What is Cloud Computing?

• “Internet-based computing that provides shared computer processing resources and data to computer and other devices on demand.” (Source: Wikipedia) Source: http://learningcloudcomputing.com

Who has used it?

We use it all the time

Benefits

Google Earth Engine

• A cloud-based geospatial processing platform for planetary-scale environmental data analysis. – petabyte of publicly available satellite imagery and

geospatial data – enables carrying out of complex image processing

tasks and spatial analyses without needing any GIS and remote sensing software.

Datasets

• Satellite Imagery– LandSat, Sentinel, MODIS, etc.

• GeoPhysical– DEMs, Land Cover, Cropland,

Surface Temperature, etc.• Climate and Weather

– WorldClim, TRMM, CHIRPS, etc.

• Demography– Gridded Population of World

(1km), WorldPop (100m)

Own data can be uploaded and used too

Computing Engine

• Offers highly efficient and powerful computing facility• Parallel computing on many CPUs across many computers in

Google’s data centers.• Results cached reducing re-computation of the same but

multiple requests

Application Programming Interface (API)

• Earth Engine functionality exposed through JavaScript and Python APIs.

• Supports complex geospatial analyses – map algebra, – image processing, classification, change detection, – time series analysis, – vector-based extraction of image statistics

• Results in the form of chart, map, table or image export.
