Just browsing maps and spotted this: track planning by tractor  Those lines are dead straight and parallel, and all the corner radii are equal. Amazing. How is it done on a tractor across a ploughed field? p.s. don't visit that site if you haven't got an hour to spare. You can swap instantly from old 1" OS maps to modern Landranger by clicking the red copyright button -- great for tracing closed railways. Martin. |

By coincidence I was looking at exactly this type of thing yesterday; there's some fascinating stuff to glean from these satellite images. I do a lot of photography for the Geograph web site, and "Where's the Path" is an invaluable tool for locating precisely where the pic is taken from and where the subject is located. Nigel |

I got this rather curious pop-up message: "<wtp2.appspot.com> New for biological recorders! Pointer formats in gridref or DINTY Tetrad + Watsonian Vice County (double click pointer text to select). See Help for more details. Thanks to herbariaunited.org ." I wonder what it means!  |

See: http://www.kmbrc.org.uk/recording/help/gridrefhelp.php?page=6 Note that the usage meter on Where's the Path? is currently showing red, so the OS-derived stuff may soon go off the air until tomorrow. (OS limit the number of page views permitted under the free Open Space scheme.) regards, Martin. |

Hi MartinThose lines are dead straight and parallel, and all the corner radii are equal. Amazing. How is it done on a tractor across a ploughed field?I don't know a lot about tractors, but I know that a while ago there was talk and some prototypes of tractors that used GPS to guide them. Type "GPS guided tractors" into google and there is a plethora of information! Cheers |

I learn something new every day: They'll be attaching GPS to the cow's legs next, so that the herd crops the grass evenly! Martin. |
