Hillshade renderer

This sample demonstrates how to use hillshade renderer on a raster

How to use the sample

Tap on the wrench button in the Action Bar to change the settings for the HillshadeRenderer. The sample allows you to change the Altitude, Azimuth and Slope type. You can tap on the Render button to update the raster.

How it works

The sample uses the HillshadeRenderer class to render new hillshades. The parameters provided by the user are passed to HillshadeRender at instantiation: new HillshadeRenderer(mAltitude, mAzimuth, mZFactor, mSlopeType, mPixelSizeFactor, mPixelSizePower, mOutputBitDepth); which returns a RasterRenderer. The RasterRenderer is then added to the RasterLayer.

Provision your device

1. Download the srtm-hillshade.zip data from ArcGIS Online.

2. Extract the contents of the downloaded zip file to disk.

3. Create an ArcGIS/samples/raster folder on your device. You can use the Android Debug Bridge (adb) tool found in /platform-tools.

4. Open up a command prompt and execute the adb shell command to start a remote shell on your target device.

5. Navigate to your sdcard directory, e.g. cd /sdcard/.

6. Create the ArcGIS/samples directory, mkdir ArcGIS/samples/raster.

7. You should now have the following directory on your target device, /sdcard/ArcGIS/samples/raster. We will copy the contents of the downloaded data into this directory. Note: Directory may be slightly different on your device.

8. Exit the shell with the, exit command.

9. While still in your command prompt, navigate to the root folder where you extracted the contents of the data from step 1 and execute the following command:

   • adb push srtm-hillshade/. /sdcard/ArcGIS/samples/raster
