Geografi

Projektet indeholder to moduler

• taylor, der er en Go implementering af Chuck taylors oprindelige WGS84 konvertering mellem lat/lon og UTM
• utmabs, der er en omregning fra Military Grid System (MGRS) til UTM.

Installation

Clone projektet https://github.com/brundtoe/go-geografi.git

test

Modulet taylor

    cd pkg/taylor
    go test -v 

Modulet utmabs

    cd pkg/utmabs
    go test -v 

Modulet geoutm er en justeret kopi af https://github.com/klaus-tockloth/coco, som er en delvis portering til golang af https://github.com/proj4js/mgrs

Overview

Original Javascript by Chuck Taylor Port to Go by Jackie Brundtø

This is a simple port of the code on the Geographic/UTM Coordinate Converter (1) page from Javascript to Go. Using this you can easily pkg between UTM and WGS84 (latitude and longitude). Accuracy seems to be around 50cm (I suspect rounding errors are limiting precision). This code is provided as-is and has been minimally tested enjoy but use at your own risk! The license is the same as the original Javascript:
