BMGS STRATEGIC GOALS
1.
Clients achieve their
objectives through
convenient access to
integrated information
2.
Clients receive base
mapping that meets their
needs in terms of core
features and update cycles
3.
Further the use and
integration of provincial
base mapping in all sectors
of the economy
4.
Clients engage BMGS as a
Center of Excellence for
geomatic technology
ISO 9001:2000
Development of Specifications
and the Community of
Practice responds to goals
through:
 working with stakeholders to
identify business
requirements & strategies
 piloting update process
 evaluating results
 making proposals for changes

SPECIFICATIONS – Please !
Why were specifications required?
 New, emerging technologies were seen as viable
tools
 Medium format digital cameras
 LiDAR
 Soft copy A/T, auto correlation and INS/IMU
 Clients wanted faster end to end turn around
 Promising tools but technical issues
 BMGS – needed to establish leadership to avoid
random adoption
 Change focus to results as opposed to
prescriptive process

SPECIFICATIONS CONTENT
What was required in the specification content?

Clearly defined deliverables for:
 Digital air photo and Orthophotos
 LiDAR
 A/T

Standards for calibration of:
 non-metric cameras
 LiDAR calibration
 Q/A – Q/C processes

A software packages that are readily available to all
contractors

Meta Data standards

LiDAR SPECIFICATIONS
CONTENT
Specifics for the LiDAR specification content
 LiDAR is not an “open” system” – required a different approach
 A simple means of determining potential system accuracy
through error propagation formula
 Use material from others – FEMA, ASPRS, USGS
 Define a QA/QC process


ISO 9001:2000
Require calibration and reports
Require data processing methodologies

Building “buy-in”
Engage academia, clients, producers and data custodians
Build operational specifications
Move research from academia into industry
Specifications development from a project manager perspective
 Create environment of shared knowledge and cooperation

What is the definition
of a
Large Format Camera?
Large Format Camera
The Large Format Camera (LFC) was a high altitude aerial mapping camera scaled up to operate from
the Space Shuttle. It was used on one mission in October 1984
The camera weighs about half a ton and a single frame covers 23,400 square
miles at about 10-20 m resolution.
