Background ASPRS Panel recommendations USGS Plan for Quality Assurance of Digital Aerial
Imagery Status and schedule Summary

Why calibration at USGS?
Photogrammetric methods for map generation Map production primarily done in-house Quality assurance measure for aerial photography
from aerial contractors
Leadership role in standards development Unbiased, independent agency with technical
expertise Quality assurance for The National Map
BackgroundBackground

USGS Camera Calibration HistoryUSGS Camera Calibration History
USGS responsible for calibration services for film camera in United States since 1973
USGS operates Optical Sciences Lab (OSL) in Reston, VA with a custom-built calibration instrument
Current policy requires current (within 3 years) camera calibration report on file before award of contract
The “Catch-22” problem for digital sensors
6
Continue to provide analog calibration services Develop and implement digital calibration capabilities Develop standards for camera and sensor calibrations Develop and implement in-situ calibration methods

Stage 1: Initiation Stage 2: Contagion Stage 3: Control Stage 4: Integration
Stages of New TechnologyStages of New Technology
8
Initiation: Research and pilot projects Contagion: Wild enthusiasm and demand Control: Refined standards and format Integration: DOQs critical to enterprise operation
Example: DOQsExample: DOQs

Lack of information: What, where, why, and how? The unknown: Does it perform as claimed? Business decision: Does it make business sense? Lack of experience: What I can or can not do? Operational changes: What are the best practices? Lack of standards: What are the specifications? Overcoming inertia: Acceptance by clients?
The Barriers to New TechnologyThe Barriers to New Technology
10
An independent validation of manufacturer’s specifications
Development and monitoring of “best practices” Standardized procurement specifications Uniform quality assurance measures
The Formula for QualityThe Formula for Quality
11
Development and of a comprehensive quality plan Acceptance and use by Inter-Agency Digital Image
Working Group agencies Requirement by other agencies and contracting
offices Acceptance by general user community

USGS Plan for Quality AssuranceUSGS Plan for Quality Assurance
Four major parts covering two major processes:
Data Production: Manufacturers Certification Data Providers (flyers) Certification
Data Purchasing & Acceptance Contracting Guidelines Data Acceptance Standards

Manufacturers CertificationManufacturers Certification Aerial Digital Imaging is in its “Wild West” phase
Anything & everything being tried Some metric-quality systems Many “other” systems
How does the customer know which can produce mapping-quality data?
USGS to offer “type certification” of mapping-quality digital aerial sensors
Must be stable, well-quantified, repeatable Able to routinely generate mapping-quality data
When operated properly!
17
Communicates specifications Provides evidence of system performance Independent certification helps to promote sensor
systems Supports verification of Data Provider’s system Type certification eliminates burden of calibration for
each sensor sold in the United States (1 time vs. n times)
Eliminates need for USGS to have custom-built calibration instrument for calibration purposes
Benefits of Manufacturers CertificationBenefits of Manufacturers Certification
18
Data Providers CertificationData Providers Certification
Second half of data generation is the flyers/Data Providers’ data processing
USGS to provide Data Providers Certification
Focused on processes and process control Ensures that Data Providers are operating sensors in
accordance with manufacturer’s instructions and limitations Ensures that Data Providers follow quality procedures
Desire to ensure reliability, repeatability, and trust
19
Provides evidence of performance of products Independent certification helps to promote product
specifications and Data Provider’s capabilities Documents Data Provider’s quality assurance plan
and “best practices” One certification for Data Provider and not for each
camera Data Providers no longer have to send cameras to
OSL for calibration, reducing down-time and shipping expenses
Benefits of Data Providers CertificationBenefits of Data Providers Certification
20
Contracting GuidelinesContracting Guidelines
User community is not sure how to contract for digital imagery
New terms, capabilities, standards, lexicon Inhibits digital contracting Addresses boilerplate requiring “USGS Certificate” Goal is to remove barriers to digital aerial contracts Encourage digital imaging
Created Federal Digital Imagery General Contract Guideline
21
Standardized terms and descriptions make the contracting process easier and more uniform among agencies
Guidelines help acceptance of digital sensors and educate end-users on benefits of digital technology
Standardized terms and guidelines help contracting officers describe their users needs
Standardized performance measures USGS certifications provide a priori acceptance of
systems and Data Provider’s “best practices” Manufacturer and Data Providers Certification reduces
necessary documentation in the RFP process
Benefits of Contracting GuidelinesBenefits of Contracting Guidelines
22
Digital Data Acceptance StandardsDigital Data Acceptance Standards
End-users unsure of how to judge digital aerial data quality
New terms & capabilities (resolution, spectral, etc.) Each customer understands things differently
There is a need for common, uniform definitions and methods for evaluating quality of image data
USGS to work with Inter-Agency Digital Image Working Group to develop these standards
Goal is a Web-based tool illustrating quality problems, measurement techniques, and standards
23
Data consumers have common standards to evaluate data products
More consistent acceptance/rejection criteria among contracting agencies
Clearer standards and guidelines helps to eliminate false expectations
Ensures high quality products Increases customer satisfaction
Benefits of Acceptance StandardsBenefits of Acceptance Standards
24
Manufacturers Certification (Cost-shared by USGS and manufacturers)
Data Providers Certification (100% by Data Providers)
Contracting Guidelines (100% USGS and IADIWG funded)
Acceptance standards (100% USGS and IADIWG funded)
Funding StrategyFunding Strategy
25
Manufacturers Certification Guidelines in work now Up to 4 manufacturers to be certified this fiscal year Two factory visits completed; reports pending Four Data Providers have expressed interest working
on the initial round of Data Providers Certification First draft of Digital Imagery Contracting Guideline
completed and reviewed by limited group A Web-based tool to help generate contracting language is
being developed
StatusStatus
26
My personal opinion Thanks for the cooperation Cost-benefit Taking the high ground Factory visit completed, report in-progress Another opinion (Suppliers, testing, and quality
control) A few details, but no issues Type certification on DMC will be issued
Intergraph Manufacturers CertificationIntergraph Manufacturers Certification
27
USGS Plan for Quality Assurance of Digital Aerial Imagery briefed during ASPRS panel session
Invite comment from broader community Finalize and obtain ASPRS approval Begin initial Data Providers Certifications Provide briefings to geospatial community Participate in international forum to communicate
plans in United States
Next StepsNext Steps
28
Four Phases of Technology Assimilation:
Phase 1: Identification and investment Phase 2: Learning and adaptation Phase 3: Rationalization and management control Phase 4: Maturity and widespread acceptance
Closing ThoughtClosing Thought
29
To implement a comprehensive, meaningful process that ensures the quality of data products and services
To cooperatively develop the plan with all elements of the geospatial community
Education and training also a major component
Good for one is good for all
To establish a model to support new technologies
