[mapguide-users] Lat Long Display Issue/Bug

[Kori Maleski]

Thanks Alain,

Here is the real bug then:

Map is projected.
Washington State Plane NAD27 North (ft)

Data is geographic WGS 84

I have a ZoomToView function that reads from a point database with LatLong
columns.

I use the MGProjection/Factory etc. to translate these point positions to
the proper projection.

Send the new coordinates to the ZoomToView.

Works like a charm.


Now:

I want to pass my selection in XML to the SetSelectionXML.
I create an MGSelection object querying a LatLong Parcel Layer in the
Projected Map.

Passes it...

It then selects my feature and zooms to a LatLong position on the XY
projected map (somewhere far far away.

So. 2 Questions:

Does the SetSelectionXML function zoom to its selection automatically?

Why is it zooming to latlong coordinates when the map is projected?



I believe this is a serious bug, unless I am out to lunch somehow...

Hi Kori,

This is a bug that only affects the display of the coordinates. The
order of the parameters in the ZoomToView function has always the same
meaning, regardless of the display settings, so do not switch the Lat
and Lon values in the call to this API.

Hi All,

I have a map that I am displaying in Washington State Plane NAD27 North
(ft)
projection and the DWF viewer is switching the Lat for Lon in the
coordinate
display.  

Anyone else see this?  Does this mean we have to switch them for the
ZoomToView function as well?

Cheers,
