Georeferencing, Editing, and ArcScene

New this week were the topics of georeferencing and the use of 3D ArcScene. 

Georeferencing refers to the process of configuring a raster image to the proper place in the map.  By aligning non-referenced points with referenced points, you can take an aerial photograph and properly align it with your existing points and line shpfiles.

ArcScene allows us to display and examine data in three dimensions.  Through use of DEMs and attribute data, ArcScene can "elevate" your data display to a whole new level.

Dot Density Mapping

Dot density maps are used to display conceptual data (raw totals).  Each dot equals a certain amount of some phenomenon and the those dots are placed where that phenomenon is likely to occur.  You can use a dot density map to show such phenomenon as population density or harvested crop totals.

Geocoding, Network Analyst, and ModelBuilder

Week 12...we are getting close to the end of the term!  This week's map consist of two frames, one contains the geocoded addresses of EMS locations for Lake County Florida.  The second, smaller frame contains an optimal route that was created using Network Analyst.  

We also briefly looked at ModelBuilder.  It reminded me a lot of DTS packages in MS SQL.
