This guide to creating a dynamic GIS data model helps database managers design a schema that has comprehensive and descriptive query definitions, a user-friendly cartographic display, and increased performance standards. The five steps for taking a data model through its conceptual, logical, and physical phases, including modeling the user's view, defining objects and relationships, selecting geographic representations, matching geodatabase elements, and organizing the geodatabase structure are studied in detail. A look at nine decision points that deal with concerns common to all data modeling exercises, such as validating feature geometries, modeling linear networks, managing raster data, and labeling map features help database managers fine-tune their GIS data models. Several design models for a variety of applications are considered including addresses and locations, census units and boundaries, stream and river networks, and topography and the base map.

Designing Geodatabases for Transportation addresses the development of a GIS to manage data relating to the transportation facilities and service commonly organized around various modes of travel for accurate and reliable data exchange. Transportation involves several modes of travel, and although the details of each mode can be quite different, this book demonstrates how all follow a basic conceptual structure. That structure consists of an origin, a destination, a path between the two, and a conveyance that provides the ability to move along the path to establish a common data structure.

Locate your place in the exciting field of GIS In existence since 1962, Geographical Information Systems (GIS) arereally coming into their own today. And not just in your car's GPSsystem or your cell phone's tracking capabilities. GIS is findingapplications throughout science, government, business, andindustry, from regional and community planning, architecture, andtransportation to public health, crime mapping, and nationaldefense. Michael DeMers's Fundamentals of Geographic Information, FourthEdition brings an already essential text up to date, capturing thesignificant developments in the field and responding to the needsof a diverse set of readers, from geographers to students in a hostof other fields. If you are a non-geographer or new to GIS, get a quick introductionto the "lay of the land" of GIS through the new "Spatial Learner'sPermit" section. Then join in the excitement of discovery with GISdatabases as you absorb the such concepts and skills as digitalgeographic data and maps, GIS data models, spatial analysis,measurement and classification, cartographic modeling, and GISdesign. Responding to both the needs and technical skills of today'sstudents, this Fourth Edition: * Makes concepts accessible to students from a wide range ofbackgrounds * Offers more practical and relevant coverage of GIS design andimplementation * Reflects the latest changes in GIS applications * Examines in greater depth the underlying computer science behindGIS * Uncovers the most recent developments on GIS research * Expands coverage of the increasingly robust literature oncartographic visualization * Includes Web-based labs and links to current and updated datasetresources Taking an open-ended, hands-on approach that gets you to ask yourown questions about the underlying concepts, the Fourth Editionhelps you not only master the basics but acquire the activeproblem-solving skills that are a key component of success in theGIS industry.

Land parcel data (also known as cadastral data) provide geographically referenced information about the rights, interests, and ownership of land and are an important part of the financial, legal, and real estate systems of society. The data are used by governments to make decisions about land development, business activities, regulatory compliance, emergency response, and law enforcement. In 1980, a National Research Council book called for nationally integrated land parcel data, but despite major progress in the development of land parcel databases in many local jurisdictions, little progress has been made toward a national system. National Land Parcel Data looks at the current status of land parcel data in the United States. The book concludes that nationally integrated land parcel data is necessary, feasible, and affordable. It provides recommendations for establishing a practical framework for sustained intergovernmental coordination and funding required to overcome the remaining challenges and move forward.
