A NASA MEaSUREs project to provide automated, low latency, global glacier flow and elevation change datasets
When saving corrected or cropped S1 granules to NetCDF file, `scale_factor` and `add_offset` attributes were lost when storing values as `short` datatype (the attributes belong to the `encoding` settings and...
Add new `sensor_uid1` & `sensor_uid2` data variables of Uint8 type to datacubes. Both variables should have description of unique values: `description: unique sensor id: 4 = Landsat 4, 5 =...
Using granules `img_pair_info` variable, add binary array for 'ascending/descending' to the corresponding layers of the datacubes. Call new variables: ``` ascending1 = [true/false] ascending2 = [true/false] ```
Various fixes as we started building v2 mosaics: * New way to merge multi-EPSG mosaics: take values that correspond to the maximum count0 overall * sensor_flag attribute, encoding changes: reverse...
Just a note that we should align chunks in space across granules. If chunks are not aligned it can make time-series processing more I/O intensive
* Modify composites code for the **sensor_flag**: * Reverse the meaning of 0 and 1: 0 - included, 1 - excluded. This will allow for more intuitive display of data...
**Finish granule processing:** - [x] Finish remaining L7 processing @jhkennedy - [x] Transfer granules to s3://its-live-data @mliukis **Fix S1 granules:** - [x] develop and validate S1 correction workflow @mliukis -...
When there is rock and glacier ice in the same search chip, rock will often dominate the correlation. This creates artificially slow motion on the edges of glaciers and makes...
Currently used naming convention for the datacubes http://its-live-data.s3.amazonaws.com/datacubes/v2/S50W070/ITS_LIVE_vel_EPSG32718_G0120_X450000_Y4450000.zarr should be changed to be consistent with corresponding composites: http://its-live-data.s3.amazonaws.com/datacubes/v2/S50W070/ITS_LIVE_**velocity**_EPSG32718_**120m**_X450000_Y4450000.zarr To change global attributes within each of the datacubes in place (thanks...
This is a follow up issue to address once all S1 granules have restored their original M11 and M12 values (see issue #18): fix M11 and M12 values in datacubes...
