Application of MapGuide Open Source

[Anonymous]

Hi all,

If anyone's interested in an example of how flexible the new MapGuide
Open Source (and MapGuide Enterprise eventually) is, I have made public
an experimental service that uses this application to serve City of
Nanaimo vector data to Google Earth dynamically.

If you have Google Earth installed, go to this page and click on the
nanaimoMaster link:

http://earth.nanaimo.ca/data.html

As you zoom in, you will be able to see park points and parcel polygons,
both of which link to PHP reports. Using the rich API (and with the
assistance of an example script provided by Bob Bray at Autodesk) we
serve different data depending on the view scale.

These features are generated on-the-fly from data stored in SDF+ format.
As you move around, Google Earth sends PHP the bounding coordinates of
the current window. Once you are within a certain distance of the
ground, these coordinates are used as a filter to a MGOS spatial query
that accesses the SDF+ files through an FDO provider, and returns a
result set of features in the current window. These features are then
iterated and sent to Google Earth in KML format.

You could as easily use this methodology to build an AJAX server that
takes the current Google Local/Yahoo Maps/MSN Live Local bounding box
and generates placemarks for you. Of course, I'm sure that the next
version's HTML viewer will be good enough that there will be no desire
to do this. 🙂

VERY COOL Jason!!!
Extremely interesting concepts...

The future is 'wide open' 😉

hay jason,
good job.

my question - could we come in contact - we are interested in the "solution" you made...
we have an internal map system up and running - MapGuide
Open Source (archaeology of the greater berlin area, germany) and we are interested to publish dynamically our data into google earth...

could you send me the "receipt" or give me your e-mail-contact to ask you some questions...would be great...

with best regards from frosty germany

Nice job! How can you catch Google Earth's PHP? Do you use Enterprise Edition of Google Earth?

I'm not interacting directly with Google Earth's services. I'm
providing data through a mechanism that is built into the KML data
format, called network links. These allow you to provide data on a
dynamic basis.

Hey great job

I am working on implementing a mapguide opensource install and am running into problems with the php install on my server. I have been using the latest install guide, and the virtual directories etc are created but I get a php error, when the site is accessed? A recipe that works right about now , would be wonderful Thanks in advance

Hi James,

I would encourage you to search for the answer in the MapGuide Open
Source "users" mailing list archives.

https://mapguide.osgeo.org/servlets/SearchList?listName=users

or

http://www.nabble.com/OSGeo-MapGuide-f14845.html

If you can't find your answer, sign up for an osgeo.org account, join
the mapguide users mailing list, and send the list an email with a more
detailed description of your configuration and the error you're seeing.
