How to resample image in Google Earth Engine?
For example, I want to resample Landsat image from 30m to 10m, but I cannot find corresponding functions in Google Earth Engine. Right now there are only ‘resample’ (cannot change the spatial resolution) and ‘reduce_resolution’ functions there.
How to use functional programming in Google Earth Engine?
Another common problem faced by new users who are used to procedural programming paradigm is the proper use of if/else conditional operators in Earth Engine. While, the API does provide a ee.Algorithms.If () algorithm, the use of it is strongly discouraged in favor of a more functional approach using map () and filters.
Is there an ee.algorithm for Earth Engine?
While, the API does provide a ee.Algorithms.If () algorithm, the use of it is strongly discouraged in favor of a more functional approach using map () and filters. Earth Engine uses deferred execution, which means that the evaluation of an expression is delayed until its realized value is actually required.
How to change CRS transform in Google Earth?
If you want even more control over the projection, you can manually change the CRS transform ( crsTransform) parameter: See the Projections doc page for more information. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
How to convert vector to raster in Earth Engine?
Vector to raster conversion in Earth Engine is handled by the featureCollection.reduceToImage () method. This method assigns pixels under each feature the value of the specified property. This example uses the counties data to create an image representing the land area of each county:
How to mask raster data in Google Earth?
For categorical (e.g. land cover) or QA data, choose a ‘Sample’ (the upper left pixel) or ‘Mode’ (most frequently occurring value, or sample if there is no mode) pyramiding policy. The masking mode indicates how the uploaded image is masked (if at all).
How to set scale in Google Earth Engine?
Like all image-outputting reducers in Earth Engine, the scale is dynamically set by the output. In this case, the scale corresponds to the zoom level in the Code Editor. Figure 1. The result of reduceToImage () using the ‘ALAND’ (land area) property of the ‘TIGER/2018/Counties’ FeatureCollection .
