mapfish.lib.filters.spatial¶

class mapfish.lib.filters.spatial.Spatial(type, geom_column, **kwargs)¶

Spatial filter.

type

the type of filter to create. Possible values are Spatial.BOX, Spatial.WITHIN, and Spatial.GEOMETRY.

geom_column

the Column object corresponding to the geometry column.

**kwargs

epsg

the EPSG code of the lon, lat or box values, see below.

for Spatial.BOX filter:

box

a list of coordinates representing the bounding box [xmin, ymin, xmax, ymax]

tolerance

the tolerance around the box of the search region, is expressed in the units associated with the projection system of the lon/lat coordinates.

for Spatial.WITHIN filter:

lon

the x coordinate of the center of the search region, the projection system of that coordinate can be specified with the epsg key.

lat

the y coordinate of the center of the search region, the projection system of that coordinate can be specified with the epsg key.

tolerance

the tolerance around the center of the search region, is expressed in the units associated with the projection system of the lon/lat coordinates.

for Spatial.GEOMETRY filter:

geometry

the geometry to search in, formatted in a GeoJSON string

tolerance

the tolerance around the geometry of the search region, is expressed in the units associated with the projection system of the lon/lat coordinates.
