NYC Geocoding

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.

GIS Workshop – Geocoding

geocodeWe will continue with the GIS summer workshop series with a workshop tomorrow, Wednesday 6/15 on  geocoding. There’s still plenty of room if you’d like to register.

Geocoding can be described as the process of translating addresses or other unique locations into spatial data, assigning coordinates and plotting them on a map. The process can seem deceptively easy given how easy it is to plot an address using any of the numerous services such as Google Maps, Yahoo, etc.

 That said, understanding what goes on under the hood and using that information can make a big difference on the accuracy of the results when performing geocoding in your own projects, especially if you are working with hundreds or even millions of addresses.

Understanding how to properly format your data, choosing the best base layer or road network based on the precision needed or date of the data, as well as taking advantage of tools in ArcGIS to help clean your data can make a big difference.

This hands-on workshop on geocoding will help understand how the geocoding process works and offer suggestions on making the right decisions throughout the whole process.

Summer GIS Workshops

 

gis_logo_smallWe’ve put together a GIS workhsop series starting this week Wednesday 5/25 and running just about every Wednesday  through early August.

The workshops focus on both core GIS skills such as understanding coordinate systems & projections, georeferencing and geocoding and a couple workshops focusing on Model Builder, ArcPy, Google Earth Pro and working with KML.

The Intro to GIS workshop is this Wednesday, 5/25 at 11am in Lehman Library, room 215. Registration is now open.

With the exception of the Model Builder and ArcPy workshops, attendance to a previous workshop isn’t necessary, just keep in mind that most workshops require some basic knowledge of GIS to attend.

Geocoding Using ArcGIS Workshop

Date: Friday February 27th
Time: 11am – 1pm
Location: 215 Lehman Library (EDS)

I know it’s been a while since we’ve posted something but I wanted to announce that we’ve finally got around to rescheduling the canceled geocoding workshop that was supposed to happen last semester.

If you are around this Friday and are interested, we’re planning on covering the following topics.

  • Geocoding techniques
  • Preparing data for geocoding
  • Improving geocoding results
  • Dealing with common errors

We’ll have two or three hands-on exercises to do, and although no prior experience using ArcGIS is necessary to attend the workshop, it is recommended to have at least some exposure to ArcGIS.

Registration is on the EDS workshops page
