PCI Geomatics Delivers Historical Airphoto Processing System in Sabah, Malaysia

by | Nov 13, 2013

RICHMOND HILL, Ontario, Canada, Nov. 7, 2013”PCI Geomatics, a world leading developer of geo-imaging software and systems, today announces that it has successfully delivered to the Sabah Lands and Surveys Department (SLSD) a Historical Airphoto Processing (HAP) system, a customized workflow developed by PCI Geomatics. Installation and training, which took place in September of this year, were included in the delivery of the system.

Sabah, one of 13 member states which comprise Malaysia, is located on the northern portion of the island of Borneo, and has a total land area of 73,631 km2. The Sabah Lands and Surveys Department has secured the use of a HAP system within its organization in order to produce seamless ortho mosaics for the over 40,000 historical images it possesses in its archive “ dating from the 1970's, 1980's, 1990's and 2000's.

The Sabah Lands and Surveys Department received onsite training from PCI's HAP experts who travelled to Kota Kinabalu, the capital of Sabah, in order to install and provide training. Using an iterative approach and leveraging automated Ground Control Point collection techniques, large blocks of images from the archives were successfully orthorectified, and mosaicked.

Previously, historical images were made available to the public through the SLSD central office location in Kota Kinabalu, however this only provided limited use of the imagery. By proactively correcting all of the imagery from the various years, the SLSD will be significantly increasing transparency for key issues that deal with land ownership, natural resources, and change detection dating back to the 1970's.

Prior to implementing the Historical Airphoto Processing System, the distribution of imagery was limited to onsite consultation in our offices, said Robert Cheng, Assistant Director of Survey & Mapping. The HAP system will allow us to produce highly accurate, color-balanced orthorectified digital mosaics that can be consulted through our Sabah Land Information System (SALIS), through the Internet.

We are pleased to see that this valuable source of imagery will be preserved and will continue to provide value to its owners, and to the citizens of Sabah, said Wong Tai Hong, General Manager at, Jurupro SND BHD, PCI's Reseller in Malaysia. The customer was impressed with the HAP system's capability and immediately identified a need to use the system to process imagery in their archive in order to preserve its value, he added.

PCI Geomatics recently introduced the Historical Airphoto Processing Workflow, which leverages the Geomatica platform to produce ortho-mosaics from difficult-to-process scanned historical imagery. The system is successfully being used in Canada, the US, Europe, the Middle East and Asia.
