Using QGis or ogr2ogr how do I convert a vector file containing multiple linestrings features into a single multilinestring feature?

At the moment I've been doing this manually by converting the data to GeoJson and editing it manually.


You can use the Dissolve tool from QGIS:

Vector > Geoprocessing Tools > Dissolve

Dissolve toolbar

Dissolve interface

  • Just what I needed. Never would have guess Dissolve was it. Thanks!
