An AutoCAD client plugin is in net communication with a distribution service front-end processor, a background management system; a background service system is used for managing information of a whole application system, overall distributing all the data of the system and carrying out authority/application control and management; an image cutting tool is used for carrying out layering, vacuation and compression on a whole large image map by adopting a layer and pyramid superposition method, storing the image map according to a certain directory structure and then providing the image map for the background service system and the distribution service front-end processor to use. According to the network-based system for distributing image map data on AutoCAD software, the image map is cut in layers by adopting a tile pyramid; the background service management system is established; by adopting a network distribution technology, image data of a server side is called as required through a network according to the requirement of AutoCAD software data processing, and then is fused and projected to the AutoCAD software.
Description
Technical field
The present invention relates to AutoCAD software technology field, be specifically related to a kind of network photomap data dissemination system on AutoCAD software and method.
Background technology
Along with GIS(GIS-Geographic Information System) development of technology, increasing unit and part begin to use aerial images map, satellite photomap for the production of geodata and operation, and the department such as planning, territory also carries out the process of the surveying and mapping data such as topography, map-making parcel at a large amount of use AutoCAD softwares simultaneously.
Traditional aerial images map, satellite photomap are mainly used in cartography export and are supplied to user's online browse by website, are not carried out combining of photomap and the Survey data processing such as topography, map-making parcel.Survey data processing based on AutoCAD software job, is not carried out utilizing the achievements such as existing aerial images map, satellite photomap.
Existing photomap application mode on AutoCAD software is mainly: striograph map is carried out sectional drawing and saves as file, then the mode of file is inserted into AutoCAD software, as the reference of surveying and mapping data operation, file can not be crossed open network service and share, inefficiency simultaneously.
Traditional aerial images map, the satellite photomap mode using file on AutoCAD software, is managed not over network service and distributes, and uses the mode of file mainly to have following several shortcoming:
(1) management of versions of data, FileVersion confusion disunity it are not easy to.
(2) image data capacity is big, data sharing based on file and distribution, needs to transmit mass data, improves the use cost of data.
(3) the bad control of authority that data make, photomap file can replicate arbitrarily, propagate, and uses record disappearance.
(4) file inserts the speed of AutoCAD software, inefficiency, it is impossible to enough popularization and application on a large scale.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of network photomap data dissemination system on AutoCAD software and method.
In order to solve the problem existing for background technology, a kind of network photomap data of present invention dissemination system on AutoCAD software, it is made up of background service system, image cutting tool, distribution service front end processor, AutoCAD client plug-in；With TCP/IP, http protocol access communications network, AutoCAD client plug-in and distribution service front end processor, background management system connected network communication；The information of whole application system is managed by described background service system, plans as a whole all data of distribution system, and carries out authority, application controls and management；Described image cutting tool uses layering, the method for pyramid superposition, carry out photomap big for monoblock being layered, taking out dilute, compression process, it is divided into 256 pixels to remain the little image file with 256 pixels, and store according to certain bibliographic structure, it is provided that background service, distribution service front end processor use；Described distribution service front end processor is responsible for sharing of data and is controlled with distribution, distribution service is closed machine of putting and is received AutoCAD and the request of data of plug-in unit, by system background by real image data through pretreatment, pass to AutoCAD and plug-in unit uses, it is achieved image data is efficient, transparent transmission；Described AutoCAD client plug-in passes through user's operation to AutoCAD software, initiate the request of image data, the data transmission of the service front end processor of response distribution simultaneously, receives image data and goes forward side by side row-coordinate projection transform, merged with AutoCAD graph data by image data.
A kind of network photomap data distribution method on AutoCAD software, its method is: first pass through image cutting tool and image data is carried out pretreatment, carry out being layered and classification according to pyramid, take out dilute, compression etc. by image to process, raw video data are processed into the tile data of fixed pixel size, will store；User is initiated request of data by AutoCAD plug-in unit, after front end processor receives user's request, carried out signing power and record analysis by background service system, background image data are captured by front end processor after by, after transparent processing, pass to AutoCAD plug-in unit, AutoCAD plug-in unit carry out coordinate projection, conversion, it is achieved photomap fusion on AutoCAD software with represent.
As preferably, described background service system comprises data management, user's management, rights management.
Present invention have the beneficial effect that photomap is carried out layering segmentation by employing tile pyramid, set up background service management system, use net distribution technology, the on-demand image data by network call service end is needed according to what AutoCad software data processed, and fusion projects to AutoCAD software, the image data on backstage can be called real-time dynamicly, it is achieved the version management of image data, can by region image data conducted interviews control of authority, user uses the process of data record and manage.Solve sharing and distribution of massive image data, reduce the use cost of data.
