I have multiple (50) layers representing rivers and creeks which are polylines. However, they are broken into line segments so each river/creek layer might have 30 or so features within it.
I know how to select and merge features within 1 layer but is there a way in QGIS to do this as a batch process with all 50 layers?
Otherwise, I have to manually go through and merge each line layer separately.
Perhaps someones know of a script to perform this. The process for 1 layer is:
- open layer for editing
- open attribute table
- select all in table
- merge selected features
- close and save
Essentially I need to run these 5 processes on each of the 50 layers?
