What is geospatial data visualization?

• The process of displaying data that has a textual component in a visual format.

• The process of displaying data that has a numerical component in a visual format.

• The process of displaying data that has a geographic or spatial component in a visual format.

• The process of displaying data that has a temporal component in a visual format.

What is remote sensing in the context of GIS?

• Acquiring and interpreting data about the Earth's surface from a distance using sensors.

• Collecting data about the Earth's surface by physically visiting different locations.

• Using satellite imagery to analyze weather patterns.

• Using sensors to measure the distance between objects in GIS.

Name one application of GIS in urban planning.

• Site selection for new developments

What is the purpose of GIS in environmental management?

• The purpose of GIS in environmental management is to collect and store data related to the environment.

• The purpose of GIS in environmental management is to analyze and visualize spatial data related to the environment.

• The purpose of GIS in environmental management is to predict future environmental changes.

• The purpose of GIS in environmental management is to monitor and control environmental pollution.

What are the two main types of spatial data in GIS?

• point data and line data

• topographic data and aerial data

• tabular data and image data

• vector data and raster data

What is the difference between raster and vector data in GIS?

• Raster data is made up of pixels and represents continuous data, such as satellite imagery or elevation models. Vector data is made up of points, lines, and polygons and represents discrete data, such as roads or boundaries.

• Raster data is used for representing boundaries and roads, while vector data is used for satellite imagery and elevation models.

• Raster data represents discrete data, while vector data represents continuous data.

• Raster data is made up of lines and polygons, while vector data is made up of pixels.

What is the role of GPS in GIS?

• GPS is not used in GIS.

• GPS is used to analyze spatial data in GIS.

• GPS is used to create maps in GIS.

• GPS is used to collect accurate spatial data in GIS.

What are some common data sources used in GIS?

• topographic maps, weather data, social media data, traffic data, land use data

• population data, elevation data, soil data, land cover data, hydrological data

• geological data, climate data, vegetation data, transportation data, demographic data

• satellite imagery, aerial photography, GPS data, census data, remote sensing data
