GIS Day Survey

I just sent out an email to all of the participants that we could identify, but if you did not receive that email we would appreciate your feedback!

The GIS Day Committee would like to thank you for attending the 5th annual GIS Day event, titled “GIS – The Power of Location”.  We hope that you found it an informative and fun day for GIS, and got some good swag!  In an effort to improve our event, we would ask that you fill out a quick survey to let us know what we did well, and what we could improve.  The survey will take around 3-4 minutes to complete, and has about 10 questions.

To fill out the survey, click on this link:


 Thank you, and we hope to see you again next year.


Fixing aerial imagery stretching in ArcMap 10.1 (or why does my imagery look so bad?)

ESRI has apparently made some unnecessary changes to the way it handles raster imagery in its newest version (10.1).  The County goes through great lengths in its imagery project (LARIAC – see website) to ensure that the imagery is color balanced and looks good natively.  When you added our data to ArcMap, it looked fine because the default setting was not to use statistics to stretch the imagery.

However, in 10.1 they have thrown this away, so now it looks HORRIBLE when loaded.  Thanks to some sleuthing by Todd Zagurski of Regional Planning, he has found a way to set the ArcMap defaults to not stretch the imagery.  Stretching uses the statistics of the image to enhance it  by changing its brightness, contrast, and gamma.

The instructions are fairly simple:

Customize menu > ArcMap Options > Raster layer > “Check the Enable Custom Rendering Defaults” and change Stretch Type to “None”

Weather related map services

I received some links for those of you who might want to embed weather related information into existing mapping sites.  The NEXRAD weather radar is a good one.  Thanks to Carol Ostergren from the USGS for passing along:
here are a few services

USGS Hazards & Warnings dynamic Link
NEXRAD Weather dynamic Link

NOAA Weather Watches and Warnings

NOAA’s Flood Outlook

I grabbed these from the geospatial platform. You can search for layers under the add tab.
