Ulster County 2ft Contours

This data set contains topographic contour lines of Ulster County, NY, for cartographic display and relief analysis. Produced from the 2014 LiDAR dataset and 2015 topographic 1m Digital Elevation Model. Contour intervals of 2 feet were produced in NAD_1983_2011_UTM_Zone_18N Projected Coordinate System. Due to the size of the dataset, it has been broken into small shapefile tiles available for download at http://ulstercountyny.gov/maps/contours/. These files can be used in any GIS application and imported into AutoCAD. If you wish to obtain a complete set of this contour data it is available in an ESRI v9.3.1 geodatabase, compressed to (~6GB). Users will be required to provide a hard drive for transfer.

Digital Elevation Models (DEMs)

U.S. Geological Survey

The purpose of this LiDAR data was to produce high accuracy 3D elevation products, including tiled LiDAR in LAS 1.2 format, 3D breaklines, and 1 meter cell size hydro flattened Digital Elevation Models (DEMs). All products follow and comply with USGS Program Lidar Base Specification Version 1.0. The DEMs were made from multiple LIDAR collection projects. The DEM files can be downloaded from the NYS Orthoimagery Application below..

3rd Party - Water Resources

National Hydrography Dataset (NHD)

United States Geological Survey (USGS)

The National Hydrography Dataset (NHD) is the surface water component of The National Map. It contains features such as lakes, ponds, streams, rivers, canals, dams and streamgages. NHD contains a flow network that allows for tracing water downstream or upstream. It also uses an addressing system based on reach codes and linear referencing to link specific information about the water such as water discharge rates, water quality, and fish population. Using basic NHD features like flow network, linked information, and other characteristics, it is possible to study cause and effect relationships, such as how a source of poor water quality upstream might affect a fish population downstream.

National Flood Hazard Layer

Federal Emergency Management Agency (FEMA)

National Flood Hazard Layer (NFHL) dataset is a compilation of effective Flood Insurance Rate Map (FIRM) databases (a collection of the digital data that are used in GIS systems for creating new Flood Insurance Rate Maps) and Letters of Map Change (Letters of Map Amendment and Letters of Map Revision only) that create a seamless GIS data layer for United States and its territories. The NFHL is updated as new study or LOMC data becomes effective. Note: Currently, not all areas have modernized FIRM database data available. As a result, users may need to refer to the effective Flood Insurance Rate Map for effective flood hazard information. County and community-based NFHL extracts are updated as new data is received, however State extracts are updated only once every two weeks if new data is received during the two week window.

3rd Party - Environmental Data

Biologically Important Areas

NYS DEC Natural Heritage Program

This dataset indicates areas of biological and ecological importance to the health of the Hudson River estuary. Only areas not currently under public or private conservation management were included. Areas were included if they contain vulnerable, exemplary, and highly diverse clusters of species and habitats. Special consideration was given if the habitat and species are of global, state, and/or regional importance.

Submerged Aquatic Vegetation

NYS Department of Environmental Conservation

Submerged aquatic vegetation (SAV) is an important habitat and site of primary production in many aquatic ecosystems but there was no baseline information on SAV extent or distribution in the tidal freshwater Hudson River. In 1994, a collaboration was initiated between the Institute of Ecosystem Studies (IES), the Hudson River National Estuarine Research Reserve/NYSDEC and the Cornell Laboratory for Environmental Applications of Remote Sensing (CLEARS, now the Cornell Institute for Resource Information Systems (IRIS) http://www.css.cornell.edu/iris/index.htm. These groups provided diverse expertise to enable the first broad delimitation of SAV in the Hudson.
