Would be nice to have KML support in addition to GML, but I suppose there are tools to support GML use with Google Maps, for example: http://www.dyasdesigns.com/geoxml/ MarkLogic supports multiple formats: The Geo module provides support for geospatial queries using GML, KML, GeoRSS/Simple, or Metacarta Geospatial markup. Sure would be exciting to have geospatial in BaseX! Eric On Fri, Jan 6, 2012 at 10:55 AM, Rositsa Shadura < rositsa.shadura@uni-konstanz.de> wrote:
Hi Ingo, hi all,
until now we at BaseX have not discussed the implementation of a geospatial API. However, I would like to ask you what is actually your requirement: a module which provides functions for querying spatial data or a feature for indexing such data or both? :) I ask because the replies from Jan and Erdal referred to indexes, while this from Eric was more about a module for querying such data. Currently there is a specification provided by EXPath[1] which defines an extensive geospatial API. The only implementation of this specification is, as far as I know, this provided by Zorba[2]. The ones offerred by eXist[3] and MarkLogic[4] do not follow it or provide just a subset of the functions in it. Do you think that an implementation of the EXPath geospatial API would be useful for you?

Hi,
Our company evaluates BaseX for our project.
A new requirement is to show spatial data with a geographic information system.
Are there any plans for a spatial xquery module for querying GML like the (experimental) module in eXist?
Regards, Ingo
