Dhaka, Bangladesh: Survey of Bangladesh (SOB) will complete detailed digital topography map of Bangladesh by 2016, according to the Director of SOB, Colonel Mahmudun Nabi. He claimed that this is the first time a digital topographic map is being done to provide ‘accurate and detailed’ information on Bangladesh. “Once completed, it will help the government as well as the people,” he told a group of journalists at his office.
A topographic map is a detailed and accurate graphic representation of cultural and natural features on the ground. As a sole national topographic mapping authority, the SOB started the BDT 1.81 billion (Bangladeshi Taka: BDT) project at the end of 2007 with technical and financial support from Japanese International Cooperation Agency (JICA).
“It’s a huge task. We didn’t have any previous experience. Our staff were trained in Japan and Thailand,” the director said and added that they captured aerial photographs and gathered satellite images of the inaccessible areas.
The national map will be produced at a scale of 1:25000. The conventional one is at a scale of 1:50000 composed by the British government. Separate 1:5000 scale digital topographic maps will be drawn for five divisional cities –Barisal, Chittagong, Khulna, Rajshahi and Sylhet.
Chief adviser of JICA Expert for Public Survey Administration Bokuro Urabe said Bangladesh could have saved BDT 3.74 billion in planning costs from 2010-11 Annual Development Programme if it had national standard maps.
