NB_170_17_1 - NB 170-17-1 CGI – High-Resolution Elevation Data
NB 170-17-1 CGI – High-Resolution Elevation Data
National Bulletin: 170-17-1 Date: February 13, 2017
Subject:  CGI – High-Resolution Elevation Data


Action Required By:   March 20, 2017 
 
Purpose.  To acquire high-resolution elevation data (LiDAR or IFSAR geospatial products) to support conservation planning, engineering planning and design, development, and maintenance of digital soil surveys, terrain mapping, resource inventory, and assessments.  The NRCS national elevation leader requests the next 3 fiscal years of elevation projects to be submitted to the National Geospatial Center of Excellence (NGCE) for national strategic planning in support of the 3D Elevation Program (3DEP). 
 
Expiration Date. September 30, 2017  
 
Background.  

Quality topographic and other base-map materials are needed for engineering, conservation planning and design, terrain mapping, and soil mapping or updating existing maps. The NRCS has made geospatial investments for the acquisition of geospatial products.  The purpose is to accommodate new technology used in conservation planning, engineering planning and design, development and maintenance of digital soil surveys, terrain mapping, resource inventory, and assessments.

Purchase of the following types of materials will be considered:

High-resolution elevation data from airborne or satellite platforms

Light Detection and Ranging (LiDAR) with a vertical accuracy of 10 cm RMSE2 (QL2) or better

Interferometic Synthetic Aperture Radar (IFSAR) with 5-meter posting

Orthophotography - Leaf-off imagery or four-band imagery will be considered where needed

Hyper spectral imagery or remote sensing projects needed to enhance geospatial science efforts       
 
Explanation.  Requests from States can be facilitated by the State GIS specialists.  This year, we published a layer in ArcGIS Online allowing live editing for submissions with metadata; however, we will accept shapefiles and file geodatabases of the project area in the schema provided.  The project description should include all of the following information:  geographic area of coverage, type of geospatial products needed, resolution, quality level, and specifications, as described in the USGS LiDAR Base Specification version 1.2 https://pubs.usgs.gov/tm/11b4/pdf/tm11-B4.pdf and the estimated cost of the project.  If the State NRCS office is proposing to use their funds towards the project, include the type of funds available, with fund codes, from your State allocation to contribute toward the purchase of requested geospatial products.  NGCE will work with 3DEP stakeholders to prioritize all requests and cost share with Federal, State, and local partners based on available funds.  Priority will be given to projects where one or more of the following criteria are met: 

NRCS priority / initiative areas

High priority or target area for conservation or environmental analysis

States and partners may share part of the cost

The goal is to combine NRCS State office projects and funds with national initiative funds from the Soil Science and Resource Assessment deputy area.  NGCE recommends that all NRCS elevation projects be submitted via the Broad Agency Announcement for 3D Elevation Program (3DEP) planned for release this summer.  NRCS NGCE is a member of the 3DEP executive committee and has input to the BAA process to select and help fund elevation projects that align with agency priorities and requirements. Proposals will be selected in the fall of 2017 for joint funding. 3DEP partners are attempting to determine requirements for the next 3 fiscal years.

If you have no base-map material needs for fiscal years 2017, 2018, and 2019, please provide a negative response to this bulletin.

Submission Format.—A template file geodatabase and instructions will be provided on NRCS ArcGIS Online: http://arcg.is/2lzKD1m Please submit requirements in this template filling in the “CollectionYear” field to indicate when this data will be a priority.  To view project proposals from all agencies last year, visit http://fedmap.seasketch.org
