 Hello, this is Hans van der Klaas, senior lecturer at IHGDALT Institute for Water Education. In this video I'll show how to add the white box tools to QGIS. So you can use over 450 tools from the processing toolbox. It also supports other software than QGIS and has a standalone tool, but in this video I'll focus on installing it in QGIS. On the website you'll find a lot of examples on how to use these tools, what are the applications, like here in precision agriculture or having shadows in the DEM. The developers are John Dincey and Anthony Francioni and they did a great job in making these tools and making them available as open source. And most of the tools are about terrain analysis, hydrology and lidar. So we're going to download the tools and you need to choose the operating system that you use. You can use Windows 64-bit, you can fill in the form to let the developers know how you're going to use it and who you are, but it's voluntary and you can click submit and download and then save the zip file and after downloading you can open the zip file and extract it to your hard drive and I extract it to C, so I'll have the folder CWBT that will contain the executables. Now there are some instructions on how to then integrate it in QGIS, here you see some more examples of the nice things you can do with this tool or with this toolbox and in future videos I'll show some more applications. So we are going to install it for QGIS, so I click here on learn more to see the instructions and the white box tools are very well documented, so it's also very useful to help you in your analysis and here it gives some instructions on how to install it. It is not available from the regular repository, so you need to copy this link and then in QGIS you need to go to settings in the plugins manager and click add, give a name to the repository, I'll use the name that was suggested and then paste here the link and the rest you keep as default and now it's loaded the plugin repository that we've just added and now you can find the white box tools for processing. Click install to install it, close the dialogue and then go to the processing toolbox and there we need to change a setting before we can use it, so the plugin basically connects QGIS to the executables but it needs to know the path, so here in these settings you can set the path and you can browse to the place where we have saved our executables, so that was on C in our case there it is and I point to the white box tools executable, click open and then okay and from now on we can use those white box tools from the processing toolbox and as you see they are categorized and if you expand them you'll see that there are many tools added now to the processing toolbox that you can use, for example for stream network analysis, for LiDAR and for sure I'll make some more videos on demonstrating how these tools can be used in practice.
