comment How to run two PostGIS versions in parallel on Windows?
I don't have a problem with the postgresql installations, just figuring out how to install postgis2.0. The question is now a bit muddled as I updated it along the way, perhaps I should rephrase it.

comment Random sampling of raster using R
This may be extremely obvious, but it took me some time to realize that the value of any cell can be referenced by r[r "condition"]. So if you want to set all value of the raster that are 100 to be 1 you can write r[r == 100] <- 1. Thanks @whuber - extremely useful example!

comment GIS data for Singapore
Yes - I am interested in population data, land-use zoning and buildings (although I realise that is unlikely). Road networks would also be of interest.

comment How do I import/export KML to ArcGIS Desktop?
Salut @sabrina I think you should ask a new question by itself. Click on the Ask Question button at the top of this page. Also, it might be best to use google translate or similar when you ask your question so that as many people as possible can help you
