5.1 Introduction

Every user of geospatial data has experienced the challenge of obtaining, organizing, storing, sharing, and visualizing their data. The variety of formats and data structures and the disparate quality of geospatial data can result in a dizzying accumulation of useful and useless pieces of spatially explicit information that must be poked, prodded, and wrangled into a single, unified dataset. This chapter addresses the fundamental concerns related to data acquisition and management of geospatial data’s various formats and qualities currently available in modern geographic information system (GIS) projects.
