Hi Brad,
within my editor i have a group function, where the user can select
several polygons in order to built his group
grouping means collecting the polygons to a multipolygon and giving this
multipolygon a new set of attributes
this means, that all the polygon specific attributes will be lost,or
after degrouping the multipolygon the attributes will have the same value
for example:
p1->a=12;p2->a=24 results in mp->a=24, after degrouping p1->a=24,p2->a=24
database:
as grouping polygons will result in a multipolygon, the column where to
store this data has to be of type "multipolygon"
if polygons will be stored in the same database, they have to be
multipolygons with a single polygon
my database backend in geoServer was a Postgis-DB but had to be changed
to a shapefile
maybe someone knows if we can store polygons and mutlipolygons in the
same table?
Cheers Carsten

Yves,
This sounds interesting. I have a need to select a group or collection
of polygons from a user who just clicks the polygons they need. Then I
need to aggregate all the geometries into a single object and also
aggregate the numeric attributes. Then to insert the new geometry into
the database as a WFS-T transaction. So far my OL application can get
all the polygons and all the attributes with WFS but have not got
software to aggregate the geometries. Would you have the javascript
software to do this?
Cheers, Brad…

Hi Yves,
thank you for your answer, i hope other people also had some fun with
this nice tool!
What ist your impresiion of it? Could it be usable?
Are there any other testers or has someone else a feedback (either
negative or positive) for me?
English UI: Our development-focus is set on german farmers, so there
is no need to use an english one!
But if there is a big demand for it, i will do it, or better let it do:-)
thx Carsten

Hi list,
my work on a GeoEditor is nearly completely done.
Features:
* using Openlayers for geometric operations, only joining and
splitting is done by a JTS-Java-Backend
* using WFS-T with a GeoServer(Shapefile as backend) for storing
the changes
* using SLD and handmade Java-BackEnd for storing LayerStyles
* using dojo for editing styles.
Restrictions:
* only german front-end
Proof-of-concept:
* https://143.93.78.98/geoEditor2/editor.html, use "demo" and no
password for login
Thx Carsten

Hi folks,
i am working on a small geo-editor for an agricultural project in
rhine-palatinat/germany, visit http://www.agroconnect.de for more
information.
Upto now my editor has the following features:
* new polygon, plain OL
* edit polgon, plain OL
* delete polygon, plain OL
* union polygon, OL with a javaserver in the backend
Coming feaures:
* split polygon into 2 elements, OL with server backend
* group polygons
At the moment i am hanging a bit with the split-feature.
My idea is
1. select polygon
2. select first point/vertix as starting point
3. select second point as ending point
4. do split
5. remove polygon and add the new ones
Step 4 will be done on serverside,but could also be done on
clientside.
Any ideas how to realize steps 1-3. Should i use several controls
(Select and Modify) or
should i subclass Control.ModifyFeature ?
Any hints will be appreciated.
