Query Features for featurelayer returns wrong Y coordinate

RubenMensink

Hello everyone

The function queryFeatures() for the class FeatureLayer returns the wrong geometry, specifically the Y coordinate. 

I am running ArcGIS Javascript Api 4.21 and I am sending my query to an on-prem ArcGIS Server running version 10.8.1.

My query is the following

 

public query(): void {
    let pr_t = this.baseUrl+"/FeatureServer/25";

    let layer = new FeatureLayer({
      url: pr_t,
      spatialReference: {wkid: 28992},
      hasZ: true,
      hasM: true,
      geometryType: "point",
    });

    let query = layer.createQuery();
    query.where = ""; // Return all features
    query.returnZ = true;
    query.returnM = true;
    query.returnGeometry = true;

    layer.queryFeatures(query).then(res => {
      console.log("Attributes: ");
      console.log(res.features[0].attributes);
      console.log("Geometry: ");
      console.log(res.features[0].geometry);
    });
  };

 

The result of this query is the following: 

 

Geometry: 
p {__accessor__: g, initialize: ƒ, destroy: ƒ}
destroy: ƒ value()
initialize: ƒ value()
__accessor__: g {host: p, properties: Map(12), ctorArgs: null, destroyed: false, lifecycle: 2, …}
cache: (...)
extent: (...)
hasM: (...)
hasZ: (...)
latitude: (...)
longitude: (...)
m: (...)
spatialReference: (...)
type: (...)
x: 116004.48999999464
y: -67192480.85930108
z: 0.5829999999987194
constructed: (...)
destroyed: (...)
initialized: (...)
[[Prototype]]: m

 

 

The X and Z coordinates are correct, whereas the Y coordinate is not. The expected Y coordinate is 494602.43599999.

The extent of the feature server for this feature is the following:

 

Extent:
XMin: 30316.35599999875
YMin: 305022.16099999845
XMax: 285730.71599999815
YMax: 608180.932
Spatial Reference: 28992  (28992)

 

 

If I query this exact same feature with the ArcGIS rest interface I get the following result (various attributes are omitted):

 

"attributes": {
    "OBJECTID": 1,
   },
   "geometry": {
    "x": 116004.48999999836,
    "y": 494602.43600000069,
    "z": 0.58299999999871943
   }

 

which is the correct result. 

I have afterwards manually inserted geometries with various Y coordinates. If insert a Y coordinate greater than 410000, then I get a negative value similar to -67192480.85930108. It seems that when the Y coordinate gets larger than 410000 a 1-1 mapping occurs, producing a negative value. 

The function that 'gets' my correct Y coordinate is the following:  - x – 66697878.423301

Inserting the incorrect Y coordinate (-67192480.85930108), into the equation, produces this:

494602.43599999 = - (-67192480.85930108) – 66697878.423301

I have not been able to reproduce the negative numbers for X and Z value coordinates, only Y coordinates. 

I do not know a lot about GIS, therefore I assume something is wrong in the configuration of the FeatureLayer or perhaps the Extent of the ArcGIS Server is incorrect. I certainly do not know, but I hope someone in this community does.

Thank you.

I have spoken to a colleague of mine, and he mentioned that PBF has only recently been introduced, and that queryFeatures() uses that instead of json.

My colleague suggested I use an interceptor to force all queries to use json format, instead of PBF. With this I get correct queries. However, this still means that there is a bug with PBF, most likely an overflow of some kind, since there exists a 1-1 mapping.

Does anyone know where to submit such a bug report?
