3DEP Growth Strong coordination and increasing investments (FY13-16)
6.7% of the lower 49 and territories was acquired in FY16 - 32% increase in investment and
43% increase in square miles acquired over FY15 level
3DEP data have been contracted for 26% of the entire US (lidar between FY13-16 and IfSAR
between FY10-16)

3DEP National Multiyear Plan Background
■ 3DEP Executive Forum tasked the 3DEP
Working Group to develop plan to:
■ Move from an annual, opportunistic process
to a unified multi-year plan
■ Move from patchwork irregular acquisition
footprints to a defined planning and delivery
unit
■ Implement a phased approach beginning in
FY18
■ Benefits
Facilitate greater investments and leveraging
through longer planning lead times
Defined units facilitate planning and
understanding costs, allow for improved
reporting and justification of investments
Presents a plan for nationwide coverage
Move from this…
…to something more like this

3DEP National Multiyear Plan 3DEP Working Group Goals
■ Identify and document plans of Federal agencies to acquire 3DEP data,
distinguishing between funding plans vs. areas of interest
■ FY18 – collect Federal plans, initially for 2 years; not all agencies are
positioned to participate, but a few key agencies have agreed to do so
■ Outyears – work towards planning for national coverage over multiple years
■ Develop a cost share model for Federal investments
■ Determine Federal investments on a state-by-state basis
■ Overall concept is 2/3 Federal and 1/3 state funding across the nation, but
ratios will vary depending on presence of Federal lands and other Federal
data needs in each state
■ National Plan made up of 50+ State Plans - Work with States and other non-
Federal partners to develop joint state-based plans to leverage Federal and non-
Federal funds to complete national coverage
■ Manage the collective plans and program information on the GeoPlatform and
Elevation Community pages

3DEP National Multiyear Plan Costshare considerations
■ Amount of Federal land – for example, land management agencies provide 50%
and USGS 50% of costs
■ Amount of private agricultural land – guides NRCS investment
■ Amount of high, moderate and low risk areas – guides FEMA investment
■ Under discussion
■ How to include other Federal agencies
■ How to use USGS funding to fill in gaps
■ Hitting the right balance, keeping non-fed share fair/justifiable

Current Funding Split
On the whole, within range of 2/3 Federal 1/3 Non-Federal costshare
Investments split between BAA (fair and equitable competitive process
for non-Federal partners to receive Federal support) and other
partnerships (mostly Fed-to-Fed)
Multiyear state plans will help unite BAA and other partnerships into a
unified approach

3DEP National Multiyear Plan
Lidar costs are dynamic – good news is that costs are going down!
New technologies like geiger mode and single photon lidar will change the
cost structure – but we don’t yet know the full lifecycle costs including
processing and storage
3DEP keeps tabs on costs and seeks continual improvement
Average cost per square is calculated and reported in the 3DEP annual report –
based on both GPSC and cooperative projects
We need to validate data from vendors proposing significantly lower costs or new
technologies – consistent quality is critical to national coverage
Goal is to use new tiling scheme to develop multiple terrain-based cost estimates
to replace the national average – to help cost planning
Cost Planning Considerations
+ 12 + 12
3DEP National Multiyear Plan
■ Recommendation is to use an adapted version of the
“Albers1kTiles” schema (1 km x 1 km tiles)
■ Benefits
■ 1 square km is small enough to approximate watersheds, county
and state boundaries, etc., without adding excessive area to
projects
■ Tile sizes are equal in area no matter their location in latitude or
longitude
■ Avoids slivers and unnecessary overlap between projects and
more orderly approach to nationwide coverage
■ Recommendation and next steps will be discussed at the 8
PM session – please join the conversation!

3DEP National Multiyear Plan
■ Potential mechanisms
■ 3DEP State Plan Task Force
■ Existing elevation committees
■ Coordination with update to NEEA requirements and benefits
■ Goal to be public and inclusive
■ Public meetings sponsored by NSGIC/the State and USGS via the liaison
■ National webinars to provide information to all stakeholders
■ Work with AASG as the other state group in the 3DEP WG
■ Other options
■ Potential project with NSGIC
■ Jointly develop template(s) for state plans
■ Support for states to participate in developing plans
■ Develop and implement pilot state projects
■ Help to identify authoritative POC/champion for NEEA update

Multiyear Plan Implementation
Timeframes depend on how processes mature and resources are put in
place to move towards nationwide coverage
Phased approach
Opportunistic Transitional Fully Systematic
FY16/17 funding level Increased funding Reach full funding
Federal AOIs do not
distinguish areas to be funded
Federal plans distinguish areas
to be funded for a few key
agencies
Federal plans distinguish areas
to be funded for all agencies
Custom/irregular projects Start to use tiling scheme Full use of tiling scheme
Costshare determined on
case-by case basis
Start to change to a more
predictable cost model
Standard cost model in full use
BAA and Fed-only investments
are independent
State plans incorporating both
Federal and non-Federal
inputs begin to be piloted
State plans fully drive joint
investments
Fully Systematic FY21? - on
Opportunistic Approach FY15 - 17
Transitional State FY18 - 20?

3DEP National Multiyear Plan
■ Future 3DEP collections should be planned using an adapted version of the
“Albers1kTiles” schema
■ Albers Equal Area projection (EPSG:6350), XYZ units in meters
■ Each tile is 1 square km in area
■ A standard national tiling naming convention that represents the XY location for
each tile, for ease of searching
■ Tiles can be grouped or block nested by various attributes (counties/states/HUCs),
but each tile should be part of one and only one group (1:1 relationship)
■ Benefits
■ 1 square km is small enough to approximate watersheds, county and state
boundaries, etc., without adding a lot of area to projects
■ Tile sizes are equal in area no matter their location in latitude or longitude
■ Avoids slivers and unnecessary overlap between projects and more orderly approach
to nationwide coverage
Recommended National Tiling Scheme
+ + 18
3DEP National Multiyear Plan
■ A minimum number and acceptable configurations of tiles needs to be determined to
avoid “tile slivers” between projects and inefficient project boundaries
■ A nested block tiling scheme/naming convention needs to be built around “TileID”, so
that tiles can be grouped together for larger-area acquisition purposes
■ A “State” field for each 1k x 1k tile, grouping tiles into states
■ A “County” field for each 1k x1k tile, grouping tiles into counties
■ A “HUC_12” field for each 1k x1k tile, grouping tiles into HUCs
■ Each tile should have one and only one State/HUC/County ID, by majority intersection
■ U.S. islands and territories - Establish a 1k x 1k tiling scheme; each can be an
independent group of tiles and does not need to be in Albers Equal Area, but
whatever equal area projection makes the most sense for each island
■ Categorize tiles into terrain types to develop multiple cost estimates to replace the
nationwide average cost estimate
