The Geostat Hypotheses;

In search of a high resolution foundation for Geostatistics, an interactive response to

operational user needs in a time of transition.

We need a shared Reference

documents)– Properties (statistics)– Cartographies (geodata)– Reference literature (reference library)

We need a data Infrastructure

Double perspective : (1) ” Interacting wholes” and (2) ”Kits of Parts”

Dynamic Models

Narratives

Object models

Map Features (points, lines and polygons)

Dynamics (objects and their relationships) over time

We need to adapt our Statistics

We need an infrastructure for Spatial Analysis

Why Grids?

A foundation for statistics ”liberated” from administrative areas with:

1. Full coverage (covers land and sea)2. Fixed, neutral system of small statistical areas (does

not change over time)3. Suitable for (cross disciplinary- cross border-) spatial

analysis4. Fully scalable for local and global use 5. Compliant with existing key technologies for data

capture6. Widely used both in Science and Practice

Warm ocean waters fuel hurricanesWarm ocean waters fuel hurricanes, and there was plenty of warm water for Hurricane Katrina to build up strength once she crossed over Florida and moved into the Gulf of Mexico. This image depicts a 3-day average of actual sea surface temperatures for the Caribbean Sea and the Atlantic Ocean, from August 25-27, 2005. Every area in yellow, orange or red represents 82 degrees Fahrenheit or above. The data came from the Advanced Microwave Scanning Radiometer (AMSR-E) instrument on NASA's Aqua Http://science.hq.nasa.gov/earth-sun/missions/satellite_17.htm

Spatial analysis

The ”Kit of parts” perspective:

• Required for both Ex Ante and Ex Post purposes!– Analysis, planning, implementation and evaluation of both

direct and indirrect action.

• We are good at: – spatial analysis of the envionment

• We are less good at:– spatial analysis of society

Conclusions

1. “Think global, act local”The Systems perspective: A view to both the whole and the parts!

2. “If you cannot describe it you cannot manage it”Integrated Modeling with Objects in Space and Time: An Integrated model!

3. “Proof of the apple is in the eating”Utility: The ultimate proof of the GSS is its function as a practical tool!
