Mapping amusing places
Thanks to my brother for this link to the Amusing Places website. Having spent many hours looking at OS maps (for example), this is an appropriate use of a Gazetteer. One wonders if the OS have already "flagged" up certain places in the UK.....

Concatenating in Windows
I was recently sent some LiDAR data x,y,z triples (i.e. x coordinate, y coordinate and elevation); actually, it also had intensity so quadruples I guess. Anyway, the data were extracted for a 1km2 area from multiple flight lines which meant I had multiple x,y,z values. Before importing these as a LiDAR LAS file I wanted to concatenate them. Easy to do in Linux but I couldn't remember how to do it in Windows. A quick Google later led me to this useful article over at Lockergnome. And for those too lazy to click, this for loop will do the work for you:
for %f in (*.log) do type "%f" >> aggregate.txt
