[TCMUG] Building heights Minneapolis/ St. Paul?

[Brian Fischer]

We did a project for the City of Minneapolis a few years ago for a noise study where we calculated building heights off of the LiDAR.  I don’t know if they would give you that data or not.  It was for their environmental department.   I can tell you there are some buildings that get complicated because of skywalks and multiple tiers to a building so the accuracy get’s questionable is edge cases.

Depending on what you are using it for does leave a lot of questions about what height you need.

Average/max, height? Height above ground or above datum?  What is a building (sheds?, big multi part buildings like hospitals?).

St. Paul and presumably Minneapolis have a building footprint dataset.

The more recent Lidar data also typically has the building points classified in the point clouds.

Could you join the MSFT foot print dataset with the lidar data to get an average height per building?

I don't know if there is a database with a single number per building, but the information can be extracted from the various Lidar datasets (with the caveat that they are getting somewhat dated and in one of the collects they clipped off the tops of the buildings in downtown Minneapolis.)

Hello,

Hope all of you are well!

I'm looking for building heights data for Minneapolis/ St. Paul, ideally Hennepin and Ramsey Counties.  Does this exist?

Thanks,
Jennifer
