comment Web Mapping Services from Europe besides OSM
I don't think Google uses NAVTEQ for much anymore; They moved towards TeleAtlas (and local providers) and recently have moved towards their own.

comment Downloading Google Maps municipal geometry
The data Google has is vastly better than any of the publicly available data. There is no free equivalent to the data they have.

comment What components does OpenLayers.Strategy.BBOX require for compilation?
culebron: the OpenLayers build tools are really supposed to do this for you. This might indicate a bug in OpenLayers that it doesn't; you might consider reporting it as an issue.

comment Ovi Maps in OpenLayers?
Note that using an XYZ layer directly is likely a violation of the Nokia Maps Terms of Service, just like almost all commercial web map providers. The ovi-base.js was a proof of concept, but is not a supported or encouraged way of doing things.

comment Can we use GeoExt Freely?
Ext is free for commercial use, so long as you can adhere to the terms of the GPL. If you can not (Or don't want to figure out if you can), you can purchase commercial licenses.

comment How can we improve the OpenLayers documentation?
For the record, very few OpenLayers developers use stackoverflow compared to the number of users and developers who are available on the mailing list. In general, I see the same dozen people on Stack overflow -- but the OpenLayers mailing lists have more than 1000 people signed up to them. So, SO isn't always your best option to get correct answers quickly.

comment OpenLayers weird problem with GoogleMaps base layer and WMS overlay
Upvoted, since this one had more information, but the key component is in the update; you need to do what the OL docs say.

comment POI Datasets for North America
TelaAtlas doesn't have (as far as I know) a public API to get access to their data. Nokia doesn't have a public API to get to their data. OSM doesn't have an interesting set of POI data -- they have some limited, spotty coverage, like GeoNames, but it's not at all a source that you can use if you want to actually have a comprehensive set of POIs. bit.ly/1anyma has more information.

comment POI Datasets for North America
In general, Geonames does not have an interesting set of POI data. (For example, a worldwide search for "Eye Care" will find a dozen results in Iowa, but none in other states...) They may have a smattering of user-submitted data, and perhaps even some limited data in other areas from various sources -- NGA's GeoNames dataset certainly includes some things in this vein -- but it's nowhere near complete enough to consider as a resource to use in the way most people want a "POI database".

comment Trouble getting metacarta to work with qgis?
The GetCapabilities document for the VMap0 map has never been maintained correctly, and I don't have any real intention of starting now.

comment TomTom OpenLayers zoom effects
I'll note that on neither of my browsers (Safari on Mac or Firefox on Mac) do I get any kind of animated zooming effect on that website; this kind of problem is the reason the animated zooming was never enabled. In addition, it regularly crashed some browsers. In the end, it was just too risky. That said, with newer webkit + moz transform code for pinching and zooming, there is sufficient support in OpenLayers to explore animated zooming behavior which is hardware accelerated in the browser without complex DOM manipulations, and I expect one of our developers may show an interest in that soon.

comment Quality of free geodata compared to commercial sources
You mean, "Why is OSM better in many places than Google Maps?" Because asking why Google Maps might be better, given the hundreds of millions of dollars invested by their data partners over the past, oh, say, 25 years (NAVTEQ at least), compared to a 5 year old volunteer project done with practically no funding, seems a bit disingenuous.

comment How to get US Highway exit geocodes using Google maps API or through some other means?
Note that using the Google geocoding API for bulk geocoding like this, and storing the data, may be a violation of the terms of service. In addition to the technical restriction (5000 geocodes a day), and social restriction on maps (can only be used on Google Maps, nothing else), I think there's also an additional social restriction that limits how long you can store geocodes for that you should probably look at.

comment Trouble getting metacarta to work with qgis?
That's not the URL for the WMS. It's vmap0.tiles.osgeo.org/wms/vmap0. Presumably he's past that though, because he is getting the capabilities, but maybe qgis handles that redirect, but won't handle a redirect for the tiles.

comment What is this “brown spot” in Google maps?
I agree this is almost certainly a processing artifact, and not a real thing.

comment Data Source: Address ranges for every block in NYC
In general, address data does not exist in OSM in large quantities, especially in the US, so I would be very surprised if this data exists in OSM in a way that would apply to a significant portion of New York.

comment OpenStreetMap content in commercial applications
2.0 vs. 3.0 is minor legal clarifications. The core of the license remains the same. ("Unported" is because there are now legal-text variations suitable for many different countries; the 'unported' is their newest term for the 'generic' worldwide one.)

comment OpenLayers with my own OSM data server
The OSM coordinates are in meters, so you'll have to set the center in projected meters. See docs.openlayers.org/library/… .

comment Can I collect Seismic data with an array of cell phones?
In general, the accuracy of cell phone-based accelerometers are pretty low. If you have a specific device in mind, people might be able to tell you if the accelerometer is going to be able to do what you want; WP7 is on relatively few devices afaik, so I assume that you already have one in mind.

comment is there any free software to create a mapserver that can be installed directly in a subdomain without a server install?
MapServer is a single binary that can be put in place with no further 'installation' needed. However, the fact that you're asking about "PHP or JS" means to me that you're probably in a more limited hosting situation that doesn't allow you to use most software -- instead, you probably need PHP. You should probably either mention a host (so people can provide specific information) or, if PHP is all you're comfortable with, just limit the question to PHP rather than attempting to be more broad.
