FREE Esri Technical Data Management Questions and Answers

Question 1

Which of the following are common practices for managing data in a geodatabase?

Accepted Answer

Creating domains for attribute validation.

Answer

Creating domains for attribute validation is a common practice in geodatabase management to ensure data quality and consistency. Domains define a list or range of valid values for an attribute field, preventing incorrect or inconsistent data entry. This helps maintain the integrity and reliability of the spatial data.

Question 2

Which geodatabase type is best suited for small-scale, single-user applications?

Accepted Answer

File geodatabase

Answer

A file geodatabase is a collection of GIS datasets stored in a file system folder, making it ideal for small-scale, single-user applications. It offers good performance, is easily transportable, and doesn't require a database management system, making it a convenient choice for individual projects or small teams.

Question 3

What is the primary purpose of versioning in an enterprise geodatabase?

Accepted Answer

Allowing multiple users to edit data simultaneously.

Answer

Versioning in an enterprise geodatabase is primarily designed to enable multiple users to edit the same data concurrently without interfering with each other's work. It creates isolated versions of the data for each editor, allowing them to make changes, resolve conflicts, and then merge their edits back into the default version. This facilitates collaborative editing in multi-user environments.

Question 4

Which tool would you use to validate the geometry of a feature class?

Accepted Answer

Check Geometry

Answer

The "Check Geometry" tool is specifically designed to identify and report geometric problems within a feature class, such as null geometries, short segments, self-intersections, or duplicate vertices. It helps users understand the nature of geometry errors before attempting to repair them. The "Repair Geometry" tool would then be used to fix these identified issues.

Question 5

Which data format is ideal for sharing spatial data non-GIS users?

Accepted Answer

GeoJSON (.geojson)

Answer

GeoJSON is a lightweight, open standard format for encoding geographic data structures, making it highly suitable for sharing spatial data with non-GIS users, especially in web applications. It is human-readable and easily parsed by many programming languages and web mapping libraries. While CSV with latitude and longitude can also be used, GeoJSON is specifically designed for spatial features.
