I work for MapBox, where I work on a few mapping projects. I write over at macwright.org.

comment Reverse geocoding Nominatim results
It's unclear what you're asking. Have you succeeded in installing Nominatim? Is it working, or not working, and if not, what error are you seeing?

comment Is dynamically generating Choropleth maps a solved problem?
Had to flag that comment, since it's a self-link but not indicated as such.

comment Is it possible to redesign OpenStreetMaps tiles?
Create a map in your account, click 'Publish', click 'MapBox.js', copy the map id and then in OpenLayers-land, OpenLayers.Layer.XYZ('MapBox', 'http://a.tiles.mapbox.com/v3/[mapid]/${z}/${y}/${x}.png')

comment Projection for Tracking a Vehicle
Is this for an online system or print? Within a 100 mile radius, you don't exactly hit terrible distortion unless these cars are in the Arctic. Why not just use Spherical Mercator and standard web maps? If it's for print and you need rulers to work, disregard this comment.

comment Database for offline slippy map tiles
Near-zero and spotty browser support plus low size limits. Try for yourself.

Post your entire code. You aren't initializing map as the right name or at the right time.

comment Database for offline slippy map tiles
What you're looking to do isn't possible without a native component. It's probably time to renegotiate.

comment Open source Cloud GIS
GDAL supports read/write FileGDB via a closed-source SDK. Not as bad as other formats, but still terrible.

comment How do I stop event propagation with rightclick on Leaflet marker?
This is for a DOM event. If Leaflet wraps events, use event.originalEvent.

comment Creating Mobile web mapping application
(to be clear: those apply only to usage with MapBox tiles. You can use the SDK with other sources of tiles, which have their own terms of service(s?), which have similar provisions.

comment geoserver support to proxy other tiling services?
This is the best answer to the question, but should be taken with the recommendation that you should never do this on external services that you do not control - at the very least it's a performance nightmare, and more typically it's against terms of service and will result in your service being suspended.

comment Displaying UTFGrids with Mapnik and TileStache
> It sounds like your tile-offset position is constantly being determined on mouse movement and that position corresponds to the json grid's rows/columns. Is that how the look-up for the utf characters is done? Yes - offsets based on the pixel position into a big array of strings. The encoding is just made to compress well with gzip. Right now I've only worked on glower for Modest Maps - at that point there was no UTFGrid support in OpenLayers.

comment What is the purpose of having a separate Layer property for sphericalMercator?
You can do either, but often layers will have more or fewer zoom levels. As soon as there's a "every layer has X but this layer has Y" relationship, it gets harder to track. I'd rather be explicit about configuration, but it's essentially a judgment call.

comment What is the purpose of having a separate Layer property for sphericalMercator?
Okay, to be more clear: it isn't necessary - you can do one and/or the other. As far as specifying projection/settings in the map object or layer object, OL will check the layer object for a projection and then go to the projection on the map object. It's recommended to set all projection & zoom-level type settings on layers, so that you don't have configuration inheritance.

Nope. You might want to try CartoDB, but you should know that making things dynamic and making things performant are opposing goals.

comment Is there a paid service for accessing a PostGIS/OSM DB
This is the only answer that actually addresses the PostGIS part. Though, to be clear - CartoDB exposes a web API to PostGIS. There aren't any services that allow a socket-style connection to a server 'in the cloud'.
