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 🙏

Terria logo

TerriaJS is a library for building rich, web-based geospatial data explorers, used to drive National Map, AREMI and NEII Viewer. It uses Cesium and WebGL for a full 3D globe in the browser with no plugins. It gracefully falls back to 2D with Leaflet on systems that can't run Cesium. It can handle catalogs of thousands of layers, with dozens of geospatial file and web service types supported. It is almost entirely JavaScript in the browser, meaning it can even be deployed as a static website, making it simple and cheap to host.

Features

  • Nested catalog of layers which can be independently enabled to create mashups of many layers.
  • Supports GeoJSON, KML, CSV (point and region-mapped), GPX and CZML file types natively, and others including zipped shapefiles with an optional server-side conversion service.
  • Supports WMS, WFS, Esri MapServer, ABS ITT, Bing Maps, OpenStreetMap-style raster tiles, Mapbox, Urthecast, and WMTS item types.
  • Supports querying WMS, WFS, Esri MapServer, CSW, CKAN and Socrata services for groups of items.
  • 3D globe (Cesium) or 2D mode (Leaflet). 3D objects supported in CZML format.
  • Time dimensions supported for CSV, CZML, WMS. Automatically animate layers, or slide the time control forward and backward.
  • Drag-and-drop files from your desktop to the browser, for instant visualisation (no file upload to server required).
  • Wider range of file types supported through server-side OGR2OGR service (requires upload).
  • All ASGS (Australian Statistical Geographic Standard) region types (LGA, SA2, commonwealth electoral district etc) supported for CSV region mapping, plus several others: Primary Health Networks, Statistical Local Areas, ISO 3 letter country codes, etc.
  • Users can generate a reusable URL link of their current map view, to quickly share mashups of web-hosted data.

Not Data61

Sites we're aware of that are using TerriaJS. These are not endorsements or testimonials.

Technical

  • Built in ECMAScript 2015, compiled with Babel to ES5.
  • Supports IE9 and later. A few features require IE11+.
  • TerriaJS Server component runs in NodeJS and provides proxying for web services that don't support CORS or require authentication.
  • Dependencies are managed in NPM and assembled using WebPack.

Getting Started

The easiest way to build your own Terria-based map is using the TerriaMap starting point. This gives you the HTML structure, server and build processes you need to get a site up and running immediately.

See Getting Started in the Documentation for all the details.

Components and naming

  • Terria™ is the overall name for the spatial data platform and the team that built TerriaJS.
  • TerriaJS is this JavaScript library consisting of the 2D/3D map, catalog management and many spatial data connectors.
  • Cesium is the 3D WebGL rendering library used by TerriaJS, which provides many low-level functions for loading and displaying imagery and spatial formats such as GeoJSON and KML.
  • TerriaMap is a complete website starting point, using TerriaJS.
  • TerriaJS-Server is a NodeJS-based server that provides proxying and support services for TerriaJS.
  • NationalMap is the flagship Terria deployment, and the origin of the TerriaJS library.

Related components

  • Catalog Editor, an automatically generated web interface for creating and editing catalog (init) files.
  • Generate-TerriaJS-Schema, a tool which automatically generates a schema for validating catalog files, and also the editor, by processing TerriaJS source code.
  • TerriaMapStatic, a pre-built version of TerriaMap, which can be deployed as a static HTML website, such as on Github Pages.
