ARES Southeastern US Situational Awareness Map Updates - 12 June 2025

Before diving in to the discussion about changes, I think I'm going to start using this blog as the notification outlet for the Situational Awareness Map. Normally when I do updates and I need to get word out about key changes, I'm cross-posting between a couple of Facebook and Groups.io sites. It gets clumsy, and I have to keep my comments short to fit the various platform restrictions. Using this blog allows me to be a bit more 'expansive' in my comments and discussions about changes.

Now, on with the show!

Yesterday I pushed out a few key changes to the map that wrap up some content updates and a few minor layout changes. Let's have a look.

Since the 2025 Hurricane Season opened on 01 June. I set the NOAA Active Hurricanes layer to on by default. This means any NOAA-released hurricane & tropical storm information (tracks, probability polygons, etc.) will automatically appear and update as NOAA releases information. This layer will stay on by default all the way through hurricane season


Under the Situational Awareness layer group, I added a Current Wildfires layer. This data is hosted by the Department of the Interior, and provides basic information on current wildfires across the US. This layer is off by default:


Let's spend a moment discussing repeaters. After a few years of hosting Repeaterbook.com info in the map, and getting very little feedback on Georgia repeaters (good or bad) - and zero info on repeater data from other states - I've decided to take a different approach. I've dropped the Repeaterbook.com coverage, and have gone back to an internally managed repeater database for just Georgia. This new data can be found in the Georgia Amateur Radio Repeaters layer. What you see in the map today is a slight update to the old Georgia Repeater Database Initiative information. I can take direct updates to repeater information, and can make quick changes - new repeaters, off-line repeaters, changes in repeater location, etc. I will likely put up an on-line form to capture this info, and link it in the map, but that's still a few weeks off. I'm also using a data clustering display tool, which is why you see a bunch of large dots when you turn the layer on. As you zoom into the map, the repeater data will 'dis-aggregate', and  you'll be able to get all the way down to individual repeaters. This layer is turned off by default:


Next up... PSAP boundaries. This one caused a slight stir a few months ago when I put out the word that the Dept. of Homeland Security pulled down the national PSAP (Public Service Answering Point) boundaries layer, and I had to take the layer out of the map. Not that anyone actually used the boundary info, they were just incensed that DHS took it down. Conspiracies, and all that. Folks, it happens all the time with this cooperative mapping platform, not just with national level datasets, but with very innocuous local datasets like local bird sightings, or community-level Girl Scout Cookie sales point layer (yes, someone made a cookie sales point map layer). I do it in my regular job as a GIS program manager at a very busy international airport. Data layers often age-out, security restrictions get imposed, or we just come up with new ways to display the data. So we pull down the old and (usually) put up something new. It's not just me and the DHS doing it - NOAA does it, the Georgia Emergency Management Agency does it, local governments do it, DOT does it, FEMA does it - everyone does it. The real issue is that there's no built-in notification system that lets map authors know a data layer is no longer available. The map just throws an error when you try to open it and a data layer is no longer available. So, back to PSAP data. Yesterday I discovered that the State of Georgia has published its own PSAP data layer, and I've added it into the map. You'll find it under the Borders, Operational Boundaries & Geographic Features - Georgia layer grouping. This layer is turned off by default:


Let's wrap this up. The last thing I want to talk about is finding layers in the map. There are over 50 individual data layers in the map, and the layer structure is complex. It can be tough finding the exact layer you want to take a look at. Heck, even I get lost in the layer stack! That's why I've incorporated a search tool in the Data Layers window, to help you find what you are looking for. It's the little search icon in the upper right corner of the window:


Let's say you are searching for a layer that shows lakes in Georgia. You heard the layer is in the map, but you don't know where. Just open the search tool and enter 'lakes'. The search tool will find the layer group that 'lakes' is nested up under. Simply expand the layer grouping to find the Georgia Lakes & Ponds layer and click the check box to turn it on in the map (it's normally off by default):


That's it for this update. As always, if you have any questions, feedback, or would like some instruction on how to use this map just let me know. There is a feedback button in the map, and it's the best way to get my attention.
