Introduction to GIS

GIS is:

• A type of software for creating and managing maps

• A global information system

• A geological survey method

• A genetic information system

What are the unique capabilities of GIS?

• Data visualization and mapping

• Word processing

• Spreadsheet calculations

• Web browsing

What questions can GIS answer?

• Location-based questions

• Mathematical equations

• Historical events

• Literary analysis

The scale of GIS data is:

• 1:1,000

• 1:10,000

• 1:100,000

• 1:1,000,000

Vector data in GIS is:

• A type of data that represents geographic features with points, lines, and polygons.

• A type of data that represents geographic features with pixels.

• A type of data that represents geographic features with 3D models.

• A type of data that represents geographic features with sound waves.

Map features in GIS are:

• tools used for spatial analysis

• elements that represent real-world objects

• software for mapping

• data storage formats

Feature attributes in GIS are:

• the spatial characteristics of a feature

• the non-spatial information about a feature

• the geographic coordinates of a feature

• the visual representation of a feature

What is raster data in GIS?

• Raster data in GIS is a type of data that represents geographic information through a grid of cells or pixels.

• Raster data in GIS is a type of data that represents geographic information through vector lines and points.

• Raster data in GIS is a type of data that represents geographic information through textual descriptions.

• Raster data in GIS is a type of data that represents geographic information through 3D models.

Key figures in the early years of GIS were:

• Roger Tomlinson and Jack Dangermond

• Bill Gates and Steve Jobs

• Albert Einstein and Isaac Newton

• Marie Curie and Rosalind Franklin

What are current and future GIS technologies?

• Remote sensing and GPS

• Blockchain and AI

• Both A and B

• None of the above
