Multiple map overlays

[IanMayo]

We don't expect the coastline map to change (yellow land & light blue sea).

But, we can expect the above & beneath water environments to change,

We should probably also include support for switching either environment on/off, like layers.

In order to allow both layers to be viewed at once, they'll have to be semi-transparent. So, I guess the datafiles (json) that represent them will have to include:

• series of cell references, each with the category
• key of categories, with: 'name', 'color', 'alpha'

We can also then put a key on the map, potentially at the bottom-left.

If we do have a layer manager, maybe it will be implemented in HTML. But, until we get some momentum in HTML side, d3 will do.

You mentioned the concept of pan/zoom #8 . If this was on a toolbar (floating or not) we could include a drop-down with checkboxes to switch layers on and off.

Much later on, that drop-down menu could include "Command Intent" - large simple labelled shapes that describe their rough intent, or the range of courses of action being considered.

A simpler solution would be to have a function which redefined the “type” of the hex data (and therefore recolours the hex’s). What I meant was that I’ve guessed at the colours for the 5 types defined in the hex data MWC sent us. Would be good to have a key for what each number represents and the ‘correct’ colour.

Not sure where we are with this one? My suggestion:

• instead of overlays allow white cell to redefine the "type" of the hex data at the start of a Turn
• allow white cell to mark certain "types" as inaccessible (by vessel type? ie a helicopter could go on land but a submarine couldn't)

These can just be programmed into the current code quite easily.

@BMPMS - I've just gone back through my emails, and found this:
type was (i think), 0 for sea, 1 for land, the rest for types of sea.

There are three blue shades. To give us something to go on, I'll label them (from lightest to darkest):

• Shallow Water
• Deep Water
• Ocean Front

@IanMayo I’ve applied these for now. FYI the colours are made up by me from colour brewer rather than those used by MWC on the hard copy hex maps.
