QUESTION
I have been trying to check if the direct distance between the user's current location and the shop's location is less than 4km. But when I move the user's marker, the distance measured seems to be less on the side areas of the shop but a lot more in the vertical up and down space of the shop, which doesn't look proportional as I am expecting a circularly consistent behavior. I have been puzzled with this behavior and can't find the solution. Any help or guidance is sincerely appreciated!

var shop = [18.565461492546987, 73.91061898347883];
Your project is operating at 74 degrees of latitude. In Web Mercator, at that latitude, there is a significant difference in pixel distance between a degree of latitude and a degree of longitude. (At the equator, there is none).
I haven't inspected your code further, but I imagine it is operating correctly - a squished ellipse is what you would expect. You can verify this by moving your shop to [0, 0]
and seeing if it gives the circle you were expecting.

document.addEventListener('turbolinks:load', () => {});
is not working as expected. Mapbox throws the following error: Uncaught Error: Container 'map' not found.
and the map only displays properly once I reload the page.

...ANSWER
Answered 2020-Dec-04 at 16:00The problem is that you're assigning mapElement
when the file is imported. Not when the DOM is ready or when turbolinks performs a page visit.
If you simply rewrite this code so that your functions take an element as an argument instead of relying on variables in the outside scope its trivial to solve it:

I am trying to use this fiddle code from Mapbox in my react app. Official code here
So far, this is my code, I am getting this error TypeError: Cannot set property 'accessToken' of undefined
I am new to React so having a hard time converting this js code. Any resources/codelinks are appreciated for reference. And how can I make mapbox work as a react component.

QUESTION
I am working with Leaflet and custom stereographic projections in the polar regions.
In this projection, I am handling dozens of marker positions that need to be clustered. Therefore I am using Leaflet.markercluster plugin.
My current problem is, that depending on zoom, the drag position of individual clusters, they disappear and reappear again.
I made a jsfiddle to make the error reproducible:
...ANSWER
Answered 2020-Nov-17 at 19:42This is due to the polar projection and Leaflet.markercluster option removeOutsideVisibleBounds
:
Clusters and markers too far from the viewport are removed from the map for performance.
The polar projection makes the map viewport bounds potentially have smaller latitude than at its center (typically when the pole is by the center, and edges are at lower latitude). In this situation, Leaflet.markercluster reads the viewport bounds, and (incorrectly in this case) concludes that the user displays the world at lower latitude, and hides the clusters and markers "far" from these bounds.
A possible solution is simply to disable this behaviour, hoping that you do not have so many markers that you would still experience poor performance:

See the answer to using require in the browser here: Node-style require for in-browser javascript?

So add this to your html:

QUESTION
I'm using Wicket 9 by including wicket-spring-boot-starter 3.0.4 .
In my demo project, it's necessary to put JavaScript at the end of . So I followed the explanations in https://ci.apache.org/projects/wicket/guide/9.x/single.html#_put_javascript_inside_page_body
I also added resources (CSS and JS) via an implementation of Component#renderHead(IHeaderReponse)
in my page.
All works as expected with Wicket 8 (from wicket-spring-boot-starter 2.1.9).
With Wicket 9 , to make my App run, I first put webApplication.getCspSettings().blocking().disabled();
in WicketApplicationInitConfiguration#init(WebApplication)
. My App starts, but the generated Page doesn't contain a section, and so the app doesn't work because of missing resources.
To make the element appear in my page with all references, I commented out all code that refers to the rendering of JavaScript in
.
But my app doesn't work with this "workaround".
Am I doing something wrong?

I'm new to coding and I want ask if there is a way to reload mapbox markers from a csv file using omnivore.csv
I've taken this example from mapbox.js here
I have tried to wrap the omnivore.csv in a function and use setInterval but that will cause the markers to keep stacking on each other.
I wanted to refresh/reload the markers every 4 min. so far I have this:

QUESTION
I have a spatial database with thousands of polygons distributed across a country. I want to display those polygons in a mapbox or a leaflet map. However, a simple query that retrieves all of the objects in the database is a massive load for the network and takes a long time, and when it finally loads it takes much of the RAM just holding the geojson object.
I want to solve this more intelligently by querying only the objects that fall within the current map viewport. To this end, I modified my REST service to receive a polygon and using it to filter the queryset (I am using Django REST). This is already working, what I can't figure out is how to obtain the extent of the current viewport.
Does mapbox.js expose this functionality? How can I solve this?
By the way, I am using mapbox.js instead of mapboxgl only because of omnivore support as I am using the well known text format. I am in an early development stage so if this is easier to solve with another library I am open to considering it.
...ANSWER
Answered 2018-Feb-07 at 09:10As you may have noticed, mapbox.js extends Leaflet.
Therefore you should be able to use the map.getBounds()
method to retrieve the extent of the current viewport.
Returns the geographical bounds visible in the current map view
Typically you would listen to the "moveend"
event and perform your query.
Fired when the center of the map stops changing (e.g. user stopped dragging the map).
