25 GIS Analyst Interview Questions and Answers

GIS analysts are in high demand due to the increasing popularity of Geographic Information Systems (GIS) technology. A GIS analyst is responsible for creating and managing maps and data. They use spatial analysis to understand relationships between people, places, and things.

If you want to work as a GIS analyst, you’ll need to be able to answer some common interview questions. In this guide, you’ll find questions and answers that will help you prepare for your interview.

1. Are you familiar with the different types of coordinate systems used in GIS?

This question is a great way to test your knowledge of GIS and how it uses coordinate systems. You can answer this question by naming the different types of coordinate systems used in GIS, their advantages and disadvantages and when you would use each type.

Example: “Yes, I am very familiar with the different types of coordinate systems used in GIS. I have worked extensively with both geographic and projected coordinate systems. Geographic coordinate systems are based on a spheroid or ellipsoid model of the earth’s surface and use latitude and longitude to define positions on the earth’s surface. Projected coordinate systems are based on a flat map projection that is used to transform locations from one coordinate system to another. I have experience using both of these types of coordinate systems for various mapping projects. In addition, I am also well versed in the concept of datums which are used to accurately measure distances between two points on the earth’s surface.”

2. What are some of the most important skills for a successful GIS analyst?

This question can help the interviewer determine if you have the skills necessary to succeed in this role. When answering, it can be helpful to mention a few of your strongest skills and how they relate to GIS analysis.
