With a successful collaboration between DSSC and ESRI, a hands-on workshop on ESRI R plugin was presented by Shaun Walbridge, a senior developer from ESRI, on Wednesday, April 20. Shaun provided an in-depth tutorial on how to use R in ESRI, and answered questions from students and librarians.
Our audiences were from a broad background: librarians from Columbia and other institutions in NYC, PhD students, Master’s students, people from administrations, etc.

NYC Dept of City Planning offers a few options for geocoding including a stand alone application called Geosupport, which personally, I don’t find the easiest to use, and a Geoclient API. But for geocoding in ArcGIS quickly, or if you have hundreds of thousands, or even millions of addresses I find LION to be the best option. The only problem, as of release 12C, the geodatabase no longer includes the locators for borough & zip. The current version is 15A,
We’ve taken the old locators from 12C and imported them into the latest version which seems to work pretty well. This is available on the spatial data on the internet page, and we generally update this with each new release.
We’re offering an Intro to GIS workshop this Friday starting at 10:30am, there’s still plenty of room left if you are interested in attending. [more info…]
