[Talk-us] San Louis Obispo CA area - Chimney Wildfire - OSM US

I just wanted to comment on the current state of nationwide datasets (most
States/Counties have better). The United State has a baseline of "official"
data available for free (general building outlines not being one of them).
This data is available to download and called HSIP Open. More datasets are
available to federal agencies and those working on federally declared
emergencies. I used to work on this project and its great for groups with
no budget for data collection or emergency responders who get put into an
The Dataset link:
When HSIP Open came out I did a small investigation in PA on hospitals to
see what one was better (HIFLD/HSIP VS OSM) and the results are mixed
(where there is active contributions OSM is better otherwise HSIP is the
only thing around).
Web Map showing "Official" vs OSM Sources
Hopefully someone can do a better analysis than I can (i.e. OSM vs
State/County vs Federal sources).
The US has basic GIS data available (a few years old but ~80% correct)
already. Awareness of OSM is growing and I also hope to help to push the
use of OSM data into broader usage. Use cases like this fire will only
help to bring more emergency GIS managers on board.
Great job guys,
