[Cartoweb-users] Geostatistics with Postgres

[Albert Casanovas]

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
