GIS Interview Questions

Q1.What is geographic information systems?

Geographic information systems, or GIS, is a data structure specifically designed to manage data visualization using geographic markers. For example, GIS specialists can use GIS technology to create a layered map of data points illustrating weather changes over time. Many different industries and companies use GIS technology and employ GIS specialists to manage their data, look for trends and create easy-to-understand visualizations.

GIS specialists often have education and training in environmental science and GIS technology. Most companies prefer a candidate with an associate’s or bachelor’s degree and some experience in the field. In addition to geographical understanding and related critical thinking, GIS specialists should have an understanding of design applications that allow them to create 3D renderings of their data.

When interviewing for a GIS specialist position, you can expect a series of standard questions related to your general background, education, experience and the specifics of the field.

Q2.What skills do you think are most valuable for a GIS specialist?

GIS specialists should have a variety of hard and soft skills to do their work well. The hiring manager might ask you which skills you deem most important to see what you value in your work and if those skills align with the company’s goals.

Q3. Explain the difference between geo-coding and geo-referencing.

This question requires specific GIS knowledge to answer. The hiring manager might ask this question or something similar to establish that you know the intricacies of the field.

Q4. While Using Arc Catalog, Do You Rely On The Default Templates Or Usually Go For A Customized One?

Well, it depends on the project really. Some of the default templates are really good and safe to use. I make the choice based on the project caliber.

Q5. Differentiate Between Gis Commands And Tools?

Commands do not require interaction with the map, they just rely on surface. Tools on the other hand require interaction with the map canvas.

Q6. What Is The Difference Between Geo-coding And Geo-referencing?

Geo-coding is when you associate a place name or an address with map coordinates. Geo-referencing is the process of associating plain digital images taken from a satellite or a plane with map coordinates so that they can be overlaid on street maps.

Q7. Which Applications Of The Arc Gis Desktop Are You Familiar With?

I am familiar with Arc Map, Arc catalog and Arc toolbox.

Q8. What Are The Top 5 Skills A Gis Technician Must Have?

Skills in spatial data handling, algorithms, data conversion, model building and database programming.

Q9. Name The Two Data Structures That Have The Capacity To Hold Spatial Data.

The two data structures that can hold spatial data include raster and vector.

Q10. Define Remote Sensing?

Remote sensing refers to detection and classification of objects on or in earth without physical contact, generally attained through aerial sensors.

Q11. Do You Know Which Software Does Dc Gis Use?

The District GIS software standards consist of the Environmental Systems Research Institute Inc. (ESRI) products and Google Inc. geospatial services and software. The ESRI standard includes the ArcGIS line of desktop and server software product lines. The Google standard includes the Google Earth Enterprise line of server side products and Google Maps for mash­up type applications. Other geospatial software packages and vendors can be accommodated if necessary to meet specific business requirements.

Q12. What Is The Basic Work Of A Gis Technician?

A GIS technician works closely with end users to identify GIS data requirements and handle technical issues. It is also the job of a GIS technician to manage data maintenance and manipulation and handle extraction activities along with ensuring preparation, planning and updating a variety of maps and drawings to be part of a GIS database.

Q13. What Are The Key Factors In Determining The Period For Record Retention?

Nature of data, government rules and policies regarding data retention and data privacy factors.

Q14. What Is A Geographic Information System?

GIS is a system of computer software, hardware, data, procedures and personnel combined to help, manipulate, analyze, and present information that is tied to a geographic location.

Q15. What Is Spatial Etl?

Spatial ETL tools provide the data processing functionality of traditional Extract, Transform, Load (ETL) software, but with a primary focus on the ability to manage spatial data. They provide GIS users with the ability to translate data between different standards and proprietary formats, whilst geometrically transforming the data en route.

Q16. What Is Hydrological Modeling?

GIS hydrological models can provide a spatial element that other hydrological models lack, with the analysis of variables such as slope, aspect and watershed or catchment area.

Q17. What Is Gis Data Mining?

GIS or spatial data mining is the application of data mining methods to spatial data. Data mining, which is the partially automated search for hidden patterns in large databases, offers great potential benefits for applied GIS­based decision making. Typical applications including environmental monitoring. A characteristic of such applications is that spatial correlation between data measurements require the use of specialized algorithms for more efficient data analysis.

Q18. What Is Geostatistics?

Geostatistics is a branch of statistics that deals with field data, spatial data with a continuous index. It provides methods to model spatial correlation, and predict values at arbitrary locations (interpolation).

Q19. What Is Gis Technologies?

Modern GIS technologies use digital information, for which various digitized data creation methods are used. The most common method of data creation is digitization, where a hard copy map or survey plan is transferred into a digital medium through the use of a CAD program, and geo­referencing capabilities.

Q20. Which Of The Following Are Examples Of Non­-cartographic Output?

  • Charts
  • Tables 
  • Dynamically linked graphs

Q21. What Does The Abbreviation Vrml Stand For?

Virtual Reality Modelling Language

Q22. Which Of The Following Are Important Characteristics Of A Sdss?

  • They are easy to use.
  • They incorporate spatially explicit models.
  • They are designed to make full use of available data.

Q23. What Is A Linked Display?

A set of graphs and maps where items are linked in separate displays.

Q24. What Is Chart Junk?

chart junk : Unnecessary detail around maps and diagrams

Q25. What Is Remote Sensing?

Remote sensing refers to detection and classification of objects on or in earth  without physical contact, generally attained through aerial sensors.

Q26. What Are Gis Commands?

Commands do not require interaction with the map, they just rely on surface.

Q27. Do You Know The Role Of Gps In Gis?

Competent decisions can only be rendered by reliable data and though GIS is an amazing data management tool, using it with GPS helps in validating the data analysis and results.

Q28. What Are Gis Tools?

GIS tools on the other hand require interaction with the map canvas.

Q29. What Is Geo­-referencing?

Geo­referencing is the process of associating plain digital images taken from a satellite or a plane with map coordinates so that they can be overlaid on street maps.

Q30. Discuss Briefly Data “information” As One Component Of Gis

There are two basic types of map information in a GIS: Spatial and Aspatial (DESCRIPITIVE-attribute)

  • Spatial refers to geographic features that are represented as raster (pixel) or vector (POINTS, LINES, and POLYGONS)
  •  Aspatial or Descriptive refers to TABULAR DATA which records characteristics of the geographic features

Q31. What Is The Difference Between Automated Cartography, Cad, And Gis

GIS – Adds the analytical capabilities (graphic+ attribute) while automated cartography and CAD lack (graphic only)

Q32. What Is Geo­-coding?

Geo­coding is when you associate a place name or an address with map coordinates.

Q33. What Is The Difference Between Gis And Lis

Land Information System (LIS) is typical to GIS, but related primarily to large scale and parcel-based system such as Automated Mapping and Facilities Management (AM/FM)
