comment Rasterize vector with gdal
as Curlew said, you need to specify size and seems like the plugin doesnt have all the functions so you have to do it using a command line (GDAL command line). You can get centroid of polygons by vector->geometry tool->polygon centroid and export it. Then you can do Vector->distance matrix. and it will give you distance in a matrix. Make sure you are in projected coordinate system.

and i guess its not straight line, you need route distance?

comment Rasterize vector with gdal
distance from a polygon is a very vague term. You want the distance of the point which is nearest?

comment Classifying small structure in water using IR band
well. The idea is good but all the beacons are unknown. May be I can visually test and make a test set. Not sure though.

comment Classifying small structure in water using IR band
no. No spectral information I can attach. For now, I am going for 5m Rapideye and structures are 20x20 to 30x30 m.

comment Floor height creation from Aerial Lidar/Imagery only
So what I understand from your question is that you want the height of ground floor above the surface using LiDAR data? I don't think you can do this using aerial data. You only have values at points which are visible from above and your ground floor is not visible. I am curious if someone can give some more valuable input. Cheers N
