Looking for GIS/GitHub Expert

My firm (National Demographics, Inc) is looking for someone both knowledgeable with GIS and familiar with GitHub to help us modify and use a GitHub-posted program (for an online GIS mapping tool) for a company project.

We seek a consultant to advise us on how hard it would be to modify that tool to achieve our needs, and perhaps to do the modification work for us. GitHub site and program here:

If interested, please contact Douglas Johnson, Thank you.

Neglected Dam Map

Thousands of people in the U.S. may be at risk from dams that are rated in poor or unsatisfactory condition.  An Associated Press investigation has identified at least 1,680 dams in 44 states and the U.S. territory of Puerto Rico that are considered to be high hazard and in poor or unsatisfactory condition.  A dam is listed as high hazard if its failure is likely to result in people being killed.  The dams and their date of last inspection have been plotted on an interactive map.  Looks like there is only 1 in California.


US Flood Risk Map

A new online flood risk map has been released by the nonprofit organization First Street Foundation.  The online tool can tell you the current flood risk for your home and possible future risks.

The flood model used by Flood Factor is based on models of flood risk from rainfall, overflowing rivers high tides, and coastal storm surge.  It takes into account such as factors as flooding history, elevation and proximity to water.  To predict future risk of flooding other factors are also taken into account, such as different climate models and predicted sea level rise and predicted future precipitation patterns in the local area.  Check it out!


NOAA Height Modernization Program

Last year I wrote about how our datums are changing.  NOAA is working on recalibrating the nation’s elevation data as part of its update to the National Spatial Reference System, expected in 2022/23.  The height modernization program corrects local elevation data which has not been updated since 1988.  GPS and gravity mapping are being used to update elevation.  Continue reading
