[@masterchief9148]

Incredibly usefull ! Thanks !

[@geodev]

Glad it was helpful for you❤️

[@masterchief9148]

@@geodev Yes ! But do you think it's possible to add an input on the page, search a property name of the GeoJSON and on a submet automaticly zoom on this point on the map ?

[@Peterincan]

This is fantastic! Thanks very much. One problem I ran into. For creating the popups I followed the steps in your video but the popup always shows the information for the last feature in the geoJSON file. Any ideas?

[@geodev]

Did you check the `onEachFeature` function as shown in the video? or you can check the Final version of github file given in the video description.

[@pudicaoutdoors5352]

I'm having the same issue, I thought the onEachFeature would take care of it, but it does not or I'm missing something. Are we missing a syntax that will grab the attribute for it's relative point?

[@geodev]

@@pudicaoutdoors5352 I think it should work with the onEachFeature function if you setup it correctly. For the clear understanding about onEachFeature, visit this leafletjs official documentationleafletjs.com/examples/geojson/

[@pudicaoutdoors5352]

@@geodev I'm new to javascript, but my code is almost exactly the same as yours. I thought the onEachFeature would remove the need for a for loop or an update option that doesn't seem to be the case. Each marker has a popup but they only display content for the last feature. Ahh nvm I just had parentheses misplaced

[@hamsdecor1246]

Thank you

[@geodev]

You are welcome.

[@haybeedenzebee]

Hi, I have a slight issue with the pointToLayer, more specifically, it doesn't take in account the style of the markers defined in the constant geojsonMarkerOptions, is there any way to fix the problem, please?

[@haybeedenzebee]

Replying to myself : I found a way to avoid the issue :D

[@MrTizinator]

Is it possible that all the clusters are expanded (spiderfied) from a certain zoom level on? Like everything past zoomLevel 15 or higher every cluster is expanded and every marker on the map is shown

[@geodev]

I am not sure. Since I am using the plugin, there is not much flexibility.

[@SergioHernandez-lb1hs]

Hello, I really like your videos, could you help me with this? how can I assign, to two layers of clusters that feed from the css markercluster.css and markercluster.default.css, so that each cluster has a different type of coloring and if possible you can change the circle of the cluster by some kind of icon?

[@geodev]

Hi, I haven't explored all the possibilities of the marker cluster function, but you can have a look to their official documentation here: github.com/Leaflet/Leaflet.markercluster

[@snowblind9290]

Thank you, this was a big help but I'm afraid there's a bug in your code. When a marker is clicked it displays the same information no matter which marker it is. I forked your project (the one you're showcasing on this video) and it suffers from the exact same problem. I noticed that you only clicked on one marker which showed SL47 but every marker is showing this exact data as well. It's possible that there is an uncaught bug in the github for MarkerCluster. I'm still trying to solve this myself but any assistance is greatly appreciated.

[@geodev]

Thank you for addressing this bug. I have update the code in github: github.com/iamtekson/Leaflet-Basic/blob/master/marker-cluster/index.html, please find the correct bug free version.

[@snowblind9290]

@@geodev Thank you!

[@ryukazusaviestyan4060]

Can we set the parent and the child of marker cluster manually? If it's possible, what should we do? Thank you.

[@geodev]

I think it is possible. You might need to give the different style for parent and the child markers. Here is the small demo: jsfiddle.net/cxZRM/92/

[@Life_With_Nature_]

do you have a video to search marker location by id or name or something?

[@geodev]

I think it is possible with this plugin: github.com/stefanocudini/leaflet-search

[@Superdooperhero]

Can you also show how to move the markers every second with a streaming GeoJSON and 10000 points as well as the marker groupings.

[@geodev]

Sorry, I don't understand what do you want?

[@weslleymorais]

Congratulations on the videos, I followed most of them. How do I make clusters using marked points with the following command lines: var Point1 = L.marker([0.833005, -60.436509], var Point2 = L.marker([0.833032, -60.434503], Would it be possible to make a video teaching the procedures? I didn't find any video explaining this. Thank you.

[@acpunetha]

Can we take the data from api and display the marker make a video

[@varunmurugan2349]

if marker cluster work for linestrings what we have to do for large linestring geojson data

[@geodev]

I think it is possible. Here is some reference about this functionality: gis.stackexchange.com/a/197982/138203

@@geodev yes i tried that still hangs for me...i even tried geojson-vt package in react-leaflet but it wrks nly for leaflet not for react-leaflet

Very nice! Can you show how to costumize the GeoJson marker icon with a png. file?

[@geodev]

I customize the marker in this video, please have a look for your reference: kzbin.info/www/bejne/bJ6klYWarL-cnsU

your leaflet conent is very helpful for us. keep going good work.i have one question, i have geofence area how could i find if person outside his geofence area using their mobile location. could you guide me i am new in this.

[@geodev]

Hi Danial, The feature that you require can quickly build with the help of turfjs. I think, in your case, you need to use the "pointWithinPolygon" function. If you are new to turfjs, here is the basic exploration of this library: kzbin.info/www/bejne/jpCVfmZnpZqqaK8
