How to create an image in Google Earth?
The following illustrates methods for creating images, getting band subsets, and manipulating bands: // Create a constant image. // Concatenate two images into one multi-band image. // Create a multi-band image from a list of constants. // Select and (optionally) rename bands. // Add bands to an image.
Why is feature collection not possible in Google Earth Engine?
No data was found in classifier training input. Why is this possible for images but not for feature collections on Google Earth Engine? Here is how I tried reducing it to an image, which also did not work so far:
Can you reload images from Google Earth Engine?
Note that if you want to reload a Cloud Optimized GeoTIFF that you export from Earth Engine to Cloud Storage, when you do the export, set cloudOptimized to true as described here . In addition to loading images by ID, you can also create images from constants, lists or other suitable Earth Engine objects.
How is a random forest classifier used in Google Earth?
This example uses a random forest ( Breiman 2001 ) classifier with 10 trees to downscale MODIS data to Landsat resolution. The sample () method generates two random samples from the MODIS data: one for training and one for validation. The training sample is used to train the classifier.
How to calculate region in Google Earth Engine?
// Load input imagery: Landsat 7 5-year composite. // Load an input region: Sierra Nevada. // Reduce the region. The region parameter is the Feature geometry. // The result is a Dictionary. Print it. To force the computation, it suffices to print the result, which the Code Editor will display as a Dictionary in the console.
What does Google Earth Engine do with imagery?
The Google Earth Engine team monitor and ingest the imagery data almost as fast as they are produced, thus removing the burden from the user of searching, downloading, pre-processing and georeferencing.
How to set scale in Google Earth Engine?
See this page for more information about how Earth Engine handles scale. There are two ways to set the scale: by specifying the scale parameter, or by specifying a CRS and CRS transform. (See the glossary for more information about CRS’s and CRS transforms). For example, the meanDictionary reduction (above) is equivalent to the following:
