# Contour Creator 🗺️
|
||
This program takes a tiff heightmap and produces vector contours.
|
||
This is our project for the INF205: Resource-efficient programming course
|
||
## Status
|
||
- [x] Read .tif file into memory using gdal
|
||
- [x] Run the marching squares algorithm and produce a "cellmap"
|
||
- [ ] Use a lookuptable to produce a vector file from the "cellmap"
|
||
## Dependencies
|
||
- GDAL >= 3.5
|
||
- OpenMP
|
||
- CMake
|
||
|
||
If you want to clone the repo with the example files you need [git-lfs](https://git-lfs.com/) installed and activated with ´git lfs install´
|
||
To install the packages on Fedora run
|
||
```
|
||
dnf install g++ git-lfs cmake gdal-devel
|
||
```
|
||
on Debian:
|
||
```
|
||
apt install g++ git-lfs cmake libgdal-dev
|
||
```
|
||
## How to build:
|
||
```
|
||
mkdir build
|
||
cd build
|
||
cmake -DCMAKE_BUILD_TYPE=Debug ..
|
||
cmake --build . --parallel
|
||
```
|
||
Then you can run `./contour-creator PATH/TO/HEIGTHMAP.TIF`
|
||
Run an example file: `./contour-creator "../example_files/Follo 2014-dtm.tif"`
|
||
Currently the program outputs to ´out.shp´ in the current directory.
