Why Cartography still matters

September 19, 2021

What is cartography?

Maps have been the cornerstone upon which the world was discovered. Since ancient times, explorers have always relied on maps to discover and rediscover the world. Cartography is the art and science of designing, creating and reading maps. It takes a geographical area or location and puts it onto a 2 or 3 dimensional space.

It comes as no surprise that the central theme of cartography is location. Location of things and location of things in relation to other things. Other than location there are several other factors and considerations when it comes to cartography, such as the scale, coverage and source. We will talk a bit more about sources in the next section.

Evolution of Cartography

Map making has come a long way. The journey from a simple treasure to highly detailed live maps has been quite eventful. To understand the evolution of cartography, one must simply ask one question. What are maps used for? Or rather what were maps used for earlier and what are they used for now?

Back in the day, maps were used primarily for navigational purposes, to reach from point A to point B. But in recent times new technologies have surfaced, we started realizing that there is a lot more to maps than just navigation. Mapping has been deployed for powerful applications such as disaster management, environment monitoring and location-centric marketing.

Digital Cartography

Cartographers need to keep their end users in mind. The customer evolves and the product evolves along with it. Maps are hardly viewed on physical papers like they used to in olden times, but rather digitally in handheld and computer devices.

While the fundamental principles of cartography have stood the test of time, the sources, approach and technology have definitely changed. Digital cartography has a lot to do with data capture, manipulation and image processing. 

Instead of manual field surveys, cartographers rely on high resolution aerial imagery, GPS, sensors and satellites. These new sources have allowed the creation of highly detailed digital maps.

A combination of Remote Sensing technology and Geographical Information Systems (GIS) is leading to the creation of real time maps that can be put to use in a plethora of fields.

Applications

The integration is such that you are probably benefiting from digital cartography on a daily basis. We’d be surprised if you haven’t at least once in the last 24 hours!

Google maps are one of the most common examples that come to mind. Many of the food delivery apps, cab ordering apps that you use go beyond the basic navigational use of maps. There is almost a 2 way interaction with these live maps. 

Digital maps are extremely useful in disaster management as well. Many of the first rescue squads rely on digital maps to identify areas with maximum casualties to provide life support.

These products are also useful to environmentalists that are trying to preserve the environment. A bird’s eye view of the situation always helps.

Conclusion

With all the evolution that has taken place already, cartography still continues to make new strides every day. Maps keep getting more clearer and information keeps getting more real time. The most isolated of places on Earth are under everyone’s radar thanks to modern cartography. And yet, this is not the end, this is just the beginning.
