Combining data from multiple sources

Introduction

A GIS project usually involves multiple data sets, so this step addresses the issue of how these multiple sets relate to each other. The data sets may be of the same area but differ in accuracy, or they may be of adjacent areas, having been merged into a single data set, or the data sets may be of the same or adjacent areas but are referenced in different coordinate systems.
