I would vote for the best between all samples for best clarity of the same kind.  With a button option to switch between Aerial photos to Hyrography, or any other types.

Subject: WMS poll

 

I'd like to solicit people's opinions about the orthoimagery WMS we have been providing.  I currently have two more services ready to go, the 1-meter black-and-white orthos (the original "DOQs" from USGS), and 2008 data for Augusta and Manchester.

What I want to know is how people feel about having many mapping services in a single URL, vs. having them broken out into separate URLs (i.e. one URL per web service).

My strategy was to have very few URLs, to make it easy for people to remember the few that are out there, and put as many services into each URL as possible.  That it makes it simpler to manage on our side and simpler for the user to keep the WMS connections straight on their application.

BUT there is a downside, and that is different applications support WMS in different ways.  For example, if I put more than 10 layers in a WMS, then ArcGIS will only turn the first 10 'on' by default.  The user is left to click the others 'on' or 'off'.  And in other software such as Google Earth or QGIS, the user will have to sort through an increasingly long list of layers to pick the one(s) they want.

So if you have an opinion one way or the other I'd appreciate hearing it.  I anticipate that next week will bring completion of the 2005-2007 York County orthos and the 2007 Cumberland County orthos the following week.  I'd like to get all of these up as soon as possible.
