5. Then one year….. New Storm Surge and Evacuation Zones were needed
4 Counties had to be processed
ArcGIS was currently in ArcView 3.2 with AVE language
Automation would make the repetitive tasks so much easier

7. That served us well internally
Other regions were updating hurricane data sporadically
Then in 2008, the whole State started updating Hurricane data at the same time
What better use of a GIS tool then to simplify processing and promote consistency

8. Example of Possible Low Quality DEM Enhancement
We made do with the best we had at the time:
Example of Possible Low Quality DEM Enhancement
Here is a trial concept in enhancing poor quality DEM where good quality does not exist
This is but one example of possibilities to better surge results
This involves using aerial imagery as a boost to topography

Aerial RGB
Aerial Blue Channel

15. Still in ArcView, but at version 9
Coding was in VBA
AVE code had to be ported and updated
Assumed LIDAR Data already processed into DEM
Each RPC used it
Consistent results

16. Florida Statewide Regional Evacuation Study Update Program
GIS Technology Drives the Data & the Analysis
Each Region on its Own in the Past
First Statewide Comprehensive Effort Like This Ever
Product is for State of Florida with Regions as Sections
Compatibility, Structure, and Formatting are Key Elements
All ESRI 9.3+ with Spatial Analyst
Common Map Templates

17. SRES Program required updates….
As program matured, new products were required
Depth Atlas and resulting data output
Directional Atlas and resulting data output
New SLOSH Superbasin required reruns
All the while, ArcGIS matures and versions increase
