Peter,
I can think of a few reasons, one for example, I have a geologic map that has
only USGS quads for position reference. I also have a shapefile that has
county outlines and another that has the PLSS land survey townships and section
lines. I need a GeoTiff because one of the
first? Might a direct read
be faster?
And Even, please excuse my ignorance, but what is gdb? I really would like
to do the profiling.

Luke,
Thank you for this suggestion. This too the access times from 15-20 seconds
down to 1 to 3 seconds. The majority of the time seems to be spent on the
initial read of the vrt as subsequent piped locations after the first are
returned sub-second. For my current application, this should
one massive file (in addition to the individual tiles,
which could be archived), this might work for your use case.
Thanks,
Dan

Jukka,
No matter the endpoint the user uses to access the data, behind the scenes,
there must be fast pixel access, correct? Or are you saying that at WFS would
do it quickly out of the box?

. If it's the intersection, then there's potential for
improvement.
seems an intersection with a set of
polys first would be quick

I have a set of 55,501 bil files in a single directory. They are DEMS data
that cover the US in 7.5 minute tiles. I would like to randomly access
elevations at a given lat/lon's from the whole dataset. I created a vrt file
from the directory of bil files, and have been able to access

It will provide you with all the details of the CRS in question

All,
Working in C#... I have need for EPSG:4418. Per http://www.epsg-registry.org/
this is the code for ProjectedCRS [NAD27 / BLM 18N (ftUS)]. This code does
not seem to be in the GDAL/OGR/Prog4 database in FWTools2.4.7. Executing the
line:
var i = src.ImportFromEPSG(4418);
This call
available in the
last FWTools build or not.
I will note that deleted shapes aren't completely deleted
until you repack the file. There should be some details
on repacking on the driver page.

All,
Using the C# dll's that come in Frank's FWTools, is it possible to add, delete
and modify records in a Shapefile, or do I need to create a new Shapefile with
the changes?

Does OgrInfo report the actual extents of the geometries in a ShapeFile or just
the extents reported in the header of the ShapeFile?
