A library to generate static map from OpenStreetMap tiles or Google Map Static Map

motivation

Alternative approach to generate capture map without using headless browser. Inspired and based on flopp/go-staticmaps

install

go get github.com/galihrivanto/petastatis

simple usage

import (
	"log"

)

type Label struct {
	Lat  float64
