I’m just finishing up a contract making maps of telemetry data from satellite tagged animals. Basically just finding daily positions and making a pretty map out of them. It’s taken me a little while to write the code for it and while I’m not sure a whole lot of other people will be able to use it, I thought it might help one or two people out if I posted it online. The boss ended up wanting that as part of the contract too so pretty good motivation.<\/p>\r\n
It’s not completely automatic but if you want pretty hexmaps of animal positions and you’re reasonably proficient in R<\/a> (with maybe a little knowledge of GMT<\/a>), then this may save you a good bit of time (or least let you skip some of the stumbling blocks I ran into). There’s also a function to read the output from the Douglas Argos Filter<\/a> which could be handy if you’re working with Douglas filtered data in R.<\/p>\r\n
