Survey Preview - 3D Nation Elevation Requirements and Benefits Study
3D Nation Requirements and Benefits Study
OMB Control Number: 0648-0762
Expiration Date: 05/31/2021
INTRODUCTION
The U.S. federal agencies involved in terrestrial, ocean and coastal mapping are gathering information to improve the availability
and consistency of 3D elevation data for the United States and its territories. The National Oceanic and Atmospheric
Administration (NOAA) and the U.S. Geological Survey (USGS) are sponsoring the study. The results of the study will help
agencies develop and refine future program alternatives for better 3D elevation data to meet many federal, state, and other
national business needs.
For purposes of this questionnaire, 3D elevation data refers to topographic data (precise three-dimensional measurements on
land) and bathymetric data (precise three-dimensional measurements in the water). Questions will be asked about how elevation
data relates to your specific Mission Critical Activities (activities that are indispensable for mission accomplishment and/or
essential for effective/efficient operations in accomplishing the core mission of the organization). The questionnaire also explores
where you need elevation data (geographic extent), the accuracy and update frequencies you require, and your assessment of
how your organization would benefit from better elevation data.
A Federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a
penalty for failure to comply with an information collection subject to the requirements of the Paperwork Reduction Act of 1995
unless the information collection has a currently valid OMB Control Number. The approved OMB Control Number for this
information collection is 0648-0762. Without this approval, we could not conduct this survey/information collection. Public reporting
for this information collection is estimated to be approximately 2 hours per response, including the time for reviewing instructions,
searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the information
collection. All responses to this information collection are voluntary. Send comments regarding this burden estimate or any other
aspect of this information collection, including suggestions for reducing this burden, to the NOAA Office of Coast Survey, attention
Ashley Chappell ([email protected] or 1315 East-West Hwy, Silver Spring, MD, 20910.)
Your response to this survey is voluntary. We will aggregate responses at the agency, state, and national levels. We will not
distribute responses associated with you as an individual. We ask you for some basic organizational and contact information to
help us interpret the results and, if needed, to contact you for clarification. Notwithstanding any other provisions of the law, no
person is required to respond to, nor shall any person be subjected to, a penalty for failure to comply with a collection of
information subject to the requirements of the Paperwork Reduction Act, unless that collection of information displays a currently
valid OMB Control Number.
The 3D Nation Study
We would like to thank you in advance for participating in the 3D Nation Requirements and Benefits Study. This questionnaire
covers a wide range of business uses that depend on 3D elevation data to inform policy, regulation, scientific research, and
management decisions. By learning more about your business uses (see FAQ #1) and associated benefits that would be realized
from improved 3D elevation data, we will be able to prioritize and direct investments that will best serve user needs.
The questionnaire includes questions about the technical requirements for 3D elevation data as well as questions about the
benefits of 3D elevation data to your organization. The technical requirements may best be answered by an elevation data user
who has experience working with the data. The benefits questions may best be answered by a stakeholder or person who makes
management or business decisions. If applicable, the questionnaire may be jointly completed by an elevation data user and
stakeholder in order to capture both perspectives for a Mission Critical Activity. We expect the findings to help characterize and
value national business needs for 3D elevation data and associated technologies. This information will help NOAA, USGS, and
other Federal agency programs better meet stakeholder needs and fulfill their mapping mandates (see FAQ #2). The data will
inform the design of future programs that balance requirements, benefits, and costs of elevation data at a national scale.
The results will also help to unite terrestrial and coastal/ocean mapping efforts for a true 3D Nation, from the highest mountains to
the deepest oceans, to ensure public access to an accurate, authoritative national elevation dataset.

