table for the population, pop_den columns, I removed the spaces
from the formula according to the tutorial and the data was where it needed to
be. This was the most challenging issue I faced during this tutorial, but it was
resolved rather quickly after speaking with a classmate concerning the formula.
Self-paced and thorough, this ArcMap tutorial was at times
an exercise in patience, but overall a great introduction to one of the most
useful mapping programs available.

Neogeography is a user-friendly way to share geospatial data with friends and relatives without having to learn the complexities of GIS. The applications are usually free, easy to use and provide enough variety for most users to create a fun, easy-to-follow map.
ArcGIS and other scientific data integration tool users require more precision than the average google maps user making a walking map of San Francisco to share with friends. Neogeography is more subjective and recreational, and while user-friendly geospatial data interfaces are a great tool for the user to share their interests and experiences, substituting google maps and google earth for ArcGIS is not practical for social, environmental or geo sciences.
