v1.0.24

• #94 Support transparent underlays
• Upgrade to .NET 7
• Package upgrade

v1.0.23

Happy New Year! This is a config release only, via #93:

• Fix GOES-18 longitude
• Add Himawari-9 support

Many thanks to @JVital2013 for these updates.

v1.0.22

• #85 Increased JPEG quality for output images and cached underlays (thanks @JVital2013!)
• Fix bad atmosphere maths, increasing quality of image around Earth's circumference

If you're extracting the new Sanchez release over the top of an existing release, delete your cache folder in order for higher quality underlays to be generated.

v1.0.21.1

This is a patch release to fix an oversight with the gaussian noise function introduced into the last build:

• Fix gaussian noise blending mode
• Make noise more subtle
• Enable noise by default

If subtle noise really isn't your bag, you can disable it with -n.

v1.0.21

• Performance improvements
• Rewritten haze / atmosphere generation, using a gradient file for hopefully more pleasing fake atmosphere
• Fix bug with gradient generation, allowing uneven gradient positions
• Add gaussian noise command-line option to create images which look marginally less computer generated
• #84 additional logging for image stitching and fix for rendering issue if multiple source images identified at same longitude
• Update of dependent libraries

v1.0.20

This release contains the following enhancements:

• #82 Add support for GOES-18

Sanchez has also been upgraded to .NET 6, so there should be some performance gains.

v1.0.19

This release contains the following enhancements:

• #76 Log source filename on image read failures
• #78 Update Satellites.JSON to reflect occasional usage of GOES 14 and 15
• #79 Update satellites.json to reflect change of naming convention for EWS-G1
• #80 Allow output format to be specified when doing bulk conversion

v1.0.18

This release contains the following enhancements:

• #70 Improved EWS-G1 default crop (thanks creinemann!)
• #72 Dynamically identified EWS-G1 horizontal offset for cropping
• Optional adaptive histogram equalisation via -A / --adaptivelevel

It also contains the following breaking changes:

• Brightness in Satellites.json now applied to stitched images only
• Default histogram equalisation mode changed from adaptive back to global

The change to Brightness was because it has no positive effect when performing histogram equalisation. Instead, it can lead to blown highlights for values over 1.0. Restricting it to image stitching means it can be adjusted to achieve seamless coverage while not adversely affecting non-stitched images.

I've added a page detailing the different histogram equalisation modes with examples.

v1.0.17

Fixed timestamp handling for Electro-L no. 2 files

This release fixes a bug where filename timestamps in Electro images were naively assumed to be UTC. Sanchez now parses Electro filename timestamps as Russian Standard Time, removing the need to manually rename files when creating multi-satellite stitched images.

v1.0.16

• Added 0.5km spatial resolution support (#64)
