As a reminder, vectorization creates all the necessary vertices and paths as shown with the building outlines. In a nutshell, this tool digitizes the raster for you to convert it to a vector. If you want tolearn how to vectorizeacontinuous raster, this will take a bit of effort to reclas...
So essentially what I'm asking is does anyone know of a plug-in for QGis that gives me similar functionality to that in sketch-up, and if not can anyone suggest a way (or workflow) that would allow me to capture the building footprints while keeping the edges orthogonal to each other,...
But when I digitize a new point, I always get the same ID, with 1 at the end. From what I've deduced, the code works up until I add thegroup_by:=argument to themaximum()function. Weirdest part is, it used to work all the time ... like this morning, had no problem...
The transparency of the whole layer can be set in layer rendering https://docs.qgis.org/3.22/en/docs/user_manual/working_with_raster/raster_properties.html#layer-rendering For digitising purposes set the layer rendering to multiply, this makes the layer transparent for the light colours. https:...
You can digitize the border of the polygon. Just make sure of a) Set the proper snapping options at settings/snapping options for this case I will snap on the vertex of the existing polygons with a tolerance of 15 pixels. More important, I set that I do not want intersection of new ...
Using QGIS, I am trying to digitize an old raster map, and because I ultimately want to load these 2d layers into sketch-up to turn into 3D models, I need everything to be square. Here's a sample of the map I'm working with: The green lines you can see are a vector layer of ...
