Bloch's function D for weighted effective areas : impact of tuning parameters
Book
Visvalingam, M. Bloch's function D for weighted effective areas : impact of tuning parameters

Abstract When Visvalingam’s algorithm was first presented, it was noted that it could be driven with any metric to suit different purposes, types of features and degrees of generalisation. It was illustrated with the concept of the effective area (EA... Read More about Bloch's function D for weighted effective areas : impact of tuning parameters.

Geometric data for testing implementations of point reduction algorithms : case study using Mapshaper v 0.2.28 and previous versions
Book
Visvalingam, M. Geometric data for testing implementations of point reduction algorithms : case study using Mapshaper v 0.2.28 and previous versions

There are several open source and commercial implementations of the Visvalingam algorithm for line generalisation. The algorithm provides scope for implementation-specific interpretations, with different outcomes. This is inevitable and sometimes nec...
