comment Why does the peak of a mountain appear bright on Radar images
I think you answered your own question " slopes facing the radar will be foreshortened and ones facing away from it will be lengthened from their horizontal(map) dimensions. The former will therefore be brightened and the latter dimmed. " en.wikipedia.org/wiki/Synthetic_aperture_radar#Image_appearance

comment Quick question regarding geocoding limits on google's API
it is calculated from the first geocode with the key (it is cached by google) as soon as the ip/domain is on 100,001 the status changes. We solved this by using FME to count each api request and stores it in the db, when the count gets to 100k it pauses 24hrs. (we also slow our requests down to 0.5 a second).

comment Leaflet's shapefile plugin only compatible with Firefox
I zipped a shapefile up and drag it into the leaflet.calvinmetcalf.com/#3/32.69/10.55 site it loaded correctly - it took a little while in chrome but worked - you might be better using the export to leaflet in qgis... I find it works much better qgistutorials.com/en/docs/leaflet_maps_with_qgis2leaf.html

In September the Environment Agency will be releasing Lidar data for England you will be able to see hedgerows and use GIS to extract them for your project. see environmentagency.blog.gov.uk/2015/06/16/… "From September 2015 all our LIDAR data will become Open Data and everyone will be able to use it for free."
