NYC TreesCount! Data was collected by 2,300 volunteers going street-tree to street-tree. Watch a quick tutorial on how the 2015 TreesCount! data was collected.

For the day, we will explore these five challenges. We have seeded your data discovery process with this google-doc-as-a-wiki. Please be kind, share your knowledge.

NYC Parks has pruned several open data sets for you. Dig into the MillionTreesNYC block planting locations, the 1995 data, 2005 data (geospatial and tabular), or 2015 data.

The 2015 data is broken up into two data sets, tree census data (geospatial and tabular) and census block-face data (geospatial and tabular). As NYC Parks ensures all of the collected data is accurate, you can overlay the tree census data on top of the block-face data. Here is a copy the TreesCount! 2015 tree census data dictionary.

On the community site, we will post more datasets under discussions.

Tools and stuff to bring!!

Do not forget your laptop and power supply! If you are bringing a little one, feel free to bring their stroller and anything else they need.

If you are into slack, BetaNYC has your back! Additionally, you can set up your own team channel! ;-)
