Projections, Part Deux


Hands down this was the most challenging lab assignment to date in the GIS program.  The overall learning objective was to get used to collecting various datasets and re-projecting them into a common map projection.  In this case, we used aerial images from Florida agencies as well as raw data from an Excel spreadsheet and needed to convert them all into the same map projection.  In the case of the data points (the  STCM point data) this involved a two-step conversion process.  We also needed to clip the major roads and STCM data to only present the data that applies to the two quads we chose to map.

This is a lot of data to get on one page.  I'm not super fond of double inset maps as I think they tend to take a lot of real estate for minimal return, but I was happy with the end result here.  The key communication goal is the location of the tanks and their relationship to major roads seems clear and the scale is not imposing.  The middle section looks well balanced, left to right, and the items of lesser importance fill the bottom panel.
