VCGI is pleased to announce the rollout of more lidar image services covering all or parts of Addison, Bennington, Chittenden, Franklin, Grand Isle, Lamoille, Orleans, Rutland, Washington, Rutland and parts of Caledonia and Orange Counties. The remaining area should have services by the end of 2017. The links below will take you directly to the Rest Endpoint Page for each service. If you are not sure what to do with a Rest Endpoint Page, check out our help video on the topic:
- VCGI is aware that both slope services descriptions erroneously refer to the service units as “degree slope”, when in fact they are “percent slope”. Technical issues are blocking our efforts to correct the description. Thank you for your patience in the meantime.
- Both the ASPECT and SLOPE image services were intentionally published with the default gray scale color ramp to support flexibility for the user. For details on how you can generate derivatives on the fly using this service, please watch the March 2017 webinar on how to use the new lidar imagery services, The Powerpoint used is posted here
- The ASPECTSYM and SLOPESYM image services were published with pre-determined color ramps (that cannot be changed) to provide users with a “cartographic ready” option.
- ASPECT and SLOPE data used in these services are not yet completely available for download (soon!)

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).
- 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!

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

State-Wide FEMA DFIRM Data Posted
A state-wide FEMA DFIRM data set (where DFIRM is available – see map) has been posted in Vermont’s Open GeoData Portal: http://vcgi.vermont.gov/opendata. This new data posting replaces the individual county-based and town-based DFIRM data sets that were previously posted to the portal. This new data set is catalogued in the portal with the database name EmergencyFlood_DFIRM; It can be found by searching with the keyword “DFIRM”.
The DFIRM data set is available through the portal as a .zip package that contains shapefiles, tables, metadata files, and a .lyr file.
VCGI appreciates VT Agency of Natural Resources (ANR) staff for keeping VCGI abreast of the status of DFIRM data and providing symbology that is incorporated into the .lyr file.
NOTE: New flood maps in Bennington County just became effective on 12/2/2015.
NOTE: See the Flood Ready Vermont web site at http://floodready.vermont.gov/ for information on flood readiness.
All VT Imagery Service Now Includes 2015!
VCGI’s full suite of imagery services have been updated with the latest 2015 VT ortho imagery (covering southern VT).
2015 Orthos have been integrated into the following services
- All “Best of” services + caches (color, color infrared, and black & white) have been updated
- All statewide “ortho only” services (color, color infrared, and black & white) have been updated
- Individual cached 2015 ortho services have been created (SP + WM)
- The “All VT Imagery and Indexes” service (version 3) has been updated to include 2015 imagery + indexes (including tie-cut lines).
NOTE: These services also take advantage of stable “layer ids” for those hackers out there, so you can count on them staying the same when you write your code.
