Graphic data processing method and system
First Claim
1. A method of processing data in different maps in order to display a designated region of interest for editing, said different maps carrying different kinds of information of an area, said area being the same area for each map, each map being sectioned into pages with boundaries between adjacent pages, comprising the steps of:
- establishing positional correspondence between said different maps;
storing data of said different maps into a file memory in the form of layers wherein each layer comprises the complete data of a different map and wherein each layer is sectioned into pages;
displaying on a display means a general map of said area, said general map includes information of said different maps;
designating a region of interest on said general map, said region of interest may include a plurality of pages for at least one of said different maps;
transferring data within said designated region of interest on said different maps stored in said file memory from said file memory to a temporary memory;
erasing said boundaries between each pair of adjacent pages in said temporary memory; and
displaying without boundaries a map of said designated region of interest on said display means for editing.

Abstract
A drawing processing system includes file storage equipment for storing drawing data in the form of pages through division of the drawing data, a memory for storing coordinate correcting values for managing pages in a continuated manner, and a temporary memory for storing page data for executing drawing edition processing. The drawing data are transferred from the file storage equipment to the temporary memory in a continuated manner, while the coordinate correcting values being added thereto. A joined drawing is prepared by combining together the pages along the boundaries thereof on the basis of the drawing data as transferred and by erasing the boundaries between the connected pages. Graphic edition processings such as displacement, joining, separation or the like can be then performed in the joined drawing.

11. A method of editing maps with the aid of file storage means for storing different maps carrying different kinds of information of an area, said area being the same area for each map, each map being arbitrarily sectioned into pages which constitute a continuous map when adjacent pages are connected, data for each map being stored on a page-by-page basis, correlation storage means for storing coordinate correcting values for rearranging said pages in a continuous manner, and temporary storage means for storing said data for executing editing processes of the maps, comprising the steps of:
-
transferring all map data of the pages successively from said file storage means, and said coordinate correcting values from said correlation storage means to said temporary storage means; obtaining a continuous map by joining together said pages along boundaries thereof on the basis of said map data and said coordinate correcting values transferred; and performing graphic editing processes including displacement, joining, and separation. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A drawing data managing system, comprising;
-
file storage means for storing data on different maps carrying different kinds of information of an area, said area being the same area for each map, each map having an arbitrary selected coordinate system and being sectioned into a plurality of numbered polygonal shaped pages which constitute a continuous map when adjacent pages are connected at boundaries between the pages, the data being stored on a page-by-page basis; temporary storage means for temporarily storing data of at least part of said maps to enable processing of said maps; processing unit means for executing processing on the data stored in said temporary storage means; storage means for storing data servicing for correlating identification number of each page with its page boundary polygon, relative rotation of the associated coordinate system and coordinate offset values represented in a standard coordinate system; means for extracting data of a first page of a first map from said extracted file storage means and transferring said data to said temporary storage means; means for extracting data of a second page of a second map located in said area to be at least partially overlapping on said first page of said first map and determining relative rotation and offset between coordinate systems of said first and second pages; and means for compensating the positions of data in said second page so that correspondence relation can be established between contents of said first and second pages. - View Dependent Claims (19, 20)

21. A drawing data management system, comprising:
-
file storage means for storing data of a plurality of maps carrying different kinds of information about an area, said area being the same for each map, each map being arbitrarily divided into sub-areas the data being stored on a sub-area-basis; input means for inputting map data to be stored in said file storage means; display means for displaying a map including map data retrieved from said file storage means; operation input means for inputting editorial processing of the map data; coordinate input means for designating coordinates in said map to be subjected to editorial processing; temporary storage means for temporarily storing drawing data to enable processing of the map data; processor unit means for executing the editorial processing at said coordinates designated by said coordinate input means; and means for displaying marks indicating availability of stored data for each of said sub-areas, in superposition on said map displayed by said display means. - View Dependent Claims (22, 23)

24. A drawing display system, comprising:
-
file storage means for storing data of different maps of an area, assigned with priority levels, the maps including maps carrying different kinds of information, each map being arbitrarily sectioned into a plurality of pages which would constitute a continuous map when adjacent pages are connected at boundaries; display means for displaying said data of said different maps; operation input means for inputting requests for the display of said data of different maps; temporary storage means for temporarily storing said data of said different maps to enable processing of the data of said maps; and processing unit means for executing the processing, wherein said maps are displayed on said display means in the order of said priority levels. - View Dependent Claims (25, 26)
