Type alias: TIFFImageryProviderRenderOptions

Ƭ TIFFImageryProviderRenderOptions: Object

波段计算

• 比如 NDVI 计算

Example

TIFFImageryProvider.fromUrl(YOUR_TIFF_URL, {
  renderOptions: {
    single: {
      colorScale: "rainbow",
      domain: [-1, 1],
      expression: "(b1 - b2) / (b1 + b2)"
    }
  }
});

• 自定义色带

• Example

TIFFImageryProvider.fromUrl(YOUR_TIFF_URL, {
  renderOptions: {
    single: {
      colors: [
        [1, "rgb(154, 206, 127)"],
        [2, "rgb(163, 214, 245)"],
        [3, "rgb(255, 251, 177)"],
        [4, "rgb(193, 114, 97)"],
        [5, "rgb(220, 100, 120)"],
        [6, "rgb(49, 173, 105)"]
      ],
      type: "discrete",
      useRealValue: true // 使用tiff真实值作为色带的控制点
    }
  }
});
