Custom Clipping in QGIS

[Music] hello this is a video on how to make a custom selection if you want to crop data or clip data and this is also my third time recording this because I've got microphone issues okay so let's say you have some data here I've got the ancient woodland of England in the background and you want to crop it and this is how to do it you need to add a new layer a new shapefile layer click the sky and really important here you want to hit polygons on the radio dial click OK it'll ask you for a place to save it and give it a name of this selection ok then in selection you want to go to toggle editing look at this guy here and then you just zoom in on the area you want here will do is this Bristol good news click on add feature it's this green pawn shape icon in the top left corner here click that and then for the add feature an operation just left click left click the left click left click and then to end your selection you want to press the right click button you can't press into our space bar that doesn't work right click ok and the last year for each once you input in some attributes you can do this later if you want me to click OK okay so that's our selection great let's save that saving saving saving and we've come out ok so now we need to clip this clip use this as our mask to clip from the ancient woodland dataset so go to vector geoprocessing tools and clip your input vector layer ancient woodland England and the clip layer is the one I just made called selection and if we need an output here we'll do I'll call this ancient wood Lynde Eclipse that's good okay now do its magic I hope this works it'll work hey he tells himself I reassuringly okay I whip so just it's already done it thank you very much as we're done okay so if I turn off the ancient woodland data set turn off my little selection and there we have it that's the ancient woodland clips now if you want to export that into a DXF just go to edit the room and you can drag that thing into effect to work so AutoCAD and hopefully it won't crash on you and you wait hope that was helpful so I forgot to talk about this one feature if you want to make a selection like a rectangle or circle I don't think Hugh just has one built in but there is a workaround and this plugin called and rectangle ovals there we go rectangles ovals digitizing just type in rectangle overalls digitizing there it is and you've installed this plug-in you can make a rectangle selection so I'm okay so you enter toggle editing mode and then you click on one of these options to pack extent zoom in zoom in zoom in zoom in and you hold down the left mouse button release that's it okay there we go save okay so that could be helpful the way again
