You have to georeference the raster first. Its not just about a CRS, but the extent of the raster (in CRS units) too. You make yourselve double work if you digitize data from the raster, and then try to adjust that to reference maps like bing. There are a few tools to georeference vector data, but you will not have the convenient "pick from canvas" tool.


In a new project the tool works fine. It has no Bing layers.The CRS is the same for all layers and project.


One method is to use a virtual field which would automatically number your points using the $id expression (or whatever expression you prefer): Note that you will need to save a project file for this as virtual fields are saved in the .qgs file and not in the shapefile itself (but you can re-save the shapefile as a new one using the Save As... option ...


I think you talk about the id of shapefiles, if so you can go to layer properties (doubleclick the layer) then go to fields and set the item that is called 'Bearbeitungselement' in german to UUID-Generator (id field type must be text) as shown in the screenshot below ( When digitizing your ...


The Digitizing tool does not work correctly with on-the-fly reprojection. If you need the project CRS to be EPSG:3857, reproject the shapefiles layers using Save As ... to another filename and EPSG:3857, and remove the original layers from the project. Then you can use the digitizing tool without error messages. Once finished with digitzing, you can save ...


You should change you project CRS to match that of the layer you are editing, and not the Layer's CRS from it's properties menu, as that is simply incorrect.


There are a large number of FOSS options that would be suitable for a project like this. I am going to end up recommending that you use QGIS. I will address the question in three parts: Non-GIS options. GIS options, and why I recommend QGIS. Some pointers to QGIS tutorials. Non-GIS options Since you have come to a GIS-focused site, you are indicating ...


If you do choose to use a CAD, rather than GIS program for your needs, There are also open-source CAD programs like QCAD.


A free tool that will help you explore what you can do within GIS, is QGIS. It will most likely be a little tricky to digitize and import the information but you can start with loading a basemap (say Openstreetmap) and trace out the boundary of your property. Then, you can try to import some scans of your paper copies and geo-rectify them. This just means ...
