Hey Russell, To start off, great import wiki! +1 on my vote
Just wanted to comment on the spatial joins you are performing, we experienced the same pitfall when conducting Ottawa's OSM building import. > To achieve a match, two spatial joins were performed with the OIT address points and roofprint polygons. First using “point falling inside polygon”, then using “closest point” for the remaining records. 1. *Address fall inside polygon* (Should be a match) 2. *"Closest point"* - Normally the closest polygon doesn't mean that's the main building, it could actually be a shed or a garage depending on how accurate the address point is. *How we solved that issue:* 1. Using parcel data (seems like you have access to that type of dataset) find all the buildings which are contained inside that parcel. 2. Exclude sheds & garages (sqft 240 or less) 3. Find the largest area building (typically the main building). 4. If more than 3 buildings in the same parcel, ignore matching since this would be typically a farm land and it would be impossible to automatically match the address point with multiple building footprints. Best of luck with the import! *~~~~~~* *@DenisCarriere* *GIS Software & Systems Specialist* On Mon, Oct 2, 2017 at 8:17 PM, Russell Deffner <[email protected]> wrote: > Greetings everyone, > > > > After a long discussion and planning period locally, we are pleased to > announce the plan for importing Buildings in the Denver metro of Colorado, > United States. > > > > The import wiki is here: http://wiki.openstreetmap.org/ > wiki/Denver_Planimetrics_Import > > > > A few notes: > > * As you can see in the schedule on the wiki-page, this has been under > discussion with the local community since the beginning of the year.
