Folder: SC4M Earth 2x3 Relief
I have included an .SC4M map of the '05_Earth_769x513_2x3_Relief' map in a new folder. To load the map in SC4 Mapper, click on 'Create Region' and select 'Grayscale'. SC4 Mapper creates the city files and a config.bmp file by default, but not a region.ini file. A region.ini file is included in the folder which may be cut and pasted into the Region folder SC4 Mapper creates. Included above are 2 new previews (to the right) showing an image from SC4 Mapper, and the rendered map in 'SC4 Region View.'
FOR ALL OTHER MAPS using the SC4 in-game Map Renderer
From the unzipped 'Regions' folder select any or all of the sub folders, cut and paste into your user '/Documents/ SimCity 4/Regions' folder. Each of the Regions will then appear in your 'Region' menu in the game with the same name as the folder. Each folder contains a region.ini file and a config.bmp file, defining the name and layout of the region.
The 'Earth Signature' region is a 1x1 large city tile, containing only one large blank terra-formed tile. This folder also contains 1 city file (662k) named 'City - New City.sc4'. This region does not have to be rendered and may be viewed and used immediately in the game. The city has not been 'Start'ed so is still named 'City - New City.sc4'.
All other region folders only contain the region.ini and config.bmp files, the maps must be rendered in SC4 region view using the included grayscale heightmaps in .bmp (256 indexed grayscale 8-bit) format.
The grayscale heightmaps in this package were hand designed for use with the SC4 in-game map renderer using a popular color relief map. If you use SC4 Mapper or Terraformer, smoother surfaces and smaller file sizes may be achieved, but elevation interpretation is different, generally the water level is one increment shallower, some land area may go under.
Instructions for rendering the maps with SC4 can be found at the bottom of this page.
- SCALING in SC4 3D SPACE:
The maps are not proportionally scaled either horizontally or vertically, they only represent a general idea of area and height.
Horizontally, the term 'tile' is used for both the grid of squares in the city view and the grid of cities in the region view. One city view tile is 16m x16m, and one large city tile in region view is 4km x 4km.
Grid lines in city view may be toggled on/off by pressing the 'g' key. Grid lines in region view may be switched on/off by checking/unchecking 'Show City Boundaries'.
Vertically, buildings are scaled in (cubic) meters, but land area and elevations are more often very disproportional. In my 'Earth Relief' map one increment of land in region view is about equal to 1800m, so 5 increments from sea level is the highest point on Earth at near 9000m.
There are 62 (62 x 1800m) increments from the bottom of the sea in SC4 to the top of its 3D space, sea level cannot be raised or lowered from its 6 increment setting. In terms of my 'Relief Map' then 6 x 1800m is the deepest surface below sea level at 10,800m, almost 11 kilometers. Actual scientific measurements indicate about the same depth.
Consistently, the top of SC4 space is (62 x 1800) 111,600m, about 112km above the solid surface of the Earth. Objects below about 160km in orbit are considered to be below "Low Earth Orbit". The International Space Station orbits at about 3 times the height of SC4 space in the same spherical area defined as the 'Thermosphere' of the Earth.
- INSTALL INSTRUCTIONS:
1.) Launch SC4. In Region View use the Load Region scroll menu to locate and open the region you want.
2.) In Region View press CTRL-ALT-SHIFT-R. You should now have a window in the top-left corner.
3.) Navigate to the 'Earth Grayscale Heightmaps' subfolder in the unzipped 'SC4 Earth Maps 256 Grayscale' folder.
4.) Scroll to the bitmap (.bmp) corresponding to the region you have selected and click 'Okay'. (The exact file names of the region and map must match)
The simulator should begin processing the map. If successful, you will see the region with city layout. The processing takes from a few minutes to several minutes to complete.
What's New in Version 1.2.0
Added SC4M file for 2x3 Relief Map. Added 2 previews, edited texts.
