How to format the\nprocessing<\/strong> toolbox<\/strong> <\/p>\n\n\n\n Firstly, we will make sure the processing\ntoolbox is correctly formatted\n to access and\nrun\nthe GRASS, SAGA, TauDEM and LAStools algorithms . Most\nlibraries required are installed\nautomatically\n, but the configuration of these tools\nvary\naccording\nto the operating system and to how you have installed\nQGIS. The toolbox formatting includes essentially\nthe activation or deactivation\nof a library , as well as the\ndefinition of the directories used. \n\nTo open the formatting window\nyou must\nclick\non the menu Treatment<\/em><\/strong>->\nOptions …<\/em><\/strong><\/p>\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nTo start,\nyou must ensure that each of the\nlibraries you plan to use is activated and, according to your\noperating system and installation chosen , you will, perhaps, specify the necessary\ndirectories to execute TauDEM , LAStools , and R. The following figure shows that each of the libraries is activated and that the\ndirectories required are thoroughly specified . \n\n\n\n<\/p>\n\n\n\n Clicking OK<\/em><\/strong> updates the display of the toolbox. If you do not use some libraries simply uncheck the Activate<\/strong> box. This simplifies the toolbox.\n<\/p>\n\n\n\n Overview<\/strong>\nof the toolbox<\/strong>\nstructure<\/strong>\n\nFor\nthe time being, we have not really discussed the interface. We have simply formatted an perhaps, installed the libraries\nrequired to make the function available in the toolbox.\nTo display the toolbox, you must click on the Process<\/em><\/strong>\nmenu -><\/em><\/strong>Toolbox<\/em><\/strong><\/p>\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nThe\nprocessing toolbox appears on the right side of the QGIS interface . \n\n\n\n<\/p>\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nHowever,\nby default, most providers algorithms are not visible. You\nmust click on the option\nSimplified interface<\/em><\/strong> that is located\nthe bottom of the toolkit window, scroll through the available options and select so display advanced . \n\n\n\n<\/p>\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nAfter\nselecting the\nadvanced interface option , finally, you will gain access to the algorithms complete list toolbox: \n\n\n\n<\/p>\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nAt\nfirst, you see a list of various libraries\nand the number of available algorithms in each of them . When you click the +<\/strong> next of\nentries, the list expands to display the subdirectories that bring together\ndifferent tools . In addition to browsing manually\nthrough these directories,\nthere is a search field at the top of the\ntoolbox. If you are\nalready familiar with libraries and you look for a specific tool, this can be a more efficient way\nto access the algorithms . Even if you are not familiar with the libraries, you can always use the search box\nto discover which are the available tools. For\nexample , if you are\ninterested in the different ways to visualize or explore the topographic\nrelationships , you might search by typing \u00a0\u00bb topograph \u00a0\u00bb in the text box and discover\nthat there are ten tools from three different suppliers that relate to the topography . \n\n\n\n<\/p>\n\n\n\n To launch a processing,\nyou just have to double click on its name in the toolbox window. The setting window opens\nautomatically . \n\nThe\nprocessing toolbox provides, also, an additional option allowing\naccess to underlying processing. To that end, you can open an online command window by\nclicking on the Process<\/em><\/strong> menu -><\/em><\/strong>Command<\/em><\/strong>Line.<\/em><\/strong><\/p>\n\n\n\n It should be noted that\nby typing \u00ab\u00a0grid\u00a0\u00bb in the search box , you\nget a list of the available algorithms concerning the grids. The main\ndifference between the two types of research is that when a tool is selected in the drop list of the command line, it opens automatically . Therefore, once you have\na certain degree of\nfamiliarity with the names of the specific tools, the\ncommand line can increase, significantly,\nyour productivity .\nNow that the QGIS processing toolbox is correctly\nformatted and that you have\nan idea of \u200b\u200bhow it works and its overall organization\n, you can start using it and you will save a few blockages ! <\/p>\n","protected":false},"excerpt":{"rendered":" When we need to use a tool of the QGis toolbox, it is usually in the heat of the moment and we omit some preliminary configuration points .

\nFor\nexample , if you have\nused\nthe\nOSGeo installer\nyou can use the Installation\nadvanced option to install GRASS 7 otherwise\nyou\nmust\n manually install GRASS 7 and configure the directories\nin\nthe toolbox.
\nIf\nyou cannot find a configuration option in the toolbox for a given package, it\nmeans it is not installed .\n
