gisserver.parsers.gml package

Additional parsing logic for GML values.

Most GML elements are parsed through GeoDjango by using the GEOSGeometry element.

gisserver.parsers.gml.AbstractGeometry

alias of GM_Object

class gisserver.parsers.gml.GEOSGMLGeometry(srs: CRS, geos_data: GEOSGeometry)

Bases: GM_Object

Convert the incoming GML into a Django GEOSGeometry. This tag parses all <gml:...> geometry elements within the query.

__init__(srs: CRS, geos_data: GEOSGeometry) → None

build_rhs(compiler: CompiledQuery)

Required function to implement. This allows using the value to be used in a binary operator.

classmethod from_bbox(bbox_value: str)

Parse the bounding box from an input string.

It can either be 4 coordinates, or 4 coordinates with a special reference system.

classmethod from_xml(element: NSElement)

Push the whole <gml:…> element into the GEOS parser. This avoids having to support the whole GEOS logic.

GML is a complex beast with many different forms for the same thing: http://erouault.blogspot.com/2014/04/gml-madness.html

geos_data: GEOSGeometry

property json

srs: CRS

property wkt: str

Render the Geometry as well-known text

class gisserver.parsers.gml.GM_Envelope

Bases: AstNode

Abstract base classes for the GML envelope, regardless of their version.

class gisserver.parsers.gml.GM_Object

Bases: AstNode

Abstract base classes for all GML objects, regardless of their version.

build_rhs(compiler: CompiledQuery)

Required function to implement. This allows using the value to be used in a binary operator.

class gisserver.parsers.gml.TM_Object

Bases: AstNode

Abstract base classes for temporal GML objects, regardless of their version.

See ISO 19108 TM_Object (see D.2.5.2 and ISO 19108:2002, 5.2.2)

gisserver.parsers.gml.find_gml_nodes(element: NSElement) → list[NSElement]

Find all <gml:...> elements in a node. This selects all GML elements, including GML 2.1 tags.

gisserver.parsers.gml.parse_gml(text: str | bytes) → GM_Object | GM_Envelope | TM_Object

Parse an XML <gml:…> string.

gisserver.parsers.gml.parse_gml_node(element: NSElement) → GM_Object | GM_Envelope | TM_Object

Parse the GML element.
