Surveyors use specialized tools and trigonometry to measure distances and make maps. You can take your own measurements with a measuring tape or other device and make a map based on those measurements. You can also generate a map using a global positioning system (GPS) device.
people who make maps are not called mapmakers for a very scientific name they are called cartographer
Your question is unclear. If i want to measure distance on a map I just use a ruler and compare it to the scale printed on most maps.

A pantograph.
there are many instruments used to measure length depending upon the size of object , Ruler is Metric instrument used to measure length. Screw gauge is also used as an instrument used to measure length in mm.
The barometer is the instrument that is used to measure the air pressure.
One instrument used to measure roughness of roads is the response type road roughness meters (RTRRMs)
The instrument which is used to measure snowfall is called a snow gauge.

The instrument used to measure the total distance that a car has traveled is called an odometer.
the answer is a ruler because it is and instrument used to measure someone in govern
This instrument is a balance.
The instrument you are looking for is a compass
polytechnic drawing instrument
A pantograph.
A pantograph is a device used for enlarging and reducing maps with accuracy. It consists of linked arms with adjustable pointers that can trace an image at one scale while replicating it at a different scale. By adjusting the settings of the pantograph, accurate changes in map size can be made.
