[Qgis-user] PostGIS 2 SHP
Hi fellows, I am loading a postgis Layer and then saving it to shapefile. Job gets done. BUT, data type character varying, or character, is always set to 255 CHAR in the shapefile. Therefore, my dbf ends up being a huge table. Is this some bug or I am simply doing something wrong ? Any thoughts appreciated Ricardo The exporting procedure (save as) of qgis do this. But if you use og2ogr (from gdal) to export from postgres to shapefile the string field was exactly the needed. I test with the trunk version of gdal.

[Qgis-user] Plugin to read raster color value

[Qgis-user] Re:autostyles for PostGIS
Hi all. If we save a file in the same folder and with the same name as a vector layer, that style is used automagically every time the layer is opened (which is good). How could one do the same for a PostGIS layer? All the best, and thanks for any suggestion. It is a good question. But it is a bit complex. Because a table is not like a file. Infact if for a shapefile (a file) the style is in another file. Maintaining the same paradigm, for a table the style must be in another table. But for a style-file is more simple use it. Is sufficient to decide of use another extension. (.sty for example) For a table, the style cannot be another table with the same name. So the choice of others products was to use a unique table (with a fixed name), usable for all the tables of the schema. This is quite simple conceptually, but is heavy as choice because need to establish that in a postgis-enabled schema must be available a specific table with a specific name. In ArcSDE for example, esri use a set of tables gdb_* , one of they is for the rendering. However is qgis could have an autostyle in a table for postgres/postgis (and spatialite also) , it will be a great feature.

[Qgis-user] RE: Shapefile structure viewer and editor plugin
am searching for a plugin that calculates the area and perimeter of polygons of shapefiles and other vector layers e.g. spatialite I think there is none at the moment, if I am not mistaken. However, you can get the area and perimeter of the layer using fTools. Vector- Geometry tools - Export / Add Geometry Columns Hi noly, you can even use the area button in the calculator. You add a new columns and fill it with the button area in the calculator. Unfortunately is missing the perimeter button. But perhaps it could be a simple add ?

[Qgis-user] Compile using Python 2.7
Hi, I'm try-ing to compile the qgis system. using the Ming/Msys compiler under windows 7. To do this I follow the hints available to this link: http://www.qgis.org/wiki/Installation_Guide But when I retrive the QT And python I see was available some more new version (qt 4.6.3 and python 2.7). And there was not more available the original version (qt 4.4) suggested in the manual So I decide to try using this new versions. After this, I download SIP and PyQT4.

[Qgis-user] ArcSDE
There almost 2 types of arcsde layers. The single Layers and the geodatabases's layers. The first is quite simple because every dataset (table) is isolated from others datasets (tables). The second is more complex because use all the GDB tables to understand the GIS constraints between all the tables (datasets). (ps: the geodatabase is not a relational DB so it don't know and don't use foreign-key and so on.) - This second format is supported only from arceditor and arcinfo level of arcgis family products (about 20K$) - After this there is another physical level of difference. ArcSDE can use the esri-native format . I don't remenber how it is called, but remenber is some like a binary archived in a blob field. Or it can use DB native formats like Oracle SDO_Geometry and so on. I don't know is gvsig can support all this differences perhaps it support the single-layers structure when used with some DB format like oracle sdo-geometry ? Andrea. UDig is the only open source Desktop GIS that can do this. I've done this, and can confirm that it works for viewing/editing (normally $10k of ESRI software is required to do just this). It just takes some setting up and getting the correct versions and JARs together. I've had less luck with OGR ArcSDE, since it has a lack of community support to properly build and QAQC the libraries (e.g., http://trac.osgeo.org/osgeo4w/ticket/42) and only works with ArcSDE 9.1 and 9.2 (not 9.3 or 10.0). -Mike ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
