I want to use GRASS (and QGIS) for analysis of water well locations in
a town. The basic data has been provided thru (ARCWare) shapefiles.
While input of data to create the well location point maps is no
problem, the shapefile format embeds the "real" spatial location data
in a proprietary file (the .shx index files). So I can input shapefile
data, including the dBase attributes, I can't get at the spatial
locations; consequently I can't correct for any location errors made
as a result of data input mistakes. Is there a way to access these
shapefile index files using GRASS? Or is there a way I can use that
fact that I can produce a GRASS location map of points to obtain (say
a table of) (x,y) relative to some know location on the map? If I
could solve this problem, I could probably move the whole well data
set out of shapefiles and into more accessible database system, e.g.
MySql.
thanks,
