So, after deleting unwanted elements, moving them from Temporary Places to My Places, reorganizing, and renaming, I get a structure that looks like the image to the right.
This allows me to quickly select which items I want to see. When I turn on the Continetal US data, I can see an overlay for the entire county and where any action is. I recommend using only one or the other at a time, as they may not line up exactly over each other. However, in the Northeast, there is activity. Here is a sample of that part of the country showing the radar and warnings overlaid on the map.
So now we have a great map tool and have integrated all the weather data we want from the NWS. The next step is to add in the APRS data. Almost as easy as it was to add in the weather data, APRS. Just go to APRS. There is no profile or account; you can put in anything you want. On the right hand side of the map, under Other Views, you will see a link for Google Earth. When this item shows up in Temporary Places, it will load all the APRS locations for the past hour in the area of the map you are looking at.
This will include station locations, paths, and weather data. Again, we can notice that this is a network folder, by its icon, and not static content. This means it is talking to APRS. It is actually smart enough to know what region of the map you are zoomed to. As you re-zoom or move around the map, it will trigger a refresh of the data and it will pull in the APRS data for your current view.
It will also refresh every five minutes if the view does not change. Note to nerds: if you want to see how this works, right click and select Properties, as I showed above. Due to the large volumes of APRS data, it will limit it to 1, items on the screen.
So if you pull out to show too large of area, such that greater than 1, items would need to be drawn, it will display only some of them. A message will show on the screen indicating that the number of items was limited and to zoom in to reduce the area to see all items. In addition to general APRS traffic from the past hour, you can track specific objects. After logging into APRS. This will show just that item on the APRS.
However, now when you click the Google Earth link, in addition to the general APRS traffic folder for the last hour, you will get a second network folder for that particular call sign. It will show the last known location and path for that person, even if it was not during the past hour. If you have multiple calls you want to track, search for them on the site, add them to Google Earth, and move just those tracking folders from Temporary Places to My Places.
At the left you will see how I normally keep my personal My Places arranged. The Starting Location does not need to be checked. It will automatically set the map to that position. I can quickly add in my local or national radar as well as watches and warnings. So that completes the list of requirements!
We now have a map program, with live data from the NWS showing both warnings and radar data. We have direct access to the details on those warnings. We can see both local and national radar. And we even integrated APRS data and paths onto our map. So what does this look like when all combined? Take a look at this sample.
As you can see from this sample, having all this information together makes a very powerful tool for spotters or anyone at all. Since I created the original page above, the NWS has updated their loop capabilities. In the past, loops were hard coded to a specific time period. This means that when you added the loop, it worked for that time. However, if you came back a week later, the loop was coded to look at the original time one week ago.
