-------------------------+--------------------------------------------------
 r.what is currently the most efficient tool for sampling (single) STRDS at
 point locations.
 Usage of r.what for space time data sets however is hampered by the
 current limit of 400 maps. Would be nice if that limit could be overcome.
 Memory may be an issue in case of thousands of maps?

 See discussion on the mailinglist:
 http://thread.gmane.org/gmane.comp.gis.grass.devel/62452/focus=62472

 In that context also an option/flag to choose between vertical and
 horizontal output would be useful (columns for thousands of maps will
 probably trouble spread sheet software).

 Finally, when using a vector map as input it would be nice if the category
 (or content from another column) could be written into the "site name"
 column of the output, so a resulting table can be linked more easily to
 the original data.
