Europe were able to find and get in touch as well as reach other places of the
world such as Asia. Now those maps that were prepared on chart paper were the
things of the past. Today, we are living in digital world were digital map serves the purpose of navigation. These digital
maps are also available to all the numerous citizens who are using it as GPS

created by architectures. Before the creation, they are destined to prepare the
outlay of the structure, previously, those outlays were prepared on simple
charts that needs to be perfect and it took lots & lots of time to figure
out each and every mistake, rectify it & do it again, but with the three
dimensional digital model the rectification can be done in minutes and the
particular architecture can show the final outlay to his/her bosses with even
the minute details available in the outlay that can eventually satisfies them
and they can approve the structure of the building.
