This data is the descendent of the "Conspub" layer that had been maintained by the UVM Spatial Analysis Lab, but it is NOT simply an update, rather it is a new layer. Over the past year VCGI and contributing partners (The Vermont Land Trust, The Nature Conservancy, The Vermont Housing and Conservation Board, The Vermont Agency of Natural Resources, and Regional Planning Commissions throughout the state) have worked to create a new data schema, associated standard, and to populate this initial release.
Please be aware that there are many known errors (gaps, omissions and overlaps) in this initial release. Many of the gaps are technically not errors as they represent private inholdings, e.g. “donut holes” in larger parcels, while many overlaps are small errors that occur when features from different sources get combined. These errors were not only expected but anticipated as a way of improving overall data accuracy by unifying various sources into a more accurate whole. The current topology report shows a total of:
- Must Not Have Gaps (donut holes), 4262 errors; and
- Must Not Overlap, 1851 errors.
Thru an iterative approach, the goal is to create an authoritative dataset of these features in the VT Open GeoData portal (VCGI’s data delivery platform) while accommodating the business needs of the many contributing organizations and those of the end users. The adoption of the Vermont Protected Lands Geospatial Data Standard and this initial data release represent the first step in that process. Combining additional and more up-to-date data submissions from our partners with a regular update interval (possibly annually) the goal of a stable dataset with minimal duplicate features or topological errors will eventually be realized.
If your organization would like to utilize this standard please contact VCGI for metadata and geodatabase templates that can help in the conversion to, or creation of, data that meets this Data Standard; or email firstname.lastname@example.org.
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).
Join your geospatial colleagues for casual conversation that may range from arcpy to apple pie and hopefully won't veer into politics (no promises, though). Three Penny Taproom has great food and drinks, so you can choose to partake or just stop in for a quick hello. All are welcome and we guarantee that someone (Leslie) will be there from 5 pm - 8 PM, wearing a map on my head (or something).
When: September 28, 2016, 5 PM - 8 PM
Where: Three Penny Taproom, 108 Main St., Montpelier, VT.
