Mapnik 0.7.0 Release
|
||||
--------------------
|
||||
|
||||
- Gdal Plugin: Add support for Gdal overviews, enabling fast loading of > 1GB rasters (#54)
|
||||
(Packaged from r____)
|
||||
|
||||
- PostGIS: Added an optional 'geometry_table' parameter. This is used by Mapnik to look up metadata in the
|
||||
geometry_columns and calculate extents (when the 'geometry_field' and 'srid' parameters are not supplied).
|
||||
If 'geometry_table' is not specified Mapnik will attempt to determine the name of the table to query based
|
||||
on parsing the 'table' parameter, which may fail for complex queries with more than one 'from' keyword.
|
||||
Using this parameter should allow for existing metadata and table indexes to be used while opening the door
|
||||
to much more complicated subqueries being passed within the 'table' parameter without failing (#260, #426).
|
||||
- Core: Fixed linking to external libagg (r1297,r1299)
|
||||
|
||||
- Core: Completed full support for PPC (Big endian) architectures (r1352 -> r1357)
|
||||
|
||||
- Gdal Plugin: Added support for Gdal overviews, enabling fast loading of > 1GB rasters (#54)
|
||||
|
||||
* Use the gdal_addo tools to add overviews to existing GDAL datasets
|
||||
|
||||
- PostGIS: Added an optional 'geometry_table' parameter. The 'geometry_table' used by Mapnik to look up
|
||||
metadata in the geometry_columns and calculate extents (when the 'geometry_field' and 'srid' parameters
|
||||
are not supplied). If 'geometry_table' is not specified Mapnik will attempt to determine the name of the
|
||||

|

failing (#260, #426).
|
||||
|
||||
- PostGIS Plugin: Added optional 'geometry_field' and 'srid' parameters. If specified these will allow
|
||||
Mapnik to skip several queries to try to determine these values dynamically, and can be helpful to avoid
|
||||
possible query failures during metadata lookup with complex subqueries as discussed in #260 and #436, but
|
||||
also solvable by specifying the 'geometry_table' parameter.
|
||||
also solvable by specifying the 'geometry_table' parameter. (r1300,#376)

- PostGIS: Added an optional 'extent_from_subquery' parameter that when true (and the 'extent' parameter is
|
||||
- PostGIS: Added an optional 'extent_from_subquery' parameter that when true (while the 'extent' parameter is
|
||||
not provided and 'estimate_extent' is false) will direct Mapnik to calculate the extent upon the exact table
|
||||
or sql provided in the 'table' parameter. If a sub-select is used for the table parameter then this will,
|
||||
in cases where the subquery limits results, provide a faster and more accurate layer extent. It will have
|
||||
no effect if the 'table' parameter is simply an existing table. This parameter is false by default.

||||
- PostGIS Plugin: Added 'bbox' token substitution ability in sql query string. This opens the door for various

complex queries that may aggregate geometries to be kept fast by allowing proper placement of the bbox

query to be used by indexes. (r1292) (#415)

* Pass the bbox token inside a subquery like: !bbox!

* e.g. (Select ST_Union(geom) as geom from table where ST_Intersects(geometry,!bbox!)) as map
|
||||
|
||||
- PostGIS Plugin: Added 'scale_denominator' substitution ability in sql query string (#415/#465)
|
||||
|
||||
- PostGIS Plugin: Added support for quoted table names to allow for tables with characters that postgres
|
||||
requires quoting for like dashes (r1454) (#393)
|
||||
* Pass the scale_denominator token inside a subquery like: !scale_denominator!

* e.g. (Select * from table where field_value > !scale_denominator!) as map
|

|
||||
- PostGIS Plugin: Added support for quoted table names (r1454) (#393)
|

- PostGIS: Add a 'persist_connection' option (default true), that when false will release
|

the idle psql connection after datasource goes out of scope (r1337) (#433,#434)
