MassGIS building file converted to OSM format

Posted by jremillard on 9 December 2012 in English (English)

Last week the Massachusetts mapping department (MassGIS) released data for all of the buildings in the state.

Since it is likely that next year we will be importing this data into OSM to support addresses, I figured it would be useful to convert the files to OSM format and share them.

The data is here.

MassGIS Buildings Converted to OSM format

Each town in MA has its own ZIP file. In each zip file is two OSM files. One OSM file has all of the buildings in the MassGIS data set. The second file has just the buildings that are missing from OSM.

If you are mapping in MA, please take a look.

Have these been cleared to start importing?

Or are we still waiting for a decision to be hashed out?

Okay sorry about the double posting. Looks like there is a glitch in the commenting system. When I post it I can see the post but when I refresh the last post gets cut off.. So When I post this one I will be able to see the first three posts but this will be cut off.. To Trac I go!

Hi,

We are talking about it on the us-talk.

http://lists.openstreetmap.org/pipermail/talk-us/2012-December/009762.html

Basically, the license is fine because it comes from MassGIS. Nobody has signed up to actually push this into OSM yet. I was hoping that people that are mapping in MA, would take a look at the data and see what it looks like first then we can see what makes sense to do next.

Thanks Jason.

Okay well I have some progress on this.. I spent a bunch of time coming up with a spreadsheet for the data. It can be found here: https://docs.google.com/spreadsheet/ccc?key=0Ar0iC0thXzOjdFc4c3diOGZiNlNtX2ZoOVNacTE3R3c

I have listed every city that you have a data file with. Using a public spreadsheet instead of the wiki tends to make things less complicated I have found with previous large scale imports.

I'm going to take a look at the data for a couple of the cities I have work on in the past in MA. If it looks good I'll probably the city a go. I took a quick look this morning and the data appears to be very high quality and well which is what I would expect from massGIS. Could you post the link to the list? I currently lack email access as it is blocked by my work.
