Abstract:
Forest and Land Cover Type, 1993 and 1997 (overlaid)
Forest types have been mapped with a high degree of detail.
Several major forest types have been differentiated.
Every major forest type has been sub-divided into density
classes, where appropriate.
Other (non-forest) land cover types have been mapped with
a lesser degree of detail, e.g. there is only 1 class of
permanent agriculture, which contains rice fields as well
as agricultural plantations. |
Metadata elements shown with blue text are defined in the International Organization for Standardization's (ISO) document 19115 Geographic Information - Metadata. Elements shown with green text are defined by ESRI and will be documented as extentions to the ISO 19115. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog.

AREA ------------------------- Lower Mekong Basin, including: - Cambodia (whole country, incl non-LMB part) - Laos (whole country, incl non-LMB part) - Thailand (LMB part) - Vietnam (LMB part) DESCRIPTION ------------------ Forest and Land Cover Types 1993 + 1997 (overlaid) Forest types have been mapped with a high degree of detail. Several major forest types have been differentiated. Every major forest type has been sub-divided into density classes, where appropriate.
