Research On Environment Of Digital Statistical Map Based On MapInfo

In our economical construction and management practice, people cannot find the underlying laws in data that are stored in DBMS in form of tables. Though current GIS software can provide the fabrication of thematic maps, just as Maplnfo, ArcView, MapGIS and so on, the main disadvantages existed in these software are that they cannot judge the distributing character of data before fabricating thematic maps. As a result, consumers of GIS cannot choose right method of classification for these data, and it is difficult to discover the laws hiding in them, and the number of classification in current software is so small that it cannot satisfy the more and more different needs of users . The environment mentioned in this article aims at boosting the practicality of statistical map because it integrates the comparably matured statistical software SPSS, automatic vectoring software R2V, in order to advance practicability of maps. One of the important contents of this thesis is the environment can provide more methods of classification and judge the character of data before choosing the classification method.At present, SPSS is a software with formidable functions, including various of data disposal and fabrication of graph; R2V can integrate the intelligent digital vectoring technology and the simple menu interface into Windows, it also provides the interchange from raster data to vector data, the results of vectoring can be directed into Maplnfo; MapBasic is an unearthly programme language based on Maplnfo, and it bears the function of interviewing database, provides structure of exploitation, transfers DLL compiled by Windows or C language.The author starts with the problems existing in data visualization and exerts on different functions and advantages of current software. The environment carries second development using MapBasic, and it handles different software in Maplnfo, can provide abundant functions of thematic map fabrication, more detailed help menus so that users who are not familiar with the environment can operate it. Automated vectoring software R2V replaces Maplnfo; judges the characteristic of data using SPSS; simplifies some functions of Maplnfo by way of menu interface; the connection of space data andattribute data becomes simple; extends the function of Maplnfo by perfecting classification methods using MapBasic.This thesis tries to innovate in several aspects:1) The environment integrates the current classification methods and mathematical statistical software, automated vectoring software R2V into GIS. It at first judges the characteristic of data before selecting classification method, and users can choose right method so they can find the underlying rules. The whole environment is operated in Maplnfo so that users can master it easily;2) The environment provides more classification methods so that users have more selection, and this function makes up the flaws of current software;3) The environment provides favorable user interface and detailed help menu so that users who are not familiar with the environment can operate it easily and can tailor scientific, handsome maps;4) The environment designs normal classification template so that users can compare results of their own with it, as a result, the precision of classification is boosted.
