Hi all, Also about the Geo module and supporting formats, some libraries, like the newer versions of GeoTools (version 8.0 or newer), supports other formats of Geo Spatial data, that would be way a to expand this module in the future. Right now I am checking it to see how it works :) Regards

Dear David, thanks for your request. Yes, one of our members (Masoumeh) is in fact working on an implementation of the Geo Module (for GML2), and it may get finished in Januar or February. It will closely resemble Zorba’s implementation, and we think about proposing some updates to the official EX

Hi Basex-ers I am new to the list but have been working with basex for a few weeks now. We are using basex to search ISO 19115 geospatial metadata. The full text search is simple and works better than any of the existing purpose built catalog tools we have worked with so far. I am very intere

Hi all All my talks about indexing were based on (my) assumption, that efficient querying (what is the core case I am looking forward) requires existence of an index. Frankly speaking - I am mostly interested in querying - if it goes fast enough without any index, I do not mind the difference. My

Dear Ingo, Rosi has already summarized the main challenge: there are lots of different approaches that revolve around spatial querying. Did you already have a quick look at the EXPath module, and do you think it might be helpful in your scenario? I cannot give details when we will actually be abl

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 Met

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? http://exist-db.org/extensions.html#module_spatial
