Greetings GRASSers:<br><br>First I'd like to say what a great book the Open Source GIS: A GRASS GIS Approach (3rd edition) is. It is full of great practical and conceptual examples. Well worth the money to anyone who has not purchased it yet! Also a big thanks to the developers and users of GRASS who make it a powerful and amazing GIS.<br>
<br>I have an ascii table of lidar data. The columns are x,y,z, and a fourth column containing an integer code of some sort. I have looked at the example in the man page about how to select columns for importing via some shell manipulation of the input ascii file, but I do not think it is applicable to what I'm doing (or perhaps the caffeine boost is not in effect yet). I have also tried various combinations of parameters in v.in.ascii.<br>
<br>I would like to import the XYZ to build the geometry for 3D points, and have only "Cat" and "Code" in the attribute table. ("Code" being a column name for the 4th column in the input ASCII). I cant seem to find the combination of column definitions and other parameters to achieve this. One option seems to import them all as "x double, y double, z double, code int", and then after the import, drop the x,y,z columns. Is it possible to put the first 3 ASCII column values to the geometry, and use only the last column as an attribute?<br>
<br>I'm using GRASS 6.2.3 and sqlite database.<br><br><br>Thanks out to anyone with some feedback.<br><br>Mark
