[mapguide-users] I need advice on grid data gdal/vrt and mapguide

[Jamo]

Say I have some grid data I can retreive in the form of

x,y,z

where x and y are true GDA MGA-56 coordinates and z is a positive or
negative decimal value....

How would I take this data and display it in mapguide? So far I have tried
using Saga to produce grid files for them then prepare a vrt file and show
them using that, however I'm finding setting it up to accept transparency
difficult (where there is no data -99999 the grid should not display
anything)

None of the GridLayerDefinition settings in the Layerdefinition seem to work
?

Some example data:
*VRT file 4 bands RGB and true height.*
Can I just supply mapguide the sdat file and style completely in mapguide?


*Grid Layer Definition:*


Any help would be much appreciated, despite what my signature says this is
for Mapguide 2.4 stable release on windows server 2008 R2 SP1 64bit

I have managed to remove all hillshade settings and surface settings and
render greyscale surface however I still can't get the transparency to
work... I can load the vrt in saga and it displays

Cheers
Adam
