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.

possible duplicate of How to calculate te area between contour lines on a DEM with Qgis 1.8? - While different software, it is the principles of the area calculation which are relevant.

comment How to create polygon made from outside points of points shp?
There is an alternative. By the looks of it you have a regular grid of points (barring the gaps with arrows). Convert the points to raster directly (no interpolation) so that each raster cell where there is a point has a value of 1 and all other areas are NoData (easy in GDAL and ArcGIS). Just be sure to specify the same resolution as your interpolated raster. Then simply multiply your interpolated raster by this new one.

comment QGIS 2.6 - Point Sampling Tool plugin producing empty shapefile
Do both your layers have the same CRS and, if so, what do you get if you select your raster layer in the TOC and use the query tool at one of the points?

You must click on the fields in the dialog box and not the layer in the TOC.

comment Mapping variation within multiple categories using QGIS?
You need to substitute your own fields for the examples I have provided. The "cntry" field is your category (which dictates the colour) and the "value" field is what dictates how bright the colour should be. If "value" only has a limited range (say 1 to 10) then you will need to normalize it to a scale of 1 to 255 to avoid everything being black. see my last paragraph.
