comment How do I use EllipseMarker in QGIS 1.8?
Is there a reason why you are using v1.8 and not v2.8?

comment Is there a way to add x , y, z coordinate to the attribute table of polygon in ArcGIS 10.1?
Then you need to export the nodes as points, then calculate the x,y,z. If you have a unique ID for each polygon, that ID will come over when you export/convert the nodes to points. With that, you can relate the nodes x,y,z back to the polygons. Really there isn't any other way.

Looks like you need dissolve the neighbouring polygons first

I am not sure I am understanding your issue. According to your comment, you need the x,y,z centroid of the polygon. The process described above will provide you what you need. I would suggest that you edit your post to clarify your requirements, as well as provide a screen shot of our issue, so that others can visualize what you are asking.

comment Drawing 100x100 meter with 5 rows and columns grid centered on one point for multiple points?
Do you want a grid around the buffer, or a grid inside the buffer?

Would a buffer work? There is an option to make it flat not round, which would give a squared cell look.

comment Is there a better way to convert Raster to Point data? Don't need one point for every cell
what about a raster calculation to remove cells you are not interested in. Alternatively, you could convert your rasters to polygons, and use the polygons as a means to select/delete points (ie: no data, or other land use).

comment Computing population exposure
Good point Joseph. I haven't used ArcGIS in some time, so I am unsure if that will be a requirement. There may be some work post conversion.
