Is there a public Web Map Tiling Service (WMTS) available? Also, I fail to see how restful WMTS is any harder to maintain than XYZ, seeing as both are a direct one-to-one mapping from url to resource? |

Is there a public Web Map Tiling Service (WMTS) available? If you implement WMTS with a restful interface, then the resulting urls look exactly like slippy map ones, eg, server/service/style/layer/scale/row/col.png. However, slippy maps forces you to use spherical mercator and fixed zoom levels, which means easier maths and no config, but at a cost of less flexibility. If you want to use a more accurate projected coordinate system, such as one a national mapping agency might use, and you want to define scale levels such as 1:250, 1:500, 1:1250, etc, then WMTS allows this -- sure, XML config is a pain, but you have to define your service somehow. |

Display two layers with OpenLayers at once You probably need to explicity add the proj4js library. OpenLayers only has native support for common formats like 900913. See the example here: openlayers.org/dev/examples/using-proj4js.html Also, see the userguide on the proj4js page to see how it is done. trac.osgeo.org/proj4js |

Nearest Neighbor problem in Postgis 2.0 using GIST Index (<-> function) You can use g1.gid>g2.gid in the where clause, which will reduce the number of distance calculations you have to do. Unfortunately, until the <-> operator works without constants, we won't see much of speed improvement in this kind of query. |

How can I convert an excel file with x, y columns to a shapefile? I suppose you could write something in excel vba to rearrange your columns first so that date, x, y were always the first 3 columns. Without some kind of column naming conventions, I think it would be difficult to completely automate what you have in mind, though. |
