Whilst the ESRI comment is currently strictly true, spatialite is now supported by FME (as of the current release of earlier this year), so ESRI support may come in the Data Interoperability extension (which is FME) in due course - perhaps when 9.4 is released next year. Peter Matt Wilkie wro

Matt, (Sorry for the duplicate email, I initially replied only to you and not the list.) In my experience the open source community rarely, if ever, defines a thing before creating it. What usually happens is that somebody (whether an individual or small group) builds somethings that works, or

Simon, it's clear you have a great deal of experience in this area. If it were up to you to chart out a course for an open source spatial vector format that trancends the current limitations of shape, gml, etc. what would you advise? Perhaps all that is missing is an architectural plan. The on

Simon, I agree a long way with you. But how about a solution? I think enough smart people are involved in OSGeo, it should be possible to get them together and create a fully Open-Source fast vector format. I'm not one of those but I'm willing to help with the requirements, implementation and test

The need for a new vector file format has been discussed many times with no action initiated by the open source community on what to do. ESRI has said they will do so, but it's been several years since they first announced it and when it is finally is released there is no guarantee it will be u

Jukka, it depends upon what your desired result is. If you just want to replicate maps, the answer might differ from seeking to work with the information contained within the maps. Either way, if your data is going to exceed 6GB, you probably ought to be looking to one of the DBMS soluti
