Question

which device is used to create map chart etc on a paper sheet​

Answer 1

Explanation:

Most of the paper maps had been prepared on the basis of old conventional surveys. New maps can be produced using improved technologies but this requires time as it increases the volume of work.

The most important component inside a scanner is the scanner head which can move along the length of the scanner. The scanner head contains either a charged-couple device (CCD) sensor or a contact image (CIS) sensor. A CCD consists of a number of photosensitive cells or pixels packed together on a chip. The most advanced large format scanners use CCD’s with 8000 pixels per chip for providing a very good image quality.
