[OHM] Building Infrastructure for OHM ­­ RPA Historic Wetland Mapping

[Tim Waters]

Ahh yes, sorry, currently there are no plans for batch imports of maps for
public users.

Organisations with hundreds or thousands of images tend to run their own
warper instance and connect it up to their repository and metadata
services, as everyone keeps their images and the data about the images in
different formats etc. An example from the US Govt -
http://warp.nepanode.anl.gov/ by the DoE / NEPA

One solution we are building for public organisations and their old maps is
to add them to Wikimedia Commons and then import an entire Wiki Category
into the Wikimaps Warper. That warper also has an embedded
OpenHistoricalMap iD editor. This import process will be live before the
end of the month. This is also the project which will have the ability to
import batch control points.

Regards,

Tim

Thanks for the reply, Tim – and for building out a tool like mapwarper.net.

I was thinking more about batch import of maps, rather than control points.

I've had a chance to play around with it a bit and was getting some of the
distortion you mentioned, which is likely unavoidable. I'm going to test
the same map in ArcGIS and in MapWarper – I have a feeling I will get a
similar amount of distortion in each. Some of it may come down to adding
points to adjust the map by eye.
