VTrans Policy, Planning & Intermodal Development Division Mapping Unit

Projects and Accomplishments Light Detection & Ranging (LiDAR) Technology VTrans Mapping is utilizing LiDAR data and technology to support VTrans activities and has acquired high resolution data for 122 miles of highway corridors damaged by TS Irene and the Interstate 89, 91 and 189 corridors. LiDAR data is high resolution terrain data that allows for increased 3D modeling and analysis. Derived products include hill shades, contours, slope & aspect data, and other visualization layers. The primary uses at VTrans are as follows: Project Design and Survey Support Road Centerline Identification and Mapping Environmental and Archeological Assessment Geomorphology and Stormwater Assessment VTrans is working cooperatively with the Vermont Center for Geographic Information and the US Geologic Survey on the acquisition of LiDAR data throughout the State, in support of Agency activities. Highway Mapping System The VTrans Mapping Unit annually produces General Highway Maps, also known as Town Highway Maps for municipalities that have supplied changes on the Certificate of Highway Mileage. Over the course of the last year, Mapping has implemented a new system that allows for the Town Highway Maps to be produced far more rapidly than in the past. In years past, Mapping would only produce the 50 to 60 maps for towns, cities and villages that had changes supplied. In 2013, 243 maps were produced. The goal for 2014 is to produce the full series of Town Highway Maps, which includes roughly 320 maps. Route Log System Mapping is leveraging the same principles with the production of the Route Logs, which are the straight line diagrams of the Federal Aid Highway System. A draft series of the Route Logs have been produced and made available to Agency staff and are under review. Over the course of the next year, a new set of Route Logs will be produced and posted for on-line viewing and download. The Route Logs provide an overview of the highway network and a snapshot of the information pertaining to a specific section of road, including widths, curve & grade, projects, AADT, crashes and other geometric information.

Vermont LiDAR Initiative: Critical Infrastructure

Introduction Highly accurate elevation data on hydrologic features, landforms, infrastructure and other features is beneficial for improving flood readiness, public safety and emergency management, water quality, conservation management and decision support. Light Detection and Ranging (LiDAR) technology is currently the most efficient and cost effective means of acquiring this data for the state. Current coverage is 45% with an estimated $1.9 million needed to complete the state.

Post TS Irene, the public safety, emergency and environmental resource communities joined a broad range of other critical state interests in identifying statewide high resolution elevation data as a critical need. With assistance from the state and matching funds from federal partners this initiative can achieve full state coverage by 2015.

LiDAR = Critical Infrastructure Just as roads, bridges and water supply were the physical infra-structure of the industrial age, electronic data is the infra-structure of the digital age.

Few sources of geospatial data offer the richness of “LiDAR as infrastructure” to inform todays more technical society.

Flood Risk Management

Currently half the state is without

Digital Flood Insurance Rate

Maps (DFIRMs), and other areas

need updated studies. DFIRMs

help inform flood hazard areas

permitting by municipalities and

state agencies and also flood

damage mitigation planning.

Infrastructure Management

LiDAR is used in preliminary

project and construction planning

of culverts, bridges and roads and

provides more accurate storm

water modeling results. It also

improves road centerline data and

linear referencing system accuracy

and the identification of “Ancient

Roads”, class 4 town highways,

legal trails and historic features.

Ancient Road on "Bare Earth" DEM

Natural Resources Conservation LiDAR helps identify water flow paths across farmland to aid water quality protection, the restoration activities of poor cropland back into wetlands, planning riparian area practices and reduces onsite engineering activities.

Site specific maps afford technical

staff the ability to conduct

advance planning and assessment

at the individual site level, thus

improving conservation planning

efficiency, identification of site

Ancient Road on Aerial Imagery Only

specific water quality concerns and

focusing outreach.

Water Supply and Quality

Enhanced elevation data also

supports fluvial geomorphic

assessments, river corridor

delineation and informs critical

analyses identifying non-point

phosphorus inputs to Lake

Champlain and other basins.

Renewable Energy

LiDAR derived 3-D Digital Surface

Model (DSM) accounts for tree

canopy, shading, building shape,

rooftops and other infrastructure

affording the ability to model

solar potential for both roof and

ground mount solar photovoltaic

(PV) and thermal arrays.

Solar Potential Mapping

Other renewables such as wind,

biomass, hydro and their support

infrastructure also benefit from

the use of highly accurate Digital

Elevation Models (DEM’s) and

“derivatives” such as slope, aspect

and contour data.

Goals and Benefits Completed in 2011, the National Enhanced Elevation Assessment (NEEA) sponsored by the National

Digital Elevation Program’s (NDEP) 12 Federal member Agency documents the need and value of high quality topographic information, acquired via terrestrial or airborne LiDAR. Subsequently, NDEP created the “3D Elevation Program” initiative adopting the top ten “enhanced elevation data support critical applications” identified in the NEEA that apply to Vermont:

Table 1. Top NEEA business uses

# Business use

1 Flood risk management

2 Infrastructure/constr. mngmnt

3 Natural resources conservation

4 Agriculture and precision farming

5 Water supply and quality

6 Wildfire manage/plan/response

7 Geologic resources and hazard

8 Forest resources management

9 River/stream resource mngmnt

10 Aviation navigation and safety

This initiative was also endorsed by the National States Geographic Information Council and the National Geospatial Advisory Committee. The confluence of support for data acquisition is reflected in the 3DEP primary goal to “systematically collect enhanced elevation data … over the conterminous United States…on an 8-year schedule.”

LiDAR at a Glance LiDAR is a remote sensing method using light in the form of a pulsed laser to measure ranges (variable distances) to the Earth yielding precise elevation data. When combined with other data it generates precise, 3D information about the shape of the Earth, i.e., “Bare Earth” DEMs, DSMs and their “derivatives”. The combined utility of LiDAR elevation products supports such a wide array of applications that it can truly be considered a form of

critical digital infrastructure. For more technical details see the “More Info” section below.

Coordination/Implementation In 2012 the Vermont Center for Geographic Information (VCGI) formed the “LiDAR Workgroup” as a strategic response to Hurricane Irene with the goals of supporting the coordination, acquisition and dissemination of statewide LiDAR. The group is currently comprised of federal, state and local partners: U.S. Geological Survey, National Resource Conservation Service, UVM Spatial Analysis Lab, VT Assoc. of Planning & Dev. Agencies, VCGI, VT Agency of Natural Resources, Lake Champlain Basin Program, U.S. Forest Service, VT Electric Coop, VT Sustainable Jobs Fund and the VT Geological Survey.

Summary As the state GIS coordinating organization, VCGI is committed to the success and long-term support of this effort. Existing and future data from this program will be shared with appropriate federal data portals to provide the public with multiple data access points.
