Filter POTA/SOTA Spots

[W6CZ]

Add filters for mode, band

[alanhargreaves]

There are lots of feature requests for this functionality. Now that we've got POTA, SOTA and WWFF Panels using a lot of the same code, this is something that we can start thinking about how to implement.

[alanhargreaves]

and as a starting point, the Band selector ribbon on the map will filter display of all POTA, SOTA & WWFF spots on the map in the current version, though t does not affect the display in terms of distinct panels.

OK, I'm taking the bait, I'll have a look at creating filters for any of the panels showing up in POTA, SOTA, WWFF, ... Basically anything that's using the ActivatePanel code.

I'm thinking about using the PSK Filters as a basic starting point, though that is a BOATLOAD of possible modes in there! Anyway, the filters I'm thinking about to start off with are:

• band
• mode
• grid regions

The grid regions stuff is going to need a little extra work in the hooks code to ensure that we add Grid locators to WWFF and SOTA, as unlike the POTA spots, these don't provide a grid locator. Fortunately there is a library in npm that we can use for the mapping (I much prefer to use someone's existing code if it already exists rather than rewrite it) in @hamset/maidenhead-locator, which we can use like:

import { WGS84ToMaidenhead } from '@hamset/maidenhead-locator';

// Example coordinates (e.g., San Jose, CA, used in the library docs)
const latitude = 36.75;
const longitude = -119.5;

const coordinates = { lat: latitude, lng: longitude };
const gridLocator = WGS84ToMaidenhead(coordinates);

console.log(gridLocator); // Output: 'DM06gs'

The other thing I want to try is to make the code as common as I possibly can for anything using the ActivatePanel code.

I'm noting ideas like the above here so that I don't lose them from my google searches.

@alanhargreaves Alan I am going to assign you to any of the requests that have to do with this in my current issues list

Good Progress over the weekend. I have filters working under Dockable for everything that uses ActivatePanel.

I'm basing the filtering off the Band, Grid, Mode filters in the PSKReporter.

I suspect that what I've done will have broken Modern, so I need to get that addressed.

I'm also writing up as I go what needs to be added for the filters, as it's got its fingers in all kinds of surprising places in the code. I need to add those to a (yet to be written) document on how to add panels using ActivatePanel.

[alanhargreaves]

Filters and Callsign labelling are now working in Modern. I suspect that the documentation is going take longer than the work.

This was addressed in #584 and is now public.
