Creates a gamescript (in ./town_placer/townplacer) that will automatically place
towns according to certain assumptions about the map corners and map size.
Given a fill origin and height and grayscale PNG, fills water on the map.
Creates a gamescript that will automatically place trees according to a grayscale image.
Drops signs programmatically based on PoI from a dataset.

Go to USGS EarthExplorer Select a region and download both the Void Filled and water body data. Save in data/scenarios//height and data/scenarios//water
-
Go to https://earthenginepartners.appspot.com/science-2013-global-forest/download_v1.2.html Download the tiles in the area you are interested in. Save in data/scenarios//trees
-
Go to http://gaia.geosci.unc.edu/rivers/ Download the rivers that you need. Save in data/rivers
-
Go to https://download.geonames.org/export/dump/ Download the GeoNames for the countries you need. Use https://www.geonames.org/countries/ to identify the ISO-3166 alpha2 codes. Delete the readmes in the zip files. Save in data/geonames
Rivers and GeoNames are stored in the terrain/data directory Trees and USGS EarthExplorer data due to their size can be stored in per-project folders, to be deleted to clear up disk space as needed

Load in the height map tifs in MicroDEM
-
Scale up to a generous amount (100% is ideal) and then generate the following two files:
6.1. A coast file -- elevation color -1, 0, 1, save as geotiff Save as data/scenarios//base_coast.TIF
6.2. A height file -- elevation color, grayscale, 0 to whatever the max. Save as data/scenarios//base.TIF
-
Run build_stack.R after configuring scenario_name, river_scale, and map_crs the way you want in parameters.R
-
In GIMP, stack together all the files and then perform crop/scale to get the scenario file you want
