[Geomoose-users] raster specs/speed of GeoMOOSE demo

[Fischer, Brian]

Hi Zack,
 
I assume you are talking about the aerial photo WMS source and USGS topo
quad WMS source that is in the state demo application.  That WMS was
published by LMIC
(http://www.lmic.state.mn.us/chouse/wms_image_server_description.html).
I don't know all the details of the architecture, but I agree it is the
faster I have ever seen.  I do know it is built with MySQL and some C
programming code.  There has been some talk about trying to make this
architecture available, but I don't know where that is.  I'm not sure if
anyone from LMIC is on this list or not, but they may be able to speak
more about it.  Hope this helps,
Brian

I noticed, probably everyone noticed, that the GeoMOOSE map example on
their home page is SUPER fast, as fast as GoogleMaps or GoogleEarth,
even with images turned on.  It's faster than the USGS Earth explorer
and all their interfaces.

 

Does anyone know how the imagery on the GeoMOOSE site is optimized for
the fastest delivery?  What format, tiling sizes, overviews (pyramids)
does it have?  Is there an optimum size of image size itself?  Is there
some special caching commands in MapServer it needs to go the fastest?

 

My own MapServer/WMS layers don't come up that fast even when serving
from my localhost to my local browser, and I have a dual processor Xeon,
so I really would like to get the secrets.

 

            -Zack
