Filtering Hills: List all Hills in any given area


In addition to being able to filter all the hills in any given 100km OS Map area like this:
www.haroldstreet.org.uk/waypoints/download/?area=NY

we’ve now also added functionality so you can list the hills in any rectangular area between two grid references like this…

For 6 figure grid-references… 

www.haroldstreet.org.uk/waypoints/download/?area=NY123456-NY456789
gives all the hills between grid references NY123456 and NY456789. 6 figure grid references give a 100m resolution.

For 2 figure grid-references… 

www.haroldstreet.org.uk/waypoints/download/?area=NN55-NJ55
gives the 100km square from the top right quarter of NN (i.e. from the middle at NN500500) to the bottom left right quarter of NJ (i.e. from the middle at NJ500500 including the bottom left corner of NH and the top right corner of NO.  2 figure grid references give a 10km resolution.

 

Other Grid Reference types also work…

4 figure grid references  can also be used like this…
www.haroldstreet.org.uk/waypoints/download/?area=NN1234-NN5678 . 4 figure grid references give a 1km resolution

 

8  figure grid references  can also be used like this…
www.haroldstreet.org.uk/waypoints/download/?area=NN12345678-NN23456789 8 figure grid references give a 10m resolution

    Can you tell me exactly how to filter? What I want to do is establish how many of the Munros qualify as Marilyns (or vice versa)

    This page explains what you want…
