GIS Database

General Information

Data format: ESRI Shape file (SHP), dBASE IV database (DBF)
Projection: Universal Transverse Mercator (UTM)
Datum: WGS-84
Zone : 48 North
Unit: Latitude/Longtitude (Lat/Long)

Ba Be – Na Hang dataset includes data for two provinces : Bac Kan and Tuyen Quang. There are three types of geographic data:

- Vector: All vector files are in ESRI Shape file format (SHP, DBF).
- Grid: Internal ArcGIS Grid file.
- Satellite image: Geo-TIFF format.

All vector files are transformed to Latitude/Longitude degree unit and attached with a pro-jection file (PRJ) in the same folder. The original data is projected to UTM projection, WGS-84 datum with following parameter.

All satellite images are aslo in UTM-Degree unit. Satellite images are Landsat TM (10/1994, 11/2000) with 20 m spatial resolution, 3 bands (1-2-3) true color composition. Each series includes 2 scence (path/row 127/44 and 127/45) covering the whole two provinces - Bac Kan and Tuyen Quang; ASTER image (2001) with spatial resolution 15 m covering the study area (Ba Be and Na Hang conservations); SPOT-5 (2.5 m spatial resolution) in natural color composite covering Ba Be and a part of Na Hang conservation area.

Biodiversity layers are prepared with support from Institute of Ecology and Biological Resources. Data has been updated to 2008.
