Re: [postgis-users] PostGIS Installation Issues
Hello, Thanks very much for the help. ldconfig fixed the problem right away, even attempted a second fresh install and was able to get everything working the first time through. Thanks very much for the help.

Re: [postgis-users] Need a "polygon box" of a table instead of the bounding box that returns extent function
Well, it works like a charm!
But I still need some advise. The query generates a polygon and I use astext
to get readable output. Now I create a new table that will contain a name
and the geometry result of the query. I want to use something like:
INSERT INTO boundaries ( the_geom, the_name ) VALUES (SELECT
ST_ConvexHull(ST_Collect(the_geom)) as the_geom from my_street_table),
'mytablename');
This can't work but I don't know how to do it better.
By now I first returned the polygon as text and then did the following:
INSERT INTO boundaries ( the_geom, the_name ) VALUES
(ST_GeomFromText('POLYGON((-58.8714168974345
-34.5696042275729,-58.9620017725354 ...))'), 'mytablename');
With this and pgsql2shp I generated a shapefile for the boundary. I could
draw the streets (original shapefile) and the boundary both together and
they match perfect!
Please excuse me if I am making a silly question but I'm a newbie.
Thanks in advance

Re: [postgis-users] PostGIS Installation Issues
For reasons beyond me, I know that after installing recent builds of PostGIS on Ubuntu, you are required to also run: sudo ldconfig I've contemplated making a trac ticket for it, but I'm not exactly sure what the problem is or if it can be directly addressed in the "make install" target (or if it was, is it now broken). See if that command works for you. -Mike On 4 May 2010 13:30, yoda2nd wrote: > I tried your commands and got the same result. Below is the error > message from postgis.sql.

Re: [postgis-users] PostGIS Installation Issues
I tried your commands and got the same result. Below is the error message from postgis.sql. I have checked to make sure that postgis-1.5.so was there and it is. I have been unable to find libgeos_c.so with the same directory. However both Geos and Proj libraries compiled and installed without any known issues. PostGIS config picked them up correctly during ./configure. psql:/gis/source_code/postgis-1.5.1/postgis/postgis.sql:59: ERROR: could not load library "/usr/lib/postgresql/8.4/lib/postgis-1.5.so": libgeos_c.so.1: cannot open shared object file: No such file or directory Thanks for the help Mike.

[postgis-users] WGS84 Representation
Hey, I'm trying to store WGS84 coordinates as points. A sample is: 5043.7922;N; 01324.4940;E; So, if I store this coordinates with POINT( 5043.7922 01324.4940), the column contains: 0101202E90A0F831024C40C6E1CCAFE6602840 In addition, I discovered that google uses the WGS84 coordinate system too, but with a different representation. According to http://www.tma.dk/gps/#converttodec, I converted 5043.7922;N; 01324.4940;E; to: 56.01715 12.18926 I tried to visualize both representations on google maps, but just the decimal r. is displayed properly. There is also an other representation degree, minutes, seconds. I'm confused since all three representations seem to belong to the same WGS84 coordinate system. Am I right? So, what is the reason for having multiple representation of the same coordinate system. Would you suggest to persist the decimal representation? Or do even all representations end up in one internal representation as mentioned above? Thanks for your help, unfortunately I just started with the exiting GIS topic. Thanks.

Hi Maria. If you need multiple restrictions for a given edge then you have to add multiple records for that edge each with a separate restriction http://pgrouting.postlbs.org/wiki/ShootingStar Fred.

Hi, I'm trying to do a shooting_star calculation following this example: http://www.davidgis.fr/blog/index.php?2008/07/24/349-shooting-star-usage-example-with-turn-restriction But I think that it has a bug when reading the rule.
