$filterDate not working on S1 and S2 data, works on landsat

[raruggie]

• rgee version: rgee_1.1.5
• R version: 4.1.3
• Operating System: Windows 10

At submit an issue, please attached the following information of your rgee session:

• [x] You have the Python API installed (from terminal):

  earthengine -h

  Yes, this does not work when I copy and paste into anaconda powershell prompt but I can confirm the API works since I can pull data from gee using rgee commands

• [x] You can find the credentials file on your system:

  library(rgee)
  ee_path <- path.expand("~/.config/earthengine/credentials")
  file.exists(ee_path)

  What is '~/.' part of the path??

• [x] You can run a simple EE command from R:

library(rgee)

# Initialize the Earth Engine module.
ee_Initialize()

# Print metadata for a DEM dataset.
print(ee$Image('USGS/SRTMGL1_003')$getInfo())

Yes, this gives a big output, the first few lines are:

$type
[1] "Image"

$bands
$bands[[1]]
$bands[[1]]$id
[1] "elevation"

$bands[[1]]$data_type
$bands[[1]]$data_type$type

Attach your Python (reticulate) configuration:

library(reticulate)
py_config()

Description

Describe what you were trying to get done. Tell us what happened, what went wrong, and what you expected to happen.

I am following an rgee tutorial: https://www.css.cornell.edu/faculty/dgr2/_static/files/R_html/ex_rgee.html

under 3 Example: Imagery, the code gives:

dataset <- ee$ImageCollection('LANDSAT/LC08/C01/T1_8DAY_EVI')$filterDate('2017-01-01', '2017-12-31')
ee_print(dataset)

Which works on my machine, i.e. the filter reduces the number of images to 46, number shown in the tutorial. However, I am working with Sentinel data, so I changed the above code to:

dataset <- ee$ImageCollection('COPERNICUS/S1_GRD')$filterDate('2017-01-01', '2017-12-31')
ee_print(dataset)

This runs on my machine, but when I look at the output, the Image collection was not filtered, it contains over 36000 images:

ImageCollection Metadata:
 - Class                      : ee$ImageCollection
 - Number of Images           : 360662
 - Number of Properties       : 2
 - Number of Pixels*          : 3.724005e+14
 - Approximate size*          : 2.09 PB

Something is going on with the mix of Sentinel data and $filterDate since the filter works on Landsat

I should also say that the same happens with S2:

dataset <- ee$ImageCollection('COPERNICUS/S2_SR')$filterDate('2017-01-01', '2017-12-31')
ee_print(dataset)

output:

ImageCollection Metadata:
 - Class                      : ee$ImageCollection
 - Number of Images           : 112336
 - Number of Properties       : 23
 - Number of Pixels*          : 8.657375e+12
 - Approximate size*          : 3.21 PB
