Hi All,

 

Intersection problem:

 

I have an application performs a query on a polygon layer with a point -
using intersection with the spatialfilter.

 

The problem is this:

 

The polygon originated from a shapefile - loaded as SDF via studio.

The single polygon feature originally was 2 distinct polygons dissolved
together via ArcMap.

 

The intersection works only on one of the polygons, and fails to return
a feature reader at all when within the other polygon.

 

This fails in both code execution and as a GeFeatureInfo WMS request in
the same manner.

 

Has anyone encountered this?

Has anyone worked around?

 

Is it better to explode the feature?  I require the geometery from each
part to do a highlight.

 

Is there an issue with how a shapefile multipolygon is converted to SDF?

Or is this an isse with the SelectFeatures functionality?

 

 

 

Cheers,

 

 

Kori Maleski

In the studio preview, it fails as well.

Using the select tool, clicking on one polygon will highlight/select the
entirety, while clicking on the other will yield no highlight/select.

Re: [mapguide-users] Polygons and Intersection Problem

2009-01-15 Thread shreepadr 

One suggestion would be to repair the geometry of the polygons in ArcMap
If you go to tool box there is a tool called repair geometry, run that and
recreate the sdf file 
Second option is bring the shape file into AutoCAD and then create SDF from
there 
I had this issue before and when I repaired the geometry in ArcMap it worked
fine


Thank
Shreepad

RE: [mapguide-users] Polygons and Intersection Problem

2009-01-15 Thread Mark Pendergraft 
I queried the feature programmatically (as a SDF) and tried to assign it
to a mgMultiPolygon and it didn't fly.  It did work as a mgPolygon
though.

So, the problem seems to be that the geometry is being stored as a
polygon instead of a multipolygon.  I have features in my map that
aren't connected and I'm able to select them with no problem, but they
are multipolygons.  This must have something to do with the conversion
process in ArcMap or in MapGuide Studio.  I don't have ArcMap so I can't
comment on what is going on in that arena.  Your guess is as good as
mine on whether this is an ArcMap issue or a MapGuide Studio issue.

 

However, if you load the data as a SHP file (uncheck convert to SDF in
MapGuide Studio) and then view the layer in Studio, you can select
either side.  So perhaps the solution is to just use the SHP file in
your map instead of converting it to SDF.

 

Hope that helps

Re: [mapguide-users] Polygons and Intersection Problem

2009-01-15 Thread Kori Maleski 
Thanks Mark,

That clarifies what I am seeing.

GetGeometryType() only yields MgPolygon instead of MgMultiPolygon, so it is
the conversion to SDF where the Shapefile geometry is lost/changed.

The Repair Geometry in ArcMap was already completed and does not affect nor
remedy the issue.


To workaround the issue (in SDF format):

I have to explode the Polygon into 2 Pieces.
Then I have to do a spatial filter to retrieve the common ID.
Then requery to get both of the desired geometries.


I will test my application to see if utilizing the shape file without
converting behaves properly with my code and the WMS.


Cheers and thanks,


Kori Maleski

Re: [mapguide-users] Polygons and Intersection Problem

2009-01-15 Thread Kori Maleski 
If the polygons are loaded as a Shapefile without the SDF conversion, the
spatialfilter query will work on both polygons and the GetFeatureInfo WMS
call will work as well.

The spatialfilter returns a MgPolygon where the first polygon is the
ExteriorRing and the second is the InteriorRing.


So this scenario will work fine without converting to SDF.
