Overview
• GISMOD: What ?
• GISMOD: Why ?
• GISMOD: How ?
• GISMOD: When ?
3
GISMOD: What ?
• “model”
• “process”
Objective: Towards a generic geo process model player
• “geo”
• “generic”
• “towards”
• “player”
4
GISMOD: Why ?� initial objective:
“we need GIS Standardization at WAU”– GIS software
– models
� present objective:comprehensive tool for geo process modelling in education
– geo process models– geodata– presentation
5
GISMOD: How ?
the Geo Process Modelling Procedure
1. questions to be answered by a model 2. selection of a suitable model3. preparing the data, needed by the model4. telling the model what to do5. presentation of the model results6. feedback / edit /adjust
components:

functionality:
• (model)bld.)
• (db’s)
• question)normal.
• selection
• schema))tisation
• scenario bld.
• visualization
• data editing

the Geo Process Modelling Procedure: questions
�questionsmodel selectiondata preparationscenario buildingpresentationfeedback / edit• concept
• relevant context• knowledge domains• model availability info
• challenge •develop ‘geo process question parser’
• results • none, so far
8
the Geo Process Modelling Procedure: model selection
questions�model selectiondata preparationscenario buildingpresentationfeedback / edit
• results • very proto
• challenge • metadata structure for models
• model bank, poly.domain
• relevant context•db with model descriptions
• standard geo process model format
• concept • metadata based selection

prepareddataset
• relevant context• data availability
• data usefulness
• preparation tools, avl.
• challenge • schematisation proc.
• results • none, so far
10
the Geo Process Modelling Procedure: scenario building
questionsmodel selectiondata preparation�scenario buildingpresentationfeedback / edit
• results • only simple editor
• concept • food, fit for the model
• relevant context • selected model• schematized data
• challenge • translate “scenario” to scenario
11
the Geo Process Modelling Procedure: presentation
questionsmodel selectiondata preparationscenario building�presentationfeedback / edit
• challenge • visualisation through the web
• results • 2D Local, 3D via internet
• relevant context• models local ?• model run results (local !)
• initial dataset (local !/?)
• visualisation tools (local ?!)
• concept • 4D geo.graphics preferred

questionsmodel selectiondata preparationscenario buildingpresentation�feedback / edit
the Geo Process Modelling Procedure: feedback / edit
• challenge • interactive 3d editor Xweb
• results • expected fall 2000
• relevant context •web.based vis. server
• interface authoring possib.’s
• concept•model output presentation based data / scenario editing (allows ‘interactive design’)

GISMOD: When ?• question handling (‘manual’): NOW
• inserting standard formatted model: NOW
• model selection (‘manual’) : NOW
• data preparation (external): NOW
• scenario building: NOW
• presentation 2D : NOW3D : FALL 2000
• feedback / edit: FALL 2000
