Designing Geodatabases for Transportation
J. Allison Butler
Books on the geodatabase tend to be oriented toward the introductory side (quite often geared toward teaching basic geodatabase concepts over a 16 week semester) or written at a level that is not attainable to the GIS novice. Designing Geodatabases for Transportation reaches well beyond the introductory level to provide a thorough explanation of the geodatabase, however it also takes the time to create a foundation based on fundamental geodatabase concepts.

Mapping at a hyper-local level is developing at a breakneck pace. The line between full-blown GIS and cloud mapping also fades at a similar speed. Last week Google made announcements of new features that may grant users even greater detail of local places than before and will provide the type of robust information that users look for in a conventional GIS. These announcements came from the Google Public Sector Blog and the Google LatLong Blog. (Check out the full post for more details)

Google Maps has produced a lot of tools making it easy to collaboratively create and edit maps, but those maps are still limited to Google's base layer information. At most you are able to create basic polygon and line information on top of Google's existing maps. While this is incredibly useful in areas that have been mapped more extensively, it doesn't really provide an opportunity to start from scratch in order to create visions for the future. The scale on Google maps can also be limiting in that you can only zoom in so far. If you want to create really robust maps on a neighborhood scale, you are probably pushing the limits of what Google can do in many areas (although data is increasingly complex in more populated areas). Tools available from UMapper allow you to take control of your map by importing your own image to use as a base map and overlaying data similar to what is available through the Google MyMaps application.

GIS for Decision Support and Public Policy Making Christopher Thomas and Nancy Humenik-Sappinton
GIS users can often times find themselves plagued with the GIS equivalent of “writer’s block”. Situations where all the data has been collected, you know what it is you are trying to show, you fully understand the decision to be made, yet the steps necessary to pull all the information into a cohesive analysis remain elusive. In these situations, it can be extremely helpful to have a fresh outlook to aid in brainstorming ways that the analysis can be performed and how it can be presented to the end-user.

Google Maps provides an extremely intuitive and almost fun to use interface, unfortunately it still lags behind the accuracy of a full-blown GIS. The ESRI suite of products is extremely robust but unfortunately, some tasks can be a little daunting. While not suitable for every situation, there are a few tasks that can be streamlined by combining the relative strengths of each product. However, getting data back and forth between the two products can sometimes be a bit of a chore and can be time consuming. The data sharing tools provided by GeoCommons.com are really helpful in making that data exchange virtually seamless and less painful. (More after the jump)
