The advantages of digital field data collection in the GIS environment. Malaysian Geospatial Conference Malacca 6-7 March 2012 Ray Chung APAC Regional Manager – Trimble Navigation
The big question: Where do we need improvements? Where are our assets? “WHERE?” Where are our vehicles & equipment? Where did we get this information? Where are our field workers?
GIS Data Collection Solutions • Systems designed specifically for location-based field work: • Data collection • Asset management • Inspection • Professional-grade GNSS in the hand for GIS applications • Communications • Cameras with geotagging • High-visibility touch screens • Software and unique technologies for better productivity
Adding value to GIS • Organisations utilise GIS to make critical decisions • But where is the data coming from?
If GIS data collection is worth doing, it’s worth doing right.
Whitworth Water District, USA • The Problem: • Finding the toby locations in emergency situations • Buried assets – more difficult to find under snow or in large expanses of land • Old Way • Memory! • Hand-drawings • Nearby many water meters – drawn relative to meter • Not to scale or updated since • Use map to get 'close' and metal detector and shovel to find valve.
Whitworth Water District, USA • Workflow • Locate and collect curb stops with high accuraccy • QA/QC performed on site • Waypoint files created and used for service calls • Spreadsheet for address/ID lookup • Navigate to curb stop valve • +/- 100mm in most cases • Update the GIS after work is performed
Africa Conservation Trust, South Africa • The Problem: • Information required to monitor gardens related to food security • Old Way • Combination of paper forms, separate GPS, camera (digital photos) • New Way: Trimble Solution • Municipal Reporter system utilising variousTrimble platforms • Juno, Yuma + ProXT • Laser rangefinder
Africa Conservation Trust, South Africa • Workflow benefits • “Faster and more efficient data capture which has saved on time in the field and time in the office.” • Saved the cost of one worker
Data Integration Data Integration Overall Cost Field Work Field Work Capital Costs Capital Costs Trimble Workflow Pen & Paper Workflow
Metropolitan Electricity Administration • Bangkok, Thailand • 20%-30% of all errors are attributed to transcribing field workers data sheets by data entry personnel! • Reasons – unable to read writing, understanding and transferring diagrams, technical and personal jargon and abbreviations
