I have written a Python script for QGIS 2.14.3 which reads in every .txt file in a folder containing hundreds of .txt files (format: "X Y Z" whitespace-separated)and converts them to ESRI shapefiles.
As a next step I want to generate contour lines for every shapefile. Therefore I have installed the Contour plugin (V.1.4.2) from https://github.com/ccrook/QGIS-Contour-Plugin
How can I call the Plugin from my script?
Can I somehow import my plugin folder to make my installed plugins accessible?
When I look into /homefolder/.qgis2/python/plugins/contour there are five .py files...
Of course I could do the whole workflow by hand with the GUI, but that would take too long.
If somebody needs the script mentioned above (which converts the .txt files to shapefiles), here is the code:
# Defines Input parameters which are displayed in the GUI ##Input_Folder=folder ##Unbuffered_PolygonLayer=vector ##output_Folder=folder import os from qgis.core import * from PyQt4.QtCore import * indir = Input_Folder outdir = output_Folder for dirpath, dirnames, filenames in os.walk(indir): for file in filenames: if file.endswith('.txt'): fullname = os.path.join(dirpath, file).replace('\\', '/') filename = os.path.splitext(os.path.basename(fullname))[0] #type=(csv|regexp|whitespace|plain) , skipLines=n, useHeader=(yes|no), trimFields=(yes|no), skipEmptyFields=(yes|no), decimalPoint=c, xField=column yField=column [ If the useHeader is no (ie there are no column names), then this is the column number (with the first column as 1).] # crs=crsstring, spatialIndex=(yes|no) # see: http://qgis.org/api/2.14/classQgsVectorLayer.html uri = ( 'file:///%s?type=%s&skipLines=%d&useHeader=%s&trimFields=%s&skipEmptyFields=%s&decimalPoint=%s&xField=%s&yField=%s&crs=%s&spatialIndex=%s' % (fullname, "whitespace", 0, "Yes", "Yes", "Yes", ".", 1, 2, "EPSG:31468", "Yes")) layer = QgsVectorLayer(uri, "LayerName", "delimitedtext") if layer.isValid(): print "Loaded Layer %s is valid..."%(fullname) #QgsMapLayerRegistry.instance().addMapLayer(layer) #QgsVectorFileWriter.writeAsVectorFormat(layer, outdir + '/' + filename + '.shp', 'CP1250', None, 'ESRI Shapefile') else: print "Failed to load Layer %s" % (fullname)
