SOB makes digital maps for country's geo-information

Participants tell seminar

Staff Correspondent
The Survey of Bangladesh (SOB) with the help of Japan is implementing a digital mapping system project to prepare countrywide baseline map.
The SOB has already completed a digital map for the capital while the digital maps for other metropolitan cities Chittagong, Khulna, Sylhet, Rajshahi and Barisal will be completed very soon.
This was stated by the participants at a seminar titled 'Geoinformation and digital mapping in Bangladesh: Present and future' organised by the SOB at a city hotel.
The speakers said the SOB is implementing the six-year-long project beginning from 2007 to modernise the mapping system by introducing 1: 25000 scale topographic database instead of 1: 50000 scale.
Around 50 government organisations, 60 private survey companies, 15 departments of public and private universities, some research organisations from home and abroad and non-government organisations are involved in the project.
Speaking as chief guest, LGRD Adviser Mohammad Anwarul Iqbal said geo-information is one of the crucial primary data sources for analysing and planning for critical national issues of development,
disaster management, adaptability and resilience to climate change.
"In the present perspective of global climate change, Bangladesh is the worst victim of natural disasters like cyclone, drought, recurrent floods and sea level rise. Geoinformation technology can be helpful in this regard,” he added.
Brig Gen M Habibur Rahman Khan, surveyor general of Bangladesh, said the SOB can produce hardcopy paper map of 1:25k for the entire country and 1:5k for five divisional cities after establishing geo-database.
"All the government and nongovernment organisations will have the same mapping standard and access to geo-database, digital elevation model and contour information for the whole country," he added.
Lt Col Mohammad Alauddin, project coordinator and director of defence survey, said the digital mapping will be used for disaster preparedness and prevention of natural calamities.
"Tidal information from the tidal gauge will be used for monitoring sea level rise and predicted Tsunami and potential coastal inundation due to global warming. Private transportation agencies including land, river and air, police, Rapid Action Battalion and other intelligence agencies will be able to integrate topographic database in
its vehicle and criminal tracking system," he added.
Defence Secretary M Kamrul Hasan and Japanese Ambassador in Dhaka Masayuki Inoue also addressed the seminar.
