Today sees the release of CityEngine 2011, recently acquired by ESRI and being integrated into the core of their software offerings. This package fits in nicely with Jack Dangermond’s ideas on GeoDesign (you can also read more here). The ESRI user conference in Madrid today will be when it is officially released, but what will the new release contain and what improvements will ESRI bring to the table (aside from some cosmetic changes).
New features I have spotted so far include:
- georefenced terrain and texture maps can now be used with support for GeoTIFFS (at last!)
- file formats for import supported (including ESRI’s geodatabase and KML)
- export file formats supported (including KML)
- support for coordinate system when importing Shapefile (I hope this works the way I think it should work!)
- new subdivision method – skeleton subdivision (will have to see how this works in practice)
- Smooth streets
- geometry.isOrientated function
- getGeoCoord function
- styles – not exactly sure what this is yet but it looks potentially very useful and a style manager
I’m glad there’s is increased support for GIS file formats (namely KML and GDB) but I haven’t managed to find out whether object attributes set in CityEngine are now automatically written back to a shapefile upon export without the need to dive into Python scripting (which is only available at PRO level). I really hope it does this for the versions that can export to shapefiles as it is in my view a hugely important feature essentially for working with ArcGIS.
In summary this looks to be what I was hoping for from CityEngine, a refinement of the interface and increase in support for proper GIS georeferenced data, plus enhancements to the way streets and lots are created. Until I get the new update I can’t possibly comment on the software’s real life performance, but the future looks very promising.
One thing I hope ESRI doesn’t do is fragment the product too much (i.e giving a small, medium and large approach with huge feature differences between products). We use ArcMap (lets call it ArcGIS for cheapskates) in the office and increasingly QGIS seems like a much better alternative in some circumstances, as the feature set is much richer and it’s file format support better than ArcMap. Yes I know we should pay more money if we want the features, but honestly that’s not always possible.
I’ve been playing around with the export settings for placing models in SketchUp, but there has been a problem. Basically, circular elements of my models are having their vertices merged so they look like they’ve been crushed:
Turns out you just need to check the tickbox “Create Shape Groups” I don’t know why so if anyone knows just post a comment after this post…
