PointConnector

A QGIS plugin used for creating lines between points following a from-to list.

Usage

####Inputs:

  • An ESRI shape-file with points or an existing point layer in the map document. The first (or only) field should contain the joining attribute found in the from-to list.

  • A comma separated txt-file (CSV-file), or table in the map document, formatted like this: [from], [to]. Each row results in a straight line between the two corresponding points.

    Example:

    Stockholm, Paris

    London, New York

    Paris, London

    ...

When using special characters make sure the file is saved with utf-8 encoding or import the file to the document first.

####Output: A layer with lines, each with from- and to-attributes.

Background

PointConnector is the result of a problem I faced working with a geographical analysis for the local school authority. I needed to show the distance between kids homes and preschool on a map, each kid represented with a line from their home to the school. A total of 18 000 lines needed to be drawn, and it should be easy making a new version of the map each semester. My input was the schools register and georeferenced addresses for the city. The result is a basis for analysis, for planning new school locations and seeing other patterns.

PointConnector has also shown to be a useful tool for creating input to the FME transformer ShortestPathFinder
