Geometry as Data Structure and Visualization

Introduction to Geometry as Data Structure and Visualization

Class, Computational Geometry, Data Structure, Projection, Remap, Interpolation, Generalization, Gestalk Principles, Principles of Graphical Integrity, Bertin’s Visualization design space

1) File format(CSV , JSON, GeoJSON, Image)
2) Geometry as Data Structure
2) Remap, Interpolation, Generalization
3) Object-oriented programming(OOP) pattern
4) Visualization


Structured data- CSV
Semi-structured data- JSON, GeoJSONlink
Image: Remote Sensing, DEMlink

Programming Paradigm / Typescript Classes
Software design pattern:
link, (GoF) Design Patterns
Inheritance (object-oriented programming):
