Surprise, it's not about OGC....
I've got a massive dataset I am working with. Currently in coverage format,
100+ folders with lots of subfolders, etc. each with it's requisite coverage
files. I'm trying to bring these into ArcView8.x either as shapefiles or in
a personal geodatabase. Unless there is a compelling reason to go one way
or the other, I am indifferent on whether shapefile or geodatabase is the
result. I know I can always create the geodatabase later from shapefiles,
etc. The real problems I am having is that since these are scattered
through all these folders and subfolders, is there an easy, automated way to
bring them all in at once (for example, "UTM grid" is one of the coverages).
Is there a way to "import" all the UTM coverages into ArcView 8.x in one
operation (simultaneously merging them all into a single shapefile would be
good too) ?=20=20
What I mean by easy and automated is trying to avoid what I am doing now,
which is "adding data" and having the navigate (cumbersome and time
consuming) all 100+ folders and subfolders to bring the data in. (This
results in a large number of layers all named the same, and then I have to
use the geoprocessing wizard to merge them all, etc. to get a single layer
name UTM). I have read the Help documentation on the processes of importing
and even looked at batch mode, but it all really requires me to visit each
individual folder/subfolder (or type in the full path), and then still, then
just creates lots and lots of layers (shapefiles or geodatabase features)
called UTM1, UTM2, UTM3, etc. and this doesn't seem to really save me much
time and effort.=20=20
Also, anyone know what technical limits are in ArcView8.x in terms of layer
size ? I've got a 2Gb+ layer that crashes ArcMap every time I try to load
it, so I have to split it up into 3-4 parts, which is a drag. My system has
2Gb SDRAM, 1.2Ghz processor, WinXP (latest SP), lots of swap memory too, and
it kills my system. Incidentally, is this managed better in a geodatabase
or made worse ? Thanks.=20=20
