Question-Based Spatial Computing - A Case Study
TLDR
We introduce an alternative approach to spatial analysis, based on the idea that users should be able to ask questions about the environment, rather than finding and executing procedures on map layers, and use data abstraction instead of procedural abstraction to structure command spaces. Expand
