I am a freelance GIS consultant with specialities in 3D visualisation (e.g. www.deepmaps.co.uk and animated landscape models for public participation in planning), wind farm analysis and bespoke geospatial analysis.

Previously I have lead a small commercial GIS consultancy team in a large research institute, headed up a team undertaking a massive geo-data processing endeavour of entire country and world-wide data sets as part of an ambitious computer games development project before becoming GeoMatics Manager for the UK branch of a German wind farm company.

I 'grew up' on ArcInfo 6.x and migrated to ArcGIS, while dabbling with Idrisi and ERDAS Imagine. I now predominantly use open source software (e.g. GDAL/OGR, Shapely, PostGIS, OpenLayers, QGIS, GRASS, Mapnik etc.) and highly commend the OSGeo 'stable' to anybody looking for an alternative to expensive proprietary GIS solutions. Other experience includes WindPro, WindFarm, OpenWind, Blender, GIMP, Python and Eclipse.

comment No cadastral maps in the UK. Solutions/alternatives for a methodology?
@nhopton - I use the OS Open Data a lot but hadn't spotted these brand new datasets. The OS Open Map Local looks like an excellent improvement on the old settlement areas data (downloading now). So +1 for the heads-up!

comment Is it possible to mix italic and normal font in a label?
There is an old/existing feature request for this but I don't think it has been implemented (certainly not in 2.6). It certainly would be nice to have.

That's why the thin tool should be better than shrink.

comment Data values (measurement scales)
This sounds like an attempt for this board to do somebody's assignment for them. Even if it isn't, the question is so broad it is unanswerable in its present form.

comment Does interpolation create a vector or raster?
You can interpolate straight to a raster. However, whether is appropriate and how you approach the process (e.g. IDW, Kriging, TIN, RST etc) will depend on your data. I suggest you rephrase your question explaining what data you have and what raster you want/need (and how you intend to use it) and that way you may get a more informed answer as to which interpolation method might be suitable, otherwise this question is too open.

comment Colormap to grayscale map using QGIS?
Read the documentation. Also have a look here and here. A quick search will yield many other examples.

comment How to get boundaries of city?
Can you be more specific please. Do you already have some data from which you want to attempt deriving a city boundary or is this really a question along the lines of "Can anybody tell me where to find the data?". In answering both these questions, it would be helpful if you told us where in the world you want the data for. When you say you had no luck with ArcGIS, what do you mean? Do you mean ESRI's data or the software package?

comment How to digitize a raster automatically
NP - I've also updated to reflect that, subsequent to my original posting, Sextante is now called 'Processing' (added a link to that too).
