Questions raised:

1. Data Synchronization (GIS and business)

1) store data only on one side (GIS or business) as much as possible, especially on the relationship between devices. GIS can simulate the relationship between storage devices, and provide good graph query algorithm tools, some NoSQL and other databases (such as graph-oriented database neo4j) also provide good graph storage and query algorithm tools. When you add and remove devices to the relationship between storage devices in a GIS, you need to rebuild the relationship between devices, which is more advantageous in storing the relationships between devices in the database.

2) When data is stored on both sides, the GIS updates the map and calls the business interface to update the resources, and updates the map data (including the rebuilding of the map feature topology) after updating the resource.

2. Topology diagram to build with ArcGIS schematic tools

ArcGIS schematic does not provide a rest interface in the current radio and TV ArcGIS Server 10.0, it can only be generated and published using the GP service, and there may be a problem interacting with the map for the topology diagram. This remains to be studied.

3. Visual editing of resources

This function is mainly to handle the connection information between the ports of each device. In fact, the relationship with GIS is not strong, do not need to use ArcMap to complete (too professional and cumbersome), you can directly use Flex to develop a resource editor or based on third-party components (such as springgraph and flowchart, etc.), and save the results of the edits to the database.

4. Intranet map opens very quickly, the outside network map opens very slowly

The main reason is that the amount of map data is relatively large. There are several ways to reduce map data transfer:

1) When using the map, minimize the use of featurelayer and try to place the layers used in a map service.

2) for layers and map services that are not currently operational, try not to display them, and then open the corresponding layer when the user needs to do a map operation.

3) The symbols of the map elements are as simple as possible and do not use compound symbols.

Recommendation:

First, business content aspects

1. Alerts can include a few more features, such as the following:

1) Dispatch inspection and repair, as well as feedback, the worker's driving directions, etc., on the map to bring up the business Operation page, or show the results of the operation on the map.

2) Add equipment statistics and evaluation, you can obtain the quality of equipment, equipment replacement.

3) Evaluation of the dispatched workers.

2. Further relates the device to human

1) Query the device will affect which users (that is, who shared the device).

2) Analyze the user's changes and display them on the map.

3) Which of the equipment in the engine room is the person to manage.

3. Path Analysis function

1) The best driving route analysis of the dispatched workers.

2) Real-time tracking (GPS) display and historical track search for dispatched workers, as follows:

4. Route planning

1) on the map automatically calculated (hand-drawn) out of the planning line, calculate the length of the cable, and then estimate the cost of the line.

Second, GIS aspects of the function realization method

1.Jifang/jifangredian and Jifang/jifangtupian use too many layers, with thousands of them. It is suggested that this function should not be stored by GIS, but stored by the database and displayed by dynamic loading by using the drawing function of flex itself.

2. The alarm of the computer room full map refresh. It is recommended that only graphics that have the alert status changed be refreshed.

3. It is recommended to make a navigation tree for the relationship between key equipment to facilitate the user to quickly locate (for example: small and medium-sized computer room-sub-front-optical receiver-users)

4. It is recommended to reduce the use of featurelayer, instead of using MapServer to improve map speed.

5. It is recommended that analysis algorithms such as Link analysis, network topology, pipeline connectivity analysis, routing assistance planning, and capacity analysis be made into an SOE of ArcGIS Server and released into ArcGIS services.

6. It is recommended to add line and polygon buffer analysis in map buffer analysis, which is advantageous to the number of meters in the optical fiber cable and cell area of the facilities

7. For details that do not interact with the map, you can directly display the business-ready page, including the video display.
