I built a similar website when working for a research lab ~2009. The lab is now closed, and thus so is the website but you can see some screen shots in this old time article: https://content.time.com/time/health/article/0,8599,2083636,00.html https://content.time.com/time/health/article/0,8599,2083636,... What was interesting how many jurisdictions got mad at me, because they thought I was targeting them. A hospital in Chicago that shut down their trauma center to save money but caused the south side of Chicago to loose 1 hour access thought I was targeting them as revenge over that action. The Florida Keys was mad at me because they had a hospital but no access and I'd be like "I'm sorry but that hospital is not a Trauma center and this is a Trauma Center access map, if the hospital gets certified I'd be happy to update the data". The hardest part was the data. I had to join the list of Trauma centers (levels 1 - 5, about 500 hospitals) with a hospital database (~5500 hospitals) to get additional information. I had to verify manually all the joins as well as the GPS coordinates. Its a shame the app got shut down, it had some useful tools. You could see trauma center access via ambulance, air ambulance, or both for 45 and 60 minutes. It also had overlays for hospitals, trauma centers (levels 1, 2,..5), stroke centers, VA hospitals, and helipads. I also built an additional tool in a similar app to 'build your own hospital system' by clicking on available hospitals and 'upgrading' them to a TC or stroke center and then see how many people in the state gained access.
