Work with Raster Layers using GIS C# Library

Working with multi-band raster on GeoTIFF samples

GeoTIFF is one of the most widely used raster formats among GIS Software. Aspose.GIS lets you work with the GeoTIFF raster format.

	// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
	string filesPath = RunExamples.GetDataDir();
	using (var layer = Drivers.GeoTiff.OpenLayer(Path.Combine(filesPath, "raster50x50.tif")))
	{
	// read and print raster
	var cellSize = layer.CellSize;
	var extent = layer.GetExtent();
	var spatialRefSys = layer.SpatialReferenceSystem;
	var code = spatialRefSys == null ? "'no srs'" : spatialRefSys.EpsgCode.ToString();
	var bounds = layer.Bounds;
	var bandCount = layer.BandCount;

	Console.WriteLine($"cellSize: {cellSize}");
	Console.WriteLine($"extent: {extent}");
	Console.WriteLine($"spatialRefSys: {code}");
	Console.WriteLine($"bounds: {bounds}");
	Console.WriteLine($"bandCount: {bandCount}");

	// read and print bands
	for (int i = 0; i < layer.BandCount; i++)
	{
	var dataType = layer.GetBand(i).DataType;
	var hasNoData = !layer.NoDataValues.IsNull();
	var statistics = layer.GetStatistics(i);

	Console.WriteLine();
	Console.WriteLine($"Band: {i}");
	Console.WriteLine($"dataType: {dataType}");
	Console.WriteLine($"statistics: {statistics}");
	Console.WriteLine($"hasNoData: {hasNoData}");
	if (hasNoData)
	Console.WriteLine($"noData: {layer.NoDataValues[i]}");

	}
	}

The EsriAscii format always has only one band.
