Abstract
The invention discloses an automatic map cache service updating method. The method includes setting an automatic map cache service updating identity, managing identity information, and recording corresponding service information; defining a map updating process; establishing an updating range and an updating grade of cache updating of this time in a map cache updating task; judging whether a map starts automatic cache updating or not; building a map cache updating scheme template; creating a map cache updating tool; utilizing the cache updating tool to read the cache updating template to form a new cache scheme; after updating of updating data is completed, adding the updating range and the updating grade which are acquired into the map cache updating tool in a cache task mode to trigger execution of map cache updating. The automatic map cache service updating method has the advantages that cache updating schemes are stored in a template mode, so that convenience is brought to a user for secondary modification; a mode of map cache updating is automatic triggering, and manual intervention is not needed, so that cache updating efficiency is improved.
Description
Technical field
The present invention relates to cache map technical field, in particular to a kind of cache map service automatic update method.
Background technology
Along with the development of network technology, Geographic Information System (WebGIS) application in network environment is more and more extensive, and the Google Maps in such as daily life, MapBar map etc. all extensively affect the life of the public.With traditional WebGIS mode in the past unlike, these Modern Maps no longer dynamically generate map picture in client, and (namely client often produces once new such map requests, server just need regenerate map picture and be sent to client), but have employed cache map service mechanism.After GoogleMap releases Tile Map Image (tile type map) mode, this cache map service mechanism just becomes the gordian technique improving map application system performance.In cache map technology, network transport cost and database access cost are the principal elements of influential system efficiency always.Jpeg format, with the image quality of its superpower compressed capability and brilliance, is widely used in cache map service mechanism.
In the past because Data Update is slow, the renewal of cache map data was also very slow, thus caused cache map to upgrade edge implementation by hand always.Now, along with the high development of economic society, people become more and more urgent to the demand data upgraded fast, and this cache map update mode by realizing by hand just becomes a large bottleneck, and are badly in need of being broken through.Such as: the buffer update mode of MapGIS, the buffer update of global map can only be realized and (use 1:500 engineer's scale, the more New Testament of city's DBMS needs the time) cannot be defined the scope of Data Update; The buffer update mode of ArcGIS, can realize local map buffer update, but needs manually to define more new range and rank, and this it is also proposed higher requirement to the quality of operating personnel.
According to the map the update mode of buffer service and renewal realize principle, upgrade from Data Update to service, manually-operated performing step is as follows:
Obtain the scope of Data Update;
Search the service to be updated more corresponding to new data;
Manually choose the service needing to upgrade, more new range and Update Level are set in buffer update scheme;
Temporary transient stopping externally providing service.
For above 4 steps, there are some manufacturers that the buffer service of subrange can be provided to upgrade other manufacturers and then can not; When arranging body of a map or chart, adopt manual type that scope is set just not as adopting the automatic computer capacity of computing machine accurate; When service contextual data, manual operation also easily makes mistakes.
Based on above reason, increasing domestic manufacturers come to realise the importance of the automatic update service of buffer memory, part domestic manufacturers have taken up research buffer service automatically updating function, but the Data Update be limited by the past and the medelling of flow chart of data processing, also there is certain limitation in the flow process of its automatic buffer update.And foreign vendor, especially some platform provider, its foothold is still placed on abroad, is not fully recognized that the actual demand that Chinese market is strong, still carries out cache map renewal in employing manual type.
Summary of the invention
For solving the problem, the object of the present invention is to provide a kind of cache map update method of automatic buffer memory.
The invention provides a kind of cache map service automatic update method, it is characterized in that, comprise the following steps:
Step 1, arranges the automatic more new logo of Map Services when Map Services is issued, manage the identification information of described automatic more new logo, in described identification information, record corresponding information on services;
Step 2, the flow process of definition map rejuvenation, comprises three steps,
Step 201, definition checks out scheme: each scheme that checks out is exactly a more new task, in the described layer checking out definition in scheme and need to check out;
Step 202, scheme checks out: arrange and check out scope, and the described data checked out in scope are checked out temporary library, and the data of described temporary library supply operating personnel outside to modify and upgrade, and lock to the described data checked out in scope simultaneously;
Step 203, scheme logs on: check out scheme and the data needing to log on described in selection, the data logged on described in comparison and original data, arrange mapping relations to the described data that log on and described original data simultaneously, by the described data inputting logged on in the layer needing to log on;
Step 3, according to topology inspection, the situation of change of the data logged on described in judgement and described raw data, obtains map rejuvenation scope, more new data, builds the cache map more this time more new range of buffer update and Update Level in new task;
Step 4, serve according to the map whether arrange described automatically more new logo and the described more new range obtained, described Update Level judge whether map starts buffer memory and automatically upgrade, if then carry out step 5, otherwise do not start buffer memory and automatically upgrade;
Step 5, if issued cache map service or arranged default scheme template, carry out step 6, otherwise built cache map update scheme template;
Step 6, builds cache map more new tool;
Step 7, utilizes described buffer update instrument to read described buffer update plan template, and more new range and described Update Level described in arranging, form new buffering scheme;
Step 8, after described renewal Data Update completes, the described more new range obtained and described Update Level, add described cache map to more in new tool in the mode of buffer memory task, triggers the execution that described cache map upgrades.
Further improve as the present invention, the content database of the task of buffer memory described in step 8 stores.
Further improve as the present invention, described cache map more new tool is monitored described database.
Beneficial effect of the present invention is:
1, the templating of buffer update scheme: the update scheme of buffer memory all stores in the mode of template, is convenient to the second revision of user.If different services uses identical update scheme, the template that direct use has stored.
2, cache map service upgrades triggering automatically: the mode that cache map upgrades, by manual activation in the past, becomes automatic triggering, and the renewal that cache map is served and Data Update harmoniously, do not need manual intervention.The acquisition of Data Update scope, and specified level upgrades the rank automatically being calculated scope and the renewal at every turn upgraded by program, makes each content upgraded become more accurate, thus significantly solves the time of buffer update, the efficiency of raising buffer update.
