I'm trying to find a multipoint shapefile to do some testing for an application I'm working on, but I cannot seem to find one (and do not have ArcGIS to create one). Can anyone suggest a place to find a sample multipoint shapefile?

I uploaded a part of the dataset I'm working with regularly. Due to user error restrictions, it has to be a multipoint layer instead of just a point one, but most features will have only one point as the multipoint. Anyway, you can grab it here. It will stay there for posterity's sake.
In general, you could create it with other software, some free like QGIS, or write it as WKT and use a converter. GDAL/OGR come to mind, but there are also free online versions like GeoConverter.

Thanks for posting that. I have QGIS, though not sure how to create a multi point from that. But I probably could have created a simple one with GDAL - thanks! Commented Jul 23, 2012 at 15:55

Actually I don't think QGIS will do it, I just tried creating a point shapefile in QGIS, adding a few points, and merging them. When I tried to save my edits it said I couldn't save a Multipoint feature in a Point layer. But there is no option to specify multipoint geometry when you're creating a shapefile in QGIS.– Dan CCommented Jul 23, 2012 at 16:12

Import multipoint WKT as a new layer (Delimited text layer in the menu). You can get dummy data by copy-pasting a few selected values from a point layer to a text editor, running a search&replace and saving it as a CSV. Commented Jul 23, 2012 at 16:19

1Since I downloaded the file and nearly despaired trying to read it: It does not contain MultiPoint (shape type: 8) shapes but MultiPointZ (shape type: 18) shapes. And in addition to that the optional M-values are missing so the ContentLength is 40 words (80 bytes) rather than the expected 64 words (128 bytes). With that in mind it reads fine.

The English Heritage Listed Buildings Dataset is Multipoint.
