County boundaries are needed on the map. This should be a selectable option. Layer ordering of boundaries vs. radar image seems appropriate, but coastlines are not visible underneath a radar image.

Qt Plugins are not deployed with the Linux package. As a result, the application fails to run without these already installed and locatable in the current environment.

This should be resolved using the existing deploy mechanism going to Qt 6.5, but needs to be verified.

Cleanup duplicative resource usage between map instances that use a shared OpenGL context. Consider caching certain resources to avoid having to reload when certain settings change.

The Linux build should set the rpath or runpath of the executable in order to eliminate the need to set LD_LIBRARY_PATH when running.

Automated builds need setup for Windows and Linux

Because futures are not tracked, if the application exits while an asynchronous operation is still running, undefined behavior can occur within those operations.

A mechanism needs to be created to track these futures and wait for asynchronous tasks to complete.

Level 2 products appear to rock back and forth as the frames animate.

Currently, the level 2 rendering takes the start angle, and assumes 0.5 degree or 1 degree radials. However, the angle can vary between radials and scans, so this must be calculated every frame.

The solution will likely be similar to that in 9c44257, but I expect all frames must be recalculated, instead of non-standard ones.

There is extensive use of the parallel STL using C++17 execution policies. The use of these algorithms behave as expected when compiling for Windows using MSVC.

When compiled for Linux using GCC, the parallel STL defaults to a serial backend, causing poor performance of parallel algorithms.

The Linux build should be updated to use a parallel backend, such as TBB, or another suitable parallel processing mechanism.

Notify the user when a new release is available. Allow disabling via a setting.

This epic is intended to capture overall progress on support for level 3 products.

As more options become available on the side panel, collapsible groups should be implemented

• Radar and animation toolboxes should be combined
• Save which groups are collapsed/expanded to settings

Add mPING support

The color table displayed on the map should have a legend. Consider flipping from horizontal to vertical with an inset. This is likely to uncover scaling issues with various products.

When double clicking an alert in the alert table, it should either "Go" or "View" the alert (default "Go", configurable in settings).

If the Windows display scale is set to anything other than 100%, UI elements do not display at the correct position.

I've experienced a rare (usually no more frequent than once per 24 hours of runtime) crash to desktop with handling of alert updates.

When line 415 above is executed, the application may crash if the message list for a key is empty. There should be two fixes:

1. Handle the case if the message list is empty, and return a default value. This will prevent the crash, but still may result in erroneous behavior.
2. Determine why message list is empty. This should never happen for a non-default/valid key.

The application needs a user's guide. This should be done using Read the Docs or a similar method.

When the radar product ComputeSweep() function takes a long time (~0.5 seconds or more), animation at higher speeds fails to render updated scans. This is seen on Linux when animating level 2 products, due to #54.

This is likely due to a race condition involving computing the sweep. It could be due to requesting another product too quickly, or another reason.

If the product renders quickly enough, or the animation is slow enough (loop speed), the issue is not seen.

Auto-refresh will intermittently fail at the start of a new UTC day, and disable refresh due to "no products available". The product must be selected again in order to re-enable refresh.

The AWS Level 2 Prune Test has an intermittent failure, causing issues with CI.

Linux support will come in a future update. Currently certain C++20 chrono features (timezones and formatting) are used, which only MSVC currently supports. GCC 16 is expected to bring additional support, otherwise portions will need rewritten, perhaps using Howard Hinnant's date library and/or fmt. Clang does not currently advertise support of these features.

When a level 3 file is loaded with a radial count other than 360 or 720, the product will not display.

When navigating to an alert, the selected radar site should be updated to the nearest radar (consider WSR-88D vs. TDWR).

Zone and county files will update effective September 19, 2023. Final versions are expected to be posted by July 18. The new files need integrated.

Add selection for level 2 reflectivity declutter

Not sure if you could get access to it but having a option to show/hide convective outlooks like the ones shown over at https://www.spc.noaa.gov/products/outlook/

Add support for NWS Local Storm Reports as described at https://www.spc.noaa.gov/climo/online/

A storm report should display on the map. When hovered over, additional information about the storm report should be displayed.

Storm reports should also be available in table format, similar to warnings. Maybe group them under alerts, using a separate tab?

Zone and county files will update effective March 8, 2023. The new files need integrated.

When moving the mouse cursor over the map, information about the hovered location should be displayed, including latitude/longitude and radar bin data.

The alert dock does not always refresh, and warning display has a tendency to become stale.

