[mapserver-users] OGR Support for TIGER 2000 Data?

[Ed McNierney]

Dawn breaks on Marblehead (as they say around here...)

Rob -

Thanks!  I have no problems at all and my OGRINFO tests work, and
MapServer works.

Jeff threw me off the trail by naming the directory in which he stored
the TGR25001.* files "TGR25001".  As a result, I thought he was simply
specifying the root name of the files - and that OGR would simply look
for TGR25001.* in the same directory as specified.  Instead, he was
specifying the name of the DIRECTORY holding all the TGR25001.* files.

I'm happy - everything works.  Thanks everyone for the help!  Jeff, you
might want to update your excellent example pages to make this
distinction clearer.

	- Ed

Okay, this was a bit confusing to me but I now see what Jeff is saying.
OGR must look at the entire directory of raw data to open any of the
layers instead of a single .RT* file. I thought Jeff just meant that the
full path to the file must be specified, but instead just the directory
where the layers reside must be specified.

For example, my TIGER data is in:

/usr/local/mapdata/TIGER_2000/WA/53063/

In this directory I have files TGR53063.RT1 through TGR53063.RTZ.

Instead of calling ogrinfo as: 

ogrinfo /usr/local/mapdata/TIGER_2000/WA/53063/TGR53063.RT1

Try calling as:

ogrinfo /usr/local/mapdata/TIGER_2000/WA/53063

So OGR can look at the entire data structure. Works for me on this end
now. Thanks Jeff!
