January 4, 2017

portal_other

The VT Center for Geographic Information (VCGI) is pleased to announce the release of a new Vermont Open Geodata Portal (geodata.vermont.gov). VCGI, in close collaboration with Vermont’s Enterprise Geospatial Consortium (EGC), has built a website (Portal) that helps constituents find, explore, and access a wealth of geospatial resources. The Portal provides access to geodata, web services, and applications originating from many sources (publishers) including numerous State agencies (e.g. VT Agency of Natural Resources, VT Agency of Transportation, VT Agency of Human Services, VT E911).

Highlights:

  • Download formats – Vector datasets are available in multiple download formats (shapefile, excel, and csv).
  • Smart search – All entries are fully indexed with tags and keywords making it easier to find what you’re looking for.
  • Data visualization – Vector datasets can be visualized using the built-in map viewer. Users can even filter the data before they download it!
  • Big Data download tools – The Portal includes special tools for “big” datasets such as imagery and lidar. These include the Tiled Data Download Tool and Clip & Zip Tool.
  • Modern web platform – The Portal leverages modern web technology supported by Esri (Environmental System Research Institute, Inc.), providing the State with an upgrade path for the future.

VCGI would like to thank our State Agency partners for their ongoing dedication to improving access to Vermont’s geospatial resources!

Public BETA Release – VT Open Geodata Portal!

November 3, 2016

The VT Center for Geographic Information (VCGI) is pleased to release a BETA version of Vermont’s new Open Geodata Portal!

http://geodata.vermont.gov

VCGI and its partners have built a website that connects publishers and consumers and helps them find, explore, contribute, and use geospatial information and resources. The VT Open Geodata Portal (Beta) “federates” geodata, web services, and geospatial applications from many sources (publishers) including several State agencies (e.g. VT Agency of Natural Resources, VT Agency of Transportation, and VT Agency of Human Services).  VCGI would like to thank our partners for their dedication to improving access to Vermont’s geospatial assets.

What do you think?  Please take a few minutes to explore the BETA site (http://geodata.vermont.gov), kick the tires, and let us know what you think (http://geodata.vermont.gov/beta_survey).  Your input will help us improve the website.  We plan to release a final version by the end of the year.  Thanks!

P.S. Known “bugs/limitations” have been documented here (http://geodata.vermont.gov/beta1_bugs).

VCGI Director Chosen

August 8, 2016

Exciting news from Pat Moulton, Secretary of ACCD:

Lucy Leriche and I are excited to announce that John Adams has been selected as the new Director of the Vermont Center for Geographic Information! Most recently, John served as Planning and Policy Manager at the Department of Housing and Community Development within the Agency of Commerce and Community Development.

John brings to VCGI experience and enthusiasm for using data and mapping to guide decision making processes across state government. Since beginning at DCHD in 2012, John has been a leader in land use policy, legislative initiatives and managing special projects – notably using GIS to improve workflows and to ensure Vermont’s public investments are supported by data. He is the primary author of Vermont’s new Planning Manual and has been a key figure in a wide variety of interagency initiatives relating to land use, housing, transportation and energy. As someone with track record of building consensus and commitment to improving customer service in state government, he was the recipient of a 2016 Public Service Recognition Award.

John is a certified professional planner who has worked at the municipal level and has taught Land Use Policy and Economics at the University of Vermont. He holds a Masters of Urban and Regional Planning from Queen’s University and a Bachelor of Arts in Environment and Development from McGill University. In his personal capacity, John volunteers on the Montpelier Planning Commission, roasts coffee and brews beer.

A search committee involving multiple agencies and partners selected John from a pool of incredibly well qualified candidates from around the country. John will start with VCGI on Tuesday, September 9th, 2016.

Please join us in congratulating John on this exciting new position!

About

The 2016 Vermont Remote Sensing Workshop will provide hands-on training with a broad range of remote sensing technologies, including Unmanned Aircraft Systems (UAS), lidar, and thermal satellite imagery. The workshop is designed to help federal, state, regional planning commission, and local GIS users improve their ability to harness the power of remotely sensed data. Funding for this workshop is provided by AmericaView and the US Department of Transportation.

Dates and Locations

  • August 9, 2016: 9AM-11AM, UAS flight operations in Waterbury, Vermont. This is an optional session and is dependent upon the weather.
  • August 10, 2016: 9AM-5PM, University of Vermont, Aiken Center (81 Carrigan Drive), Room 101. Lunch will be provided!

Register here for only $10: https://secure.vermont.gov/ACCD/eventreg/event.php?eid=75

Participants
There are 18 seats available for the August 10th training. Priority will be given to government (federal, state, regional planning commission, and municipal) employees. Participants should be very comfortable working with geospatial data and have experience with desktop GIS software.

VT LiDAR Data Upgrade & New Data!

July 18, 2016

rgi_lidar_index_sm

New LiDAR Data Available:

1.     2013 Rutland/Grand Isle data “collection” which includes the Mad River Valley (see map here):  0.7m resolution, Quality Level 2 (QL2). – DEM has been posted, Hillshade and Contours are coming soon.

2.     A pre-release portion of the 0.7m Quality Level 2 (QL2) 2014 “Eastern VT” data “collection” which includes a portion of Georgia and stretches south along the lake into Charlotte in Chittenden County (see map here). – DEM and Hillshade have been posted, Contours are coming soon.

Visit VCGI’s Open Data page and search via keyword “lidar” to see the list of new and updated data:  http://vcgi.vermont.gov/opendata

Changes to Existing Data:

NOTE: some of the data identified below did NOT make it through the posting process. We are working through some technical issues and hope to resolve them in the next couple of weeks.

1.     Updated naming convention to all LiDAR related data. E.g., “Elevation_DEM1m1020_2005.img” is now “Elevation_DEM1M2005_1020.img”.

a.     Digital Elevation Model (DEM) data now reflects its “hydro treatment”, e.g., DEM = “pure” DEM; DEMHF = “Hydro-flattened” DEM; DEMHE = “Hydro-enforced” DEM; see USGS’s “Hydro Treatments of LiDAR Derived DEMs” powerpoint for details.

2.     All downloadable data layers are in their original, vendor-delivered tiling structure, re-projected to VT State Plane Coordinate System NAD83 meters, Zunits meters and the Erdas Imagine format. This primarily affected the following collections:

a.     2008 “Lower” Missisquoi – Reimported to original 1.6m, “hydro-flattened” DEM format;

b.     2010 “Upper” Missisquoi (a.k.a. “Rock River”) – Reimported to original 1.6m, “hydro-flattened” DEM format;

c.      2012 Bennington County – Reimported to original 2m, “pure” DEM format;

3.     Only DEMs and contours (DEM/DEMHE/DEMHF) are provided in tiled format. Other derivatives are in single mosaic file format only.

a.     When contour data was part of the original vendor delivery they are in the same tile index structure as the DEMs.

b.     When contour data was not part of the original vendor delivery and created by VCGI in 2013/2014 they are in the “Ortho9” tile index.

4.     All primary (DEMs) and secondary derivatives (ASPECT, DSM, HILSHD, nDSM & SLOPE) are available in a single, mosaic file format covering the full “collection” extent.

Changes to Metadata:

  • All LiDAR metadata files have been updated to latest EGC format (May 2016).
  • For original vendor metadata see “All VT LiDAR on an External drive” main page for all project level metadata in a central location (these are original vendor metadata for LAS data).
