Searching for Algorithms and Spatial Forms

Today I’m in a spatial data analysis quest to find algorithms to draw areas which are going to allow me to transform an image in an ‘arpillera map’. An arpillera is a traditional chilean craft of tapestry, born in Isla Negra (unknown year) and produced mainly by women. Specially famous are Violeta Parra arpilleras and arpilleras created by the families of the victims during Pinochet dictatorship.

Arpilleras are a singular artistic expression, due its protest message similar to grafiti. Also are special because are made using cheap materials like fabric and threads, transforming this art in a powerful platform to communicate.

My idea is to create spatial forms trough algorithms applied to spatial data in urban areas, creating a tapestry map. My idea is that tapestry gives me a more permanent map, not just a data visualization visible in the web for a ephimeral time. My goal is to create a long time map.

My approach until now, is this Voronoi produced using point from Open Street Map for London as an example:

RM-Voronoi
