comment A global, grid-like projection for creating heatmaps
@whuber - Thanks. I've updated the question with an edit and a screenshot to try and further clarify the use-case.

@AnserGIS - The calculation will happen on a projected plane. The rectangular data may cover multiple grid cells. See also the edit for more information.

comment A global, grid-like projection for creating heatmaps
@whuber - You raise fair points but please trust that I'm aware of all that but believe it's generally irrelevant in this use-case, hence glossing over it. I'm showing a super-aggregated, very-high-level map that will indicate usage of a service. Source data ranges from ~30m resolution to 100km. I'm aggregating to grid cells of 1km upward. Unfortunately I don't know enough about projections to know about the advantages/disadvantages of each (and there are a lot), hence this question seeking based on what it'll be used for.

@AnserGIS - The raw data is rectangular in nature, although some may be points to. I'm then counting how many of them are intersecting each of these grid-projection cells. See my other comment for why I'm not over-concerned about statistical accuracy.

comment A global, grid-like projection for creating heatmaps
@whuber - The data will be used for general representation to lay-users, not any form of spatial analysis. Thus no particular preference relating to which geographical properties are kept/lost and MAUP is irrelevant as I'm seeking a gross generalisation of the data. I only need the grid-squares to neatly overlay something like OSM tiles. My desire for vector is because I'm storing it in a database and it's much easier to manipulate.

comment A global, grid-like projection for creating heatmaps
@John - Thanks; I came across the Military grid in my own searches, but it uses letters as well as numbers so I'm not sure it's suitable. The USNG stuff looks interesting but I'm not seeking to create my own.

I wonder if you could invite your own coordinate system? Or use one that doesn't have a fixed datum>
