How to Generate Contour Lines with QGIS – Step-by-Step Guide

Image
  Introduction Creating contour lines has always been a recurring task in my projects, QGIS stands out as an excellence choice. As a free and open-source software, QGIS combines ease of use with robust capabilities, making it a go-to solution for geospatial analysis. In this post, I'll guide you through the process of generating contour lines using QGIS, sharing tips and ticks I've picked up along the way to streamline the workflow and ensure precision. Step 1: Add a DEM TIFF To begin generating contour lines in QGIS, the first step is to load your Digital Elevation Model (DEM) file, typically in TIFF format. Here's how: 1.  Open QGIS : Launch the QGIS application on your system. 2. Add Raster Layer : Navigate to the Layer menu at the top. Select Add Layer > Add Raster Layer . Alternatively, you can click the Add Raster Layer  icon in the toolbar. 3. Locate Your DEM File : In the file browser, find your DEM file (eg., .tiff) and click Open . 4. View the DEM : Your DE...

How to configure truststore at springboot

Image
In this tutorial, we would like to setup a truststore in our springboot application. To support https in SpringBoot, we need to generate self-signed certificate by java keytool. I assume that a springboot application is ready. We are going to focus on keystore and truststore configuration. In this step, we as a server. We need to generate a java keystore by keytool. keytool -genkey -keyalg RSA -alias dataflow -keystore dataflow.jks -keypass dataflow -storepass dataflow -validity 365 -keysize 4096 -dname "CN=localhost, OU=spring" if we run our application at local environment, CN set to localhost. eg. CN=localhost. Now, we as a client. We want to generate client certificate. We named the keystore as client_keystore . The step is similar the step on top.  keytool -genkey -keyalg RSA -alias client -keystore client_keystore.jks -keypass password -storepass password -validity 365 -keysize 4096 -dname "CN=user, OU=spring" After that, We would like to co...
