[gdal-dev] RE: gdal_rasterize utility

[David Hildebrand]

I am trying to rasterize a set of points from a CSV file with
coordinates.  I have created a VRT file to define a virtual 2D layer.  I
am using version1.7 so I need to copy a template output image file to
rasterize (output.tif).  The field "abl_val" contains the data I want to
rasterize and "f_year" and "f_period" are filter attributes.  I use the
following syntax in my rasterize command.  

 

gdal_rasterize 

  -a abl_val -l alberta_out -where 'f_year = 2010 and f_period = 16 and
abl_val is not null' Alberta_Out.vrt output.tif

 

I simply get the standard usage message below indicating that my syntax
is wrong.  Yet, I cannot see it.

 

Usage: gdal_rasterize [-b band] [-i]

       [-burn value] | [-a attribute_name] | [-3d]

       [-l layername]* [-where expression] [-sql select_statement]

       <src_datasource> <dst_filename>

 

Any ideas?  If so, please respond to this email address.  Thanks.
