[GRASS-user] importing gridded xyz data with titled grid

[Julian Burgos]

Dear list,

Sorry if this is a basic question...I´m taking my fist steps with GIS/GRASS.
I have a relatively large dataset (~250000 rows) consisting of lat, long 
and a data value.  The data has been collected in a regular grid, but 
the grid is "tilted".  In other words, along a row the latitude values 
increase constantly, and along a column the longitude values do the 
same.  I need to to convert this data to a raster file.  I have no 
information on the native projection of the data.
Any ideas/tips/suggestions on how to tackle this?
Many thanks,

I have a large dataset
