Is there possible way to extract coordinates within a polygon?
However, you could approach the problem by: 1. saving the polygon feature to a KML file; 2. parse the KML file using an XML reader in your favorite language; 3. construct a grid of coordinates that you want to test; 4. use a library (such as JTS in Java, GEOS in C, Shapely in Python) that implements a point-in-polygon algorithm.
How to export data from Google Earth Engine?
Export.table is for exporting tables, also known as FeatureCollection s. You have an image, not a table. The most efficient way to get the data out of Earth Engine is to use Export.image instead, then convert the downloaded GeoTIFF to suit your R program.
How to calculate the number of grids in a polygon?
Since there are 21 features (GCMs) for a single day, I am expecting the final data to have number rows equal to number of grids in polygon X 21 features (GCMs) Error: Invalid argument: ‘collection’ must be a FeatureCollection. How can I solve this?
How to extract data from Google Earth Engine?
The most efficient way to get the data out of Earth Engine is to use Export.image instead, then convert the downloaded GeoTIFF to suit your R program. However, since this dataset is very small, downloading it as a CSV will work fine, and the tool for that is ee.Image.sample which converts a region of an Image to a FeatureCollection.
How to extract raster values for points in Earth Engine?
If the points or polygons you want to extract raster statistics for are stored in a local shapefile or csv file, first upload the data to your Earth Engine assets . All columns in your vector file, such as the plot name, will be retained through this process.
When to use circles instead of squares in Google Earth Engine?
The radius is set to 45 m to correspond to the 90 m pixel resolution of the DEM. In this case, circles are used instead of squares (set the second argument as false i.e., do not use bounds). Two important things to note about the zonalStats function that this example addresses:
