[OSGeo-Discuss] online open source polygon mapping, like OSM?

Thu Aug 4 02:59:50 PDT 2011

Hej Nitin I'll risk my credibillty on a comment. I grasp little of GIS, but I've spent a lot of attention on visualizing data and 'painting on the screen'. I've got an impression that time-animations belong to a next generation GIS, but don't take my word for it. I expect that the code-changes needed to animate a 2d polygon lies very deep in the code structure. Ok, say I have what you have on your pc .. I would look for the polygon-data. Is it accessible? I know of one set of polygon-data, and that's the esri shapefile format. I've been working on accessing that format through code, but I'm not all there yet. Next question: how/where are the changes of data? I mean, do you have ie two sets as a 'before' and an 'after', or do you have a time-dependant algorithm that can be used on the initial data to propagate it forward (probably not). How is your setup on that front?The 'painting-mashinery' of your pc may read directly on the data, so there could be problems on syncronisation if you start to write to the same data - I could imagine that this is where the real problems are, becourse the transmission from the data to the screen may need to be redirected to somewhere else (to the changed data) or wrapped up in a thread-safe way. That's a problem that's been solved before, but probably not without altering the original code .. it's on the edge of my experience.That said, I'm very little acquainted with any gis-tools, so don't take my comment for more than it is KindlyCarsten> Subject: Re: [OSGeo-Discuss] online open source polygon mapping, like OSM?
