geospatial software

Chapter 1, Summary:In this chapter, we briefly introduced the Python programming language and the main concepts behind geospatial development . We have seen:~that Python is a very high-level language eminently suited to the task of geospatial development.~that There is a number of the libraries which can be downloaded-make it easier to perform geospatial Python.~

The first version of each software project is beautiful. The new project starts from scratch and all content is newly developed. Because of all-new development, there is no historical burden. The first version has very few bugs. Of course, programmers also try their best to do their best. This means that in the eyes of developers, the first version can be regarded as perfect: the code is beautiful, the design is good, and the architecture is excellent
