VT Open Geodata Portal Replaces VT GIS Data Warehouse!

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).

 


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).

Intro to GIS and GPS Training Offered

February 18, 2016

2016 GIS Training at VERMONT TECH: Registration Open!
VTC hosts an Introduction to GIS and GPS class taught by VCGI staff. NEW THIS YEAR: Two different time/formats and times of year! We will be offering this course in the spring as an 8-week series of 2-hour evening classes in Williston. In the fall, we will offer it as a two-day course completed over two Saturdays. Choose the time frame and location that works for you!

Intro to GIS/GPS ($100) :
Participants will gain an understanding of fundamental geospatial concepts which they will then apply in learning how to use online mapping applications, consumer grade GPS receivers, and QGIS open source GIS software. QGIS will be used to explore and display geospatial data, to create new geospatial data, to perform simple geospatial analysis, and to compose basic maps appropriate for printing or publishing. Participants will develop a mapping question or project that they will explore and build on throughout the course.

April 14 – June 2 (Williston Campus) – Eight Thursday evenings, 6:30 – 8:30 PM. Click here to register: http://greentrainings.vtc.edu/gis-trainings.html
September 10 and 17(Randolph Campus) – Two Saturdays, 9-5 each. Click here to register: http://greentrainings.vtc.edu/gis-trainings.html
