Which statement best describes the relationship between remote sensing and gis?

It provides data which we use a GIS (Geographic Information System) to analyse. Remotely sensed images are only one of many types of data that a GIS can work with. A GIS can analyse spreadsheet data, it can analyse vector data and many others. That said, remotely sensed data is an invaluable source of data in GIS.

What is the role of remote sensing in GIS?

Remote sensing is one of the methods commonly used for collecting physical data to be integrated into GIS. Remote sensors collect data from objects on the earth without any direct contact. They do this by detecting energy reflected from the earth, and are typically mounted on satellites or aircraft.

What is remote sensing and its types?

There exist two main types of remote sensing classified according to the source of signal they use to explore the object, active vs. passive. Active remote sensing instruments operate with their own source of emission or light, while passive ones rely on the reflected one.

What is GIS and its importance?

GIS stands for Geographic Information system. It is a computer system that collects, analyzes, stores and disseminates geographic information for use by different entities to facilitate informed and smooth decision making. GIS has important uses in different fields, including in the environmental field.

What are the applications of remote sensing in civil engineering?

Site Investigation: Remote sensing is used extensively in site investigations for dams, bridges, pipelines. It can be used to locate construction materials like sand and gravel for the new projects.

Why do geographers use GIS?

Geographers use GIS to find relationships and trends in geographic data. GIS allows them to present data visually as maps, reports, and charts. For example, a geographer can overlay aerial or satellite images with GIS data, such as population density in a given region, and create computerized maps.
