I want to create an elevation model in EPSG 4326 from 2 shapefiles [img0] : elevation lines [Altimetria linee Antrodoco] and elevation points [Altimetria punti Antrodoco], both obtained by the District Maps database of Lazio. However I encounter several errors and/or weird rasters as a result, depending on my Interpolation settings:
a) if I choose both Points and Lines as Input [img 1 in the link above] and set them as Structure lines and Points respectively, I get minidump error [img 2], no matters the cellsize or columns values.
b) if I choose both Points and Lines as Input [img 3], and set both of them as Points, I do not get errors, but I get alwais messy/weird lines, that do not seem to follow the elevation lines at all [img4]. This happens also with clipped shapefiles.
c) all in all, whenever I choose points or lines, as soon as I change the cellsize to get 5 (project unit is meters), the rank and columns change to 0. [img 5] Only with values inferior to 0.00x I get positive ranks and columns value [img 6], independently from the size of the layer.
Since I'm a beginner, I believe there are probably many errors and issues braided together. What is the first/main problem in my procedure?
I can't add more than two links, so I put all the images in the first gdrive folder.
