s1etad v0.5.0 (16/07/2021)
Merger functions now return masked arrays.
The
s1etad.product.Sentinel1EtadBurst
class now has two new properties:s1etad.product.Sentinel1EtadBurst.vg
, the average zero-Doppler ground velocitys1etad.product.Sentinel1EtadBurst.reference_polarization
, a string identifying the reference polarization
and a new method:
s1etad.product.Sentinel1EtadBurst.get_polarimetric_channel_offset()
to get the constant time offset of a polarimetric channel w.r.t. the reference one
Support for ETAD-DLR-PS-0014 “ETAD Product Format Specification” Issue 1.5 (SETAP v1.6):
new method (
s1etad.product.Sentinel1EtadBurst.get_timing_calibration_constants()
) for retrieving timing calibration constants
new
s1etad.ql
module for geo-coded quick-look images generation
s1etad v0.4.0 (01/12/2020)
Implement ETAD-DLR-PS-0014 “Product Format Specification” v1.2.
The burst catalogue initialization and the
s1etad.product.Sentinel1Etad.s1_product_list()
method have been re-implemented to exploit NetCDF instead of XML (30% faster product loading).All notebooks have been update to use the new demo products (with updated format).
The back-geocoding implementation has been simplified and improved (caching of ECEF coordinates during guess computation).
Fixed
s1etad.product.Sentinel1Etad.iter_bursts()
in case of emptyselection
.Fixed KMZ generation in case of missing slices.
Added min/max range time attributes to
s1etad.product.Sentinel1Etad
class.New notebook providing a basic step by step guide to perform the correction of a single Sentinel-1 SLC burst with the timings provided by the S1-ETAD products.
Now the
s1etad.product.Sentinel1Etad.s1_product_list()
always returns a list. Previously a string was returned in case of single swath.Fixed the
s1etad.product.Sentinel1Etad.query()
method in the case in which theproduct_name
parameter is used to search for S1 Standard (“S”) products.Always use the Sphinx RTD Theme (also for local builds).
s1etad v0.3.0 (27/10/2020)
Now
s1etad
is a package.Improved
get_footprint
methods:support for extended selection semantics (also accept the result of a query as parameter)
support for the
merge
option: now it is possible to request a single “merged” footprint; by default the method returns the set of footprints of all bursts
New
s1etad.product.Sentinel1Etad.get_statistics()
method.Added missing attributes to
s1etad.product.Sentinel1Etad
,s1etad.product.Sentinel1EtadSwath
ands1etad.product.Sentinel1EtadBurst
classes.Removed
s1etad.product.Sentinel1Etad.xpath_to_list()
method from the public API (the private one is still available)Strongly improved KMZ export function.
new dedicated
s1etad.kmz
module (providing thes1etad.kmz.s1etad_to_kmz()
function)removed the obsolete
s1etad.product.Sentinel1Etad.to_kml()
method
New methods to find points (and geometries) intersecting the burst/swath/product footprint.
New method and functions for direct and inverse geo-coding (approximated algorithm)
New Command Line Interface (CLI) for basic functions (only “export-kmz” at the moment).
Documentation:
added instructions to install via conda packages
added pointers to “stable” and “development” (latest) version of the documentation
s1etad v0.2.0 (12/09/2020)
Improved packaging and docs.
s1etad v0.1.0 (11/09/2020)
Initial release.
