I've got a dataset of ~60 points that we've taken during a series of oceanographic cruises where we were sampling, among other things, sea surface temperature. I'm interested in comparing these point samples to MODIS SST but I'm not sure exactly how to efficiently go about filtering MODIS by each point in my series in GEE. Is there a good way to find the closest MODIS image to my point sample date but not include it if it is outside of some date range?
I've got the basics but I'm not sure where to go from here:
var modis = ee.ImageCollection('NASA/OCEANDATA/MODIS-Aqua/L3SMI') var point_samples = ee.FeatureCollection('my collection of points') var modis_filtered = modis .filterDate('2018-08-01', '2018-8-15') // I want to filter by each point .median(); var modisSST = modis_filtered.select(['sst']);