If a color table contains lower case statements, the color table does not load. The current logic assumes statements will be case sensitive as defined in the Color Table File Specification:

http://www.grlevelx.com/manuals/color_tables/files_color_table.htm

Add support for OS-provided location, or external GPS devices (e.g., Bluetooth, etc.).

Currently only Mapbox is supported as a tile source. Add support for MapTiler. Consider making this flexible for custom map sources as well, as supported by the MapLibre library.

Support for additional NEXRAD providers is needed, including:

• ONDAS (AllisonHouse)
• THREDDS
• NWS HTTP Archive
• Iowa State Mesonet (https://mesonet-nexrad.agron.iastate.edu/level2/raw/)

Display open source licenses and other credits in the About dialog (sub-dialog) acknowledgements markdown

As a user, I should be able to view all of the radar sites as labels on the map. Double clicking a radar's label should switch my current radar site to the site that was clicked.

Populate Version Information in the About dialog from Git, and a manual version tag

If events are updated out of sequence, the most recently received update will incorrectly be treated as the newest. This is not expected to happen during normal retrieval of text products, but can easily occur when loading products manually.

Currently, radar products are not garbage collected. Old products should be purged from memory.

The most recently used map style should be saved in the settings, similar to the last product selected.

When an alert/warning is hovered over on the map, a status window should be displayed giving additional information about the alert. There should be a clickable action to pull up the full alert information, similar to the tabular view.

A short option should be available to display only Impact-Based Warning Tags, as opposed to the entire text message segment.

Add a timeline to the application. This feature should allow the display of animated radar data in a specific time window, in addition to historical data. All products should be synchronized on the timeline as available.

Completed for Prerelease 1:

• Archive time selection
• Step through volume scans
• Animated radar image
• Adjust number of stored products based on loop time
• Add limits to loop speed
• Adjust time listing pruning from oldest first to oldest used first, omitting pruning yesterday and today
• Fix warning start time of Unix epoch when missing initial text product
• Auto refresh shouldn't replace stepped or archive display
• Fix level 2 display

Completed for Prerelease 3:

• Make delay between loop cycles configurable
• Older archive views don't work properly
  • Partially fixed. Tested OK with 2013 Level 2 data. Will require additional changes for ~2008 and prior (support for Level 2 Message Type 1)

Required for completion:

• Save loop time, speed, and delay in settings
• Fix step begin/end when not all products have the same volume times
• When playing a live view, auto update incorrectly states "Disabled"
• Fix switching radar sites in archive view, currently have to toggle live/archive again
• Fix crash when switching radar sites while loading data from the old site (easily reproducible when starting animation) (#51)
• Tweak UI to uncrowd the left panel
• Reduce product cache limit to only include volume times for that product

Maybe (could be deferred to future update):

• #59
• Stepped selection when live or archived should apply when changing radar sites
• Add configurable limit to loop time to prevent memory exhaustion
• Update animation logic to display intermediate level 2 volume scans

It would be nice to be able to pass a flag on my shortcut to disable the console window for those of us uninterested in seeing it.

Would like to see lightning strike data as option to show.

Add a tone for severe weather alerts.

• Alert tones should be off by default
• Alert tones should be configurable by alert type
• Alert tones should be configurable by location
  • Any location
  • Manually selected latitude/longitude or point on map
  • GPS location (Requires #13)
  • County
• Alert tones should be customizable
• Alert tones may use the EAS two tone alert by default:
  • https://commons.wikimedia.org/wiki/File:Emergency_broadcast_system.ogg
  • Default should be embedded as a Qt resource

A new library will be required to play audio, with multiple formats preferred (e.g., ogg, mp3, wav, etc.). Qt Multimedia should be given consideration along with lighter weight options. Note GPL dependencies must be avoided.

To monitor for updated alerts, a connection to TextEventManager::AlertUpdated can be made (see alert_layer.cpp as an example).

When hovering over the time in the upper right of the map, expand the status window to display detailed radar product information.

Asynchronous threads are outliving their parents. Some of this has been mitigated with the use of mutexes, but not completely. Because the thread pools are managed outside the object lifecycle, work posted to boost::asio does not ensure the completion prior to parent objects being destroyed - this must be managed by the objects. This is becoming more apparent now that animation is implemented, and the chance of a crash upon object destruction is increasing.

Thread pools should instead be managed by the objects that spawn threads. An example and partial fix is in 1c159a3.

Warnings should be animated along with the radar scans. The timeline manager emits a SelectedTimeUpdated() signal, which can be used to render warnings active at the selected time.

I joined the discord server listed in the readme twice, and both times it had disappeared from my list. Is it an issue on my end or had I been kicked?

Thanks!
