[HOT] SDS Preparation/Project-Setup

[Joseph Reeves]

Hi Alex,


Kate says I need to associate with a "feature" and I am still working on
understanding what a feature is.  Is that a multipoint geojson object?  Is
a doorway a feature if it is a way?  Should I be associating with buildings
instead?  I am thinking that nodes are not features, then?

I'm just jumping in without knowing what your project is. but I would guess
that the feature Kate is suggesting is any OSM feature: a way or a node.

A doorway represented in OSM as a way would work, but a node would
presumably be easier (just from a recording point of view).

My memory of SDS is hazy, but I'm pretty sure that a OSM node works as an
associable feature; in a doorway example, therefore, you'd put the building
into OSM, tag the doorway and associate your SDS entry with the doorway
feature ID.

For example. Lincoln College is your building:

http://www.openstreetmap.org/way/113000693

Your door:

http://www.openstreetmap.org/node/2373213127

So your SDS data is tied to the feature: node 2373213127.

Does that help at all?

Cheers, Joseph
