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:

structure :

functionality:

• (model)bld.)

• (db’s)

• question)normal.

• selection

• schema))tisation

• scenario bld.

• visualization

• data editing

• 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

• 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

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
