从 RasterLayer arcgis js 获取数据（值）

Question

I have mapserver which contains tif files (raster layer).This files contains temperature data. I want to know how to get data from this raster layer. I look a lot of arcgis js api samples,but none of them show how to read data from raster layer.

Answer 1

ArcGIS JS API support WCS (Web Coverage Service), OGC standard, which is supported by every map server including MapServer.

In that way, you will use a WCSLayer , wich has several properties and methods to handle information of bands an pixels.

ArcGIS JS API - WCSLayer

MapServer - WCS

Answer 2

      import * as identify from "@arcgis/core/rest/identify";
      .
      .
      .
        return identify
            .identify(url, params)
            .then(function (response) {
                var results = response.results;
               
                results.map((result, index) => {
...
}

This was solution for me
