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. |

- 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.
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

SOURCE MAP -------------------
Satellite Image Hardcopies were originally georeferenced to:
Cambodia:
- 1:50,000 scale topographic maps, UTM Zone 48, US series L7016 (1960s/70s)
Laos:
- 1:100,000 scale topographic maps, Gauss Zones 17 + 18, Russian series (1980s)
Thailand:
- 1:50,000 scale topographic maps, UTM Zone 47 + 48, based on US series L7016 (1960/70s)
Vietnam:
- 1:50,000 scale topographic maps, UTM Zone 48, based on US series L7016 (1960/70s)
SOURCE DATA SET --------------
Landsat TM Satellite Image Hardcopies (Photographic Reproductions)

years 1992/93 (1st interpretation)
years 1996/97 (2nd interpretation / monitoring)
not geo-referenced

STATUS -----------------------
Last update: Jan 1999
Completion status: 100 %
COMMENTS ---------------------
minimum mapping unit: 4 * 4 mm at map scale (equiv 1000 * 1000 m)
in areas of cloud cover, interpretation results from an identical
visual interpretation of 1993 satellite imagery were inserted
(effecting 0.6 % of the entire coverage area)
data originally referenced to UTM Zone 47 and Gauss Zones 17 + 18
were re-projected to UTM Zone 48
data set has been clipped with the OLD (1:250,000 scale)
Lower Mekong Basin (LMB) boundary (except for Cambodian and Lao
non-LMB parts)
neighbouring polygons with identical attributes have NOT been
dissolved in order to keep polygon sizes reasonably small
