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 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).

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).

comment How can I get a .asc file to load into QGIS?
File extensions are not sacred! The only geographic data in the file are the mark positions. The rest seem to be spray data as user30184 says. The marks could possibly be either waypoints (giving a route along which spraying is done) or field identifiers (isolated points around which the plane sprays). Therefore, your knowledge of the data is essential to determine how to handle it correctly. You need to write a simple routine to parse the file. You could create a table with fields mark, lon, lat and maybe flight time and mean application rate (for example). You can then import it into QGIS.

Why can't you use colours? That would make it easier to differentiate.

True - but that's a specific use-case. The OP didn't specify Mapnik so maybe Osmosis can provide a solution.
