memory issue when trying to buffer/union large dataset using postgis Thanks Paul. Your solution worked (almost) perfectly. It is a bit slow to run on my server (I think I still have work to do to optimise memory usage, it now never ramps up!) but it does the job! I had to remove the last step (groupedfinal) because for some reason it crashes (Error message: GEOSUnaryUnion: St9bad_alloc - even though I call ST_Union not ST_UnaryUnion, and even if I ST_Dump() the multipolygons before the final union to simplify the geometries). However I managed to run that step separately in arcgis so that is not a big issue. |

memory issue when trying to buffer/union large dataset using postgis Thanks. This looks pretty simple indeed. I will fall back to this if my attempts are doing it through a sql loop fail (quite likely given my level!) |

memory issue when trying to buffer/union large dataset using postgis Thanks for your help. I do have 1 attribute I could use in a group by clause, but I suspect it won't help much (only 2 values in the field, and the split is 90% / 10%). If spliting the multipolygon in individual polygons using ST_Dump or similar would help I can definitely do it, but from what I can tell this would happen after the massive multigeometry is created anyway so not sure it would help? also, my geometries are not in lat-long, so if I want to use geohash I believe I need to convert the coordinates first... is there an alternative? |

Is it possible to reference data using mapped network drives instead of UNC path in arcgis server services? Thanks for your answer Unicoletti, however I don't think I made myself clear. I don't see how what you describe can help me with my problem: I already know that the services can access network shares using the unc path, and I have sucessfully created gis services using that method. what I wanted to know was if there was a way to make the service understand things like Z:\ == \\myserver\myshare, just like a normal user could. |

Well I think ideally I would be happy not to use to them but historically we (my company) have been using mapped drives as a abstraction layer to allow mxds to be copied across various offices/servers (without breaking the links, as long as long as the relevant datasets were copied as well and using the same folder structure). If I could make this work it would work well with our existing file structure. |
