2. Some Barriers for China & US Studies
Theories
Methodology
Data
Technology 2

3. Why Geo-Spatial?
Data from different formats (polygon, line, point, image)
Data from different sources (population, business, environment, health, crime, education)
Data from different times (Census from different years with changes in boundaries)
Data and spatial analysis (neighborhood impact) 3

4. Why Online? Easy access Increasing data sources and sizes
Complex data structures
Tool updates
System compatibility
Confidentiality of data
Protection of property rights of data 4
