Default CRS is removed during serialization
Just noticed that during serialization if a default CRS is specified it is removed.
Looking through the spec https://tools.ietf.org/html/rfc7946#section-4 it doesn't mention removal of it, it just specifies the default.
Any comments welcome on this
GeoJson is not usable from Windows Phone 8.1
Wp8.1 cert kit reports the following issues with your project
◦This API is not supported for this application type - Api=System.Type.op_Equality(System.Type,System.Type). Module=MSCORLIB, PUBLICKEYTOKEN=B77A5C561934E089. File=GeoJSON.Net.dll.

I think the project should be transformed to a PCL lib.
Error setting value to CRS on featurecollection
Not sure if it's a bug, something not implemented or just me being stupid but i'm getting an error when deserializing a geojson. I've used geojson.net to process about 20 wfs services but this one is a little different.
the url is : CLICK
Only one difference in the 20 other services and this one and that is the CRS part.
Working:
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:EPSG::31370" } }
Not working:
"crs": { "type": "EPSG", "properties": { "code": "31370" } }
When I do a couple of string replacements, it works so i'm assuming it has something to do with geojson.net and not the service.
A couple of string replacements solve the problem but that's not really the way to go, i think 😉

How to
Hi,
How I use it? Im trying to deserialize it bur JsonConvert.DeserializeObject always give me errors
Add Feature<T> for strongly typed (de)serialization of Feature.Properties
Feature should be added such that properties can be defined by a model. There should be some support for a strongly typed version of properties. The current dictionary representation from an object breaks the use of JsonPropertyAttribute. Of course the reflection could be rewritten using GetCustomAttributes, but it would be more robust to simply use existing mechanisms.
nuget
you've got the nuget spec file but I dont' see your package in the feed. Did you add it?
Can't parse LineString
Trying to parse the json below, errors with "Value cannot be null."
{ "type": "LineString","coordinates": [ [-81.586856, 41.102725], [-81.586856, 41.102725] ]}
Trying to parse the above string with:
JsonConvert.DeserializeObject<GeoJSON.Net.Geometry.LineString>(lineString, new GeoJSON.Net.Converters.LineStringConverter());
Geographic position removed but another project depends on it.
https://github.com/gksource/GeoJSON.Net.Contrib.EF
depends on GeographicPosition do function .... can someone comment on the removal and how the other project should change to work with this change ??
what object replaces it ? why was it removed ?
i just started to see if i can use this project , i have ef models that expose the ef dbGeography type and the other project converts them to work with your code, or it used to...
cannot check null feature
I had some code that just made sure that no one passed a null object as a feature, just something like:
private void DoSomethingWithFeature(GeoJSON.Net.Feature.Feature f)
{
if (f !=null).....
}
Since the update from 1.0.62 to 1.1.63, this value errors out with a null exception every time, regardless if f is actually null or not. Is there a different way i should be checking this parameter?
Coordinate Order
Hi,
working on a fork of your project I noticed that the order you're using in your GeographicPosition class is following:
Latitude, Longitude, Altitude
However the documentation requires the following order:
Point coordinates are in x, y order (easting, northing for projected coordinates, longitude, latitude for geographic coordinates):
And:
A position is represented by an array of numbers. There must be at least two elements, and may be more. The order of elements must follow x, y, z order (easting, northing, altitude for coordinates in a projected coordinate reference system, or longitude, latitude, altitude for coordinates in a geographic coordinate reference system).
http://geojson.org/geojson-spec.html
Is your order wrong or am I?
Cheers,
Fred
Feature.Equals ignores id and properties
The equality comparison methods of the Feature class ignore the Id and Properties properties, resulting in e.g. two features with different Id being equal if the geometries are the same.
Since there is a unit test explicitly covering this behavior, I assume it is by design, but I don't understand the rationale behind; for me, it seems very counter-intuitiive and potential source of hard to trackdown bugs. Can somebody give me a clue?
