Leaflet map United States and fitBounds

由 空扰寡人 提交于 2020-12-15 05:39:06
问题 I've created a function which adds a few layers to my Leaflet map on page load. Afterwards, I want it to center the view based up on these layers. let layerGroup = L.featureGroup(); ... // add multiple layers layerGroup.addLayer(L.geoJson(feature)) ... leafletMap.addLayer(layerGroup); leafletMap.fitBounds(layerGroup.getBounds()); It currently works as intended, and the map zooms in in order to fit the bounds. However, when the United States is one of these layers, the map completely zooms out

This is my code: <template> <body> <div> <li v-for="(message, index) in messageList" :item="message" :key="index"> {{ message }} </li> </div> <l-map class=

Display layers at certain zoom levels in R Leaflet

由 橙三吉。 提交于 2020-12-11 01:03:15
问题 I am working on an interactive map with the R package "leaflet". I would like to change automatically the visible layers depending on the zoom level. For example, I would like to have a polygon layer disappearing when zooming in, replaced by a points layer. Something like this : https://tree-map.nycgovparks.org/ I've been trying many different tricks and exploring in details the help from the "leaflet" and "leaflet.extras" packages, but could not find anything doing that. I also found
