This document discusses Lean, Six Sigma, and Lean Six Sigma approaches to mapping production. Lean aims to increase productivity by eliminating waste like excess imagery and improving speed and quality. Six Sigma uses a DMAIC process to decrease defects by defining metrics, measuring performance, analyzing sources of errors, improving processes, and controlling quality. Lean Six Sigma integrates these methods to achieve better results than either alone. For mapping production, Lean Six Sigma could help by engaging people, defining appropriate metrics, and analyzing sources of errors and waste to continuously improve processes and quality.

2. Mapping Production
Geographical Information System (GIS) industry – extremely broad
 Best example is Google Earth…
 Aerial Mapping
 https://www.youtube.com/watch?v=OPUQooxy9yk
 Examples:
 Governments use aerial imagery to help monitor and manage
environmental change
 Local governments use aerial imagery to improve town planning
 Mining companies use aerial imagery to help quantify and manage
disturbance and rehabilitation
 Engineers rely on aerial imagery to help determine optimal route location
and design for major infrastructure projects
 Emergency services rely on rapid-response aerial imagery to help assess
damage caused by natural disasters and plan future mitigation strategies.

3. Ortho Photo Production
INPUTS ORTHO Production
 Flying (capturing)
 Surveying
 Other inputs
 DTM
 GSD
 Flight info
 Type of camera
 Image Preparation
 Aerial Triangulation
 Digital Elevation
Modelling (DEM)
 Ortho Photo processing
 Image Editing
 Delivery

4. Implementing Lean Production
Jeyaraman & Teo - “the primary goal to introduce any lean production program
in a shop, factory or company is to increase productivity”
Problem Solution
Estimate Waste • Excess Imagery • Flight planning
enhancements
Increase Speed and
response
• Hardware / Software
• Data management
and speed
• Better software
• Increase licensing
• New technology
• Training
Improve Quality • Lack of quality control • Establish control
check points (control
charts)
Reduce Cost • Project knowledge
• Communication flow
• Enterprise system

5. Six Sigma – using DMAIC
Gutie´rrez - “Six sigma attempts to decrease the number of defects that
appear in different organisational processes”
 Define
 Metric definition
 Hours
 Re-work hours
 Measure
 Hours booked against projects
 Pareto Analysis (80/20)

 IQA & FQA

10. Lean Six Sigma (LSS)
 What is LSS?
Antony – “the integration of two methodologies can achieve better results
than either method could achieve alone. While Lean strategies play an
important role in eliminating waste and non-value added activities across the
organisation, Six Sigma, through the use of statistical tools and techniques,
takes an organization to an improved level of process performance and
capability.”
 Why use LSS on mapping production?
 People
 Metrics
