Support the capability for users to provide their own SLD URLs for layers in the GeoGIF configuration and front-end

GeoGIF must be able to provide (A) its front-end (the GIF/movie creation form) and (B) the text at the bottom (legend + logos + any text) in multiple languages.

Potential improvement: show estimated output file sizes, both for the GIF and movie formats. This information will be very useful for users, especially in the use case where the output needs to be shared through email or Twitter.

Output file size varies according to the output dimensions (e.g. 600x400), format (GIF vs movie), number of frames per second, selected file compression, etc.

Both in the yaml configuration and the front-end, users should be able to select one of the NRCan GeoBase WMS layer to be set as basemap.

I suggest we use the 3 WMS basemap layers from NRCan that we used in DQD:

• GeoBase
• Canada Base Map - Transportation
• NRCan Atlas of Canada

On the GoC Open Data I don't think we find these exact 3 layers,

Automatically update the data source capabilities.

• fixed time intervals
• every time a layer is picked in the menu

GeoGIF should have the GoC OpenStreetMap layer as its default basemap.

This basemap will probably be available from the TMS and/or WMTS standards. The final URL for accessing this layer is not yet known.

Support and add option in the front-end for layers to be animated with a user-determined transparency, on a layer-by-layer basis

It would be pertinent for GeoGIF to support TMS and WMTS layers as data sources. Such as for supporting the GoC OSM tiles as basemap.

These functions should be added in the db management tool

• Modify info
• Remove sources
• Change update frequency

In GeoGIF's front-end, users would greatly benefit from having the selected layers showing up directly in the BBOX selector after being added.

I would display the first timestep of enabled layers. Comments / suggestions welcomed :-)

It could be useful for the GeoGIF front-end to be able to keep a user-generated animation for a specific period of time, say 10 days, and provide the user a static URL to access the animation.

• The option to keep the animation should be 'disabled' by default
• The 10 days maximum is to ensure the filesystem is not filled. That said, if this feature becomes popular, we'll have disk space issues.
• An extension of this feature request would be to provide a list of available animations on the server, their permanent URL and their deletion time

Any other suggestion welcomed :-)

Add the capability of including layer legends in the output animated GIF. Either on the map or better, in the bottom panel.

Display ECCC logo if any MSC layer is used in output, ideally in the bottom section in order to avoid hiding content.

Adding logging capability and log outputs with the Python logging module will greatly help development and debugging. Thanks!

As suggested by Pascal Normand, we can add an option to enable 'motion interpolation' for video output.

This uses existing frames to output a video at a higher frame rate with content being spatially interpolated to move smoothly. This works wonderfully for radar and satellite imagery (and most of MSC GeoMet's content) and generates outstanding-looking outputs.

I can't seem to be able to create a second animation once a first one is successfully created. I systematically get the 'error' message. This happens even if I reload the page, leading me to believe this is server-related.

Please investigate. Once #19 is implemented, it's going to be easier to troubleshoot. Thanks!

the time should be set to right extent

I think it makes sense that the output GIF/video informs viewers of how this output has been generated. I suggest in small note shown at the very latest frame of the GIF/video that mentions "Made with GeoGIF".

Ideally we should also find a way to put a link to the project page. We could point to the GitHub location? Comments / suggestions welcomed!

This ticket is to find and add major cities WMS layer to the default WMS servers selectable from the GeoGIF front-end (in the box currently named "WMS url").

This must cover at least major Canadian cities, but even better if it's worldwide. Background must be transparent in order to show underlying layers. Example of major cities for Quebec includes Montreal, Quebec City, Gatineau, Sherbrooke, Saguenay, etc.

We need a way to display the timestamp in the corresponding animation frame.

It could be a simple numerical timestamp or a visual widget. Please propose suggestions :-) Thanks!
