Out of bounds range limit option

[michaelgeorge001]

A feature that I would find useful would be the ability to drop entries based on out of bound ranges - like 181º longitude or -92º Latitude, or distances like 14097.2 km.

Maybe a range limit command switch like -R LAT 90 LON 60 DIS 300, or something similar.

Hi Mike, what is your goal? To remove them from the webclient or from all output? The first is fairly easy to achieve, the second a bit more tricky as distances are calculated at webserver level and not available when sending out, e.g., UDP messages.

Hi Jasper,

I'm sorry, I should have been more specific. My goal was to just remove them from the webclient because I've rarely noticed them on the services like Marine Traffic, VesselFinder, etc.

It's not a showstopper item for me but just one of those things that made me laugh. Like when I see a ship at 91ºN, or at Lat -80.55, Lon -139.04167 ( Continental Antartica) when I'm in Nova Scotia (tropospheric ducting aside). I do have fun teasing my wife about how well my homemade AIS antenna is working out.

Great. One option (with the latest clone) is to use the below plugin that filters out ships > 1000 nmi away from the station. In practice I always rely on the validation flag. But not validated ships will still be shown on the map.

We could refine this to use a shorter distance but still include ships further out if they have been validated as genuine by the engine (the shipcard and table have green indicators).

Let me know if this works for you.
