Heightmap Distance Calc

This tool is designed to calculate distance from terrain heightmap data. Each heightmap cell has a spatial resolution of 30m and an 11m height value.

Height maps should be 512x512 unsigned 8bit data.

It uses Bresenham's line algorithm to traverse across the terrain.

Time spent: 4 hours

Prerequisites

  • bash
  • C++ compiler (clang or GCC)
  • GNU Make

Building and Running

These are run from the root repo folder

  • make build all
  • make clean cleans the build dir
  • make test runs the test suite, builds if necessary

Data files

You will need to make a data folder mkdir data Place any heightmap data in the data folder then run. Example:

cd build
dist ../data/heightmap1.data 0,0 1,1
