Hi, I've recently created a fork of your mod and implemented some changes. If you are still working on the project, and if you want to, you can view the changes and decide if you want to merge the changes or not.
In any case, I will probably create a standalone mod with a UI, based on the changes and more functionalities sometime in the future.

The link to the fork is https://github.com/DavixDevelop/GeoSkylines
And the link to the Reddit post talking about the changes https://www.reddit.com/r/CitiesSkylines/comments/1i2vm77/11_forests_from_tree_cover_data_containing_forest/

What is the relation between this mod and https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2134693817
Both point to the same GitHub page.

will be fun , can not wait to see them arrive

hey all, please bear with me. Soon I'll finish my thesis and then I plan to create instruction vidoes which will make the use of this mod easier

Hey I read your paper and dearly want this mod to work, but I'm having trouble like others below. Any hotkey command I invoke puts up the error of missing import_export.txt in C:/temp folder.

I have created and detailed an import_export.txt file in both this location and the steamapps folder as you advised.

Might an issue be the fact I have my steam folder on my D drive?

Either way, I'd appreciate your help. I'd love to see my city visualised in ArcGIS.

hi , terrific u have made this, i would like to test if it works on my real location . only thing is i have never used something like this and it seems highly academic usage. i will try but if u can ever post a You Tube how to use it ( and from beginning to end. i would highly appreciate.

on GitHub, in the example folder, there are 3 folders where the import_export.txt file is. Of course it's for that particular example. But you can use it as a template. Or just create a new one. It's just a text file.
The files must be located in either C:\temp or c:\Program Files (x86)\Steam\steamapps\common\Cities_Skylines\Files
To be sure, copy it to both locations.

Hey @pinosjan , I am trying to use the ctrl P hot key function in game and i get an error box telling me that there is no file in my temp folder with the import_export name. I've looked around in both of your guides from git hub and haven't found anything on why this is happening.

See the documentation on GitHub where it's described how to do the bounding box. Actually, you don't even need that. Just pick a centre of the modeled area and find out the latitute and longitude (e..g. in Google Maps - but beware of switching lat and lon!). Write the lat lon to the import_exprt file. Then using QGIS and QuickOSM plugin download the roads. The game will then check the coordinates by itself. Anything outside the 17.28 x 17.28 box will be skipped.

Sorry, not sure about MacOS. Tested only on a Windows PC.

I wonder how it is possible to accurately do a 17.28x17.28 grid @pinosjan. Wanted to do my hometown in Slovakia - Prievidza, but can´t really figure out the map to set it up.

@pinosjan -- Does this work on MacOS? If not, I recommend posting a bolded statement at the beginning of the description.

whenever cities skylines 2 comes out (that will get rid of the road limit and all that altogether) i would be more than happy to be able to financially support your development of this mod for the next sequel

This is great. I intend on using my own DEM so your thorough documentation will be a huge help. My maximum terrain variation is <1024 metres so I should be able to create a scale model.

In the GitHub repository, there's a Word document that describes the elevation map conversion in detail. But in short, it's 16 bit unsigned, values 0 to 65535. If max elevation of your area is higher than 1024 then use it as your max, otherwise use the game's max 1024.
Yes, I used QGIS for the conversions between UTM and WGS.

This is very cool. I have some questions about projections and height maps: how did you scale your height maps? I assume they must be 8-bit but what elevation is 255? Is it just 256m based on the East-Up-North coordinate system?
Were you using QGIS for the WGS->UTM-alike Helmert transformations?

Hi, that's actually my paper :-)

Hi I found a research paper using your mod: https://www.mdpi.com/2220-9964/9/1/17/pdf#:~:text=Cities%3A%20Skylines%20is%20built%20on,can%20be%20roamed%20almost%20freely .

My new PC couldn't find the files in c:\Program Files (x86)\Steam\steamapps\common\Cities_Skylines\Files\ therefore I updated the code with option to use folder c:\temp instead.
