[Cartoweb-users] Geostatistics with Postgres

[Albert Casanovas]

Hi ,

Two questions:

1. Do you think that to adapt the plugin geostat to get the DATA from a SQL connection instead of a DBF file is only necessary to edit the map file?

2. How can pass a variable from the ServerGeostat.php to the Map file for a SELECT .. WHERE id=x ?

Thanks a lot,
Albert

  Hi Albert,

  So far, the whichShapes() method belongs to the LayerObj (http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class/classes/layerobj).

    Thanks Oliver,

    I am working in the adaptation of the geostat plugin to get the information from through SQL queries. According to what I have analyzed, the modifications needed to be done are:

    - Configuration file geostat.ini with the information of the database for the connection.

    - Parsing of the geostat.ini file in the method getConfLayers() of the server/ServerGeostat.php file

    - Distribution for the requested layer and attribute in the method getDistribFromSpatialData($layer, $attrib) of the server/ServerGeostat.php file

    At the moment I am in this third step and I would like to ask about the whichShapes method in this line

    $msLayer->whichShapes($rect);

    I cannot find where is this is any method implemented in any library of the mapObject.


    Do you have any suggestion about doing this implementation?

    Best Regards,
    Albert

        Hi,

        I would to know if there is posible to get the values from a database instead a .dbf file in the demoGeostat demo like is doing in the example:

        www.cartoweb.org/demos/demoGeostat.php

        Which modifications should I do to the pluguin in order to allow it to take the values from a database?
        Can I have the map in a shapefile and its information in the database?


        Thanks a lot,
        Albert Casanovas
