[mapguide-users] RE: Navigator(Zoom Slider), Virtual Earth Zoom, open layers in Basic web layout

[Fraser Burgess]

Thanks Chris

 

Your answers for 1 and 3 give me the info I needed to know... Much
appreciated.

 

For Item 2

I played with the zoom levels option and tried 15 through 25..  Seems
like 20 is the maximum and there is no impact when you set it over 20.
If I set it anywhere under 20 then Google cannot zoom in to its max zoom
level as you would expect.   So I thought there may be a conflict
between Google and Virtual Earth so I removed the Google layers and only
worked with MSVE.  Despite playing with the zoom level option with just
the MSVE layers here I cannot zoom in to the max in MSVE.

Zoom, open layers in Basic web layout

 

I can provide some vague answers - hopefully someone else on the list
can provide more detail...

 

For item 1....

 

The Navigator is contained by the <div> with the id "Navigator". The
location of the div is controlled by settings in the CSS file...

 

#Navigator {

  right: 10px;

  top: 10px;

  display: block;

}

 

This is easy to spot in jxtheme.uncompressed.css, but the slate template
uses the compressed version (jxtheme.css) for maximum performance. If
you find this section in the compressed file:

 

#Navigator{right:10px;top:10px;display:block;}

 

You should be able to modify the location.

 

For Item 2...

 

I think the maximum number of zoom levels is about 20, and I'm not sure
what happens if you try to set it too high - it might use the maximum
value or it might revert to the default. There is also an issue that you
can set the number of levels on either the layer or the map object and
I'm not sure which one takes precedence. 

 

For item 3...

 

The Google/MSVE support is based upon the use of OpenLayers, which is
used by Fusion, but not by the Basic viewer, so it would be a LOT of
work to add it into a basic layout. It is also possible to use
OpenLayers all by itself outside of either viewer, but you then lose all
the buttons etc from the web  layouts.

 

One other thing to consider - the trunk version of Fusion supports
Google/VE layers simply by modifying the flexible web layout definition.
It might be worth looking into that.

 

Chris.

open layers in Basic web layout

 

Hi,

 

I have a few questions and was hoping to get some suggestions from the
list.  I'm running the MapGuide Enterprise 2010 :

 

1.       How can I move the Navigator(zoom slider) control in the fusion
slate viewer?  Currently it is fixed at the top right and I would like
to move it to the top left.

 

2.       Using the usual  'addGoogleStuff' code I've added with Virtual
Earth base layers along with Google base layers in the Slate fusion
template.   I am unable to zoom in past about 1:5000 when I use the
Virtual Earth base layers.  I believe there should still be 2 more zoom
levels I should be able to achieve with virtual earth base layers.  The
numZoomLevels option is set to 30 which I think is far more than what is
offered in MSVE.  Using Google Earth as my base I can zoom right in.
Any idea how I can zoom in closer to the MSVE base layers 

 

3.       So I've been somewhat successful at adding the 'addgooglestuff'
code to a flexible fusion layout.  Is it possible to do the same thing
in a Basic Ajax Layout?  If so what file should I be adding code to use
the google / MSVE as a base in my Basic Web Layout.  Is t here any
sample pages out there that have done this?

 

Thanks

 

Fraser
