  1. you can experience the online demo of SuperMap iServer: http://www.supermap.com/en/html/SuperMap_GIS_OnlineDemo.html
  2. yes, in China, SuperMap GIS and ESRI are competitors, and last year, in Chinese GIS market share report, SuperMap occupies 32%, ESRI occupies 29%.
  3. GIS software is good for the functions like data conversion, data processing, analyzing, 2D & 3D mapping, layout designing, map publishing, etc. But GIS software is not as easy to operate as other daily-use software. SuperMap GIS has unified codes for all products with many features such as cross-platform, 2D & 3D integration, cloud and terminal GIS integration, etc. Therefore, in this article, we give an example using SuperMap GIS, in where you can find the training tutorials on Youtube or even download from SuperMap GIS website. http://www.supermap.com/en/html/SuperMap_GIS_OnlineVideo.html Or you can download SuperMap GIS training slides to have a more comprehensive understanding of operating SuperMap GIS software. http://www.supermap.com/en/html/SuperMap_GIS_TrainingSlides.html Don’t forget to download SuperMap GIS software(with 3-month free trial included) http://www.supermap.com/en/html/SuperMap_GIS_ProductPackages.html Software GIS operation videos on YouTube : https://www.youtube.com/channel/UCA4K8YXKTVxoz6dDW0nMGxg

  5. 1 Forestry GIS for forest protection Geographic information is highly important for forest workers. ‘High precision positioning portable device for forestry GIS ’ is developed based on SuperMap iMobile for Android, applying for Android devices with GPS functions. There are necessary modules like high-resolution aerial images, GIS positioning, trajectory, destination information generation, forestry registration query, distance measurement, photograph taking, etc. Meanwhile, the system also contains the land layer, which can compare the land attributes and forestry log information, linking the land shape data and GPS locations. ‘Forestry GIS’ also can interact with forestry GIS windows version, realizing information sharing. This system has been given Japan electronic land award. Local government, forestry companies can use portable device to investigate boundaries, acquiring the information of the owner of forestry, setting forestry path, making the cutting plan. Boundaries investigation: Use high-resolution aerial image data and GPS coordinates to locate. Forestry information acquirement: Query forestry information according to the current location, query the owners of the forest and label with color, making the circumstances under control. The local governments which have provided land data can distinguish the owner of the form and boundaries, so that they can know the differences of boundaries and registered forestry, registered land. Setting forestry path, making the cutting plan: To plan forestry path, GIS trajectory is very useful. It will take the photo when meeting obstacles, recording the image and location information for the future use. 2 System Application Category After the development of forestry GIS, there are more business like radiation measurement, UAV photogrammetry like Radiation, UAV forestry investigation, forestry repair. 2.1 Forestry Pest Monitoring In the forestry area along Japan Sea, there are serious pest problems in pines, which needs checking the pest status from helicopters time after time. If the anomaly has been found, the scientists from institute of forestry science will bring the forestry GIS to collect data on site. 2.2 Radioactivity Investigation The local mushroom has been influenced by the radiation of Fukushima nuclear accident, using the radioactivity density monitoring devices linking with potable forestry GIS, it is easy to get the radiation distribution. Portable forestry GIS has become a necessary tool for the forestry experts. 2.3 Forestry investigation and GPS In Aomori, Japan, there are more than over 90% of area with cadastral information, and 100% for forestry area. Therefore, the boundaries of forestry can include the results of cadastral information. However, the accuracy of forestry cadastral investigation is low, there might be the situations of the differences of registered forest boundaries, whose errors may be meters even tens of meters. Forestry companies know the accuracy of mountain data is low, so they will use different GPS devices when acquiring the location information. The errors range should be within 150-300cm according to Japan Land Investigation law, most GPS can meet this requirement. During the process of developing forestry GIS, in order to tackle the problem of low accuracy of mountain areas, we have tested the measured coordinates of GPS, and added automatic calculation in the system to display the location accuracy.

  11. Better performance, better service SuperMap iServer 8C(2017) has made great improvement on service performance, not only the service usability of GIS service multiple instance has been improved, but also better service can be provided by constructing front processor. Meanwhile, the new service dispatch extension module provided by SuperMap iServer 8C(2017) allows easier connection with third-party platform. Vector styles of map give better viewing effects. GIS service supports multiple instance: more reliable, more effective Based on micro-service architecture, SuperMap iServer 8C(2017) supports activating multiple instances on GIS service. After activation of multiple instance, SuperMap iServer 8C(2017) will divide multiple service instances, every service instance occupies one isolated process (independent port), and services are mutually isolated and provide complete GIS functions to respond service requests. For example, for map-China/rest service requests, in the single instance mode, system only has one port with name 8090 to respond. After activating 3 instances, there are instances with port name of 8091, 8092, 8093 to respond the service requests. Therefore, when there are requests of high-parallel situations, multiple instance can improve service quality. Meanwhile, the instances have mutual backup copies, when one of these has malfunction, the request will be transferred to other instance to ensure the usability of service. Before activation of multiple instances in GIS service- waiting in queue After activation of GIS multiple instances in service – parallel response to request In addition, with the concept of heterogeneous service of micro architecture, service instance can also be heterogeneous. In a simple way, there are different service contents in different instance. Like the instances of port 8091 and 8092 provides map-china/rest service while port 8093 provides map-world/rest service. Heterogeneous service instance means unequal of service instance, so the users can decide service instance number according to different service loading to maximize the utilization of hardware. Heterogeneous service instance iClient polling mechanism helps to construct better GIS application system SuperMap iClient 8C(2017) for JavaScript has new polling mechanism. If you have already deployed multiple GIS servers, when processing user map service requests, SuperMap iClient will dispatch these responses to different servers, making servers process the requests to speed up user access speed; for query services, SuperMap iClient can request on servers, if the target server is not available, it will skip the server and then send to other servers till get response, which greatly improved the service usability. iServer + iExpress + iCLient combination of front processor to improve system performance In the front processor solution, SuperMap iExpress as the front processor of the client, processes requests on client through service agent, cache, technologies. This avoids direct interaction between client and GIS service center, making secure isolation of GIS service center. Furthermore, if you deploy multiple SuperMap iExpress and combine with SuperMap iClient polling mechanism, it avoids single-point failure to ensure the usability. Front processor diagram
