Week 6 Georeferenced Map of UWF
This is a georeferenced map of the beautiful University of West Florida campus.Two aerial images are coaxed to agree with coordinated data. The North image required 18 control points, to achieve an error of 9.70094. The South image required 48 links, to achieve an error of 8.9088 for the third order polynomial. Amber's office is near the big tree, you can see her waving at the satellite (if you look very closely).

Week 5 - Florida Map 3
Week 5 - Florida Map 2
This map reflects the extensive Land Cover for Washington County. Features with a 'count' of less than 2000 were removed to simplify the overall presentation. 'Count' is difficult to quantify, as I tried classifying the data, and the mean was 30?
Roads were included as base data for observer orientation. City names have a 'Halo' for visibility. The most challenging issue was finding Land Cover by County, as Statewide data requires hours to clip...
Week 5 - Florida Map 1
This map shows vector data for Washington County Florida. There are few cities/towns in this area, substantial wetlands (including bogs and swamps), and a road network that avoids wetlands. Public lands are identified as well.
I was surprised to see how much of the wetlands were not associated with the hydrography polygons. The major challenge was querying the wetlands layer to eliminate redundancy with lakes, rivers and other hydrography entities.

Animated Map of Unemployment by County
Interesting animated map of changing unemployment rates. My wife (a map widow) forwarded this to me :) Thank you Jeanie!
I had to shrink the size of the Flash window to fit the blog format, so the legend text is no longer legible. If I get a chance, I'll clean it up... You get the idea anyway, how elapsed time can be displayed. Cool, eh?
