Accessible Navigation
Creating an interactive cartographic map presents unique accessibility challenges. Screen readers cannot natively interpret 2D Canvas or SVG coordinate locations without explicit semantic structure. To ensure no user is…
Spatial Cartography and Navigation
Concept mapping, Self-Organizing Maps, graph pathfinding, accessible navigation, and wayfinding across complex learning journeys.
Triangulating in Complex Concept Spaces
In physical geography, wayfinding involves orienting oneself relative to known landmarks, assessing terrain contours, and choosing pathways that reach a destination. When applied to digital knowledge management…
Concept Mapping and Self-Organizing Maps
Generating a cartographic topological map from a collection of text documents involves a multi-stage Machine Learning pipeline:
Graph Traversal & Pathway Interrogation
Early cartographic web prototypes constructed road lines based on global document hyperlinks or raw Euclidean distance across the map. However, drawing long diagonal lines across the canvas creates visual clutter and…
Discrete Voronoi Topic Territories
In early iterations of spatial concept maps, topic regions were rendered as overlapping translucent rectangles or ellipses. While simple to compute, overlapping shapes created visual clutter, blurred domain boundaries…
