Re: [postgis-users] More details for errors
Hi again! Well, this is always the same problem, if I do linemerge(union()), I have to force multi to prevent errors. Then, simplifying to linestring seems to consume resources. On way, would to do a view which determine if the union would lead to a multi or a linestring. But I don't know how to achieve this. I have no idea either if this would also be greedy on resources. Denis On 03/27/2012 05:43 PM, Nicolas Ribot wrote: Yes, it is 2.0 http://postgis.refractions.net/documentation/manual-svn/ST_CollectionHomogenize.html Well, I am turning around the problem... I have to do a cast, as I used ST_Multi(ST_LineMerge(ST_Union(wkb_geometry)))::geometry(MultiLineString,xxx) in the first view to prevent errors of unconnected lines. Right now the best solution I have is to let the view being unusable, and another view to report errors. This is not very satisfying as if a problem occurs, I cannot use my view until I fix the geometric errors. Basically, I need to compute a view with a LineMerge returning LineString (i.e. leaving away features leading to MultiLineString) and another view returning IDs of features leading to MULTI. I thought about using ST_Touches but it only uses two geometries and I can have more in the LineMerge. No idea what to look for... Thanks for your help. I could go deeper in the problem! Greetings I would then create 3 views: One doing the actual computation (linemerge(Union)), then one view where st_numgeometries(the_geom) = 1, and one view where st_numgeometries(the_geom) 1. nicolas ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
[postgis-users] adding JTS geometries to a PostGIS database
Hello, I'm using the Java Topology Suite (JTS) and I want to store geometries with PostGIS. How do I do that? What works: statement = conn.prepareStatement(INSERT INTO sometable (geofield) values (?)); org.postgis.PGgeometry m = new org.postgis.PGgeometry(myJtsGeometry.toText()); statement.setObject(1, m); statement.execute(); What I would prefer: statement.setObject(1, myJtsGeometry); statement.execute(); According to http://postgis.refractions.net/documentation/javadoc/org/postgis/DriverWrapper.html, the DriverWrapper is supposed to take care of the wrapping. However, even when I add DriverWrapper.addGISTypes80((org.postgresql.PGConnection)conn); I get the error message Can't infer the SQL type to use for an instance of com.vividsolutions.jts.geom.MultiPolygon. Use setObject() with an explicit Types value to specify the type to use. I am connecting to jdbc:postgresql_postGIS://localhost:5432/ The driver class is org.postgis.DriverWrapper What am I missing? Or is the first, working way the right one? Seems like a waste of time to me, converting binary - text - binary...

Re: [postgis-users] LinearReferencing: measure vertex of linestring?
Create a ticket describing the calibration, that's useful info and
would be a good utility for LRS users for a future version.
P.
2012/3/28 Andrés Maneiro amane...@icarto.es:
Hello people,
I'm reviewing what postgis is able to do in terms of Linear Referencing. As
fas as I could see, to calibrate a linestring there is only the method
ST_AddMeasure:
http://www.postgis.org/docs/ST_AddMeasure.html
So, as stated in the example, the operation will create a route like:
SELECT ST_AsEWKT(ST_AddMeasure(
ST_GeomFromEWKT('LINESTRING(1 0, 2 0, 4 0)'),1,4)) As ewelev;
ewelev
LINESTRINGM(1 0 1,2 0 2,4 0 4)
What I'm wondering is if somehow I could calibrate the vertex of the
linestring, having as a result, for example, this route:
LINESTRINGM(1 0 1,2 0 *1.7*,4 0 4)
The project I'm working on is related to road management, and it's very
common that the ratio between a route's length and its measures is not
constant. So, my doubt goes: is it somehow possible to create a route in
postgis where the measure and the distance are not directly related?
(For those who know how ArcGIS dynamic segmentation works, what I'd like
to achive is something similar to calibrate a route using points [1]).
Let me know if I explain myself properly.
best,
Andrés

Hello, I tried all hints from this thread and that: http://postgis.refractions.net/pipermail/postgis-users/2012-March/033111.html but it is still impossible to install PostGIS 2.0 on Windows XP. I also copied libproj-0.dll in bin folder - it didn't help. Do you have any other suggestion ? Piotr. W dniu 2012-03-27 04:26, Paragon Corporation pisze: PROJSO settings shouldn't be necessary anymore because libproj.dll is not used. I upgraded the install to use proj 4.8.0 so the dll is now libproj-0.dll which is what gdal assumes by default. It's possible I missed a dll and my tests systems already had them -- make sure you have libproj-0.dll in your bin folder. I think if postgis is in use it won't be able to copy the dll so you will probably need to shut down your service / restart and then run the copy script.

Also you know (or maybe someone else knows) is it possible to accomplish this in PostGIS 1.5 ? Hi, Yes it is.

[postgis-users] Making Tiger shapefiles routable
Has a set of standard queries been developed to make Tiger shapefiles routable? It would need to eliminate gaps and ensure that all end nodes and intersecting nodes corresponded with each other. image001.gif___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users

This might be better asked in the pgRouting list, but I'll address it here and cc that list. I have loaded tiger data into pgrouting and you do not need to mess with the end points, just run the just process it like any shapefile and it will work for want it is worth. The issue with Tiger is that the data is not really suitable for routing, I was using it for drivetime analysis where the results are approximate and that worked fine for my use cases. Here are some of the problems with Tiger data: * segments are not flagged for oneway streets * there is no zlevel information at intersections ( so it will generate routes like drive to an overpass and turn right onto the underpass ) * the road classifications do not allow you to set the average speed for a road class very accurately, although this is minor compared to the first two. -Steve W ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
Re: [postgis-users] POSTGIS 2.0 on WIn
We'll be releasing a 2.0.0rc1 soon probably in the next day or so. Regarding why it's still not working 1) Did you run one of the batch scripts. 2) Can you verify you have the following files in your bin folder a) libgdal-1.dll b) libgeos_c-1.dll c) libgeos-3-3-3dev.dll d) libproj-0.dll (that I assume you already checked) 3) and you have postgis-2.0.dll and rtpostgis-2.0.dll in your lib folder (Note these must go in the lib folder not the bin folder) Let us know if it still doesn't work with those. We haven't recently tested on windows xp so there might be some dependency that exists on windows 2008 and windows 7 (which are the two platforms we've been testing mostly with) that we don't have in place that is needed by xp. We'll try that tomorrow on an xp box if you are still having issues.
