The generalized GIS technical requirements
Data Management and Integration
Biggest difference is that, with huge amounts of data more emphasis on data of multi-source heterogeneous and dynamic, and not just the data size. Even the small and medium-sized enterprises and the general public, in the era of ubiquitous computing, still has a big data requirements.

From Urban Computing To Social Computing
What Is Urban Computing ?

Urban Computing gather is sensors of city 、buildings、road net 、vechicles and residents are caculated as a unit ,synergy with the calculation process of city level.

The generalized GIS technical requirements
Under the joint efforts of Surveying, geography, computer science and other disciplines, after decades of development, the traditional GIS technology system has been more mature. However, ubiquitous geographic information appears on the GIS generalization put forward new technical requirements .
Generalized GIS
What is generalized GIS ?
Generalized GIS
Second: the broad geographic First: the treatment of generalized information systems, and geographic information system technical systems handle location-related information
Data acquisition and processing
Many types of generalized GIS facing the spatio-temporal data. The new demand for data collection technology including indoor map collection technology, true three-dimensional measurable multisource geographic information acquisition technology, mobile terminal positioning technology, the Internet contains the geographic information collection technology

This is a 64GB micro SD card. It weighs about 4/10 of 1 gram, and costs about $53.
Real-time monitoring of the natural environment, social environment and scan increasingly diverse“ Data is growing at an alarming rate in the Pan Geographic Information Age。 Therefore, the concept of pangeographic information age also need to generalization, generalized GIS emerged
What Is Social Computing ?

social computing is computing theory or a methods about social activies, socia process, social structure,social organization and social function.

The Era Of Big Data
The emergence of Big Data made the geo-computing becoming popular, the Clound computing and Common computing rise the scale of Geo-computing 、accuracy and efficiency,at the same time,also promoted the integration of urban computing and social computing.
Social
computing aims to study the running rule and the trend of development of social system with the tech of computing, and help people to communicate and collaborate better.
The Era Of Big Data

The generalized GIS technical requirements
Data analysis and calculation
General GIS in terms of data analysis and calculation from multi-factor spatial and temporal correlation, based on the location of the mass of moving objects trajectory analysis, the characteristics of complex network geographic space, and other aspects. Strengthen the theoretical research in the field of artificial intelligence, machine learning, technology research and development, enrich general GIS analysis ability.
Under Generalized GIS
Although
the urban computing and social computing are complex , but from oriented geospatial calculations to compute the city scene, and even the whole of society is calculated , it can be expected that geo-computing and urban computing will integration better , and services for modern society’s Management and people’s life.
