Max number of shapes in one geographical object

Filipvdr — Tue, 08 Jan 2019 13:09:43 GMT

Hello, at my client they want me to load some new shapes.

We are using SAS VA 7.2. They want to make an extra "specific" region which goes up to 18.000 different area's. Is this possible? Does a maximum exist?

There are cardinality limits. Please see

Also, if you are referring to custom polygons, then that is not supported in 7.2. Support for custom polygons was added in 7.4.

As mentioned in the previous reply - we don't officially support loading custom polygons in VA 7.2. You could try the technique described for 7.4: http://support.sas.com/documentation/cdl/en/vaag/69958/HTML/default/viewer.htm#n09tvhnyrosr8mn1nmw7u3akrb1e.htm . I believe the underlying lookup tables are the same. There is no real application side limit for the max number of polygons here - but typically your underlying polygon data set will become too large to load beyond 50k or so. So typically you either reduce the number of polygons or point density (e.g. use proc greduce).

FYI - in VA 8.x - we have a limit of 250k polygons per request. More details are here https://go.documentation.sas.com/?docsetId=caldatamgmtcas&docsetTarget=p1dwawsidsczlpn121j0glleicxp.htm&docsetVersion=3.4&locale=en

Hope this helps. Falko

Thanks for the replies.

I'm aware that it's not supported for 7.2, but we already managed to load several different shapes (municipality's for Belgium - which are not standard provided and other specifif regions.)

In previous cases we had about 10 - 250 different id's. But now it goes up to 19.000. So without any drilldown, or filter, it seems I will have too many values to display.

You might try adding a required prompt to display just one region (or other subset) at a time.
