BAA Grant Process

USGS Liaison – Claire Devaughan

cdevaugh@usgs.gov #512-927-3583

Apply ground-breaking LiDAR technology to acquire and distribute 3D data

Address a broad range of critical applications of national Significance

Provide 3D data including surface elevations and natural and constructed features

3DEP increases the quality level of LiDAR being acquired to enable more accurate understanding, modeling, and prediction

Goal to acquire national coverage in 8 years

PREXXXX 4

BAA Grant Process

What is the 3DEP Elevation Program?

34 federal agencies, 50 states, sampling of local Govt’s, tribes, private and non-profit organizations

Increase investment in 3D data from $45m to $146M annually to return more than $690 million annually in new benefits

Leverage collaboration among Federal, States, local, private and other partners to systematically complete national 3D data in 8 years

Use Private industry mapping firms and create jobs

Achieve 25% cost efficiency gain by collecting larger projects

Refresh National elevation data holdings with new LiDAR

PREXXXX 5

BAA Grant Process

How it works

Stakeholders complete a grant application identifying proposed funding partners and developing a technical approach for a prpoject.

Typically cost per sq mile for QL2 is between $190 and $330

If stakeholder wants higher than QL2 or more products USGS will not contributed to these products but having higher Quality level or more products can’t hurt your award potential and could actually improve it.

Selection can improve if stakeholder contributes more than USGS

Selection is also improved by USGS if other federal agencies have interest in the proposed project area such as – NOAA, FEMA & NRCS.

USGS NGP LBS V1.2

USGS National Geospatial Program Lidar Base Specification Version 1,2 November 2014 (B11-Chapter 4).

Standardize the Data For USGS.

and acceptance into 3DEP( formally

NED ).

• Way to ensure requirements are met.

• LiDAR Data continues to improve

so set specifications to adapt to better

Data.

PREXXXX 12

USGS NGP LBS V1.2

For the data to be included into 3DEP and to have a chance for BAA Funding it needs to be QL2 Data or better.

PREXXXX 13

Swath Repeatability

Why we use Optech Galaxy Sensors

PREXXXX 14

USGS NGP LBS V1.2

Summary of QL2 Specifications

2 points per meter, minimum 90% of cells, First return check

Vertical accuracy is 10cm or better for Non vegetated areas

Vegetated is 29.4cm at 95% confidence level

Accuracy Check Done using ASPRS Positional Accuracy Standards for Digital Geospatial Data v1.0 November 2014

100 meter buffer around project area

Use multi-return sensor

Classification Standards

Data has to be delivered in USGS Coordinates and Datum

NAD83(epoch 2010), NAVD88, Geoid 12A, UTM FEET*

Regularly point samplings (90 % of cells contain at least 1 return)

PREXXXX 15

USGS NGP LBS V1.2

Summary of QL2 Specifications (cont.)

Ground conditions: snow free, Leaf off as best as possible, no flooding or water inundation

Check accuracy of data using calibrated raw Strips

Relative accuracy of the data is 6cm within Swath and 8cm between Swaths, max swath difference 16cm

Data reported in standard GPS time

accuracy reported as NVA points and VVA points based on project size

Data provided in ASPRS LAS1.4 Format

Hydro-flattened and hydro conditioned Breaklines

PREXXXX 16

USGS NGP LBS V1.2

Point Classifications

These are the minimum requirements.

PREXXXX 17

USGS NGP LBS V1.2

Hydro Flattening

Water bodies of 8000m(2) or greater surface area at the time of collection shall be flattened.

Flattened water bodies shall present a flat level water surface

Water-surface edge shall be at or below the immediately surrounding terrain

Long impoundments –such as reservoirs, inlets, fjords, whose water surface elevation decrease with downstream travel will be treated as streams or rivers

Inland streams and rivers of a 30-m (100-ft) nominal width shall be flattened

Streams or rivers whose width varies above and below 30 meters will not be broken into multiple segments.

PREXXXX 18

USGS NGP LBS V1.2

Hydroflattening (cont.)

Flattened streams and rivers shall present a flat and level water surface bank to banks

Flattened streams and rivers will be monontonic displaying downward flow

Note that the new specification may require the Hydro to comply with NHD standards to be used in that data set

PREXXXX 19

USGS NGP LBS V1.2

Tidal Hydroflattening

Any water body that is affected by tidal variations

Within each water body, the water surface shall be flat and level for each different water surface elevation

Vertical discontinuities within the water body resulting form tidal variations during collection are considered normal and shall be retained in the final DEM

Horizontal discontinuities along the shoreline of a water body resulting from tidal variations during collection are considered normal and shall be retained in the final DEM

Islands 4000m(2) (1 acre or larger shall be delineated within all water bodies.
