To assist Net Control Station (NCS) operation in a severe weather event, a script was written that will plot APRS users in GRLevel3. This is open to all radio amateurs operating with Denton County.
Spotters: Please add “!DCARES” to the comment text. “!SN!DCARES” will also work.
There are two GRLevel3 placefiles available to use: filtered and unfiltered.
If you wish to change the text color as it appears in GRLevel3, add the variables r, g, and b to the URL (as seen below). These variables associate with red, green, and blue respectively. The valid ranges are 0-255. With no variables specified, it will default to white.
…/aprs_placefile.php?filter=xyz&r=128&g=128&b=128 [this works for both filtered and unfiltered]
Unfortunately, I’m not going to publish this URL for all to use. If you’re an NCS and would like access to this URL, send me an email and I’ll pass it along.
