HMAPGEN

A simple library in Go to generate heightmap images of a given location.

Prerequisite

In order to generate the heightmap, you must have at least an Api key for the following services:

• IGN Elevation API
• BING Elevation API

USAGE

import (
  "github.com/michaelvial/hmapgen"
)

// South, West, North and East Lat/Lng coordinates 
area := ["45.142724","6.0888359","45.7316515","7.1368806"]

// Available options
options := hmapgen.Options{
    Service: "bing",  // Either bing or ign
    Key: "xxx",  // The API key for the elevation service
    Precision: 1000,  // Interval between each points (in meter)
    File: "./images/output.png", // Heightmap filename
}

// Heightmap generation
hmapinfo, err := hmapgen.GenerateHeightMap(area, options)

// Filename
fmt.Printf("Output file:", hmapinfo.Filename)
// Diff between the lowest point and the highest point (in meter)
fmt.Printf("Height offset:", hmapinfo.HeightOffset)
