[Qgis-user] Lookgin for two shape editting tools

[Camilo Aristizabal]

Hi Nicolas
Thank you for your attention.
I'm going to try the second and third tips you sent me, and I'll inform you.
But the first one is just that I'm trying to avoid because I need to report both, the start and the end of coordinates of the lines in the same *.dbf of the vector line, and not in a second shapefile of points.
Could you help me to find the correct tool?
Best regards.

Dear all
I'd like to do the next set of edition tasks:
1) Add XY coordinates at both the start and the end of lines in a shapefile (avoiding to create or extract a second point-shape of specific vertices).

You can extract specific vertices and then use the field calculator to get the coordinates 
https://docs.qgis.org/3.16/en/docs/user_manual/processing_algs/qgis/vectorgeometry.html#extract-specific-vertices


2) Extract the envelope or to poligonize just the border of a cloud of points(shapefile)... Similar to such with which do it from a raster in the GDAL Raster Conversion tool.

This can be done with a concave hull.  A better alternative are the boundary tools in Lastools.

3) Create 'string' or 'text' fields with much more than 4000 characters of width inside the shapes, not only 255.

I you use a file format like geopackage, you will not be limited to 255 like the shapefiles.


Could you, guys please, help me to find the right paths?
Thanks!

Camilo Aristizabal
