Spatial Data Acquisition and Integration

Abstract

The objective of spatial data acquisition and integration is to improve the logic and technology for capturing and integrating spatial data in the form of in situ measurements, census enumeration data, thematic maps, and products derived from remotely sensed imagery. This chapter identifies some of the major gaps or shortfalls in data integration and data collection strategies for more intensive investigation by University Consortium for Geographic Information Science and other scientists. It addresses important data integration issues that are generic to all data collection efforts. The chapter presents a brief investigation of current and potential in situ and remote sensing socioeconomic and biophysical data collection requirements. The relationship between the temporal and spatial data requirements for selected urban/suburban attributes and the temporal and spatial characteristics of selected remote sensing systems. Urban/suburban environments create great quantities of refuse, waste water, and sewage and require electrical power, natural gas, telephone service, and potable water.
