lens	what it shows
material	What every voxel is made of: the material colour of the top of each column.
era	The era that laid each built voxel; untouched ground is greyed. The palimpsest itself.
water	Standing water, saturated soil and the river: what the water model holds this month.
cultures	Town ground in the colour of the people who hold the nearest settlement.
territories	Town ground by settlement number, whoever lives there.
fertility	How well each column grows things, one being the site's ordinary ground.
snow	Snow, firn and glacier ice lying on the ground as voxels.
traffic	Where people actually walk: crossings this decade, and the wear they leave.
