Line Length Calculations and Stats with QGIS

In this tutorial, we are going to learn how we can do math operations on lines and get statistic summary in GIS software known as QGIS. First, I will explain how to use the “Field Calculator” operation to calculate the length of the line features in the vector data you are working with. It will show you how to create new fields and how to apply the required expressions to obtain as accurate a figure as possible for the length of the line segments in the given dataset. This tutorial is ideal for any GIS professional and ancillary enthusiasts who would want to extend their proficiency in spatial analysis.

After the length calculations, next, we are going to discuss on how to generate and display statistical summaries for the line data. That is why in this part we will explain how to perform the analysis of data in QGIS, knowing the distribution of line lengths, creating statistics, and displaying graphical charts and graphs. After the completion of this tutorial, you will be able to analyze and interpret the line length data in a proper manner and thereby you can make your GIS work more informative.
