Free GIS for Engineering (MCQ) Questions and Answers

Question 1

Which kind of geodatabase allows for the presence of several editors—but only if they each work on a separate subset of the data?

Accepted Answer

File geodatabase

Answer

Multiple editors can operate on different areas of the data at the same time with a file geodatabase. This indicates that as long as they are working on separate database features or sections, multiple users can change the data in the file geodatabase. This makes it possible for people to update and alter the data together without running afoul of one another's edits or conflicts. Multiple editors may be permitted in enterprise, Microsoft, and personal geodatabases; however, they are not subject to the same limitation of working on distinct portions of the data.

Question 2

Which map data within the installation border includes utilities, physical features, and facilities?

Accepted Answer

Common installation picture (CIP)

Answer

Map data that contains physical elements, utilities, and facilities inside the installation perimeter makes up the Common Installation Picture (CIP). It offers a thorough perspective of the installation, facilitating efficient resource management and planning. For coordination and decision-making inside the installation, the CIP is an invaluable instrument.

Question 3

Which three vector data type groups are there?

Accepted Answer

Points, lines, and polygons

Answer

In vector data, there are three type groups: polygons, lines, and points. Points on a map denote distinct locations or features, like a single structure or a particular point. Roads, rivers, and boundaries are examples of linear features that are represented by lines. Areas or regions, such as land parcels, lakes, or nations, are represented by polygons. Despite being frequently linked to vector data, imagery is not one of the three type groupings.

Question 4

What is the term for the relationship between an image's size and the quantity of grids per unit?

Accepted Answer

Resolution

Answer

The ratio of an image's size to its number of grids per unit is called resolution. It is frequently expressed in terms of dots per inch (DPI) or pixels per meter and is used to characterize the sharpness and detail of an image.

Question 5

Which tables provide distinctive features for the data?

Accepted Answer

Attribute

Answer

The right response is "Attribute." An attribute in a database or spreadsheet refers to a particular feature or property of a data object. It offers distinct features for each input of data and is used to describe or classify the data. Tables with attribute data offer distinct qualities for every data set. Better organization and analysis of the data are made possible by attribute data tables, which offer comprehensive information on the numerous attributes or features connected to the data.