NuGet License points to 404 (.md missing)
No Json.NET version in the nuspec
The GeoJSON.Net nuspec doesn't include any version information about the version of Json.NET it depends on. This is important, given the ubiquity of Json.NET, and therefore the likelihood of multiple (and therefore, possibly conflicting) transitive dependencies. You should use the minimum version of Json.NET that works.
CRS type issue
Hi, we are having an issue with GeoJSON.net and openlayers 3. The problem is that GeoJSON.Net provides CRS.types with upper-case first letter (i.e. "Name") when openlayers is expecting a lowercase string "name" and throws an CRS.type invalid exception. And the GeoJSON spec says - " the value of its "type" member must be the string "name"/"link" ". I guess the keyword here is "must" and the same issue might be applicable when working with other libraries as well.
Properties object on Geojson
I'd like to put together a pull request to expose out the properties objects, like in the example here http://geojson.org/geojson-spec.html#examples, on the geojson objects I'm deserialising. Given the flexibility of the spec around properties I'd like to pull them in as a JObject which can be access.
Any objections to me putting together this PR?
Porting the library to dnxcore50
Have anyone made an attempt to port the library to CoreCLR/dnxcore50?
I'm building an ASP.NET 5/ASP.NET Core project and would like to use this library. I'd might have a stab at porting it. Opening this issue to discuss if anyone have attempted it so far.
Respect the formatting of the serializer when writing json for MultiPolygon
The current implementation when writing the json for a MultiPolygon uses the default .ToString() method on a JArray which will write json with indented formatting. This causes problems in specific cases where the resulting json must have no formatting applied e.g. when using GeoJSON.NET in conjunction with Elasticsearch's geo_shape type, the Elasticsearch Bulk API uses newline (\n) characters to delimit the actions within the bulk request and the current formatting for a MultiPolygon causes exceptions similar to:
Unexpected end-of-input: expected close marker for ARRAY (from [Source: [B@5ee6d620; line: 1, column: 2])
at [Source: [B@5ee6d620; line: 2, column: 238]
I can send a pull request with a fix
The example throws a NotImplementedException
Provide a test case for the example at
https://en.wikipedia.org/wiki/GeoJSON
to demonstrate feature completeness.
GeographicPosition private setters prevents Deserialization
I was trying to deserialize (with Newtonsoft's JsonConvert) a GeographicPosition object which I recieved from my server unsuccessfully.
I even tried something much more simple, creating a new GeographicPosition object, serializing and deserializing it - something which also "failed", the GeographicPosition object constructed with values (1,2,3), serialized into a correct json object and got deserialized into a GeographicPosition (0,0,0).
After some research I noticed that GeographicPosition class is making use of private setters which were the ones that prevented the correct deserialization, removing them solved the issue.
So, my questions are :
- Why GeographicPosition is using private setters ? What's the benefit ?
- Do I expose myself to any kind of vulnerabilities by setting them as non-private methods ?
- Are there any alternative methods ? good practices ?
Thank you.
In .Net4.0 will cause some problem
What is my mistake in this case?
I have a Web API that have a request model contain a property like this:
public GeoJSON.Net.Geometry.Point Location { get; set; }
I send the value for this property like this:
Location:{ type:"Point", coordinates: [100.0, 120.0]}
but my model is ModelState.IsValid is false.
Thanks for your advises.
Setting to disable camelCase serialisation on feature properties names.
Hi
Great software! My apologies if this is a duplicate issue.
I have the following situation:
I am using your library to pull data out of a database and serve it to a client. However, the client is expecting the feature property names to be the same as those in the database (case-sensitive) e.g. Name, Area, Region.
Is it possible to place a setting on the serialiser to ignore case for property names only?

Nuget version is not updated
When I use Nuget package of GeoJSON.NET for deserializing of FeatureCollection it just throws Not Implemented exception. I've downloaded project, build it and add dll and it works fine, so it looks like you should update the nuget package with the latest fixes.
No types implement ICRSObject

[Question] Why are Coordinates in LineString (and other classes) read-only?
Hi there,
first of all thanks for this great library.
