z National Digital Elevation Modelz National Current Vegetation Map
z National Soil Map
z Regional General Circulation Model
AIM /Korea Team5

IV. AIM/Korea Impact Modelz National Landcover Classification Map- Raw Data : Landsat TM- Methods- Classify the land cover into 7 categories
by a combination of unsupervised andsupervised classification methods
using Landsat TM satellite data
- The 7 classification categories are:
Built-up area, forest, agricultural area,grassland, barren land, wetland, and water- The classification accuracy isestimated to be 75% to 85% maintaining
30-meter ground resolution
AIM /Korea Team6

IV. AIM/Korea Impact Modelz National Digital Elevation Model- Raw Data : 1:50,000 Scale Contour- Methods- Derived from the contour layerof 1:50,000 standard topographic
digital map- Grid size is 30m

AIM /Korea Team7

IV. AIM/Korea Impact Modelz National Current Vegetation Map- Raw Data : Korean Actual Vegetation Map
produced by the Ministry of Environment,
Korea- Methods- Digitalized the 1:50,000 scale National ActualVegetation Map produced by the Korean
Ministry of Environment to GIS format- Vegetation community level classification
by ground truth survey- 1:50,000 scale National GIS Database Project andcurrently updating the records- Representing 229 vegetation communities

AIM /Korea Team8

IV. AIM/Korea Impact Modelz National Soil Map- Raw Data : National Soil Map produced by National
Institute of Agricultural Science and Technology (NIAST)- Methods- Classification based on the soil's physicalcharacteristics- Field capacity is calculated with soil texture,soil depth, and water content percentage- Expected to be completed by the end of 2000

AIM /Korea Team9

IV. AIM/Korea Impact Modelz Regional General Circulation Model- Raw Data : GCM Data produced byMeteorological research Institute(METRI)- Methods- Physical model using general circulation
model(GCM) based on the boundary
condition- Used as the atmospheric inputs to run
METRI-meso Realtime Forecast Model- Grid size is 60Km

IV. AIM/Korea Impact Model
2. Comparison of Results;
Assessment of Impact on Korea's Water
Resourcesz AIM/Korean IMPACT model has been reprogramedby FORTRAN to enhance the data compatibilityz Climate Data and Information Basis- Input data is interpolated into 0.1 degree grid with 50 pixels
in column and 60 pixels in row.
- 1-degree field capacity data is resampled to 0.1-degree grid data
- The surface runoff under current climate is validated with amodeldeveloped by Korea Research Institute for Human Settlements
