Hi all,
A draft tutorial has been completed on use of projections in MapServer:
https://geographika.github.io/tutorial/quickstart/projections.html
Comments and feedback welcome. This relates to
http://mapserver.org/development/rfc/ms-rfc-115.html
There are a couple of things I came across that are still unclear to me
relating to extents.
* Setting the EXTENT for a map has no effect when accessing via WMS,
apart from the BoundingBox of the GetCapabilities metadata. Data is
not restricted/limited.Not setting this leaves the MAP level
BoundingBox extent as -1,-1,-1,-1. Should the MAP EXTENT have any
other effects?
* The help for LAYER EXTENT states "In most cases you will not need to
specify this, but it can be used to avoid the speed cost of having
MapServer compute the extents of the data" - however all BoundingBox
extents for each layer are automatically calculated from the source
data in the WMS GetCapabilities request. I presume this could become
quite slow with more and more layers. Is it/should it be recommended
to manually set these (either with wms_extent in the LAYER METADATA
or using LAYER EXTENT)?
Thanks for any clarifications on the above.
Regards,
Seth
