PROJECTING WGS1984(102100) GEOMETRY TO WKT

ACHANUMA — Mon, 22 May 2023 19:23:47 GMT

Hi Friends,

I am trying o project certain points in wgs84 (wkid: 102100) to a custom projection (wkt shown below) in a WAB widget (running on jsapi 3.27 ) . FYI, i cannot use a wkid as its a custom projection with modified parameters.

PROJCS["NAD_1983_UTM_Zone_11N",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",1640416.666666667],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",-117.0],PARAMETER["Scale_Factor",0.9996],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Foot_US",0.3048006096012192]]

My Sample Code:

// input SPRS

var inputSRS=new SpatialReference({

wkid:102100

});

// Output SPRS

var outputSrs = new SpatialReference({"wkt": 'PPROJCS["NAD_1983_UTM_Zone_11N",' +

'GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",' +

'SPHEROID["GRS_1980",6378137.0,298.257222101]],' +

'PRIMEM["Greenwich",0.0],' +

'UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],' +

'PARAMETER["False_Easting",1640416.666666667],PARAMETER["False_Northing",0.0],' +

'PARAMETER["Central_Meridian",-117.0],' +

'PARAMETER["Scale_Factor",0.9996],'+

'PARAMETER["Latitude_Of_Origin",0.0],'+

'UNIT["Foot_US",0.3048006096012192"'

});

// Projection logic

projection.load().then(lang.hitch(this,function()

{

var projectedPoints = projection.project(inputPoints, this.outputSrs);

projectedPoints.forEach(function(point) {

console.log(point.x, point.y);

});

}));

I getting the below error msg when the code tried to project the input points. Just wondering of jsapi 3.27 version has a known bug with SPRS that are defined using wkt instead of wkid.

Your help is appreciated.

Seems like you have an issue in the WKT text. The WKT is supported when projecting. For instance, there is two pp here: PPROJCS I removed this and was not able to project it. So I have used this WKT: https://spatialreference.org/ref/epsg/nad83-utm-zone-11n/esriwkt/ and projection happens as expected.

This codepen shows a proof of concept in 4.26. https://codepen.io/U_B_U/pen/RwevmgB?editors=1000
