ISPRS - Technical Commission II 2012-2016

Theory and Concepts of Spatial Information Science

Our Mission:

The goal of the work and activities of Technical Commission II is to advance the research, technology and applications of spatial information science. The first focus is on development of efficient representation and modeling for multi-scale, multi-dimensional and multi-temporal data. The second focus is on the design of methods, tools and algorithms for integrating, managing, mining and visualizing of existing and newly created multi-resolution spatio-temporal sensor data for use in spatial decision-support systems. The third focus is on the development of server, web and mobile frameworks to enable high performance computing (e.g., grid and cloud computing) for big geospatial data processing and geospatial modeling and simulation. The fourth focus is on the quality control assessment of spatial data and analysis at multiple scales using existing and new approaches to spatial uncertainty modeling including multivariate statistics, crowdsourcing and citizen science.
