## Group: Trygve and Esther
|
|
# Functionality
|
|
Our program usees the marching squares algorithm to create a vector contour map from a raster heightmap.
|
|
The cli interface is `gdal_contour [OPTIONS] <src_filename> <dst_filename>` with these options:
|
|
```
|
|
-i <elevation intervall> Interval between contours
|
|
-f <format> Fileformat to output
|
|
```
|
|
# data structure and input/output

|
|
# Responsibilities:
|
|
Esther will create the algorithm itself with multitreading. This will essentially be a function that takes a grid of pixels as input and returns a similar grid of cells.
|
|
Trygve will take care of reading in the tiff file into our own datastructure and creating a vector image from the output of the algorithm.
|
|
|
|
# How do you plan to make it easily verifiable that your objectives are reached?
|
|
We can compare against the `gdal_contour` cli program which is a implementation widely used in other software. We can compare speed, memory usage and the result itself.
|
|
Each step in our program also produces a output which we can be worked on and evaluated independently. |
