Get an international perspective on the latest issues relating to spatial analysis, accuracy in the location and special representation of data and real world features, and emerging standards for digital spatial methods and applications. Twelve peer-reviewed papers cover:
Accuracy and Uncertainty in Spatial Data and Analysis
Application of krieging and other geostatistical techniques
Fractal analysis for spatial applications
Difficulty in defining the level of accuracy for environmental and hydrologic data
Spatial variability, uncertainty, and risk for use in decision support systems
Use and application of global positioning systems (GPS)
Modeling and Spatial Analysis of Environmental and Hydrologic Systems in Spatial Data Environments
Spatial techniques to model environmental systems
Development of object models for hydrologic systems.
Development of a flood warning system for watersheds in Spain
Modeling the distribution of soil moisture with remote sensing and geographic information systems (GIS)
Data integration with GIS as a management tool for decision support
Efforts to model surface soil moisture from satellite microwave observations
Use of response units to assess erosion processes in semiarid areas in southern Africa
Standardization and Standard Digital Data Sets
Methods, descriptions, and digital data products, such as the watershed boundary standards for the U.S.
Status of standards in use by the U.S. government related to GIS data
Role of other organizations in the development of standards for GIS
Development of standard merged products of satellite imagery and elevation data for natural resource mapping in Canada
Development of a series of standard digital databases, in which U.S. Geological Survey has been particularly active
This publication is based on a symposium sponsored by ASTM International in cooperation with the International Commission on Remote Sensing of the International Association of Hydrologic Sciences, the Canada Centre for Remote Sensing, the U. S. Geological Survey, and the U.S. Bureau of Reclamation.
