VCGI has posted a Parcel Boundaries Web Map Service that will be updated at least annually as we receive updated parcel data. Web map services allow users to bring map layers and imagery into their GIS projects or map mashups without actually downloading any data by connecting to the service of choice via the internet.
Contact Leslie (email@example.com or 802-882-3002) if you need help understanding how to connect to this service. More info here: http://vcgi.vermont.gov/warehouse/web_services/map

With technical support from our partners in the Enterprise Geospatial Consortium LiDAR Workgroup (a.k.a. VTeam LiDAR), VCGI is happy to announce the initial offering of LiDAR “derivative data” under the umbrella of the “Vermont LiDAR Initiative” effort. For more information on the effort, the state LiDAR plan, status graphics and other support data please visit the new VCGI LiDAR web page at http://vcgi.vermont.gov/lidar.
Current data availability includes 1.4m resolution Digital Surface Models (DSMs) “ElevationOther_DSM1p4m” and Digital Elevation Models (DEMs) “ElevationDEM_DEM1p4m“ covering the Missisquoi subbasin and a majority of Bennington County. 2’ Contours from these areas will be integrated with the existing 2’ contour layer “ElevationOther_CN2T” early in the New Year. See the LiDAR web page for status graphic, project data extents and more.
To download these data select the “download” icon located in the “All new or updated data” of the “Data and Imagery” page http://vcgi.vermont.gov/warehouse/search_tools. All LiDAR raster data is in the Erdas Imagine file format and organized at two levels for flexibility in downloading:
1) Ortho 9 tiling scheme; and
2) Original project “footprint” extent – as delivered by vendors.
Index maps and Index shapefiles are provided in the download data folders to help users find tiles of interest, e.g., “_Index_ElevationDEM_DEM1p4m.pdf” and “_Index_ElevationDEM_DEM.zip”.
For a readily available advocacy/information brochure please see the “VT LiDAR Initiative Brochure” on the vcgi.vermont.gov/lidar web page.
- Addison County Data - Release of the data is still pending QAQC issues with the vendor. No firm delivery date is available.
- Essex County Data – Missing data tile discovered upon regenerate DEM & DSM from source point cloud has slowed release of this extent. Efforts underway to recover it and move forward. Original vendor delivery only included a 3m resolution DEM/DSM though data supports 1m resolution, thus the recreation effort. IF YOU THINK YOU HAVE THE ORIGINAL “POINT CLOUD” SOURCE DATA FOR 2005 ESSEX COUNTY PLEASE CONTACT ME!
- ALL-LDR Product – External hard drive containing all available LiDAR data including “point cloud” and all derivatives. For information and links to vendor supplied “point cloud” metadata see -http://vcgi.vermont.gov/warehouse/products/ALL-LDR_MIX_LIDAR_STATE_ALL
- Secondary derivative layers: “ElevationOther_ASPECT1p4m”, “ElevationOther_HILSH” (hillshade), “ElevationOther_nDSM” (“normalized” DSM) and “ElevationSlope_SLOPE” raster layers will be made available via the VGIS as time permits in 2014. These are available on the ALL-LDR product for project extents they have been generated for (ATM: Missisquoi subbasin and Bennington County).
Please feel free to contact me directly with questions and/or feedback about the data, the VT LiDAR Initiative or the LiDAR web page etc: firstname.lastname@example.org or 802-882-3008

From Sensors and Systems:
“Is my property being taxed fairly?”
“Are zoning variances being granted in a consistent manner?”
“Is my flood insurance rate justified?”
These are the types of questions concerned citizens may ask, both in their own interest, and in the interest of maintaining a responsive and equitable democracy. Our democratic system of government is supposed to conduct the public’s business fairly and consistently within the explicit directives of the citizens’ elected representatives. But how can citizens know if that is happening? And how can citizens know that their representatives are actually conducting “the people’s business” rather than their own? Transparency is required for maintaining our governments’ accountability to its citizens.
Transparency means giving citizens access to their governments’ records, to the same information that government agencies themselves use to make decisions and conduct operations. With it, interested persons can understand, verify, and possibly challenge a governmental action. Since most governmental actions impact specific locations, geographic information is critical to governmental accountability, and GIS technology and professionals are critical to analyzing that information.

VCGI’s webinar line up for December:
Getting Started With Python
Learning to Map in an ”App” World: discover the power of mapping with your phone
Quantum GIS: Data Acquisition and Transformation (a repeat due to technical difficulties and lack of success recording)

Todd Sears, Bethel, VT (excerpted from the VT Council on Rural Development Web Site, see link below)
“…C+ is actively exploring ways by which information technology (IT) and web functionality can enable and enhance the role of the citizen during an emergency. This could involve how to best harness social networking sites such as Twitter, Facebook, Front Porch Forum and others like them to expand and add an extra layer of communication and trust to the information created and used about the disaster by the affected municipality. Where yesterday we were concerned with the conventional media outlets and actions, today we must embrace and take advantage of other more progressive options as well.
One of the more exciting applications C+ is experimenting with is called Ushahidi, a freeware, crowd-sourced geospatial information application which allows near real-time plotting of various forms of media onto a map from the field. Imagine a scenario where a stranded neighborhood member, after the worst of a disaster has passed, walks his or her area to take stock of the situation, comes across a neighbor with an injury, a fallen power line, a washed out road, or a collapsed bridge. With a smartphone loaded with a free app and a few button clicks, that person can take a picture (or a video, or write a text narrative) of the situation, and immediately have it plot out onto a web-based map in the municipal Emergency Operations Center or Incident Command Post. An icon appears on the map where the incident has occurred; the operator at the workstation clicks on it, and sees a photo of the phenomenon, with amplifying descriptive information. The implications for immediate response and future planning are staggering.”
