I have a vector of data points that I imported from a CSV file (which was

need this file so I can assign different colors to data points based on the
value of the datapoint. The vector is imported correctly, but the DBF is not
created.
v.in.ascii -n input='/Users/ryan/Desktop/Desktop Stuff/ems/responseTime.csv'
output=response format=point fs=, skip=1 columns='y double, x double, z
double' x=2 y=1 z=3 cat=0 --overwrite
What am I doing wrong? I have attempted this with both the GUI and the
command line and both with and without the quotes as suggested in a previous
post. DBF files for the other vectors I imported (from ESRI) are showing up
though.
Just a guess, but are there only the x, y, and z co-ordinates in the CSV
file? If there are no other fields and you're creating a 3-D vector as
here then perhaps it tries to be clever and skips creating the database
table?
I would suggest leaving out the "z=3". If you are using the z co-ordinate
as an attribute and want it to be in the database then it doesn't really
make sense importing it as a 3-D co-ordinate. Also I notice it should be
considered (IMHO) a bug, or at least a documentation bug in v.in.ascii
that it automatically creates a 3-D vector if you specify the z= option,
even if the -z flag has not been specified - what's the point in having
the -z flag anyway if specifying z= automatically assumes you want a 3-D
map?
Does leaving out z=3 lead to any success?
