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?
Regards, Rositsa

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?
