[MapQuery] defaults on the map

[Steven Ottens]

Hi all,

Playing around with map.defaults I realized that the map options pretty much directly map to the OpenLayers.Map properties. Obviously we are not going to wrap them all but there are a few we probably want to at least document; the ones which have defaults in OpenLayer that are commonly used to setup WMS/TMS/WMTS layers:

projection: "EPSG:4326",   
units: 'degrees',
numZoomLevels: 16,
maxResolution: 1.40625,
this.maxExtent = new OpenLayers.Bounds(-180, -90, 180, 90);

-projection can be mapped 1to1; proper name and sane values
-units can be mapped 1to1; proper name and sane values
-numZoomlevels can be mapped 1to1 decent name and sane value
-maxResolution is not a very nice one, I propose that if it is not set we try to calculate it from maxExtent since it is a difficult concept and tends to depend on maxExtent and tilesize anyway and as such do not document this one as a public property
-maxExtent needs to be wrapped; it currently takes a openlayers.bounds object and we most likely need the mapExtent within MapQuery for instance to calculate the maxResolution


What are your thoughts?
