Modeling Our World is all about understanding the geodatabase, the collection of datasets that make a geographic information system (GIS) work. The book describes the key data modeling concepts of ArcGIS, a software product from Esri that is used for creaating and applying geographic information systems. To apply ArcGIS to its fullest, it's important to understand the fundamental concepts of the geodatabase. GIS data is organized as thematic layers that model real-world entities and are overlaid on a map. The data for these thematic layers is stored in the geodatabase as a collection of geographic datasets. Throughout this book, you will learn about the various geographic datasets that provide a rich foundation for modeling attributes, spatial and temporal relationships, imagery and terrain, editing transactions, and many display and analysis techniques. When you design and build geodatabase, you'll find many options for structuring geographic information. So that you can be successful in designing a geodatabase for your orgnization. //ir
