NOAA Imagery of Flooded Areas

Louisiana Swipe Map of August 2016 flooded areas by ESRI

Lynn Dupont has forwarded a link to a mapping application prepared by ESRI's Disaster Response Program utilizing recent imagery provided by NOAA's Remote Sensing Division. This is available for all users. Find the mapping application at this URL:

This imagery was acquired by the NOAA Remote Sensing Division to support NOAA national security and emergency response requirements. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne digital imagery. Individual images have been combined into a larger mosaic and tiled for distribution. The approximate ground sample distance (GSD) for each pixel is 50 cm / zoom level 18. (metadata)

Many thanks to NORPC's Principal Planner/GIS Coordinator Lynn Dupont, ASLA, GISP for forwarding this vital and timely information to us. Lynn has informed us that additional flood mapping products may soon be available. She writes:

Since there are more planners using GIS and remote sensing data these days, I will send information about flooding products to you and you can determine as to if, or how to distribute.  Some of the products are restricted use since they come through the International Charter and cannot be used outside of government, but the derived products from these data are not restricted.  We should be getting depth grids and updated flood extent polygons soon.  I will send information to you three as non-restricted GIS/RS products become available.
Currently, all efforts have been on ensuring that we are collecting data from all international satellites (mostly radar that sees through the clouds) that were able to collect over the flooding days.  The data is shared from these nations free of charge to the US for natural disasters within the space charter participants.  Louisiana has 4 trained project managers who work the charter, so we are well covered.  Yesterday we were able to adjust the collections to include more of St. Tammany since the area had not received direct input from the parish.  As flooding continues, we expect to continue collections.  The focus is getting the data to processors to produce the flood polygons and depth grids.  Most of your FEMA and Red Cross sites make the Civil Air Patrol and other FEMA and NOAA data available.  The flood polygons and depth grids as used extensively both in recovery and future planning.
