25 GIS Technician Interview Questions and Answers

A Geographic Information Systems (GIS) Technician is responsible for compiling, analyzing, and displaying geographical data. They use this data to help organizations make better decisions about where to build things, how to plan for emergencies, and how to study the effects of climate change.

If you’re looking for a job in this field, you’ll likely need to go through a job interview. To help you prepare, we’ve gathered some common GIS Technician interview questions and answers.

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

This question is a great way for the interviewer to assess your knowledge of GIS and how you apply it in your work. Your answer should include an explanation of each coordinate system, including its purpose and when you would use it.

Example: “Yes, I am familiar with the different types of coordinate systems used in GIS. I have experience working with both geographic and projected coordinate systems. Geographic coordinate systems are based on a spheroid or ellipsoid model of the earth and use latitude and longitude to define locations. Projected coordinate systems are used to represent the curved surface of the earth on a flat plane by converting three-dimensional coordinates into two-dimensional coordinates. In addition, I am also knowledgeable about the various datums used for each type of coordinate system. Datums provide the reference points from which all measurements are taken, so it is important to understand how they work when using GIS software.”

2. What are some of the most important factors to consider when choosing a GIS software program for an organization?

This question can help the interviewer determine your knowledge of GIS software and how you apply it to a professional setting. Use examples from your previous experience to highlight your critical thinking skills, ability to collaborate with others and overall understanding of GIS technology.

Example: “When choosing a GIS software program for an organization, there are several important factors to consider. First and foremost is the cost of the software. It’s essential to make sure that the price tag fits within the budget of the organization.

The next factor to consider is the functionality of the software. Does it have all the features needed to complete the tasks required by the organization? Is the user interface easy to navigate and understand? Are there any additional add-ons or plugins available to enhance the capabilities of the program?

Another important factor is compatibility with other programs. Can the GIS software integrate with existing systems in place at the organization? This will ensure that data can be shared between different departments and applications. Finally, customer support should also be taken into account. Is there a reliable technical team available to help if issues arise?”

3. How would you troubleshoot a GIS database that is not working properly?

This question is an opportunity to show your problem-solving skills and ability to troubleshoot. Your answer should include a step-by-step process for how you would troubleshoot the database.

Example: “When troubleshooting a GIS database that is not working properly, I would first identify the issue. Is it an issue with data integrity or accuracy? Or is there a problem with the software itself? Once I have identified the issue, I can then start to look for potential solutions.

For example, if the issue is related to data integrity or accuracy, I would check to see if any of the data has been corrupted or lost. If so, I would attempt to restore the original data from backups. I could also review the data entry process and make sure that all steps are being followed correctly.

If the issue is related to the software, I would check to see if the software is up-to-date and running the latest version.