Instructions
● Please answer the questions from the perspective of your organization, not yourself personally.
● The responses to the questions are in two formats – open-ended and structured response.
o Please enter responses to the open-ended questions in the text box below the questions.
o For the structured response questions, use the drop-down or check boxes to choose the best response(s) for your
organization and data uses.
● We recommend that you first review two tutorials for background and context:
o A list of frequently asked questions (FAQs) on 3D elevation data terms used throughout the questionnaire. Even if all the
terms in the FAQs are familiar to you, reviewing this material will help ensure that all participants have the same definitions in mind
when answering the questions.
o Examples of benefits that an organization might gain from improved topographic and/or bathymetric information. These
benefits are organized into three categories: (1) Operational, (2) Customer Service, and (3) Societal Benefits. The tutorial also
demonstrates methods for estimating monetary benefits, as we do have a few questions on this, among other types of benefits.
● Although we do not expect you to take a great deal of time researching the response for each question, you may exit the
questionnaire and return at a later time. If you complete a response for a Mission Critical Activity, you may also return to the
survey and complete a new entry for a new Mission Critical Activity.
● Some hints and suggestions from our survey pre-testers include:
o The survey instrument seems to work faster on Internet Explorer than Google Chrome.
o We do not recommend taking the survey on a mobile device.
o Hitting the Enter key in an open text box submits the survey and brings you back to the survey start page; instead, provide
input and then move to the next question or hit Save or Next.
o You may return to the survey at any time using the link provided to you when you save and exit, to complete questions or
add new Mission Critical Activities. Check your Spam folder if you request the system to email you the link but don't receive it.

Question 23. The following series of tables apply to the FUTURE benefits that your program would gain from
inland 3D topographic elevation data if ALL of the requirements you provided above could be met for the
selected Mission Critical Activity. The future benefits are broken into three main categories: Operational,
Customer Service, and Societal, and then into subcategories (e.g. Time savings, Cost Avoidance, etc). Each
subcategory contains potential types of benefits. If you have another category and/or type of benefit not
provided below, please write in your own response. See benefits document.
For each benefit type please indicate the following:
● Benefits your program is likely to receive - Select the option that most closely describes the magnitude of
benefits your program is likely to receive for each benefit type on a scale from ‘None’ to ‘Major’ ‘Don’t know’ is

benefits your program is likely to receive for each benefit type, on a scale from ‘None’ to ‘Major’. ‘Don’t know’ is
also an option.
● Quantification of Benefits - Please quantify any operational and/or customer service benefits you are likely to
receive. Each benefit subcategory has its own quantification metric (e.g. Time Savings is type of hours saved
(annual or monthly) and amount of those hours saved (e.g. 80)).
● Briefly Describe the Benefit
1. Briefly describe any major benefits. A few examples are provided as follows: fewer field visits would be
required, or having authoritative data readily downloadable from a single site would save work hours, or
we could perform more accurate and efficient modeling, or improved data would improve our ability to
protect critical habitat areas.
2. For benefits you quantified, also briefly describe how you quantified the benefit. For example: fewer field
visits would be required, 2 hours/field visit for 200 fewer field visits a year = 400 annual hours saved.

Question 35. The following series of tables apply to the FUTURE benefits that your program would gain from
inland 3D bathymetric elevation data if ALL of the requirements you provided above could be met for the
selected Mission Critical Activity. The future benefits are broken into three main categories: Operational,
Customer Service, and Societal, and then into subcategories (e.g. Time savings, Cost Avoidance, etc). Each
subcategory contains potential types of benefits. If you have another category and/or type of benefit not
provided below, please write in your own response. See benefits document.
For each benefit type please indicate the following:
● Benefits your program is likely to receive - Select the option that most closely describes the magnitude of
benefits your program is likely to receive for each benefit type, on a scale from ‘None’ to ‘Major’. ‘Don’t know’ is
also an option.
● Quantification of Benefits - Please quantify any operational and/or customer service benefits you are likely to
receive. Each benefit subcategory has its own quantification metric (e.g. Time Savings is type of hours saved
(annual or monthly) and amount of those hours saved (e.g. 80)).
● Briefly Describe the Benefit
1. Briefly describe any major benefits. A few examples are provided as follows: fewer field visits would be
required, or having authoritative data readily downloadable from a single site would save work hours, or
we could perform more accurate and efficient modeling, or improved data would improve our ability to
protect critical habitat areas.
2. For benefits you quantified, also briefly describe how you quantified the benefit. For example: fewer field
visits would be required, 2 hours/field visit for 200 fewer field visits a year = 400 annual hours saved.

