Answered 2021-Dec-24 at 08:38I use a similar code to draw a polygon on a basemap and have a similar issue when using Vue3 with leaflet and leaflet-draw. After drawing a polygon, I get a bunch of errors in the console, probably triggered by a mouseover event.
QUESTION
I made a code below for creating shapes with some informations. I can edit thoose informations until my map is open. But after update geojson by "Export features to local file" and page reload, shapes remain unclickable and to correct the informations I have to delete some shapes and recreate them with proper parameters.
Question:
Is it possible to edit the shape's data each time I just open my page? Like I can edit the shapes itself by "Edit layers" button?
...ANSWER
Answered 2022-Jan-23 at 14:45Of course, I did it quickly, so you have to adapt to your own code. I removed L.GeoJSON.AJAX but nothing prevents you from continuing to use it, I advise you not to ;)
QUESTION
I'm trying to load a leaflet map within a div tag.
Sometimes the map tiles are loaded completely. whenever I try to zoom in or zoom out the map, tiles are not loading completely. I tried solutions like importing leaflet CSS styles, tried to call the invalidateSize function whenever the map is zoomed in.
...ANSWER
Answered 2021-Sep-30 at 09:30While trying to reproduce the above issue in fiddle with only Javascript. The map was rendered properly so I came to the conclusion that there is no issue with rendering the map. While debugging I found the div element that contains map has one of its parent elements has a property of text-align: center which caused the map to load tiles not completely. After removing it map was rendered as expected. I hope it may help someone while rendering a map in element(like div) consider the alignment of parent elements which may happen rarely.
QUESTION
I'm trying to make a web app that uses leaflet to display a map, users should be able to draw and edit polygons over the map and they should have the ability to name each polygon they create.
I want to open a popup when a polygon is created that asks for a name and then set it to a property in a geojson feature.
I tried to follow this example Leaflet popup form but I couldn't get it to work with the leaflet draw created event.
Here's what I got.
...ANSWER
Answered 2021-Apr-19 at 08:04Just bind a popup on the created layer and open it once it is created
QUESTION
I am trying to delete a Leaflet.draw layer from my database in firestore. I can easily delete it from the database side, but i struggle with connecting the document name with the layer name.
More specifically, i can't seem to get the id of the layer to be deleted/edited. Once i have that i should be able to connect it to the document id
This is what i got currently:
...ANSWER
Answered 2020-Dec-18 at 11:20propagatedFrom is indeed undefined. It is not provided on the event object
just remove propagatedFrom and use e.layers instead.
QUESTION
I will want to get the coordinates of each corner of a rectangle that the user will draw on a map (leaflet).
The goal is to extract the max/min latitude and the max/min longitude.
Here is the code under which I display my map and I draw my rectangle with Leaflet-Draw :
...ANSWER
Answered 2020-Oct-27 at 07:30Use getCenter() instead of getLatLng()
EDIT: I see the issue you need each corner of the rectangle, getCenter does not solve that
Also I recommend leaflet-geoman for editing instead of leaflet draw. (But thats just my opinion :) )

QUESTION
I've been working on a map component that renders points of results that stream in from search. I have gotten most of it working, until I began passing props in for the return statement. I'm using my own component, not react-leaflet's . I've noticed if I use and render with props.locations.map( ... it works fine. If I reference my map = L.map(...) with and try to render with props, it breaks as soon as it attempts to create the layer and add it to the map.
The component's JS File is as follows:
...ANSWER
Answered 2020-Sep-30 at 20:07So as I mentioned in the comments you should use react'leaflet's Map and use a ref to add any plugin you wish using native leaflet code.
QUESTION
My goal is to add leaflet-draw to my Map. To do this, I've been using L to add control and drawnItem layers to the map upon component mount. The problem seems to be with the TileLayer. If I add it in the rendered div, it only fills 80% of the map leaving the new toolbar looking awful. If I add it in with L.TileLayer, it fills the entire map but leaves the majority of the map un-draggable. I will demonstrate with pictures.
With adding TileLayer in rendered div:
When added upon component mount:
NOTE: The blue area is the area which cannot be interacted with. The only way to manipulate the map is by dragging under the draw toolbar. I will include the div of this in-operable layer:
Finally, it is important to note that if I manually delete this element in the browser dev tools the map works fine. To make this issue more concise, I will remove all leaflet-draw code so that the issue can hopefully be more obvious. I'll now show the code along with the index.html.
...ANSWER
Answered 2020-Sep-23 at 18:08The issue was that I was rendering a map on top of the one I had created in componentDidMount().
I instead used from let map = L.map('mapsearch',).setView([51.505, -0.09], 6); to reference my own. Silly mistake, but really threw me off.
