What are the leading problems for the invention of GIS and remote sensing?
Lack of coordination among the RS and GIS community. Lack of manpower and misplacement of expertise. Lack of geography schools and remote sensing centers. Remote sensing and GIS are too much business-driven.
What is projection in GIS?
A projection is the means by which you display the coordinate system and your data on a flat surface, such as a piece of paper or a digital screen. ArcGIS Pro reprojects data on the fly so any data you add to a map adopts the coordinate system definition of the first layer added. …
What are spatial problems?
The term “spatial problems” means not only difficulties in knowing right from left, but recognizing that “was” is not the same as “saw” or “b” the same as “d.” When teachers or those who test children use the term “spatial problems,” they mean not only the above, but also those children who crowd all of their …

How can GIS Help us understand public health issues?
In 2017, GIS played a role in a study about the Ebola virus ( B.L. Gleason et al. 2017 ). (And many other cases.) As evidenced by these situations, GIS has been successful in providing a deeper understanding of public health issues.
Should GIS data be regulated?
The more GIS is combined with emerging technologies, the more useful it becomes in solving real-world problems. These technologies include AI, Deep Learning, Machine Learning, Augmented reality, cloud computing, IoT, and real-time data collecting and analysis. However, there needs to be some regulation on the data that users should have access to.
