#4536 closed defect (fixed) does not generate valid KML (OGC KML 2.2)

Reported by: tylere Owned by: hobu
Priority: normal Milestone: 1.10.0
Component: Utilities Version: svn-trunk
Severity: normal Keywords: gdal2tiles KML


The script does not currently generate KML documents that are valid against the current OGC standard schema ( In particular:

  • the default XML namespace is incorrect
  • the <name> element should not be capitalized
  • the <description> element should not be capitalized
  • within a <Region> element, the <LatLonAltBox> element should occur before the <Lod> element

A patch correcting these issues is attached.

Note that Google Earth will silently accept many invalid KML files if the default settings are used. Select Tools->Options->General->KML Error Handling->"Show prompts for all error" to be notified of invalid KML.

Are you sure that the patch is correct as such ? I see you are inverting the order of some elements in the string, but you should also likely adapt the order of the values that will substitute the %d and similar stuff.

In particular, I believe that line 1631 should be changed like this ( argsminlodpixels moved after cwest) :

	""" % (cz, cx, cy, args['tileformat'], cnorth, csouth, ceast, cwest, args['minlodpixels'], url, cz, cx, cy)

You are correct. Even though it is now creating valid KML, the element attributes are not correct (since I did not reorder the format string parameters). I will correct and add/replace the current patch.
