Hi Viewers,
From this video, you will come to know the process of estimation of length of line features by using Python program in QGIS.
Find the program code here:
Steps to follow:
## 01. Add Vector layer
## 02. Active Layer
##03. Feature details (Fields)
for f in features:
##04. Add Field
from PyQt5.QtCore import QVariant
##05. Code to update length field
for f in features:
attr_value={4:length}
## RUN Python
