    N131PR quarter mile parallel lines flight pattern

    last night i was outside and noticed a low, slow flying aircraft on a flight pattern that didn't look familiar. it seemed to be going back and forth in the same line across the sky. checked flightradar and it's a dc3 at about 10k puttering along at 150mph. flight path was a series of parallel lines spaced about a quarter to half a mile apart. you can check the flight here: flightradar24.com/data/aircraft/n131pr#2114f7d6

    i figure this is some kind of survey, i was wondering if anyone had any ideas what it could be.

    Be hard to tell. They are a platform for whoever hires

    From the patterns and the locations I'd suggest a hi-res photographic flight. Various authorities keep their land use mapping up to date this way. As Oblivian writes, the operator offers a broad range of services and it doesn't give any specific hints.

    Incidentally the aircraft is a modified DC3 with turboprop engines and is registered as a Basler BT-67.