Question 48. The following series of tables apply to the FUTURE benefits that your program would gain
from nearshore 3D bathymetric elevation data if ALL of the requirements you provided above could be met for
the selected Mission Critical Activity. The future benefits are broken into three main categories: Operational,
Customer Service, and Societal, and then into subcategories (e.g. Time savings, Cost Avoidance, etc). Each
subcategory contains potential types of benefits. If you have another category and/or type of benefit not
provided below, please write in your own response. See benefits document.
For each benefit type please indicate the following:
● Benefits your program is likely to receive - Select the option that most closely describes the magnitude of
benefits your program is likely to receive for each benefit type, on a scale from ‘None’ to ‘Major’. ‘Don’t know’ is
also an option.
● Quantification of Benefits - Please quantify any operational and/or customer service benefits you are likely to
receive. Each benefit subcategory has its own quantification metric (e.g. Time Savings is type of hours saved
(annual or monthly) and amount of those hours saved (e.g. 80)).
● Briefly Describe the Benefit
1. Briefly describe any major benefits. A few examples are provided as follows: fewer field visits would be
required, or having authoritative data readily downloadable from a single site would save work hours, or
we could perform more accurate and efficient modeling, or improved data would improve our ability to
protect critical habitat areas.
2. For benefits you quantified, also briefly describe how you quantified the benefit. For example: fewer field
visits would be required, 2 hours/field visit for 200 fewer field visits a year = 400 annual hours saved.

Question 60. The following series of tables apply to the FUTURE benefits that your program would gain
from offshore 3D bathymetric elevation data if ALL of the requirements you provided above could be met for the
selected Mission Critical Activity. The future benefits are broken into three main categories: Operational,
Customer Service, and Societal, and then into subcategories (e.g. Time savings, Cost Avoidance, etc). Each
subcategory contains potential types of benefits. If you have another category and/or type of benefit not
provided below, please write in your own response. See benefits document.
For each benefit type please indicate the following:
● Benefits your program is likely to receive - Select the option that most closely describes the magnitude of
benefits your program is likely to receive for each benefit type, on a scale from ‘None’ to ‘Major’. ‘Don’t know’ is
also an option.
● Quantification of Benefits - Please quantify any operational and/or customer service benefits you are likely to
receive. Each benefit subcategory has its own quantification metric (e.g. Time Savings is type of hours saved
(annual or monthly) and amount of those hours saved (e.g. 80)).
● Briefly Describe the Benefit
1. Briefly describe any major benefits. A few examples are provided as follows: fewer field visits would be
required, or having authoritative data readily downloadable from a single site would save work hours, or
we could perform more accurate and efficient modeling, or improved data would improve our ability to
protect critical habitat areas.
2. For benefits you quantified, also briefly describe how you quantified the benefit. For example: fewer field
visits would be required, 2 hours/field visit for 200 fewer field visits a year = 400 annual hours saved.

Survey Preview - 3D Nation Elevation Requirements and Benefits Study
If you have additional Mission Critical Activities that require 3D elevation data, please use the same survey link provided to you
and repeat the questionnaire for any additional Mission Critical Activities you have.
Thank you for responding to this 3D Nation Elevation Requirements and Benefits Study questionnaire. The information that you
have provided will be summarized for the Federal Agency, State, Territory, Tribe, or non-governmental organization that you
represent. The Point of Contact for your organization will then have an opportunity to review and edit the summary requirements
that will feed into the final 3D Nation study report. The final study report will be the primary source of information used to develop
recommendations for a 3D Nation, which unites terrestrial and coastal/ocean mapping efforts from the highest mountains to the
deepest oceans to ensure public access to an accurate, authoritative national elevation dataset. If you have any comments about
the 3D Nation please contact: [email protected] or [email protected].
