Mapping related software usage experience

I am a surveying and mapping engineering undergraduates, has been studying in school for more than two years, also contacted some related mapping software, such as Autocad,cass,matlab,cosa, also use them for certain use.

AutoCAD has the basic functions of plane drawing, drawing aids, editing graphics, dimension, writing, layer management, three-dimensional drawing, network function, data exchange, etc., with interactive technology. Graphic transformation Technology, surface modeling and solid modeling technology. Mainly used in engineering drawings (construction, decoration design, environmental art design, hydroelectric engineering, civil construction, etc.), industrial drawings (precision parts, molds, equipment, etc.), garment processing (clothing plate), electronic industry (printed circuit board design), and widely used in civil construction, decoration and decoration, urban planning, landscape design, Electronic circuit, mechanical design, clothing shoes and hats, aerospace, light industrial chemicals and many other fields. It has certain advantages and some shortcomings, advantages: simple operation, just enter the simple first letter can complete the command, with the mouse movement automatically display relevant information, you can enter the operation instructions at any time. Disadvantage: CAD is sometimes too cumbersome to operate

Cass Software is a software system based on CAD platform developed by Guangdong Southern Digital Technology Co., Ltd, which integrates terrain, cadastral, spatial data building, engineering application, earthwork calculation and other functions. Cass break the traditional model of cartography as the core, combined with the rich experience in the field of mapping and warehousing data, realize the integration of data mapping and database, and satisfy the need of topographic cadastral professional cartography and GIS building database, reduce duplication of labor. Data production, graphics processing, data building database one step. It is mainly used for land surveying and delimitation, urban parts survey, earthwork calculation function. Cass also has certain advantages and disadvantages, advantages: Easy to draw, can be plotted in accordance with the field of topographic maps, different codes represent different illustrations, shortcomings: The CAD version relied on is too low, and did not upgrade, resulting in WIN10 and CAD2006 incompatibility issues.

Matlab can easily realize the user needs of various computing functions, and has convenient data visualization function, but for the matrix has a higher requirements, difficult to grasp easily, the user requirements are higher.

Cosa is a adjustment software, in the mapping related aspects of the calculation plays an important role in the plane control network, leveling network, elevation network adjustment calculation, improve accuracy rate, and save time. However, it has very strict requirements for the input format of the data, and it takes a certain amount of time to convert.
