some questions about geoJSON, I'm no specialist.. does GeoJson support<br>
spatial indexes? Isn't it a bit more space consuming with all the xml tags<br>
inside.. Does it support compression?<br></blockquote><div><br>Geojson is not a XML format, but you are right, the colums names are repeated for each features :<br><a href="https://en.wikipedia.org/wiki/GeoJSON">https://en.wikipedia.org/wiki/GeoJSON</a><br>
<a href="http://www.geojson.org/">http://www.geojson.org/</a><br><br>I have not yet search how we could build a spatial index from a GeoJSON, but we surely could find a way.<br>It supports GZIP compression, as it is a simple text file, and we could use it as QGIS can now handle zipped files.<br>

A remark on the-fly, when MITAB will be modified to support edition, you<br>
could have a file format that does what you want. I know some people are<br>
willing to fund developpement to do it.. Not open source, but efficient<br>
format.<br></blockquote><div><br><br>You are right, but I am looking for an open-source format. :) <br><br>Michael<br> </div></div></div>
