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 What Does the Cell Value in a Composite Raster Mean?
What version of QGIS and Grass are you using? Also, please state your settings as they impact the operation (and therefore calculation of r.composite). Interestingly, I consistently only get RGB and no composite band in 2.4.

comment Converting *.asc to *.shp without using ArcGIS for Desktop or QGIS?
I think you'll get a better answer if you add a little more detail to your question. First, not all asc files are the same. Can you show a sample including the header? Secondly, are you trying to convert it to a point dataset and third, when you say you cannot calculate the records, can you be more specific as to the problem you are having (e.g. is it a coding issue, a problem understanding the shapefile format or understanding the asc format)?

comment Looking for an open-source Java based GeoTIFF library
Why don't you incorporate the GDAL libraries directly into your project? This avoids the undesirable separate install. GDAL has a Java API released under the X/MIT licence (i.e. open source and allows for redistribution etc like GNU).

comment Importing raster and vector: GRASS GIS 6.4.4
If you are using QGIS (especially a recent version), you don't have to import your data into GRASS. Just load it as a layer in QGIS and then use the GRASS functions from the Processing Toolbox (FKA Sextante). This way you can sidestep GRASS' quirky project setup process and just get on with using its great tools.

comment Pattern Effect in Pie Charts in QGIS?
With the above method, you can also increase the resolution of your piecharts layer. You could scale the whole image to be, say, twice the size and thus improve the sharpness (use thin black lines when making the pie charts). You then need to tweak the WLD file. If you double the size of the image, halve the X and Y dimensions in the WLD (check out how a WLD works if you are not sure - there are loads of threads about world files on this board).

comment Pattern Effect in Pie Charts in QGIS?
Fair enough! I have no nice solution in QGIS (I don't think there is one) but I do have a very nasty work around (see below).
