C ++ open source GIS middleware Class Library: Gdal (raster)/OGR (vector) provides various types of read/write support Geos (geometry engine open source) is a class library for space topology analysis based on C ++ and is released following the lgpl protocol. The geos Class Library provides a wide range of spatial topology operation functions to determine the relationships between geometric objects and form new geometric objects after spatial analysi

According to the actual work needs, the author uses SVG and related technology in Web browser to realize the Web GIS Management System (hereinafter referred to as Webgis), and obtains the very good result.

It has unparalleled advantages in analyzing geographical information. Some macro geographic information, one-dimensional geographic information, such as rivers and highways, and two-dimensional geographic information, such as vegetation, lakes, and population quantity, in terms of analyzing and processing the geographical informat

The http://blog.3snews.net/space.php?uid=16796do=blogid=22870 of Jiang waves1984 Turing Award winner, the inventor of the Pascal language, Professor Niklaus Wirth, has given the program a classic definition of "program = algorithm + data structure", sharply. In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a problem, and the latter provides the object of solving the problem.The term "algorithm" d

The GIS student programming is inferior to the computer, does the mapping is inferior to the study surveying and mapping, does not have the geography to study the geography, I now began to learn the programming how to learn also to be unable to learn the computer how to do?This is a simple question, so if you go to bed now and catch them, you can go to sleep.1, the family asked you to learn what professional, not to mention geographic information syst
