[Geoserver-devel] Data editing in Geoserver: Just confirming type of edit

GeoServer GeoServer Developer

Hi all,

New to Geoserver and new to list. On the geoserver
website it states that it supports WFS-T, now, can I
physically edit SHP files through Mapserver/Geoserver
or will the data need to be inserted into a spatial
database first and then edited?

My hope is to create a series of SHP files (only) and
allow a user to edit both the geometry and attribute
data.

Regards
Ben Crane

Yes, editing of shapefiles works just fine.

allow a user to edit both the geometry and attribute
data.
  

You got it.

We highly recommend putting the data in a spatial db, but if there's only one user editing at a time then shape files should work ok. They just don't have the native support of transactions, so the code is just written on top of them. With shp2pgsql and pgsql2shp utilities you can easily go in and out of PostGIS, which is free, and pretty easy to set up.

best regards,

Chris

Chris,

We have thought of that, but we will have possibly
hundreds of users wanting to access user specific shp
files. No user will ever look at any other shape files
than the ones they're permitted to do, so there will
never be a case of 2 users accessing and editing the
same file. If that occurs, we've messed up the
permissions badly.

We thought storing native SHP files in directories
allocated to each user would enable us to just upload
once a day any shape files processed for a user and
from there the user can edit, display the data as they
see fit. We felt a SD might just complicate it and
perhaps slow access for other users since we will have
hundreds of users potentially and ALL their spatial
data stored as well.

We just felt it was an easier setup to maintain using
PHP/Perl. Any additional thoughts would be most
welcome.

GeoServer should be able to handle it then.

We thought storing native SHP files in directories

Well, I would say that databases are built precisely to simplify such things like many users accessing it at once, but if you find the shapefile approache easier on your end I believe it should work. I just don't have quite the same confidence in it that I do in a spatial db.

We just felt it was an easier setup to maintain using
PHP/Perl. Any additional thoughts would be most

I think it's up to you. Your use case seems like it should work fine with GeoServer and shapefiles.

best regards,

Chris
