This article mainly introduces what mapinfo refers to, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

MapInfo is a desktop map information system software with powerful function and easy operation, it is a desktop solution of data visualization and information mapping, it has basic operations such as input and editing of graphics, query and display of graphics, database operation, spatial analysis and output of graphics.

MapInfo is the desktop geographic information system software of MapInfo Company in the United States, which is a desktop solution of data visualization and information mapping. According to the concept of map and its application, it adopts the operation of office automation, integrates a variety of database data, integrates computer map methods, uses geographic database technology, and adds the analysis function of geographic information system. it has formed a popular small software system with great practical value and can be used by various industries.

MapInfo means "Mapping + Information", that is, map object + attribute data.

Function introduction

MapInfo is a powerful and easy-to-operate desktop map information system. It has basic operations such as input and editing of graphics, query and display of graphics, database operation, spatial analysis and output of graphics.

The system uses menu-driven graphical user interface to provide users with five kinds of tool bars (main tool bar, drawing tool bar, common tool bar, ODBC tool bar and MapBasic tool bar).

The user enters the conversation state through the command on the menu bar or the ammonium button on the toolbar. The viewing table windows provided by the system are: map window, browsing window, statistics window, and layout window that helps to output the design, and the output results can be easily output to the printer or plotter.

Input of graphics

The input of graphics is to digitize or convert all kinds of map information data in order to obtain the basic graphic data organization of MapInfo-tables. Depending on the data source, you can use hand-held digitizer, scanner input or other standard data format to transfer. Such as AutoCAD (.DXF and .DWG), Intergraph (.DGN), ESRI ArcView Shape data and so on.

Data table management

In MapInfo, a database is called a table, and two tables can be used to create, store, query, and display attribute data. One is a data table, which can be divided into a data table containing graphic (map) objects and a data table that does not contain graphic objects, such as a spreadsheet or an external data table; the other is a raster table, which is an image that can only be displayed in the map window. there is no table structure such as records, fields and indexes of data tables. Here we only discuss the operation of the data table.

Query function

MapInfo system provides users with powerful and flexible query function, which is called Selection function in the system. Through the selection, we can not only query the information of the corresponding data table directly from the map, but also use the SQL Selection provided by the system to look up the corresponding data and map information from the data table. The system uses a temporary table (Selection table) to store the selected results, for the temporary table can also perform many operations for the basic table, such as browsing, statistics, copying or editing the table, and can further generate a new Selection.

Secondary development language

MapBasic

MapBasic is the secondary development language of Mapinfo. It is an interpretive language similar to Basic. The * .mbx file generated by MapBasic programming can run on the Mapinfo Professional software platform. The early secondary development of Mapinfo is based on MapBasic.

Mapxtreme

Mapxtreme is a secondary development kit (SDK) provided by MapInfo, which is based on object-oriented and provides COM loading. It can be developed in development languages and environments such as VB,Delphi,C++,.net,java.
