  1. 1. Geoloca'on  Enrichment  Tools   Geocoding  Applica'on   Stein  Runar  Bergheim   Asplan  Viak  Internet  AS  
  2. 2. Overview   What  is  it?   Why  it  has  been  made?   What  it  can  do  for  you?   How  it  was  made?   Step-­‐by-­‐step  guide  to  a   geocoding  project?   Exercises   Ques'ons      
  3. 3. •  A  tool  to  add  geoloca0ons  to  exis0ng  data   •  Can  be  used  with  any  tabular  data   •  Makes  it  easy  to  update  original  data  source   •  Easy  to  plug  into  exis'ng  work  flows   •  Crowd  sourcing-­‐ready  -­‐  create  with  users  for  users   locloud.avinet.no/demo   www.locloud.eu   What  is  it?  
  4. 4. Geography  excellent   for  explora'on   I  know  what  I  am  looking  for  and  I   know  it  exists  in  there   I  am  interested  in  informa'on  that  is   relevant  to  a  loca'on  (a  geo  en'ty)  
  5. 5. •  LiQle  XY  metadata   •  XY  only  way  to  integrate  ANY  content   •  Enables  map  based  presenta'on  and  explora'on   •  Opens  up  deep  content   •  Metadata  enrichment  at  source   •  Mul'  level  quality  control   Why  has  it  been  made  
  6. 6. •  User  management   •  Roles   •  Upload  CSV  text  files   •  Mul'  byte  encoding  support   •  Edit  'tle,  XY,  confidence  or  any  aQribute   •  Filter  by  area,  category   •  Add  point,  line,  polygon   •  Lookup  names  sources     What  it  can  do  for  you  1/2  
  7. 7. •  Lookup  other  map,  loca'on  providers   •  Add  WMS  layers  to  map   •  Select  base  map   •  Zoom,  drag  zoom  and  pan     •  Download  geocoded  data  as  KML,  GeoJSON,  RDF  and   CSV   What  it  can  do  for  you  2/2  
  8. 8. •  A  lot  of  people  contributed  to  the  specifica'on   –  LoCloud  partners   –  Rough  outline  sketched  during  LoCloud  kick  off   –  Acerwards  implemented  by  partner  AVINET   –  Tested  extensively  by  Riksarkivet   •  Released  under  GPL  and  supported  licenses   How  it  was  made  
  9. 9. A  selec'on  of  LoCloud  partners   during  kick-­‐off  meeitng  in  Oslo  
  10. 10. Demonstra0on   A  step-­‐by-­‐step  walk-­‐through  of  a  typical  geocoding  project  
  11. 11. Geocoding  Step  by  step   •  Prepare  file   •  Log  in   •  Upload  file   •  Create  users   •  Assign  access   •  Select  data  source   •  Filter  data  source   •  Select  item   •  View  informa'on   •  Specify  geometry   •  Select  base  maps   •  Edit  aQributes   •  Specify  confidence   •  Search  for  en''es   •  Use  alterna've  sources   •  Download  data  
  12. 12. Only  requirement  is  a   unique  id  and  a   representa've  name  
  13. 13. Data  sources   Top  menu   Item  list   Geocoding  form   Search  databases   User   management   Map,  map  tools   Search  results  
  14. 14. 90+  =  green   75+  =  yellow   20+  =  red   <  20  =  error   Map   resolu'on   also  stored  
  15. 15. Select  from   available   names  sources   When  clicking,   will  zoom  to   loca'on  
  16. 16. Click  to  open   with  same   extent  
  17. 17. Download  as   GeoJSON,  KML,   RDF  or  CSV  
  18. 18. Upload  file  
  19. 19. To  sum  up:  step  by  step   •  Prepare  file   •  Log  in   •  Upload  file   •  Create  users   •  Assign  access   •  Select  data  source   •  Filter  data  source   •  Select  item   •  View  informa'on   •  Specify  geometry   •  Select  base  maps   •  Edit  aQributes   •  Set  quality   •  Search  for  en''es   •  Use  alterna've  sources   •  Download  data  
  20. 20. •  Star'ng  with  X  million  non-­‐geo  records  is  difficult   –  Will  take  a  long  'me  to  reach  interes'ng  sample  size.   –  Easier  to  get  help  to  improve  than  create  from  scratch   •  Solu'on:  combine  automa'c  and  manual  approach   •  First  auto-­‐enrich  using  available  tools   –  List  tools  (AnnoCultor  etc)   –  LoCloud  Geocoding  Tool  for  Desktop   •  Then  use  LoCloud  Geocoding  Tool   Automa'c  Geocoding  
  21. 21. LoCloud  Geocoding   Tool  for  Desktop   Involves  poten'ally  hundreds  of   database  lookups  per  geocoded  record     Best  suitable  for  desktop  in  order  not   to  «break»  or  «overly  stress»  shared   server  infrastructure     Adapted  to  specific  na'onal  datasets  –   key  registries  include:   •  Property   •  Address   •  Persons   •  Named  en''tes   At  the  outset  adapted  for  Norwegian   registries  but  can  easily  be  adapted  to   any  other  European/na'onal  key   registry
