Chapter 12 - Closing Case - Google's Earth Engine Flashcards
What is Google Earth? How does the program map the earth?
A platform that presents a three dimensional representation of Earth based on a 70 petabyte database that contains satellite imagery, aerial photography, Street View photography, and geographic information system (GIS) data.
Superimpose the data onto a three dimensional globe, enabling users to view cities and landscapes from various angles.
What percentage of the globe is covered by Google Earth? How many km is covered by google street view and what is google street view?
97%. 16 million kilometres of street view, which provides interactive panoramas from positions along many streets in the world.
What is an interesting detail that can be picked up by the google earth with respect to the ground?
Soil composition more than 30 cm underground, and the amount of water vapour rising from the farmland.
What is the google earth engine (GEE)?
An application of the google earth. A cloud computing platform that enables users to analyze google earths database by providing a data catalogue of images, computational power, and data analysis software necessary to analyze the data.
How do scientists use the GEE? What is an example the GEE used to monitor? How many times does the Landsat Satellite/Sentinel 2 pass over one specific place in a day
To collaborate with each other by using the data, algorithms and visualizations created by the GEE. Monitor farming, natural resource use, and climate by using the geospatial data from the Landsat and Sentinel 2 satellite programs to detect any changes.
Landsat - 16 times a day.
Sentinel 2 - 10 times a day.
What is the role of the GEE in the Public and ProBono use?
Scientists can analyze massive data sets to answer critical questions for a number of pro bono clients that include conservation groups, city agencies, community advocated, and researchers. In addition, it is to support the public.
How is the GEE used to help people in the Ferlo Region of Senegal?
Climate change is making harder for herders to find water for their cattle. Thus the GEE scientists alert the farmers via radio to the best place to locate water.
How is the GEE used in Los Angeles?
Target locations in Los Angeles where planting trees would be most helpful in lowering surface temperatures.
How is the GEE being used by the government of Canada? What is the Natural resources Canada?
Map the status and trend of vegetation in the country. The natural resource Canada, the department that is responsible for the natural resources, energy, minerals, metals, forests, earth sciences, and remote sensing, has been used to track environmental changes.
What does the Natural Resources Canada generate every month? How does this map help out the greater good?
Maps of the vegetation parameters such as a canopy, which is the portion of a plant crop visible above the ground. It helps in assessing the environment and contributes to the data sets used to limit weather uncertainty.
What is the LEAF tool box? How does the Agriculture Canada want to use this tool?
Generated by some NRC researchers in January 2022, that generates customizable maps of foliage density in real time by building on GEE data. Assess the condition and progress of crops as it affects local economies the global food supply.
What is the collect earth? What can it detect.
A free, open source system created by the Food and Agriculture Organization (FOA) of the United Nations. It is used to view and interpret the high resolution satellite imagery. Detect deforestation, forest degradation, and other Changs in the landscape.
How is GEE used to help in Hawaii as they face a climate crisis? What do the different colours on the map imply?
A public mapping tool assisting policy makers and the public to decide where to invest resources as the state seeks to combat climate change. It allows policy makers, residents, and public officials to map and find the risk. Green low danger, yellow moderate, and red high
How was the GEE used to support the Map of Life biodiversity team>
Developed an interactive map to view and analyze habitat ranges and assess security of individual species. Allows them to refine predictions about where species at risk are likely to be. Parameters can be adjusted causing the map to change showing how risks will evolve.
How did the researchers at the University of Maryland use the GEE?
Survey the extent, loss, and gain of a global tree cover over the course of more than a decade. Analyzing all the land on the planet except Antarctica and the Arctic. They were able to create a map of global forest changes, noting it would have taken them 15 years but GEE has allowed them to do it in 15 days.
