 Hello, welcome back on my YouTube channel. In this video I'm going to show some updates from the PCRusterTools plugin. You can install the plugin from the plugins menu and you see that version 0.30 has been released. You need to install the plugin but remember you also need to install PCRuster which is covered in other videos or you can read the steps in the documentation. Let's open the processing toolbox and have a look at what the changes are. Under data management you'll find now a new tool, PCRusterMapsToColumnFile. Later in this video we'll have a look at how that works. We have also changed a little bit the LDDcreate tool and related tools to also accept decimal numbers for the arguments. Let's have a look at the PCRusterMapsToColumnFile tool. I'm going to apply this to a LensSurfaceTemperature image and an NDVI image. Both images have been converted to the PCRuster format using ConvertToPCRuster format and I made sure that they are of the same dimensions so you can use the resample tool to make sure that they are of the same dimensions. Now I'm going to use the PCRusterMapsToColumnFile tool and this uses the mapToCall command that comes with PCRuster and if you click the link you get the documentation and we have implemented it in such a way that it gives for a set of input rusters a comma separated file with the X and Y coordinates of each pixel and then in each column the value of the raster. So I'm going to save the text file to LST underscore NDVI.CSV and then I'm going to run the tool and here also in the log you can see the order. So first we have LST and then NDVI. I refresh the browser and I add the CSV file that has been created by the tool and I can open the attribute table. It doesn't have headers but I can here see that the first column is X, then Y, then temperature and then NDVI. With the DataPlotly plugin I can now create a scatter plot based on this table. Let's install the DataPlotly plugin, click on the DataPlotly icon in the toolbar and the panel opens. I'm using a scatter plot and I'm using here field4 as the X field which has our NDVI and for the Y field I use field3 which is the temperature. You can change here the legend title, plot title and just doing this quick and dirty for the demonstration. Let's label would then be NDVI and the Y label LST. So add units. You can change a lot more settings but I'm just going to create the plot here and the plot fits the dimensions of the panel. So if you want to X and Y dimensions changed then just expand the panel. You can also use the CSV file in spreadsheet program or use it in Python but here I'm importing it into LibreOffice calc. I can just open the file from the menu and it will recognize that it's comma separated. Click OK to add it and then here I have X, Y, temperature and NDVI and I can then easily create a scatter plot using the tools from the spreadsheet program. I'm just going to do it quick and dirty here but you can further explore how to add a trend line. So I choose here scatter. I'm going to swap the X and Y columns because I want NDVI on the X and temperature on the Y. I'm going to write the title. This is axis label, this is label, that's not needed. Expand the graph. I could further change the range of the Y axis and the trend line in our square.
