First of all, it’s important to remember that there’s a difference between a job interview, a test interview, and a “professional” interview. But don’t worry, we’ve put together a list of the most common EADP 19-001: ArcGIS Desktop Professional interview questions for you. Let’s get started!

1. What are the three types of geodatabases?

• File geodatabases that are stored as folders in a file system
• Personal geodatabases where all the datasets are stored within a Microsoft Access data file (limited in size to up to 2 GB)
• Enterprise geodatabases which are also known as multiuser geodatabases are unlimited in size and number of users

2. Could you name the three main components of a geodatabase?

• Feature classes.
• Raster datasets.
• Tables.

3. What types of data can be stored in a geodatabase?

The geodatabase supports several types of GIS data used by ArcGIS, such as:

• attribute data
• geographic features
• satellite and aerial images (raster data)
• CAD data
• surface modeling or 3D data
• utility and transportation network systems
• GPS coordinates
• survey measurements

4. How would you create a file geodatabase?

• First, you need to open the Create File Geodatabase tool in the ArcGIS Pro
• Second, you need to specify the folder location wherever you want the file geodatabase should be created.
• Then, type the name for the geodatabase
• Further, choose the ArcGIS version that you want the file geodatabase to be
• Click Run

5.  Could you name the types of file formats used for the raster model?

• “GIS” Formats
• World Files
• ASCII Format (.asc)
• IMG
• TIFF
• JPEG
• Test Your Knowledge.

6. What are the three types of raster data?

• Raster datasets
• Raster catalogs
• Raster as attributes

7. What is considered a complex data set?

A complex data type is usually the result of data aggregation. For example, you could create a complex type that contains other simple types, such as built-in types and opaque types.

8. What are the properties of data sets?

• Centre of data.
• The skewness of data.
• Spread among the data members.
• Presence of outliers.
• Correlation among the data.
• Type of probability distribution that the data follows.

9. Could you elaborate on why is data interoperability important?

• Data Unity: Interoperability helps businesses bring their data together, which is important in managing and obtaining information from external systems and vice versa.
• Improved Data Protection: There is no business that can operate without proper data protection. Thanks to the process, sensitive information is protected.

10. What is the difference between interoperability and interface?

The difference between interface and interoperability is that the former is the point at which two entities are connected, and the latter describes a product or system’s ability to interact with its counterparts.

11. How would you define the ArcGIS coordinate systems data?

The ArcGIS Coordinate Systems dataset contains data files required for using the Geocon transformation method and vertical transformation files for the United States (Vertcon) and the world (EGM2008).

12. Could you differentiate between GIS and Geospatial?

GIS is an acronym for Geographic Information System; it refers to a computer system for collecting, storing, analyzing, and using geographic data. The term geospatial is often used when talking about the use of mapping and spatial analysis.

13. What is meant by data automation in GIS?

GIS transformations, such as spatial join, are often applied to large-scale GIS maps. Automating this process means you can run the transformation on one map instead of many maps. Automating processes involving GIS (geographic information systems) maps can streamline the work of manipulating large GIS maps, as large GIS maps are often divided into discrete tiles.

14. Could you explain what is meant by a hosted feature layer?

Hosted feature layers are vector layers hosted in ArcGIS Online or ArcGIS Enterprise that support querying, editing, and visualization. They can be added to web maps as visualizations and to mobile maps as tiled layers. In web maps, hosted feature layers are drawn by the browser and support interactive highlighting. 

15. What is the difference between a feature service and a feature layer?

A Hosted Feature Layer is stored within your site’s Managed Database, which means ArcGIS Server does not directly run or store the service. This contrasts with feature services, which are stored within ArcGIS Server.

16. Can you tell me what can you do with ArcPy?

• Geographic data analysis
• Data conversion
• Data management
• Map automation with Python

17. How would you define ArcPy mapping?

 Arcpy mapping is a Python scripting module that’s part of the ArcPy site package. It gets installed with ArcGIS Desktop, so it’s available to all licenses. As its name suggests, it was designed primarily to manipulate the contents of existing map documents (.mxd) and layer files.

18. What is meant by the term Arcpy modules?

 A module is a Python file that generally includes functions and classes, as well as references to other modules. ArcPy is supported by several modules, including: 

• data access module (arcpy. da)
• mapping module (arcpy. mapping)
• ArcGIS Spatial Analyst extension module (arcpy. sa)
• ArcGIS Network Analyst extension module (arcpy. na)

19. What is the importance of an Arcpy class?

ArcPy includes a number of classes that can be used to support Python-based workflows. Some additional classes can be found in other ArcPy modules, such as the charts module and the Data Access module, which are discussed later in this topic.

20. How would you describe a scratch geodatabase?

The GDB environment setting is the location of a file geodatabase you can use to write temporary data. If you choose to write output to the scratch geodatabase, your code will be portable because this geodatabase will always be available or created at execution time.

21. What can you do with Python in ArcGIS?

For learning GIS programming, Python is a good choice because it can be used both as a scripting and coding language. Other uses include automating tasks (through running Python scripts), along with writing applications, such as add-ins.

22. Could you elaborate on the importance of Python for GIS?

Python has become the dominant language for geospatial analysis because it is used by major GIS platforms, but increasingly users also see its potential for data analysis. Its relatively easy-to-understand syntax has helped increase Python’s popularity.

23. What is meant by the term ModelBuilder in GIS?

ModelBuilder provides a visual way to map out geoprocessing workflows. ArcGIS Pro comes with ModelBuilder, which has been called a visual programming language. You can think of ModelBuilder as a tool for creating maps that automate GIS workflows. A model is nothing but just a workflow map.

24. Can you highlight the purpose of ModelBuilder?

The ModelBuilder node provides an easy way to create three-dimensional models from standard two-dimensional footage. You can create a model by building shapes and then editing them and aligning models over your footage by dragging vertices to their corresponding location in 2D space.

25. How would you validate a GIS model?

To validate your model, simply click ModelBuilder > Run > Validate. This is ideally only a necessity after you have created a model and the data or tools in the model have been modified, moved, renamed, or deleted.

26. What is the first step in the model planning process, and what is the reason for that step? 

You need to determine your scenario and goal as they will determine the data you’ll use.

27. What is a Model Parameter? 

 A model parameter is nothing but simply a configuration variable that is internal to the model and whose value can be estimated from data. Such parameters define the skill of the model on your problem, and they are estimated or learned from data.

28. How would you customize ArcGIS Pro?

 Open ArcGIS Pro. In the ribbon, click the Project tab. Then, on the ArcGIS Pro start page, you need to click Settings in the lower-left corner. In the list on the left, click Options. Finally on the Options dialog box menu, under the option named Application, click Customize the Ribbon.

29. What are the tasks in ArcGIS Pro?

A task is a defined set of steps used to complete a business process or workflow. Tasks can be used to help you and others perform your work more efficiently, maintain consistent practices, or create a series of interactive tutorial steps.

30. Could you tell me what type of analysis can be done with GIS?

Six types of spatial analysis are:

• Queries and reasoning
• Measurements
• Transformations
• Descriptive summaries
• Optimization
• Hypothesis testing
