Anthony,
I have done a similar operation, but using ArcSDE (sounds like a case for
ArcSDE, with those sizes).
Then I created batch-files that added the separate coverages to an SDE
layer, and using ArcInfo Workstation (the command-line) or the ArcSDE
command-line tools (supplied and installed with ArcSDE).

| 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) ?
|
| 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.
|
| 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.
|
| Anthony
