Hi,
my application using MS SQL-Server as DBMS for the data.
In a table 'tbl_Plants' I'm storing the XY coordinate of my entity that are
Radio/TV emitter (points).
Usually my local application export the data in .txt file and ArcView import
the text file and create the Events Layer to display the georeferenced
features.
Now I'm starting to develop intranet application to manage the data with ASP
pages, and represented the data with MapServer.
Just for the sample, I've create the static shape file of the DB entity
using ArcView.
Using MAP mode for MapServer in <img... > tag I can show the correct map and
point in the right position.
For the background I'm using TIFF raster layers.
NOW, when the application change the entity coordinate via ASP page, but now
the DB and the shape file ARE NOT linked and the shape file report the old
position of the entity.
This will be a distributed application an the remote user must be-able to
change the entity coordinate and see the new position immediately.
Q.:
How can I update the shape file on-the-fly without use manually ArcView to
regenerate the correct shape file?
