[postgis-users] pgsql2shp - No GID variable
Hi all, When using the pgsql2shp the gid column is not included. I even tried typing a select gid AS g_id to include it as a different column name, but this did not work. My syntax: pgsql2shp -f pgfinal2008.shp -h localhost -u user -P pass postgis public.pgfinal2008 SELECT *, gid as g_id FROM pgfinal2008 Any ideas how i manage to extract the gid column from my tables?

Re: [postgis-users] pgsql2shp - No GID variable
Hi, I tried that, but at first it did not seem to work when loading the shapefile into ArcGIS. However, it seems that i had to restart ArcGIS to make it update the attribute table for the file. Now -r works. Thanks. Andreas 2010/10/26 Mark Cave-Ayland mark.cave-ayl...@siriusit.co.uk Andreas Forø Tollefsen wrote: Hi all, When using the pgsql2shp the gid column is not included.

Re: [postgis-users] WKT Raster Error
I already saw the two first lines: c:\wktraster_pg84\bin\gdal2wktraster.py:645: DeprecationWarning: integer argumen t expected, got float hexstr = binascii.hexlify(struct.pack(fmt_little, data)).upper() But it didn't not prevent the script to create the sql file properly. I guess this is related to the Numpy version. Maybe try to use an older version. It should work with the pipe.

I take it this used to work for you - gdal2wtraster.py. Which version of gdal are you running under python? FWIW -- we don't run it like that -- we run with the -o output file swithin. I'm not sure the way you are running it works or not So try c:\Python25\python c:\wktraster_pg84\bin\gdal2wktraster.py -r c:\prio_grid\source\forest\fcworld.img -t forest -s 4326 -I -o C:\prio_grid\source\gpw\forest.sql and see if you have any better luck. Alternatively you can try the new postgis raster packaged with PostGIS 2.0 and use the gdal2raster.py. It has some minor fixes in it. Although its in 2.0, at the moment the rtpostgis*.dll is still a separate binary and doesn't YET have any direct dependency on postgis-2.0.dll (and has a few more functions that the old wktraster project is missing. So you can grab it from there and use with your PostGIS 1.5/1.4 or whatever install. This MAY CHANGE when PostGIS 2.0 finally comes out. We'll also be releasing a new windows binaries of PostGIS 2.0 in the next day or so. The dll in that build will change from rtpostgis.dll to rtpostgis-2.0.dll, but will still be pretty much the same functionality.

At least for the Z value you could use st_translate to adjust the value. On Tue, Oct 26, 2010 at 4:24 PM, Rhys A.D.

Re: [postgis-users] Postgres Polygon to Postgis Geometry
Hi Wagner, I'm not sure what you mean by geo and non-geo .. you mean georeferenced, like longitude/latitude? For points, you can keep thing binary and just use ST_MakePoint(x,y). And to assign a coordinate system, use it with ST_SetSRID: SELECT ST_SetSRID(ST_MakePoint(p[0], p[1]), 4326) from ( select point '(-123.112793, 49.246293)' as p ) as foo; I'm not sure how to do similar binary conversions for path and polygon, or other types. You might have to cast to text, and wrangle it into some form of WKT, then pass it to ST_SetSRID(text, integer) to make a geometry object for PostGIS. -Mike On 26 October 2010 18:17, Wagner Santos wagner.des...@gmail.com wrote: I created a Postgis Geometry from Postgres Polygon converting them from string and using linefromtext to create a geometry but this information isn't geo.

Re: [postgis-users] Postgres Polygon to Postgis Geometry
Mike, Yes, I mean georeferenced (sorry for my English). I made a cast to text and converted to postgis geometry, but I couldn't use ST_SetSRID. I would like to tranfer a polygon to correct position. I have a Polygon BOX(743295.3125 7182512.5,744414.75 7183817.5) and I like to transfer it to BOX(-54.515022277832 -25.4530487060547,-54.5029907226562 -25.4447135925293). I tried ST_Affine but I don't know the correct parameters, I tried ST_Scale but I had the same problem. My idea was transform and set srid.

Re: [postgis-users] Postgres Polygon to Postgis Geometry
Ah, you are looking for this:
http://postgis.refractions.net/docs/ST_Transform.html
So you need to cast your object as a polygon, set the SRID to your
projected coordinate system (I'm just guessing SRID=29181 for your
example http://spatialreference.org/ref/epsg/29181/ .. look up the
SRID for your original data). Then it can be transformed into long/lat
coords:
SELECT ST_Transform(ST_SetSRID('BOX(743295.3125 7182512.5,744414.75
7183817.5)'::box2d::geometry, 29181), 4326);
