8th  Phase  of  the  GEOSS  Architecture  ImplementaDon  Pilot  (jan-­‐2015)  …  4.  Build  toward  the  vision  of  the  Model  Web:  

•  Models  are  the  codifica6on  of  the  best  understanding  we  have  about  physical  phenomena  and  processes  and  should  be  further  applied  

•  The  vision  of  the  Model  Web  is  to  serve  as  the  basis  for  development  of  a  dynamic  web  of  models,  integrated  with  databases  and  websites,  to  form  a  consulta6ve  infrastructure  where  researchers,  managers,  policy  makers,  and  the  general  public  can  gain  insight  into  “what  if”  ques6ons

How  to  incorporate  crowd  sensing  data  to  the  model  •  Overall  principles:  

–  Ci6zen  supplied  absolute  head  levels  aren’t  useful  (no  unique  way  to  measure  it).  –  Ci6zen  supplied  changes  in  6me  are  meaningful.  –  Observed  measures  in  a  controlled  network  are  more  valid,  both  in  absolute  or  

rela6ve  terms.  –  Computed  (absolute)  values  must  be  corrected  for  each  user  according  to  the  first  

supplied  absolute  value.

What’s  innovaDve?     What’s  the  impact?  

Groundwater  model  results  as  Linked  Open  Data  (LOD)  

Link  geospa6al  data  with  groundwater  data.  Basis  to  expand  LOD  to  model  results  of  different  areas.  

Model  Web  as  consulta6ve  infrastructure  

Best  understanding  of  physical  phenomena.  General  public  can  gain  insight  into  “what  if”  ques6ons.  

Smart  Regions   Public  informa6on  extended  to  territories.  

Numerical  models  2.0:  Models  driven  by  ci6zen  data  

Public  par6cipa6on  in  both  direc6ons.  Model’s  quality  increases  with  new  observa6ons.
