How to create a topologically correct dataset in PostGIS (with GRASS)? You might want to look at PostGIS topology: postgis.refractions.net/docs/Topology.html as PostGIS in itself has no concept of topology |

How to calculate the bounding box by a given center and scale in Android? the only thing you need to know about the projection is its units, OpenLayers uses the OpenLayers.INCHES_PER_UNIT[units] array in Utils.js. web mercator uses meters as unit, which means 39.37 instead of 4374754 to calculate resolution |

How to calculate the bounding box by a given center and scale in Android? Yes, that is correct. As long as your users doesn't expect to use the map in the same fashion as a paper map (i.e measuring on it) any value can be used (and I think most mapping libraries use 72 or 96) |

How to calculate the bounding box by a given center and scale in Android? Android, are you using the Google Maps API or just plain displaying an image? I Would also recommend against using an unprojected coordinate system to display your map, as it will look heavily distorted. |

How to calculate the bounding box by a given center and scale in Android? What projection are your map in? Web Mercator? Or do you display a unprojected map in lat/lon? And the size of your viewport, is that in pixels? Is the scale in piels? Do you use any mapping framework/library that might have a function for this? |

Display list of OpenLayers Features which are currently visible on screen Aha, seems OpenLayers has got guite a few new features lately. I guess my solution is akin to setting boundsOnly to true on onScreen. But either way, you have to somehow loop through all features to check them. Glad to help! |

How to use cql_filter in OpenLayers.Control.WMSGetFeatureInfo? Yes, that's the point. Changes to the CQL of a layer does not automagically reflect themselves to the WMSGetFeatureInfo control. So, you have to apply the new CQL filter to the GetFeatureControl as well |
