.. dfhack-command:: prospect
:summary: Shows a summary of resources that exist on the map.
It can also calculate an estimate of resources available in the selected embark
area.
Usage::
prospect [all|hell] [<options>]
By default, only the visible part of the map is scanned. Include the ``all``
keyword if you want ``prospect`` to scan the whole map as if it were revealed.
Use ``hell`` instead of ``all`` if you also want to see the Z range of HFS
tubes in the 'features' report section.
Examples
--------
``prospect all``
Shows the entire report for the entire map.
``prospect hell --show layers,ores,veins``
Shows only the layers, ores, and other vein stone report sections, and
includes information on HFS tubes (if run on a fortress map and not the
pre-embark screen).
``prospect all -sores``
Show only information about ores for the pre-embark or fortress map report.
Options
-------
``-s``, ``--show <sections>``
Shows only the named comma-separated list of report sections. Report section
names are: summary, liquids, layers, features, ores, gems, veins, shrubs,
and trees. If run during pre-embark, only the layers, ores, gems, and veins
report sections are available.
``-v``, ``--values``
Includes material value in the output. Most useful for the 'gems' report
section.
Pre-embark estimate
-------------------
If prospect is called during the embark selection screen, it displays an
estimate of layer stone availability. If the ``all`` keyword is specified, it
also estimates ores, gems, and vein material. The estimate covers all tiles of
the embark rectangle.
.. note::
The results of pre-embark prospect are an *estimate*, and can at best be
expected to be somewhere within +/- 30% of the true amount; sometimes it
does a lot worse. In particular, it is not clear how to precisely compute
how many soil layers there will be in a given embark tile, so it can report
a whole extra layer, or omit one that is actually present.
