Adding or removing layers can manipulate GIS maps. Layers can be hidden, the projection can be changed, the tie points can be changed, and the scale can be changed. A GIS map is built so it can adapt to a particular purpose.

A Global Positioning System (GPS) is able
tell the location of the car, then the OnStar unit in the car sends an
emergency message to the nearest center and sends them a message which tells
OnStar what happened. A member of OnStar then calls you’re the cellular phone
in your car, and if no one answers then OnStar will contact the nearest
emergency services.

GISis a system for displaying data related to positions on the Earth’s surface, Compare

the locations of different things, and maintain record.

According to Merriam-Webster the definition of false colours is “color in an image (as a photograph) of anobject that does not actually appear in the object but is used to enhance, contrast, or distinguish details.”

remote sensing is: The scanning of the earth by satellite or high-flying aircraft in order to obtain information about it

11b) Describe the process by which a false-colour image is produced.

The process by which a false-colour image is produced is by the producer using photo shop and altering the colour of the image being used to make it look different and less realistic.

image.

An advantage of using false colours rather than real colours in a satellite image is that it is much easier to detect fires with false-colour images.

The picture is showing us how Felix Tournachon work and the Bievere Valley, Paris France.1

1.  List 5 important ways that remote sensing information can be used in the study of the earth.

·  Remote sensing can be used to help study Earth’s surface and help to try and make changes on our earth that are caused by people. For example, the deforestation in South America caused by the destruction of the rainforests.

·   Also, the satellite can send back valuable information about global environments.

·  Helps people who work in farming, fishing, mining, and many other industries

·  Help study large tracts of land and how that land changes over time.

·  Provided color to our maps instead of having black and white.

1. In what season and at what time of day was the photograph on page 60 taken? Give evidence to support your answer. 

The season is not winter no snow no frozen lake the day time 

1. Why are some satellites in geostationary orbits while others are in north-south orbits?  What is the advantage of each?  Give examples of each type.

geostationary and near- polar orbit are allowed to see the coplidl world
