geojsonlint.com | A simple Django app to validate your GeoJSON | Validation library

Currently making a project in Laravel that uses MapboxGLJS. I've currently got a database server that I'm connected to that contains comments which I need to convert to a GeoJSON FeatureCollection that includes the ID and the spacial data. I've seen an example of the code to do this which I'll provide below but when I try to use said code and try to use the addSource Mapbox method it comes back with Error: Input data is not a valid GeoJSON object..

CommentController.php

I am having an issue with Mapbox GL JS v2. I have a geojson dataset that mostly renders correctly in the map, but certain features won't render correctly with the "fill" layer style. The fill doesn't "show" up until you zoom way in and even then it kind of flickers around. I know the geojson is valid (at least according to geojsonlint.com. I have linked to a js fiddle showing the issue with one of the features. I thought at first it might be just related to my implementation, but it still happens when I modified a Mapbox example. Any help would be appreciated!

Thanks!

We are indexing geo-json polygons using the shape data type in Elastic Search. The polygons are provided to us from an external source. When indexing, some of the polygons fail with the following message.

"Unable to Tessellate shape [[12.775555, 61.54487] [12.797356, 61.53186] [12.795639, 61.549286] [12.832375, 61.54536] [12.775555, 61.54487] ]. Possible malformed shape detected."

We believe the issue is related to self-intersecting polygons. The polygons seem to be valid, according to e.g https://geojsonlint.com. Below is an example of a self-intersecting polygon:

I am trying to get navigation directions using mapbox-sdk for react-native from npm package:

"@mapbox/mapbox-sdk": "^0.11.0"

And for rendering the directions returned by mapbox-sdk I am using the below npm package:

"@react-native-mapbox-gl/maps": "^8.1.0-rc.8",

Code I am using for retrieving directions:

I am trying to store some data in geoJSON format as follows.

I'm using MapBox GL JS v1.4.1

Based on the example here: https://docs.mapbox.com/mapbox-gl-js/example/cluster/

I cannot get my cluster count to display.

I have tried replicating the MapBox example directly and also using my own data but whatever I try results in the count not displaying.

This is what I have:

I am trying to render a polygon from a webservice to a mapbox map as a proof of concept.

My webservice gives me the following geojson with some mock data:

I have been struggling trying to get d3.js to render geoJSON data correctly into an SVG. The following JSFiddle shows the problem

http://jsfiddle.net/8zjb3yrq/

You will notice that the result of fiddle produces a white object on a gray background, but it should instead be showing a gray object on a white background. Basically it's showing the desired shape as a hole in the rest of the map. I've been trying to show multiple of these shapes, but they overlay eachother because of this and I only see the last one. I'm pulling data from a geography field in SQL Server, converting it to geoJSON and passing it to this page. Some shapes render correctly, but others do not and I haven't found a pattern yet. I've used http://geojsonlint.com/ and http://geojson.io to validate the geoJSON and they show it correctly.

My javascript code looks like this:

I have several fields in a json file, and I need to determine which of the json-fields are GeoJSON. For example, here is a sample of the data I have:
