QUESTION

Rendering curved flight paths from geojson file

Asked 2021-Apr-05 at 11:39

I'm working on a Laravel based application where users can create flights and then view the flight routes on maps. Some of these maps consist of up to 10.000 flights. With these numbers Mapbox would sometimes crash the browser or take a really long time to render, especially since we were using arc.js to calculate the Great Circle routes.

We then switched to creating the flight routes as a single geojson file that was then loaded directly by Mapbox. The maps now load really fast (1-2 seconds instead of up to half a minute), but the routes are straight and do not cross the dateline, which is a real problem as that's not how planes fly.

First I looked for some type of setting within Mapbox that would allow me to render lines as great circles, but I couldn't find anything. Next I looked for PHP libraries similar to arc.js to output the routes to the geojson file, but while there are plenty of libraries that will calculate the distance based on a great circle, I didn't find any that actually produce a route. Currently, I'm looking at the database level. We already use PostGIS, so I thought that there might be a way to use it to calculate the route. So far I have this here, cobbled together from various sources, but it's still throwing errors; ST_MakeLine does not exist...:

QUESTION

Animating D3 Arcs, with an Arc for each bound data point

Asked 2020-Dec-27 at 21:47

I'd like to be able to animate multiple (based on the data) arc charts from one percent (angle) to another in D3.js and can draw them fine initially.

However, after much hunting around, I'm stuck with the animation. Below is the code that does the original drawing and then two options for animation to subsequent values. I'm using groups for each Chart Node as I will be adding multiple elements to each.

Option 1 uses standard interpolation which I know doesn't work properly as the shape is too complex. So the animation doesn't follow the correct steps and also errors are reported to the console.
Option 2 uses the Arc Tween method, but this just reports errors.

To see each option working, comment out the other one.

Ideally, I'd like to be able to create an arc function to which I can pass the innerRadius, outerRadius and then the endAngle. For at least the endAngle, I want to be able to choose to pass a constant (e.g. 0) or Bound Data (e.g. d.pct).

Use leaflet-arc in Angular?

Asked 2019-Feb-21 at 12:57

How do I use the leaflet-arc plugin in Angular? What I've tried so far:

npm install --save leaflet-arc
Add "scripts": ["node_modules/leaflet-arc/src/leaflet-arc.js"] to angular.json.
Add import '../../../node_modules/leaflet-arc/src/leaflet-arc.js'; to my-component.component.ts.

However when I do the following inside my-component.component.ts, it still gives me an error that Property 'Arc' does not exist on type 'typeof Polyline'.:

L.Polyline.Arc(...)

When I do ng serve this actually works, but it still gives the error when compiling.

Any ideas?

To make it work you need to follow these steps:

QUESTION

Organizing project components — does this need to be alphabetic?

Asked 2018-May-23 at 22:10

I have a React project built in a framework called ARc (https://arc.js.org). It uses something called "atomic design" to arrange the components. The tree looks like this…

/components/atoms /components/molecules /components/organisms /components/pages

… where atoms are very primitive components (inputs, buttons), molecules are compound primitives (say an input plus a label and a feedback message component), organisms are collections of molecules (say, a form), and pages which are hopefully self-explanatory.

I like it quite a lot, but it hasn't scaled very well for our project. We're now at ~100 components, and would prefer to break this stuff down into folders like "accounts" and "checkout".

As a first step, I renamed our "atoms" folder to "primitives" and "molecules" to "widgets", and everything broke pretty much immediately. I found that by naming them "_primitives" and "_widgets" things would go back to normal, but… this can't be right, can it? Does webpack work alphabetically? Does the Atomic React thing only work because "atoms, molecules, organisms, pages" are words that are in alphabetical order??

...

ANSWER

Answered 2018-May-23 at 22:10

This turned out to be due to a peculiarity in the specific React framework that I was using. It preloads components into an object for easy retrieval. This works in ARc because it uses a bottom-up sequence that guarantees that a dependent component will already be loaded, but falls apart if the order isn't quite right.

Not a webpack issue. Thank those of you who took a few minutes to be stumped on this.

Pass data from component to action and saga using ARc/React/Redux

I'm using https://arc.js.org/ to setup a new project and am confused on how data is passed about.
