1 Definition of Global Map (by ISCGM) Definition of Global Map (by ISCGM) Global Map is a group of global geographic data sets of known and verified quality, with consistent specifications which will be open to the public, considered a common asset of mankind and distributed worldwide at marginal cost. Global Map is a group of global geographic data sets of known and verified quality, with consistent specifications which will be open to the public, considered a common asset of mankind and distributed worldwide at marginal cost.

3 Issues of Existing Global Data Sets Uncertain quality Uncertain quality Some data sets do not have clear quality information. Some data sets do not have clear quality information. Global inhomogeneity Global inhomogeneity Data quality is not globally homogenous. Data quality is not globally homogenous. Uncertain schedule for data revision Uncertain schedule for data revision No plan of updating data. No plan of updating data. Global Mapping Initiative through cooperation between national, regional and international organizations
