open ecw files offline as base map

[idozoar]

Hi,

I'm new to ArcGIS runtime sdk for java.
I need my app to open my own base map that represented by about 6-7 .ecw files (including of course matching .aux files).
How do I add a layer from .ecw file to JMap?
I  tried:
JMap map = new JMap(); ... String rasterPath = "k5521.ecw"; //the file is in the folder of the project
FileRasterSource rasterSource;

try {

     rasterSource = new FileRasterSource(rasterPath);

     RasterLayer rasterLayer = new RasterLayer(rasterSource);

     map.getLayers().add(rasterLayer);

} catch (IllegalArgumentException iex) {

// handle exception

} catch (FileNotFoundException fe) {

// handle exception

} catch (RuntimeException re) { // handle exception }

and also:

FileRasterSource rasterSource = new FileRasterSource("k5521.ecw");

rasterSource.project(map.getSpatialReference());

RasterLayer rasterLayer = new RasterLayer(rasterSource);

map.getLayers().add(rasterLayer);

what am I doing wrong?

ido zoar​ So it turns out the .ecw is not supported with Java API. You can instead use the approach to add local Raster files to a Local Map service created from a blank mpk. The only drawback there is that for Raster local server doesn't support Renderers.

Below is a small code snippet. You can make modifications as per your requirements

final String workspaceId = ""+count++; // an arbitrary unique string

	// create a local map service and enable dynamic layers
	LocalMapService localMapService = new LocalMapService("C:\\mpk_blank.mpk");

	if(!localMapService.getEnableDynamicLayers()) {
	localMapService.setEnableDynamicLayers(true);
	}

	if(localMapService.getStatus() == LocalServiceStatus.STARTED) {
	localMapService.stop();
	}

	// get dynamic workspaces from service
	WorkspaceInfoSet workspaceInfoSet = localMapService.getDynamicWorkspaces();

	// create a workspace info via the static method according to data type
	// e.g. shapefile folder connection
	WorkspaceInfo workspaceInfo = WorkspaceInfo.CreateShapefileFolderConnection(
	workspaceId, fileDir);
	// also:
	// --> WorkspaceInfo.CreateSDEConnection
	// --> WorkspaceInfo.CreateRasterFolderConnection
	// --> WorkspaceInfo.CreateFileGeoDatabaseConnection

	// set dynamic workspaces for our local map service
	workspaceInfoSet.add(workspaceInfo);
	localMapService.setDynamicWorkspaces(workspaceInfoSet);

	// now start service...
	localMapService.start();

	// set up a local dynamic layer
	final ArcGISDynamicMapServiceLayer localDynamicLayer = new ArcGISDynamicMapServiceLayer(localMapService.getUrlMapService());

	// add the layer to the map
	jMap.getLayers().add(localDynamicLayer);

	localDynamicLayer.addLayerInitializeCompleteListener(new LayerInitializeCompleteListener()
	{
	@Override
	public void layerInitializeComplete(LayerInitializeCompleteEvent arg0)
	{

	DynamicLayerInfoCollection layerInfos = localDynamicLayer.getDynamicLayerInfos();
	DynamicLayerInfo layerInfo = layerInfos.get(0);

	DrawingInfo drawingInfo = new DrawingInfo(simpleRenderer, TRANSPARENCY);
	layerInfo.setDrawingInfo(drawingInfo);

	// Create the data source
	TableDataSource dataSource = new TableDataSource();
	dataSource.setWorkspaceId(workspaceId);
	dataSource.setDataSourceName(fileName);

	// Set the data source
	LayerDataSource layerDataSource = new LayerDataSource();
	layerDataSource.setDataSource(dataSource);
	layerInfo.setLayerSource(layerDataSource);

	localDynamicLayer.refresh();
	}
	});
