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

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.

The first aerial photograph was taken in 1858 by Felix Tournachon, from a tethered balloon over the Bievre Valley in France. Aerial photography is the taking of photographs of the ground from an elevated position. The camera is not supported by a ground-based structure,but sometimes it supported by a ground based.

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

11c)  Explain the advantage of using false colours rather than real colours in a satellite

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.

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.

Aerial photographs can be used in construction to see progress of a project and of site development

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

RADAR-SAT is a satellite launched by the Canadian Space Agency November 4,1995. The RADAR-SAT uses SAR technology which allows it to see in the dark,look beyond clouds and can even see through fog, this machine also operates day and night and operates regardless of weather condition. These images are useful to Fisheries and Oceans and such as they harsh fog and weather make directing the fishing vessels around the ice very hard but from a satellite it would be much easier to monitor the movement of the ice caps. As RADAR-SAT maps clear positions of the ice distributions, Canadian fishing vessels can travel safely. RADAR-SAT can also measure ocean winds and waves, this makes the Canadian Coast Guard very well prepared for oncoming waves and dangerous situations. The RADAR-SAT is very helpful in many other countries as well as to Canada, such as helping countries monitor food growth.

2014-10-03 - Capable of scanning the Earth at all times, day or night through any weather conditions, RADARSAT 2 has typically acquired more than 30,000 images a year since its launch in 2007. Its images are used by research centres, private industries, and Government departments and agencies across the country and around the world.

11a) What are false colours?

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

Explain
how the GPS works.

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.

A GIS map is created starting with a base map of an area then transparent layers each with specific data on them are stacked onto the base map and each other to create a dynamic map. GIS combines the features of a database program with the features of a drawing program. The database program contains geospatial data such as longitude and latitude.

GPS is the satellite navigation system that is used to compute the exact latitude and longitude position of any place on Earth. It's created by the United States government and it was created in the mid-1980s. 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 On Star then calls you’re the cellular phone in your car, and if no one answers then On Star will contact the nearest emergency services. 24 satellites are needed for a GPS unit to work. GPS determines locations as latitude and longitude positions and able to store waypoints and tell you the distance and direction of a waypoint from your current position. More complex group combines GPS capability with interactive map databases which shows your location to landmarks. A marine navigation gathers information about water depths with port locations and other marine navigation aids. The OnStar system is used on intercity trucks, which sends the truck’s location back to the office.

Geographic Information systems are integrated software packages for the input management, analysis, and display of spatial information. Used to manage geographic data.

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.
