[Talk-ca] Building Import

[Begin Daniel]

Hi Jarek, 
There is actually no standard “code” available since I use FME (www.safe.com). It is a proprietary ETL application and all operations are done using “transformers” (https://www.safe.com/transformers/). I can provide you with the workbench I developed (a bunch of linked transformers) but you need a license to run it. This is why I tried to describe the operations I run on the data in the wiki. 

As you did, people may send me coordinates (bounding box) of an area they know well. I’ll process the area and send the results back in OSM format. Please, be reasonable on the amount of data to process ;-)

Cheers,
Daniel

Hi Daniel,

Thank you for your work on this.

Are you able to share the application or code in any way? I did not
see any links in the talk page. It is really not possible to say much
without looking at what the code does with some of the buildings with
geometries I'm familiar with.

Alternatively shall we send you over an area we're familiar with and
you could send over the results of the tool? But I am concerned that
would scale really poorly.

To give a concrete example, I would be curious about the output of the
tool for area 43.6450,-79.4071,43.6358,-79.4289 - I know that the
geometries already in OSM for the area are partially inaccurate or
overly simplified, so I'm curious how the processed import data looks.

Thanks again,
