M. Kordouli, Landslide inventory using GISMA techniques., Δελτίο της Ελληνικής Γεωλογικής Εταιρείας, 47|2013, 1472-1478

The use of GIS for various types of data is considered to be of high importance, mainly  because  it  is  bringing  together  information  from  multiple  sources.  In addition, the new Internet technologies and applications of global world maps, like Google  Maps,  give  the  opportunity  to  build  systems  that  the  geographical information can be recorded and administrated by many users from anywhere. This kind  of  GIS  systems  is  suitable  for  Business  Administration,  or  Science,  or Government Organizations, which need GIS systems with multiple users from many places  and  multiple  kind  of  information.  This  system  is  defined  as  GISΜΑ (Geographic Information System Multi Administration). In GISMA many users may input  the  data  and  use  the  information  from  different  distance.  Each  user  has specific permissions of use of data as the administrator sets.  In  this  work,  the  basic  principles  and  rules  of  a  building  GISMA  system  are evaluated and an application is presented based on data and GIS techniques for the slope instability studies. Data obtained from historical landslide occurrences were verified with new locations obtained from high resolution orthophotos and Google Earth  application.  Landslide  areas  were  mapped  using Arc  Map  and  finally  the Landslide Inventory for the Achaia’s Prefecture was created.
