I think this is the thread for this, yes? A site I found for those who are in the mood to have absolutely every resource (pretty much) at their fingertips:
[SEED:iTCzK3bDMUbcSMSHE7Cq]

Embark example:
Features:
-Major river (or lake depending on embark shape)
-Volcano
-Both sand and clay IN the volcano's caldera rim right by the surface lava.
-Fire clay only a few blocks away from the volcano rim
-Marble flux
-17,000+ hematite even in my smallish embark shape shown here, including a lot visible right on the surface.
-Great variety of other metals - tetra, gold, aluminum, candy, malachite, and galena
-Layer stones are mostly metamorphic and igneous types of stuff (basalt, andesite, rhyolite, gabbro, slate, etc.)
-Medium forest coverage
-Some good colors to work with in limited quantities: orhtoclase, olivine, malachite, cinnabar, microcline
-Underground is not super deep, not good for large projects or hugely sprawling forts. IS probably good for FPS and for cavern resource access.
-Only one cavern, open structure
-The river basin is aquifer, the hills with the volcano are not, so you can circumvent but still use as desired
-Cavern water is just SW a bit from the volcano tile
-The hillsides are realistic looking, no bizarre dramatic square shapes.
