Currently we are working in a geological project..in which all the Contacts, Linear & some other geological features have to be captured.
The thing is most of the features have to be Captured as "Line" and then it has to be converted to "Polygon". So that we don't have to repeat the digitization for features like Contact....
1) Is it not at all possible in Qgis to Snap a line with the same line ? like that of in AutoCAD, Mapinfo..?? (Image 1)
2) I've captured a polygon as two separate lines...and when i use "Line to Polygon" (Enclose in the case of Mapinfo)....it actually creates two polygons instead of one single entity. Is it a bug ? (Image 2)
I am trying to convince some of colleagues (and the management as well) to switch over to QGIS..atleast in few systems...So i am trying to figure out the available functionalities in QGIS as that of MapInfo. So any sort of feedback will be of great help.
Update: Polygonize command does the trick of converting the two separate lines into one single polygon feature...(Image 2).
