@eustatic mentioned:

For Surge data, you can SURGEDAT for the Whole Gulf of Mexico. http://surge.srcc.lsu.edu/ For New Orleans, i think the sustainable cities data has the 10 yr rain flood...

of course, FEMA has the HAZUS-MH https://www.fema.gov/media-library/assets/documents/5507

USGS has their estimation, based on photography (of course) https://pubs.usgs.gov/circ/1306/pdf/c1306_ch3_h.pdf

HUD map is based on NOAA data... https://www.nola.gov/getattachment/Safety-and-Permits/Floodplain-Management/Extent-Depth-of-Flooding-Katrina.pdf/

Hi! So, i think basically we have to dig into the resources above to try to find how we could build standard Leaflet layers around them. There are a lot of examples of doing this in the current layers in the library. Also https://leafletjs.com/plugins.html lists many adapters, like ESRI. So, if we can find either an API endpoint URL or alternatively an interactive map we can reverse engineer, we can figure out how to build layers from them. Make sense? It's a bit of problem solving!

@jywarren Yes, seems quite complex. Trying to understand the process.

@jywarren @sagarpreet-chadha There is no API as such of the mentioned resources to plot the flooding data on the map. There are only PDFs. Should I analyse the data manually and hard code it in a json file and use it?

sidntrivedi012 avatar Mar 10 '19 21:03 sidntrivedi012

Aha - ok, how about looking at this page: http://surge.srcc.lsu.edu/data.html -- it has MapBox maps, which are leaflet based. Looks like this file plumbs it, although we will need the keys to display too to explain the data:

http://surge.srcc.lsu.edu/surge_global_map.js

Sorry i had missed that the other sources were PDFs!!!

jywarren avatar Mar 11 '19 15:03 jywarren

Oohh this will be really great. Thanks again!!!

jywarren avatar Mar 11 '19 15:03 jywarren

Will go through the links and try to make a layer. Thanks :)
