Dimension, abstract description.Network Three-dimensional electronic chart not only by intuitively geographical outdoor scene analog representation mode, provides the user ground
The map retrieval functions such as figure inquiry, trip navigation, while integrated living information, E-Government, ecommerce, virtual community, going out
A series of services such as row navigation.
Cache map：It is a kind of technology for realizing map fast browsing in browser, improves user to map
Browse speed.Map datum or picture are carried out cutting figure by cache map technology according to certain data rule, according to specific side
Formula carries out Qie Tu and storage.So user accesses map or picture can be with direct access data without on the server again
Generate, therefore cache map substantially increases display speed, improves the access efficiency of data.User is facilitated in network map
Browsed, inquired about etc. and being used.
Culture point of the same name：Refer to that two width have the image of the same area or the same position of map.
Cut figure rank：The rank of i.e. geographical caching, domestic geographical caching is 1-18 levels, cut per one-level figure engineer's scale and
The size of section has a specific standard, and the standard per one-level is different from but is all the general standard of a fixation, example
As geographical caching rank is higher, corresponding engineer's scale is bigger, and its section is less, the caching for being generated it is bigger, it is cut
The time that piece is consumed is longer, typically has the function of scaling to realize map, and the rank of the cache map for being used is usual
It is the geographical caching of continuous several ranks.

Match somebody with somebody, remote sensing image can be obtained by existing equipment, the present invention can directly using existing remote sensing image and three-dimensional artificial ground picture and text
Part is matched.Afterwards basis is cut graph parameter acquisition and cuts figure output directory file accordingly, is ultimately produced three-dimensional artificial map and is cut
Map file is issued.In S1, the coordinate system that remote sensing image is provided simultaneously with is WGS-84 plane coordinates systems.In S2, will
Preset format with quasi coordinates is defined as " pixel coordinate, geographical coordinate ", that is, first arranges pixel coordinate, rearranges geographical seat
Mark, centre is separated with comma, and each is write in that format in document with quasi coordinates, and preservation obtains registering coordinate file.In S3
Graph parameter is cut by user input, is generally comprised and is cut figure rank, pixel coverage and outgoing route.Figure program is cut for existing script
Code, directly runs.In S4, three-dimensional artificial map file is specifically loaded, to cut figure output directory file as output
Path output three-dimensional artificial map cuts map file.
S4 specifically includes following steps：
S41：Loading three-dimensional artificial map file, judges to whether there is white space in three-dimensional artificial map file, if so,
The then newly-built figure layer on three-dimensional artificial map file, and newly-built figure layer is filled to into white, by newly-built figure layer and three-dimensional artificial ground
Map file merges, and otherwise, directly performs S42；
S42：Start three-dimensional artificial and cut figure plug-in unit, paste the pixel coverage of three-dimensional artificial map file, and by outgoing route
