New and Updated Data Posted!

From our Database Administrator, Ivan Brown:

A lot of data was posted to Vermont’s Open GeoData Portal ( http://vcgi.vermont.gov/opendata ) during late 2016 (and 2016 isn’t over!).  I want to highlight some recent data posts.

Parcels: The Vermont parcels dataset (CadastralParcels_VTPARCELS) has been updated with 6 new towns providing parcel data for the first time and 33 towns providing updated data (update 2016A).  Thank you to the Regional Planning Commissions for supporting the effort to collect parcel data and make it accessible! Additional parcel datasets are already in the queue for an update to be conducted in 2017. Visit this 2016A Update page for details!

The new Vermont Statewide Property Parcel Mapping Project and the new Vermont Statewide Property Parcel Mapping Program are gearing up.  The project and program will yield a lot of benefits to the state, including consistent parcel data structures, efficient parcel data exchange/aggregation/use, and increased parcel data coverage.  For more information on the Vermont Statewide Property Parcel Mapping Project and the Vermont Statewide Property Parcel Mapping Program, go to http://vcgi.vermont.gov/parcels .

Lidar: An enormous number of lidar data derivatives were posted to Vermont’s Open GeoData Portal during 2016.  Also, more lidar data resources are always moving along the conveyor belt as lidar data coverage increases.  The lidar data derivatives can be discovered by searching Vermont’s Open GeoData Portal ( http://vcgi.vermont.gov/opendata  ) with the keyword “lidar” or by simply clicking on the “LIDAR related data” link.

County/Town Boundaries:  VCGI recently completed a long-awaited update to the State’s county, town, and village GIS dataset (BNDHASH).  This dataset combines (“hashes together”) data from “best available sources” to map the location of county, town, and village boundary lines.  VCGI leverages information from official surveys (when available), parcel datasets (recent), and other agency datasets (e.g. VTrans’ county/town boundary data).  This information is reviewed and weighed against existing boundary lines and supporting documentation to determine if the information should be used.  The goal is to improve the data over time.  The latest BNDHASH boundary data is available from VCGI’s Open Geodata Portal (http://vcgi.vermont.gov/opendata).  PLEASE NOTE:  BNDHASH feature class names have changed;  This may impact .mxd files, etc. when the new files are swapped.  The associated Vermont Geographic Area Code lookup tables “GEOCODES”, which are based on the VGIS standard, have also been updated.
