Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

geocoortransform 坐标转换

简介

本模块提供了wgs84、gcj02和bd09坐标系相互之间的转换。 关于这三类坐标系的转换,其实网络上公开的有很多,但是我在应用的过程中发现有一些问题:就是gcj02或者bd09转wgs84的过程中,有几米的误差。在项目中,如果对定位精度要求较高,则不能满足项目需求。所以本模块针对上述问题,利用迭代法,重新写了相应算法,精度得到很大的提高。 支持node和浏览器引入

安装

npm install coordtransform

使用

NodeJS用法

const geocoortransform = require('geocoortransform');
console.log(geocoortransform.bd2gcj(117,39));
//geocoortransform.bd2gcj geocoortransform.gcj2bd 
//geocoortransform.gcj2wgs geocoortransform.wgs2gcj 
//geocoortransform.bd2wgs geocoortransform.wgs2bd

浏览器用法