I have a use case where I want to replace the coordinates of a LineString (because they were simplified using https://github.com/imshz/simplify-net). To do this i create a new LineString object and overwrite the existing one in the Coordinates object above.
This doesn't work, because I don't have a setter. Is there a reason this was done the way it is?
(To solve my issue I imported the GeoJSON.Net project and added setters.)
Looping coördinates
I'm deserializing a Json file with GeoJSON.net, which works fine in this way:
var feature = JsonConvert.DeserializeObject<FeatureCollection>(text);
But I can't find how to loop this deserialized 'thing' to get the coordinates (lat/lon) of each multilinestring...
Can someone help me?
Thanks!
Cant binary serialize parent objects containing feature (or likely other objects)
I would like to use the feature object and pass it to another program that would serialize to json. But whilst i would previously serialize the parent object to binary while passing, now i cant.
Is it possible to just add the [Serializable] attribute where needed?
Thanks :)
GeographicPosition: order of longitude, latitude
Why the decision to supply latitude and longitude to the GeographicPosition constructor in the opposite order of the GeoJSON spec? This makes it rather unintuitive, especially when using coordinates in anything other than 4326.
From https://tools.ietf.org/html/rfc7946#section-3.1.1:
"A position is an array of numbers. There MUST be two or more elements. The first two elements are longitude and latitude, or easting and northing, precisely in that order and using decimal numbers. Altitude or elevation MAY be included as an optional third element."
Maybe this could be corrected in the new Position class?

Duplicate class MultiPointConverter.cs
Hi,
I am not sure if that's a big issue but I noticed that there are two MultiPointConverter classes.
One in GeoJSON.Net.Converters and one in GeoJSON.Net.Geometry.
Can be a little confusing when reading quickly the library's contents.
Regards,
GeoJson Version 1.1.64 - Method not found - GeoJson.Net.Geometry.Polygon.get_Coordinates()
I formally used version 0.1.47 and it worked well for me when I try to get coordinates of a polygon, I have just updated to the above version, but gives an error when I try to access the coordinates of a polygon.
Additional information: Method not found: 'System.Collections.Generic.List`1<GeoJSON.Net.Geometry.LineString> GeoJSON.Net.Geometry.Polygon.get_Coordinates()'.

Feature equality problem
Hi,
Feature inherits the Equals implementation from GeoJSONObject. The Equals method returns true if both compared object have the property BoundingBox set to null.
One problem I encountered because of this it that collection.Features.IndexOf(myFeature) will always return 0, regardless of the actual index of the item in the list (given that all bboxes are null).
One workaround is to use ReferenceEquals instead: collection.Features.FinIndex(x => object.ReferenceEquals(x, myFeature))
Thanks for this lib!
geoJson and web api
Hi,
i'm posting a geoJSON object to a web api method, with this signature
[HttpPost]
public GeoJSON.Net.Feature.Feature Post(GeoJSON.Net.GeoJSONObject obj)
but unfortunately there's no way to get obj deserialized from json.
What i'm doing wrong? is web api supported ?
DbGeometry + PolygonConverter = WellKnownText
Hi, I'm storing my polygon on MS SQL Server with EntityFramework's DbGeometry property. When I use the PolygonConverter I'm still getting the WKT format of the data, no the GeoJson.
[JsonConverter(typeof (PolygonConverter))]
public DbGeometry Coordenadas { get; set; }console.log(data.Options[0].Coordenadas);
Do I need to change my data type or create my own fork of this library?
LineString.IsClosed() is incorrectly attempting to cast Positions.
