I am writing some basic QGIS training notes and I came across this post Is it possible to change the field length of a shapefile to over 254?
However the maximum field length of a shapefile, I believe, is 254.
This based upon other GIS SE answers:
- Maximum length of text fields in shapefile and geodatabase formats?
- Does joining CSV file to shapefile overcomes the 255 character limitation of shapefile?
and the Wikipedia https://en.wikipedia.org/wiki/Shapefile#Limitations
Should the original question be edited, a comment made, or the 254 limitation added to an answer?
