GTiff2Tiles
Analogue of gdal2tiles.py on C#. Currently support only GeoTIFF as input data and creates only EPSG:4326 geodetic tiles on output in tms structure.
Solution is build in VS2019 (16.1.1), .NET Framework 4.7.2, targeting Windows x64 systems.

Information about changes since previous releases can be found in changelog. This project supports SemVer 2.0.0.
Previous versions can be found on releases and branches pages.
Examples
In Examples directory you can find GeoTIFFs for some tests.
GTiff2Tiles.Core
GTiff2Tiles.Core is a core library. Here’s the API documentation.
Library uses 2 different algorithms to create tiles:
- Crop – crops all the zooms from input file;
- Join – crops the lowest zoom from input file and then joins the upper images from built tiles.
Also I should mention, that if your input GeoTIFF is not EPSG:4326, it will be converted by GdalWarp to that projection, and saved in temp directory before cropping tiles.

GTiff2Tiles.Console
GTiff2Tiles.Console is a console application, that uses methods from core to create tiles.
Usage
| Short | Long | Description | Required? |
|---|---|---|---|
| -i | --input | Full path to input file | Yes |
| -o | --output | Full path to output directory | Yes |
| -t | --temp | Full path to temp directory | Yes |
| --minz | Minimum cropped zoom | Yes | |
| --maxz | Maximum cropped zoom | Yes | |

Detailed options description
input is string, representing full path to input GeoTIFF file.
output is string, representing full path to directory, where tiles in tms structure will be created. Should be empty.
temp is string, representing full path to temporary directory. Inside will be created directory, which name is a timestamp in format yyyyMMddHHmmssfff.
minz is int parameter, representing minimum zoom, which you want to crop.
maxz is int parameter, representing maximum zoom, which you want to crop.
algorithm is string, representing cropping algorithm. Can be crop or join. When using crop, the input image will be cropped for each zoom. When using join, the input image will be cropped for the lowest zoom, and the upper tiles created by joining lowest ones.
threads is int parameter, representing threads count. By default (if not set) uses 5 threads.
