The system is built upon plugins integration, then many community extensions have shown up to expand upon the base features of the library. Leaflet is based on WebMercator projection and does not provide an easy way to change the projection. Also, it is harder to interact with OGC standards, and to use custom projections. The drawback of this approach is that the library does not provide the full palette of geospatial features, if you want to build more advanced user interfaces, you will have to rely on plugins very quickly. It provides a simple API, everything is made so it is easy to embed geospatial information in a website: if you want to display a map with tiled background layers (OSM, satellite), plus some custom vector data (geojson) on top of it, you’ll find the experience great and straightforward by using Leaflet, and the result will clearly respond to your need.Įnter fullscreen mode Exit fullscreen mode It’s a lightweight library that focuses on displaying fast maps on the web. Note that the article reflects my own knowledge, experience and opinion about what each library covers and provides, I am objective but humble enough to admit I don't carry the universal truth.Īs a good map worth more than a long speech, let’s discover them.Ĭreated in 2010 by Vladimir Agafonkin, Leaflet has been the first library to take advantage of new HTML 5 features, like the Canvas rendering, offering modernity and great performance. I’m going to introduce you to the 3 best open source alternatives, they are free to use and you’ll see it is not that hard to implement your own mapping application. You probably want to make your data a bit more explicit through maps, and you don't feel comfortable being captive in the Google Map API ecosystem: welcome to the open source world. You consult maps to see elector distribution, covid expansion, people migration, land use, disaster impact and for many other reasons. Now let us style our heading and change it’s color, just to see if our css and html code is working in our browser.Maps are everywhere nowadays, most of the people are using for instance Google Maps on a daily basis to find a place or follow a route. What you should be seeing now is the title which says World Population Map and our heading below in all caps. I am using Google Chrome as my web browser. Let us save it and double click the map.html file, in order to run it in our browser. Here is the full code we have so far: World Population Map HEADING We will call the title of the page World Population Map as seen below: World Population Map Īnd here we will just print heading in capital letters. Next we will add a tag inside our tag, and then we will add an (heading) tag inside our tag, and then test if we can display it on our web page. So let’s open our map.html file in a text editor of your choice, and add the following code: We want to create a standard HTML5 template, and test if our markup code works properly in our web browser. The map.html file will contain our front-end code, and the server.py file will contain our back-end code. One will be our map.html file, and the other will be our server.py file. Step 2: Create the project files inside the folderĬreate two files inside the project folder. Step 1: Create the project folder at the location of your choice HTML5 - We will use this to create our web application. Leaflet - We will use Leaflet as our mapping library and our front-end code. Python3 - We will use Python3 to create our back-end server. The following will be the tech stack that we will be using to build our web map: Python 3 Script to Build a Sitemap Generator Crawler and Download Sitemap XML File for any Website
