How to add markers on map from GeoJSON with points?
I’m trying to add some markers on my map using a geoJson with Points, I’m following the leaflet documentation but it still saying: Error: Invalid GeoJSON object.
How to create a custom icon in GeoJSON?
Here is a section of the code, which is filtering based on an attribute in the geoJSON, but I would also like to give it a custom icon and attributes in the pop-up. To create a custom marker you can create a L.Icon object and for the popup you can use the onEachFeature option.
What are the issues with my Leaflet map?
I am having some issues with two things in a Leaflet map 1) custom marker 2) pulling attributes from a geoJSON file and putting it in the pop-up. I should qualify things, I am really new to Leaflet and web development.

How to use GeoJSON to create a leaflet?
GeoJSON is becoming a very popular data format among many GIS technologies and services — it’s simple, lightweight, straightforward, and Leaflet is quite good at handling it. In this example, you’ll learn how to create and interact with map vectors created from GeoJSON objects.
How are points handled in a GeoJSON layer?
Points are handled differently than polylines and polygons. By default simple markers are drawn for GeoJSON Points. We can alter this by passing a pointToLayer function in a GeoJSON options object when creating the GeoJSON layer. This function is passed a LatLng and should return an instance of ILayer, in this case likely a Marker or CircleMarker.
How are features and featurecollections used in GeoJSON?
Features in GeoJSON contain a Geometry object and additional properties, and a FeatureCollection contains a list of Features. Leaflet supports all of the GeoJSON types above, but Features and FeatureCollections work best as they allow you to describe features with a set of properties.
How to add a GeoJSON layer to a leaflet?

When to use the oneachfeature option in GeoJSON?
onEachFeature. The onEachFeature option is a function that gets called on each feature before adding it to a GeoJSON layer. A common reason to use this option is to attach a popup to features when they are clicked.
Which is the latest version of leaflet.js?
UPDATE: updated leaflet.js to version 1.3.3. The difference with the update is that each layer needs to be initialised using the new key word. Code is updated to reflect the change. Thanks for contributing an answer to Stack Overflow!
