Introduction

Strategi is a regionally based dataset useful for activities such as decision making in planning. It is a geometrically structured 1:250,000 scale vector database that defines the real world geographic entities (objects) as point and line features. Each feature consists of geometric and attribute data. Coordinate resolution is 1 metre.
