Surveyors have been measuring distances, directions, and angles between points and elevations of points, lines, and contours on, above, and below the earth’s surface. Surveying and mapping technicians assist the professionals like cartographers and photogrammetrists in their duties by collecting data in the field and using it to calculate mapmaking information for use in performing computations and computer-aided drafting. Today there is much more to surveying and cartography than meets the eye. The surveying aids from old times – Chains, transits, theodolites, and plumb lines have given way to new age technology such as the GPS, laptops, and robotic total stations. GIS has also become an invaluable tool to both surveyors and cartographers.

As more of these new technologies emerge and are developed, we see a new type of mapping scientist emerging from the older specialists in photogrammetry and cartography. This new age mapping scientist combines the functions of mapping science and surveying into a broader field concerned with the collection and analysis of geographic data.

Growing opportunities in this realm have these new technologies as catalysts. Thus the growth of the surveying industry is being watched closely today! Studies are being done to understand the intricacies of development in this sphere and such studies create great value in bringing forth the correct perspective. A study done through questionnaire survey by the Asia Pacific group of GIS Development analysed the present status of land surveying in India and the results are encouraging.

Keeping in mind the need for more such studies, GIS Development will continue to make efforts to conduct and contribute more such studies to the surveying community in the future.
