BMGS STRATEGIC GOALSBMGS STRATEGIC GOALSBMGS STRATEGIC GOALSBMGS 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

Development of Specifications and the Community of Practice responds to goals through:

working with stakeholders to identify business requirements & strategies

piloting update processevaluating resultsmaking proposals for changes




Part II – Specifications Development

Areas of activityWhy were specifications requiredWhat was required in the specification contentApproach used for development of specificationsWhere Base Mapping and Geomatic Services is atNext steps


AREAS OF ACTIVITYAREAS OF ACTIVITYAREAS OF ACTIVITYAREAS OF ACTIVITY

Medium Format Digital cameras

LiDAR

Aerial Triangulation (A/T)

Orthophotos


SPECIFICATIONS – Please !SPECIFICATIONS – Please !SPECIFICATIONS – Please !SPECIFICATIONS – Please !

Why were specifications required? New, emerging technologies were seen as viable

toolsMedium format digital camerasLiDARSoft 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 CONTENTSPECIFICATIONS CONTENTSPECIFICATIONS CONTENTSPECIFICATIONS 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 LiDAR SPECIFICATIONS CONTENTCONTENT

LiDAR SPECIFICATIONS LiDAR SPECIFICATIONS CONTENTCONTENT

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 Require calibration and reports Require data processing methodologies


DEVELOPING DEVELOPING SPECIFICATIONSSPECIFICATIONS


Approach used to develop specifications

Community of Practice (CoPs) 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

Where Base Mapping and Geomatic Services is at Specifications completion status:

Med. Format Digital Camera (MFDC) published LiDAR published A/T published

Pilot projects An area was flown using the draft specifications for MFDC LiDAR– now using some test data Multiple A/T testing using expert knowledge


NEXT STEPSNEXT STEPSNEXT STEPSNEXT STEPS



Colour Range is very subjective,So which image would best serve the multi-use needs of Clients.



What are the Next Steps? Continue the Community of Practice

Address colour chip issues

Integrate digital and film specifications

Simplify and consolidate Continue to evaluate performance and specification

requirements Continue to work with clients to meet their needs



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 1984The camera weighs about half a ton and a single frame covers 23,400 square miles at about 10-20 m resolution.
