Preliminary experiences in preparation of GIS database of Terengganu state for the purpose of strategic agricultural planning and implementation

Ismail Abu Bakar, . and Zulkafli I., . (1998) Preliminary experiences in preparation of GIS database of Terengganu state for the purpose of strategic agricultural planning and implementation. [Proceedings Paper]

A GIS database for the state of Terengganu is being prepared. The database is intended to help the state decision makers formulate agricultural policy strategic planning and implementation. Requirements for spatial data were based on the states agricultural policy planning and implementation strategy statements as well as views from stake holders. Based on the objective of the database size of the state availability of spatial data and possibility of using satellite remote sensing data baseline information such as state/district boundary river network road system waterline etc. was developed from 1:50 000 scaled topographic map with district as the smallest processing unit. Spatial verifications of the baseline information using GPS-measured controlled points were found to be fairly accurate. Verification with Landsat TM images however showed some critical discrepancies. There were also some problems in the construction of the GIS database proper. Most obviously was a large variability in scales and sources of the input maps. Another problem encountered was shifting of the same feature from a different data souce.

Abstract

A GIS database for the state of Terengganu is being prepared. The database is intended to help the state decision makers formulate agricultural policy strategic planning and implementation. Requirements for spatial data were based on the states agricultural policy planning and implementation strategy statements as well as views from stake holders. Based on the objective of the database size of the state availability of spatial data and possibility of using satellite remote sensing data baseline information such as state/district boundary river network road system waterline etc. was developed from 1:50 000 scaled topographic map with district as the smallest processing unit. Spatial verifications of the baseline information using GPS-measured controlled points were found to be fairly accurate. Verification with Landsat TM images however showed some critical discrepancies. There were also some problems in the construction of the GIS database proper. Most obviously was a large variability in scales and sources of the input maps. Another problem encountered was shifting of the same feature from a different data souce.
