Overlapping Marker Spiderfier Marker Icon When There are Multiple Markers at Same Location

不问归期 提交于 2019-12-03 13:44:42
Google Maps doesn't provide a way to break apart multiple markers that are at the same location. This can occur with a people or businesses at a multiple residency location such as an apartment building or professional services building. Depending at zoom level it can also occur at shopping malls, etc. The way around that is to "spiderfy" them: when clicking on the first it breaks them out with a line to the location. This is done in Google Earth and George MacKerron wrote a package to do that for Google Maps. ( https://github.com/jawj/OverlappingMarkerSpiderfier ) It can be integrated with

Server Side Google Markers Clustering - Python/Django

旧巷老猫 提交于 2019-12-03 09:55:46
问题 After experimenting with client side approach to clustering large numbers of Google markers I decided that it won't be possible for my project (social network with 28,000+ users). Are there any examples of clustering the coordinates on the server side - preferably in Python/Django? The way I would like this to work is to gradually index the markers based on their proximity (radius) and zoom level. In another words when a new user registers he/she is automatically assigned to a certain 'group'

Get a list of markers in bounds of google map using markerclusterer v3

谁都会走 提交于 2019-12-03 09:16:57
问题 I currently have a google map populated with data from a database. I am using markerclusterer v3 to cluster the markers to make the map load faster. I have scoured the docs and cannot seem to find a way to get a listing of all markers that are in the map bounds. Essentially I am trying to create an external list of the markers addresses in an external div. Currently on page load it appends the whole list of addressees. What I would like to do is have only the markers, and the markers

Clicking on marker cluster wants to open spider with exact same location markers by default

左心房为你撑大大i 提交于 2019-12-03 08:47:46
I was trying to implement MarkerCluster (MS) with Overlapping Marker Cluster (OMS). Everything seems to work just fine. However, I am looking to modify the way OMS is works so that if I click on a cluster that has 2 points under it When I click on any Cluster with 2 points in it with exact same geo location, its opens a marker and when I am clicking on that marker it's opening spider with 2 markers. What I want when I am clicking on the Cluster, straight a way it will open up spider with 2 markers, already spend lot of times but still nothing worked. I already tried many solutions, like 1. I

MarkerClustererPlus: set icon color/url independent of size

寵の児 提交于 2019-12-03 08:06:25
I'm plotting a few hundred thousand points via MarkerClustererPlus, and I want to set groups of cluster icons (colour) based on some exteral property ( not based on number of markers represented). The only way I can think to do this is by creating multiple MarkerClusterer objects and passing in a different options object, but I feel like I'll take a big performance hit doing that. Is there a better way? Given the image above, I'd like 139, 24, and 5 to be yellow and 213, 25, 30, and 2 to be red; and if possible, update their styles/options via setOptions: mc.group[0].setOptions({"url": imgPath

问题 I want to integrate maps in my react-native app, I am using the “react-native-maps” library for that https://github.com/airbnb/react-native-maps I want to use clustering but I am unable to find proper documentations related to that. Please help me to find documentation of how to integrate maps with clustering and also tell which library is best for the implementation of clustering for both platforms, iOS and Android. 回答1: You can use mapbox/supercluster repo, and here's a gist showing how to

How can I find the center of a cluster of data points?

markerClusterer on click zoom

末鹿安然 提交于 2019-12-03 01:16:54
I just added a MarkerClusterer to my google map. It works perfectly fine. I am just wondering if there is any way of adjusting the zoom-in behaviour when the cluster is clicked. I would like to change the zoom level if possible. Is there any way of achieving this? Thanks There has been an update to the MarkerClusterer source code, allowing much easier access to the click event: google.maps.event.addListener(markerCluster, 'clusterclick', function(cluster) { // your code here }); where 'markerCluster' ist the MarkerCluster object. Inside the function you may also access cluster.getCenter();
