Digital mapping tiles


Recommended Posts

Why don't you use a drone to take a photo. They go prity high and have a fairly wide camera lense. For a tree survey I took a photo of a clients 13 acre property and the drone was only half way up and I had to erase a lot of the neighbouring properties garden aswell.

For mapping you want a long focal length, with a wide angle the distance to the object just below is a lot less than the distance to the edges to there is a problem rectifying the image so that all points map to a grid. If you take the same area from 3 miles up there is not much difference in distance from the corners to the centre.

 

Still better than nothing though and mapmaker has a rubbermat routine that allows you to pull areas of the image to known points on the ground.

Ordenance Survey seem to have finally woken up to to mass distribution of their digital maps. Rather than having to buy from Memory Map or such like, you can take a £19.99 annual subscription for all of the UK. It all runs in a web browser, and the licence covers Desktop computer, mobile devices, smartphone etc. It allows printing of full page maps, route and waypoint plotting. Seems to be very good value.
