A pantograph.
polytechnic drawing instrument
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.
there are different kinds of maps such as physical maps and political maps
theamatic maps are maps made to serve a particular purpose theamatic maps include maps showing agricultural activities in an area, maps showing population within an area, those showing forest cover in area generally this maps focus on a particular aspect
the different type of maps is the poo map, political map, physical maps biogeographic map envronmental maps etc .
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.
Definition of Pantograph1.An instrument for copying plans, maps, and other drawings, on the same, or on a reduced or an enlarged, scale. Alternative forms: Skew pantograph, a kind of pantograph for drawing a copy which is inclined with respect to the original figure. HarikrishnanSAKTHI PUBLISHING HOUSE
Sonar, RADAR and satellites and space travel improved the accuracy of maps after World War 2.
The accuracy. Of course compasses helped , but maps showed sailors or other explorers help accuracy on thir travels.

Topographic maps are easily recognized by their contour lines, which represent changes in elevation. These lines indicate the shape and steepness of the terrain, making it easier to visualize the physical features of the land. Additionally, topographic maps often include symbols and colors to represent natural and man-made features such as rivers, roads, and buildings.
Technology can make better maps by, increasing there accuracy of proportional value of length and width.

Aerial photography,satellites and gps have increased the accuracy of maps enormously.
Satelites. Aeroplanes. (those are the two major ones)
Katherine Fitzpatrick-Lins has written: 'The accuracy of selected land use and land cover maps at scales of 1:250,000 and 1:100,000' -- subject(s): Land use, Maps
Using the Google Maps service in the United Kingdom, one can see a basic map of the UK which can be zoomed in and out. Satellite images, Terrain, Weather, Traffic and photos can also be utilized for accuracy in the map view.