Since the constructor of LineString (on line 32) will accept the IPosition object to create the collections of coordinates
public LineString(IEnumerable<IPosition> coordinates)
any function that tests the position collection for "correctness" such as .IsClosed() should test those positions using the acceptable Interface.
public bool IsClosed()
{
var firstCoordinate = Coordinates[0] as Position;
if (firstCoordinate != null)
{
var lastCoordinate = Coordinates[Coordinates.Count - 1] as Position;
return firstCoordinate.Latitude == lastCoordinate.Latitude
&& firstCoordinate.Longitude == lastCoordinate.Longitude
&& firstCoordinate.Altitude == lastCoordinate.Altitude;
}
return Coordinates[0].Equals(Coordinates[Coordinates.Count - 1]);
}
Array
I have an array of GeoJson Points and it seems invalid at http://geojsonlint.com/
List<Point> ar = new List<Point>();
foreach(DataRow dr in dt.Rows)
{
ar.Add((Point)MsSqlSpatialConvert.ToGeoJSONGeometry((SqlGeography)dr["SsLoc"]));
}
var serializer = new JsonSerializer();
serializer.Serialize(Response.Output, ar.ToArray());
Perhaps the serializer should serialize arrays to GeometryCollection or maybe FeatureCollection
http://geojson.org/geojson-spec.html#geometry-collection
What are your thoughts? or what am I doing wrong? Looking forward to your response.
JsonConvert.DeserializeObject<FeatureCollection>() doesn't load each feature's properties value
Hi
Thank you for great product, I start to use this in my new project.
https://github.com/tilemapjp/Turf.Sharp
I found one bug:
JsonConvert.DeserializeObject<FeatureCollection>("...") doesn't load each feature's properties value.
All features have 0 length properties.
Please see attached zip.
It includes two geojson's, one is Points.geojson, FeatureCollection of Point features.
The other is Point.geojson, one Point feature subset of Points.geojson.
If I load Point.geojson by JsonConvert.DeserializeObject<Feature>(), it is successful to load with 3 length properties.
But if I load Points.geojson by JsonConvert.DeserializeObject<FeatureCollection>(), the properties values of each features are 0 length.
Regards,
Be able to deserialize to IGeoJSONObject object
The library should be able to create an interface of IGeoJSONObject type inferring it's real type from json payload!
Point type results in invalid GeoJson when using DefaultValueHandling.Ignore on server API code
If you use the GeoJson library in Azure API app and you use the following code in WebApiConfig to reduce the amount of Json returned by web API:
config.Formatters.JsonFormatter.SerializerSettings.DefaultValueHandling = DefaultValueHandling.Ignore;
Then the Type is not returned for a Point, when the type is "Point" (is default value for GeoJSONObjectType) resulting in an invalid GeoJson format.
You can solve this by using " DefaultValueHandling = DefaultValueHandling.Include)" in GeoJSONObject.cs
[JsonProperty(PropertyName = "type", Required = Required.Always, DefaultValueHandling = DefaultValueHandling.Include)]
[JsonConverter(typeof(StringEnumConverter))]
public GeoJSONObjectType Type { get; internal set; }
You can test this by adapting the unit tests and addding the " new JsonSerializerSettings { DefaultValueHandling = DefaultValueHandling.Ignore }", example:
public void Can_Serialize_With_Lat_Lon_Alt()
{
var point = new Point(new GeographicPosition(53.2455662, 90.65464646, 200.4567));
var expectedJson = "{\"coordinates\":[90.65464646,53.2455662,200.4567],\"type\":\"Point\"}";
var actualJson = JsonConvert.SerializeObject(point, new JsonSerializerSettings { DefaultValueHandling = DefaultValueHandling.Ignore });
JsonAssert.AreEqual(expectedJson, actualJson);
}
CRS and BoundingBoxes, Required.AllowNull
When I'm trying to deserialize GeoJSON that I work with I got the exception regarding crs property. It occurs because that geoJSON lacks properties crs and bbox, and as I can see from the specification of GeoJSON that properties are not required. That two properties have attribute JsonProperty(Required = Required.AllowNull), which means that they are required but they could be empty. Would it make sense to change to Required.Default, which will make the properties not required?
Reintroduce support for Silverlight
Hi,
I noticed you moved from Profile344 to Profile259 back in January. A major side-effect of this is that the PCL can no longer be used by Silverlight projects.
How would you feel about reinstating Profile344? I don't think its a big job - mostly just avoiding a few of the newer reflection APIs. I can put together a PR, but I thought I'd just check in first in case there are other reasons why this wouldn't be a good idea.
Cheers,
Peter.
