Google old school runescape map12/31/2023 This is a MASSIVE amount of work, and hard to do in a performant way. You have to implement all the logic of turning all the data into triangles (tessellating lines, breaking down polygons, implementing anti-aliasing, figuring out collision detection between labels) from scratch, reimplementing difficult computer graphics algorithms from decades ago. The only option is WebGL, which is basically a very efficient way to draw triangles. Rendering vector data on the browser with the level of detalization necessary for modern cartography (hundreds of thousands of points in a single view) is not possible with the usual technologies like Canvas & SVG. Leaflet avoids all the complexity by relying on all the rendering done on the server, while all it has to do is load images. It's my first go-to for interactive map rendering and even non-map stuff, like zoomable gigapixel photos. The main thing I had to do was transform their XML into GeoJSON on our webserver (their backend had only rudimentary GeoJSON support at the time - I think their internal teams either refused or were not allowed to update it?).Īnyway didn't mean to write a mini-blog post shilling Leaflet, it's a great library, my first experience of it was that it saved a seemingly doomed project, it does exactly what it says on the box and not much else, which is perfect when it's just a small component of a much larger and more complex project. Leaflet enabled the solution by being compact, only did the thing it was designed to do and didn't interfere elsewhere, and the plugins were tiny, did their job, and did it much more transparently. I replaced weeks of frustrating spaghetti code and rebuilt a faster and more stable solution in a couple of days, polished it up after getting the "nod" and the site was finally ready to launch a couple of days later. Design compromises were being considered to get the job over the line.Įnter Leaflet which was considered risky and new at the time, but on a whim and my own time I threw together a quick demo and got permission to spend a few days on it. The mapping became a blocker on the project as the weeks wore on - hammer down one gopher, and another head would pop up. The specification pushed one of the more popular JS mapping heavyweights of the day (I forget which) which due to the specific mix of required features ended up being painful, slow, janky, and with mobile-responsive becoming the frontend de-jure, a battle against nested layers of opinionated templating abstractions, all of which added up to a couple of hundred KB of dependencies and endless fragile callback-induced race-conditions, slow round-trips to their geoserver, and XML parsing issues. By design this all required a round-trip to their geoserver which did a spatial query. The design and data called for thousands of nested POIs all searchable by a range of filters (facilities, activities, etc), with pop-up info boxes and automatic clustering groups, with a custom layer from their XML-based geoserver full of park boundaries (polygons) which could filter the POIs within. The first time I used it was to map parks and facilities for a state parks department, must have been in the early 2010s?
