I am working with ENC files from noaa, specifically S57 format or ".000" to be as specific as possible.
I am trying to render a layer or even the entire thing in a window but have had no luck. Perhaps you could tell me where I am going wrong.
I am pretty sure the error is happening here:
layer = QgsVectorLayer(filename, "DEPARE", "ogr")
I get the error:
ERROR 4: S57 Driver doesn't support update.
from qgis.core import * from qgis.gui import * from PyQt4.QtCore import * from PyQt4 import QtGui app = QtGui.QApplication() QgsApplication.setPrefixPath("C:/OsGeo4w/apps/qgis", True) QgsApplication.initQgis() window = QtGui.QMainWindow() window_frame = QtGui.QFrame(window) window.setCentralWidget(window_frame) frame_layout = QtGui.QGridLayout(window_frame) canvas = QgsMapCanvas() frame_layout.addWidget(canvas) filename = "C:/Users/jacot/Desktop/ENC_ROOT/US1AK90M/US1AK90M.000" layer = QgsVectorLayer(filename, "DEPARE", "ogr") if not layer.isValid(): print "Layer failed to load!" QgsMapLayerRegistry.instance().addMapLayer(layer) canvas_layer = QgsMapCanvasLayer(layer) canvas.setLayerSet([canvas_layer]) canvas.zoomToFullExtent() window.show() app.exec_()
Ultimately I want to save this in a raster format like .tif or .png. Maybe it would be easier to do that first? Could you assist me or point me towards documentation for this as well?
