Request parameters

Parameter	Description
ID (required)	Specifies the ID of a graphic. Type: string
geometry (optional)	The position and geometry type of graphic. It defines the JSON formats of the geometry and spatial reference objects. Support point and polyline geometry. Point parameters: type The geometry type. Possible values: "point" Type: string x x-coordinate measured along the east–west axis. Type: double y y-coordinate measured along the north–south axis. Type: double latitude The latitude of the point. Type: double longitude The longitude of the point. Type: double spatialReference You can define the spatial reference using a well-known ID (WKID). For a list of valid WKID values, see Coordinate systems and transformations. Type: string JSON syntax: {     "type": <type>,     "x": <x>,     "y": <y>,     "spatialReference": {         <spatialReference>     } } Polyline parameters: type The geometry type. Possible values: "polyline" Type: string paths An array of paths, or line segments, that make up the polyline. Only for polyline type geometry. Type: number[][][] spatialReference You can define the spatial reference using a well-known ID (WKID). For a list of valid WKID values, see Coordinate systems and transformations. Type: string JSON syntax: { "type":<type>, "paths": [ [<x11>, <y11>, <z11>], ..., [<x1N>,<y1N>, <z1N>] ], "spatialReference":{ <spatialReference> } } Polygon parameters: type The geometry type. The first vertex of each ring should always be the same as the last vertex. Possible values: "polygon" Type: string rings An array of rings. Type: number[][][] spatialReference You can define the spatial reference using a well-known ID (WKID). For a list of valid WKID values, see Coordinate systems and transformations. Type: string JSON syntax: { "type":<type>, "rings": [ [<x11>, <y11>, <z11>], …, [<x1N>, <y1N>, <z1N>] ], "spatialReference":{ <spatialReference> } }
symbol (optional)	The symbol for the graphic. Choosing a symbol for a graphic depends on the geometry type of the graphic. Type: double type The symbol type. Possible Values: "picture-marker"| "simple-line"| "simple-fill" Type: string url Specifies the URL or path of a PictureMarkerSymbol. Only for PictureMarkerSymbol. Type: string width The width of the line symbol. Type: number height The height of the image in points. Only for PictureMarkerSymbol. Type: number angle The angle of the marker relative to the screen in degrees. Only for PictureMarkerSymbol. Type: number xoffset The offset on the x-axis in points. Only for PictureMarkerSymbol. Type: number color The color of the symbol. Type: color

注：

At least one of the geometry and symbol parameters is needed to update the graphic.

Example usage

A sample input for updating a point graphic in ArcGIS Earth:

{
    "id":"point-picture-marker-graphic",
    "geometry":{
        "type":"point",
        "x":-100,
        "y":40
    },
    "symbol":{
        "type":"picture-marker",
        "url":"https://static.arcgis.com/images/Symbols/Shapes/BlackStarLargeB.png",
        "width":"128px",
        "height":"128px",
        "angle":0,
        "xoffset":"10px",
        "yoffset":"10px"
    }
}

A sample input for updating a line graphic in ArcGIS Earth:

{
    "id":"polyline-simple-line-graphic",
    "geometry":{
        "type":"polyline",
        "paths":[
            [
                -118,
                34
            ],
            [
                -100,
                40
            ],
            [
                -82,
                34
            ]
        ]
    },
    "symbol":{
        "type":"simple-line",
        "color":"#000000",
        "width":"24px"
    }
}
