What is tileScale in Google Earth Engine?
Setting a higher tileScale reduces the size of those tiles. This means that: Less memory is used by each tile (so the computation is less likely to run out of memory). There are more tiles, which take more time to set up (so the computation will take longer).
What is Google Earth’s scale?
Map scale is a mathematical method for expressing how map distance compares to ground distance, the distance on the surface of the earth. Because a map’s scale determines how features are represented on the map, it also affects the overall interpretation of the map.
How does the scale work in Earth Engine?
A graphic representation of an image dataset in Earth Engine. Dashed lines represent the pyramiding policy for aggregating 2×2 blocks of 4 pixels. Earth Engine uses the scale specified by the output to determine the appropriate level of the image pyramid to use as input. Image assets in Earth Engine exist at multiple scales, in image pyramids .
How are image assets calculated in Earth Engine?
Image assets in Earth Engine exist at multiple scales, in image pyramids . The pyramiding policy (represented by dashed lines in Figure 1) determines how each pixel at a given level of the pyramid is computed from the aggregation of a 2×2 block of pixels at the next lower level.
How to create a time series in Earth Engine?
Tutorials contributed by the Earth Engine developer community are not part of the official Earth Engine product documentation. This tutorial provides methods for generating time series data in Earth Engine and visualizing it with the Altair library using drought and vegetation response as an example.
How is Google Earth Engine used in this tutorial?
Note that this tutorial uses the Earth Engine Python API in a Colab notebook. At the heart of this tutorial is the notion of data reduction and the need to transform data into insights to help inform our understanding of Earth processes and human’s role in them.
