  1. GeographicInformationSystems UsingESRI ArcGIS 9.3 INTRODUCTION

  2. GIS = Geographic Information System= a software package aimedto import, store, handle, edit, view, query, analyse and printgeographic information INTRODUCTION

  3. DATA STRUCTURES Vector Raster Table INTRODUCTION

  4. DATA STRUCTURES: Vector Precise butcomplicated Points Polylines Polygons INTRODUCTION

  5. DATA STRUCTURES: Vector Precise butcomplicated Points Polylines Polygons INTRODUCTION

  6. DATA STRUCTURES: Vector Precise butcomplicated Points Polylines Polygons INTRODUCTION

  7. DATA STRUCTURES: Raster Easy tohandlebut low precision INTRODUCTION

  8. DATA STRUCTURES: Tables Ancillary information with no georeference (no coordinates) INTRODUCTION

  9. GEOREFERENCE INTRODUCTION Coordinates (X, Y or Lat, Lon) + Coordinate System (Geographic / Projected, Method, Geodeticparameters) Everygeographicobject (point, polyline, polygon or raster) ischaracterizedbyits position on the Earth’s surface
