Computer things

Geotagger

I've created a bit of software for geotagging photographs by clicking on a map. It has its own page with instructions.

Levelling

I've made a page for reducing levels if you give it your field data. I've put it in this section because I don't know where else to put it!

PHP Map

I've also made a mapping tool which will colour in a map based on values you give to each area. The boundaries are drawn in AutoCAD and exported into a list of points using a macro. The PHP script then does all the fancy image stuff.
I've put a working example online here which includes data on water supply in the UK (I made this tool as part of a research project). Map size has been lmited to 500 pixels wide due to memory limits on the web server. If you're interested in using the code then drop me an email. On your version map size would only be limited by your processing power and your RAM
