[Cartoweb-users] Geostat error going from close zoom to FullExtent

Mon Aug 4 02:37:08 EDT 2008

Hi
postgis report "check your .map file" so I would say something is wrong somehow with the inner query, probably linked to bad/wrong parameters in the layer connection DATA string.
if you do select the_geom, oid, id, talhao, surf from edit_poly directly into postgres, what do you get ?

regards
Oliver

  Hi Damien,

  Thanks to you. I have done the update. In this project I also do have a layer for edition of Polygons from the example of demoEdit and after doing your modification I got a conflict with this layer, this is the message:

  Failure  
  Class : SoapFaultWrapperMessage : MapServer error: Error in msDrawMap(): Failed to draw layer named 'EDITPOLY'.
  Error in prepare_database(): Error executing POSTGIS DECLARE (the actual query) statement: 'DECLARE mycursor BINARY CURSOR FOR SELECT asbinary(force_collection(force_2d(the_geom)),'NDR'),oid::text from (select the_geom, oid, id, talhao, surf from edit_poly) as foo WHERE the_geom && setSRID('BOX3D(931968.170091 -2617023.93743308,1351878.170091 -2343764.69412691)'::BOX3D, -1 )' 

  Postgresql reports the error as 'ERROR:  cursor "mycursor" already exists
  '

  More Help:

  Error with POSTGIS data variable. You specified 'check your .map file'.
  Standard ways of specifiying are : 
  (1) 'geometry_column from geometry_table' 
  (2) 'geometry_column from (sub query) as foo using unique column name using SRID=srid#' 

  Make sure you put in the 'using unique  column name' and 'using SRID=#' clauses in.

  For more help, please see http://postgis.refractions.net/documentation/

  Do you have any idea of what can be happening??

    Hello,

    Thanks for finding out these issues.

    I just fixed the choroplethDataFromCurrentBoundingBox = true issue in CVS. If you're using it, you can either update your CW3 or remove line 271 in ClientGeostat.php

    The following patch fixes the "blank shapes" issue. It will be committed by the end of the day.

    Regards,
    Damien

      Hi,

      In the demoGeostat.php, seems to lack some parts of the image without painting when doing a Full Extent, we have tested it on the one in the web site (http://www.cartoweb.org/demos/demoGeostat.php) and the problem is the same, you have to follow the following sequence:

      1. Do a close zoom and from there apply a Choropleth.
      2. Do zoom out or Full extent and some of the regions will appear white.

      We checked the parameter choroplethDataFromCurrentBoundingBox which is set to false, so apparently is correct. 
      Another problem was when we change this parameter to true, produces an error:

      1
