Hello friends - MapGuide 1.2 / PHP / Postgres\PostGIS / Windows environment.
I have a table with many lines in it. I'd like to be able to retrieve one record of line information, create a new layer on the fly, populate it with that line information, save to repository and go. I have been able to perform this operation with Point data using the development guide as a basis. There is something in the dev guide / samples for creating a line, but it seems like it won't work for my situation for a few reasons. 1) My underlying table has bunches of lines in it. I need to detect the user input and show only the line they are interested in. 2) Filtering against PostGIS doesn't seem to work; otherwise I'd just grab the existing layer, filter out everything except the one line I need to see, push to the repository, and go. I've already got the lines defined; but I can't figure out how to take the geometry from the right row and populate it into a new feature for serving up at runtime. If need be, I can also retrieve all of the points that comprise the line; I saw something in the dev guide that seemed to indicate I could define aline segment by going from point to point, creating lines. I suppose it would be possible to get every point ordered, and create a line from 1 - 2, 2-3, 3-4 .... Is this my only choice? Can anyone help? Thanks! -brian -- View this message in context: http://www.nabble.com/Creating-a-new-line-layer-at-run-time-tf4064562s16610.html#a11548595 Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
