Customer Profile

The Land Survey Department of the government of India is responsible for the publication, printing, and preservation of maps for the state of Tamil Nabu in southeastern India.


No one understands the importance of accuracy, speed and precision more than the employees of the Land Survey Department in Chennai, India. Especially now since the government requires all land records and data to be digitized.


Located in the state of Tamil Nadu, in the southernmost part of the Indian peninsula, the Land Survey Department is responsible for the preservation, publication and printing of land maps and survey documents. According to Mr. T. Saravanan Thangaraj, manager of the Chennai office, this is no easy task.


“The Indian government is sponsoring a project to computerize all land records,” explains Saravanan Thangaraj. “The purpose is to give land administrators, planning authorities, and citizens more and easier access to land data and details.


”A large part of the digitization process requires scanning thousands of maps, drawings and survey documents and records – many of which are over a hundred years old, and irreplaceable.


“We scan over 200 A1-size black-and-white and color drawings per day and some of these documents are extremely fragile,” explains Saravanan Thangaraj. “Many drawings are on film, and some are on tracing paper so it’s crucial that we handle the documents carefully, even though we are on a very tight time schedule.


” It’s important that these fragile materials are not damaged during the scanning process, and equally challenging for the Land Survey Department to provide the highest quality reproductions.


Not only do these documents serve as permanent records and documentation, many of these maps, drawings, and documents are printed and used by villagers, land development authorities and planners to determine boundaries and property ownership. The slightest discrepancy or misunderstanding can cause delays and problems for everyone involved. Therefore, every line, note, mark and letter must be recorded and visible in the final reproduction.


This was especially difficult for the employees at the Land Survey Department as some of the documents they scan are old, worn, faded and folded.


“We needed a scanner that could handle these fragile documents delicately but fast – while still picking up even the tiniest detail,” says Saravanan Thangaraj.


After evaluating many different types of scanning solutions, the Land Survey Department in Chennai, India chose a Contex HD scanner to handle their scanning project.


“We were looking for superior image quality and that’s what we got with the Contex HD scanner,” continues Saravanan Thangaraj.


An important factor for selecting the Contex HD scanner was their need for background cleaning and color separation for very old drawings to keep them.


Benefi ts from day one

The Land Survey Department started using the Contex scanners in 2009 and the benefits were obvious from day one. As many different people in the department are scanning documents, it was important that the scanner was easy to set up and use.

According to Mr. Saravanan Thangaraj, the Contex scanners fit the bill perfectly. “We were up and scanning quickly with very little set-up required,” says Saravanan Thangaraj.
Contex scanners are known for their versatility and producing the highest quality scans, and the HD fl atbed and 36” are no exception. It’s possible to handle any scanning task and document type fast to give customers exactly what they want – no matter how sensitive or specialized. The all-wheel-drive (AWD) design for fragile and old media – provides a perfectly straight scanning path with an optimal hold across the whole width of large documents preventing image distortion and damage to fragile originals.

“We are particularly impressed with the Contex scanner’s ability to handle folded documents,” says Saravanan Thangaraj. “It’s amazing how much time we save – and without the worry of damage to our documents.”
