kandi X-RAY | basemaps Summary
basemaps is a lightweight R package to download and cache spatial basemaps from open sources such as OpenStreetMap, Carto, Mapbox and others. Retrieved basemaps are translated into and returned as classes of choice, such as raster, stars, ggplot, mapview or magick. The package aims to ease the use of basemaps in different contexts by providing a function interface as minimalist as possible.

QUESTION
I had the existing code which already built with located control and auto update lat/long in value web form(see attached) Now I want to add a draggable maker when my location is detected and auto update the lat/long when maker pin point changed focus on located control function. My search control function work as expected, it was using markerz as maker.
Here was my existing code:

I had the control located css & js ready, but I can't figure it out. I was plan to make it when the located button is pressed, it will located me to the current direction with marker and auto fill lat & long in my web form(As attached).
Below was my existing code for search control. Function auto fill & marker lat/long when search address was found.

QUESTION
I've been incorporating the MarketCluster and the associated FeatureGroup.SubGroup plug ins from Leaflet to add additional functionality to my generated QGIS2web map.
Part of my requirements is toggleable layers and where MarkerCluster works well when I had categorized layers from QGIS that were automatically clustered with separate layers this is no longer the case. To my understanding I needed either MarkerCluster.LayerSupport or FeatureGroup.SubGroup plugins to handle the additional layers and still provide clustering.
I've incorporated the CSS from MarkerCluster, JS from MarkerCluster and SubGroup, as well as called it in the map and in the respective places but the icons aren't actually clustering - image below.
The bottom 3 layers are all under the parent group mcg and all have been added to the map and called under the plugin so I'm not too sure why they are not clustering at small scales?
Var map code:

Answered 2022-Feb-24 at 22:39I have now got it working by using MarkerCluster.LayerSupport
and by adding it to both var map and checking it in - maybe wrong plugin usage but likely my human error.

QUESTION
So I'm in the process of making a web map of previous projects. My experience with JavaScript and general web programming languages are limited and outdated (apparently OnClick is deprecated?)
Either way, I'm using QGIS2Web alongside Leaflet to produce this map and then had planned to further fine tune it through the source.
All has been well so far but now I am trying to add an event that occurs on click/on layer add (but not of every layer only specific region layers) which would then pan the map to the centroid of that region.
I started by first defining the function

Then do just that, and don't overcomplicate things by trying to find workarounds.
All leaflet layers are event targets, and fire add

events, as documented, as well as on
/off
methods for attaching/detaching event handlers.
So if you have a layer in a variable layer_NorthEastnoinvert_7

QUESTION
I am a total javascript/leaflet/ag-grid newbie, so please bear with me.
I am creating a website that allows users to query (add/remove) spatial points on a leaflet map based on selecting rows from ag-grid. I have no understanding/experience with React or Angular, so I am using vanilla javascript. Leaflet is used to display the data spatially.
I have spatial data that has GPS coordinates that are parent records. Each parent they have multiple children.
Spatial dataThe spatial data is an external file I read into my HTML file. It looks like this:
...ANSWER
Answered 2022-Feb-15 at 19:05So once onSelectionChanged
is called with the filtered rows - what script do you need to pass it to?
I assume you want to link the table with the leaflet map. If so, you need to
- obtain a reference to the map object (see Leaflet docs)
- create a GeoJSON layer based on the filtered Geometries and add it to the map.
If the filtering in the table and thus the leaflet layer data update happens multiple times, you need to remove the existing layer and add a new one, as far as I know. Check this post.

There is a Main component, which has 4 separate components. It is necessary that these components are not visible before the user does not use the search.
The first component is responsible for displaying the weather graph, and the second for displaying the map. I do not know how to hide these two components specifically.

QUESTION
I'm currently creating a vue3 cli app that uses vue-leaflet (the vue3 compatible version)
Everything works great on my local dev environment but once my app is built the map doesn't load, even when I resize like this thread explains well.
I tried using the leafletObject.invalidateSize()
method but nothing changed.
My map is a component called using a v-if on first call (switch between a list view and the map) and a v-show once it has been initialized

Answered 2022-Jan-03 at 12:00Rather looks like the Leaflet CSS is incorrectly loaded in your production bundle: tiles are scrambled up, no zoom and attribution controls.
QUESTION
if I add "baseMaps" to my layer control, "huts" is actually a checkbox. But I only have one basemap, so I dont need that in my layer controls. But I still wanted to be able tu turn off my "huts" overlay. But as soon as I remove "baseMaps" "huts" becomes a radio button and cannot be turned off. Is there a way?
...ANSWER
Answered 2021-Dec-16 at 18:06The 1st argument of L.control.layers
populates the "base maps" (with radio button), while its 2nd argument populates "overlays" (with checkboxes).
If you only want overlays, you can simply pass null
to the 1st argument:
QUESTION
I have two leaflet maps which are loaded with geojson on the basis of a search button click. This shows some polygons with a style opacity 0.3 so you can see the street names under the polygons.
It works great except that any additional searches and loading of polygons starts to change the opacity of the polygon, making it more solid so you cant read the names of the streets under the polygon.
I try clearing the geojson layer before adding to the map, but the issue persists.
I have created a rough code pen of the issue here: https://codepen.io/joomkit/pen/xxXgLPJ?editors=1111
Essentially just click the search button to load the layer no need to fill the listener runs a function and gets static data.
I have tried various methods to remove layer. A second click on the search is meant to clear the layer and load a new one. In the example it's just reloading the original data but the opacity is clearly demonstrated.
Main code is also below.
...ANSWER
Answered 2021-Dec-16 at 10:06You need to keep the geojson layer in a global variable and remove it before over writing with the new layer data.

Install basemaps
All available map services and map types can be printed using get_maptypes(). The basemap() function and its class-specific aliases facilitate (down)loading a basemap and returning it as a class of choice. Map preferences that should be used during a session can be set as defaults using set_defaults().
