DESCRIPTION:This presentation introduces a new step-by-step approach that a
 ims at helping to fix the incompleteness and heterogeneity of the OSM data
 . \nIt first focuses on the OSM features that comprise the backbone of hom
 ogeneous OpenStreetMap data\, before broadening the perspective to include
  other objects: the nodes representing settlements\, the main road connect
 ing them to the main road network\, as well as the residential area showin
 g the extent of the settlement.\nThe OSM Skeleton project aims to identify
  all missing\, inaccurate\, incomplete\, or obsolete objects in the OSM da
 ta backbone in order to resolve inconsistencies. OSM Skeleton uses externa
 l data to identify the missing features and performs spatial analysis\, cr
 ossed features and various metrics to analyze incompleteness and heterogen
 eity. For instance\, the approach introduces a hybrid analytic feature tha
 t combines residential and street network areas. \nEach type of issue\, wh
 ether confirmed or potential\, is represented by a specific layer at natio
 nal scale and can be resolved by clicking to access the relevant area in a
 n OSM editor to modify the existing OSM data using the available imagery. 
 The most significant issues are displayed at all scales\, while minor ones
  are displayed at higher zoom levels.\nAll the issues can be processed by 
 a click giving access to a webpage providing mapping instructions and butt
 ons to open the area in either JOSM or iD. Forecasting next mapping steps 
 involving field mapping\, the OSM Skeleton approach also performs an analy
 sis of the completeness of points of interest (POIs) for cities and towns.
  \nInitially developed in two regions of Africa and South America\, the me
 thodology reveals regional or national patterns\, highlighting significant
  contrasts between regions and between small towns with the same region. D
 aily updated statistics categorized by issue or first-level administrative
  division provide a complete overview of the issues at hand. \nTechnically
 \, the OSM Skeleton approach uses standard PostgreSQL-generated Open Geosp
 atial Consortium (OGC) layers. These layers can be used on ready online ma
 ps provided by a spatial data infrastructure (SDI) or in any OGC-compatibl
 e client. All layers can be downloaded natively in various GIS formats. Ra
 ther than relying on remote mapping\, OSM Skeleton aims to expand local OS
 M activities\, including imagery and field mapping\, as well as the local 
 promotion of enhanced\, complete OSM data.
