Creation of Buffer zone using Python in QGIS

Hi Viewers,
In this video, you will come to know the python program coding for the creation of buffer zone for point features in QGIS.
Find the program below for your reference.
iface.newProject()
iface.addVectorLayer("d:/msr-geospatial-solutions/qgis-python/points.shp","points", "ogr")
InputFile = 'points'
OutputFile = "d:/msr-geospatial-solutions/qgis-python/bufferzone.shp"
bufferDist = 0.02
##To get the fields from map layer
Data = QgsProject.instance().mapLayersByName(InputFile)
layer = Data[0]
fields = layer.fields()
QGS Vector File Writer will create buffered features and add to output file.
writer = QgsVectorFileWriter(OutputFile, 'UTF-8', fields, \
QgsWkbTypes.Polygon, layer.sourceCrs(), 'ESRI Shapefile')
Geometry along with buffer. Use writer to add the feature to the buffer layer.
for f in layer.getFeatures():
geom = f.geometry()
buffer = geom.buffer(bufferDist, 0.02)
f.setGeometry(buffer)
writer.addFeature(f)
print('done')
Run Python code
##Finally, add the buffered layer to the QGIS interface and delete the writer.
iface.addVectorLayer(OutputFile, '', 'ogr')
del(writer)

Great info. Proximity analysis can be done using this easily.

[@msrgeospatialsolutions]

Thank you for comment priya.. Yes, buffer can be done for any feature type. It may be useful as per requirement.

Awesome video - indeed helpful! also do you know what parameter to change if I wanna create square buffers instead of circles? Thanks!

[@msrgeospatialsolutions]

Thank you for the comments. I will let you know the details, if possible. Keep follow for the updates.

Python is in add in plugs??

[@msrgeospatialsolutions]

Yes, Python is inbuilt in the form of python console in both QGIS and ArcGIS.
