[mapguide-dev] PHP pages for describing a feature source RFC

[Andy Morsell]

OK.  That's better functionality then.  Unfortunately, Studio doesn't work
that way.  If you last viewed a layer in split or preview mode, then open a
newly created default layer, it will attempt to draw the extents in the
preview window without prompting the user.  Anyway, it would still be nice
if you could warn users somehow before they try to display large feature
sources - but would not be a critical piece of functionality at this point.

The graphical display only shows the geometric properties for the given
feature class after the user selects the "show details" link beside the
geometric property. In a way, this is similar to how you described the
default view to be set up in Edit mode for Studio. It does not force the
user to view the map unless he/she chooses to.

 

Thanks,

I like the overall functionality and think that it will be very useful.  One
thing to watch out for, however, is graphically displaying the extents of a
large feature source.  This is not always desirable since it can cause a
strain on MGOS server and take excessively long to return the map view.  The
same problem already exists in Studio when you view a default layer
definition in split or preview mode (one of the reasons I would like to have
the ability in Studio to specify that my default view is always Edit mode).
So, perhaps you could query the feature source to determine the number of
features and then tell the user "This feature source is very large, are you
sure you want to preview it?"

I have just posted a draft of the RFC for "PHP pages for describing a
feature source" in MGOS to the following location:

 

http://wiki.osgeo.org/index.php/MapGuide_RFC_8_-_PHP_pages_for_describing_a_
feature_source

 

Please take a look, and post any feedback to this group.

 

Thanks,
