GIS System |
From a systematic point of view, GIS is a computer system for collecting, storing, managing, querying, analyzing, and expressing and displaying geographic information. It is also a general technology for analyzing and processing massive geographic data.
GIS regards the entire earth space as an object, records and stores the real world of things, symbols as data, process the data into information. Through spatial analysis, geographic data processing and other professional methods, GIS extracts useful knowledge from information, and finally through the analysis of auxiliary decision-making, get conclusion from the extracted knowledge, i.e., wisdom.
The cloud GIS applies the cloud computing technology to the GIS system to support the collection, storage, display, modeling, processing, analysis, etc. of geographic information, which brings a more friendly, more efficient, and lower cost of geographic information resources.
Due to the particularity of GIS data and services, in the use of GIS services, in addition to attention to GIS cloud services, we often need to focus on different scenarios under the specific GIS clients. If the party that provides the GIS cloud service is called the "GIS cloud", the party that uses the service can be called "GIS terminal". This is the two main bodies in the cloud and terminal integration GIS. But only the two main bodied are not enough, because the interaction between GIS terminals and GIS cloud has some complexity. Therefore, we should also pay attention to interaction between GIS cloud and GIS terminals, that is, integration of GIS technology. Therefore, the Cloud & Terminal Integration GIS technology system consists of three components: GIS cloud technology, GIS terminal technology and integrated GIS technology. The three aspects of technology is to achieve Cloud & Terminal Integration of three parts for the GIS system: intensive GIS cloud platform , a variety of GIS clients and integrated GIS system.
Based on the Cloud & Terminal Integration GIS technology system, SuperMap GIS 11i(2024) provides a powerful cloud GIS portal platform, cloud GIS application server, cloud GIS distribution server, and a wealth of mobile, Web, PC client products and development kits, which helps customers build a GIS system with powerful cloud & terminals, mutual benefit, safety, stability, flexibility and reliability.
Based on the Cloud & Terminal Integration GIS technology system, SuperMap GIS 11i(2024) provides a powerful cloud GIS portal software platform, server GIS software platform, GIS edge software platform, and a wealth of mobile, Web, PC client products and development kits. With complete GIS software from cloud to clients, SuperMap GIS 11i(2024) helps customers build a GIS system with powerful cloud and clients, mutual benefit, safety, stability, flexibility and reliability.
Specifically, the powerful cloud GIS platform is built quickly through the GIS cloud manager iManager, the cloud GIS portal software platform iPortal, the server GIS software platform iServer, and GIS edge software platform iEdge. With multiple terminals of iMobile, iClient, iDesktop, iObjects, SuperMap GIS 11i(2024) helps to build a variety of cross-platform client applications, to connect to GIS service platform and SuperMap cloud service in a variety of devices. Multiple terminal application can use GIS data and services in cloud GIS platform, display geographic information in multiple terminals, and collect, produce and upload data to cloud platform.
Taking the process of GIS data processing as an example, in the Cloud & Terminal Integration application, the software from cloud to clients are involved in the data acquisition, processing, storage, analysis, distribution. The software of each platform has its own advantages, and performs their correct role in a complete GIS system.
As can be seen from the following figure, terminal applications on a variety of devices can be used for data collection and processing, and no longer limited to desktop applications. In addition, the data flow is no longer terminated with the result output of the analysis. The output can also be distributed and shared between multiple users and multiple devices, and can be further used by other users. The entire data flow is no longer from the input to the output of the static process, but can be updated by other users to share the dynamic process at any time. Therefore, in the current GIS applications, multi-device, close to the user's mobile applications broadens the GIS data sources, and broadens the applications of GIS scenarios. The entire data flow is more open.
