Crop Raster Layers using GIS C# Library

Crop using vector shape

Aspose.GIS API lets you crop a raster layer using vector shape as shown in the code snippet below.

// 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, "geodetic_world.tif")))
using (var warped = layer.Crop(Geometry.FromText("POLYGON ((-160 0, 0 60, 160 0, 0 -160, -160 0))")))
{
    // read and print raster
    var cellSize = warped.CellSize;
    var extent = warped.GetExtent();
    var spatialRefSys = warped.SpatialReferenceSystem;
    var code = spatialRefSys == null ? "'no srs'" : spatialRefSys.EpsgCode.ToString();
    var bounds = warped.Bounds;

    Console.WriteLine($"cellSize: {cellSize}");
    Console.WriteLine($"source extent: {layer.GetExtent()}");
    Console.WriteLine($"target extent: {extent}");
    Console.WriteLine($"spatialRefSys: {code}");
    Console.WriteLine($"bounds: {bounds}");
}
