Cython vs. Python vs. Swift vs. TdhGIS Comparison Chart

The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. Whether you're new to programming or an experienced developer, it's easy to learn and use Python. Python can be easy to pick up whether you're a first-time programmer or you're experienced with other languages. The following pages are a useful first step to get on your way to writing programs with Python! The community hosts conferences and meetups to collaborate on code, and much more. Python's documentation will help you along the way, and the mailing lists will keep you in touch. The Python Package Index (PyPI) hosts thousands of third-party modules for Python. Both Python's standard library and the community-contributed modules allow for endless possibilities.

TdhGIS provides a robust and versatile set of tools for vector based spatial analysis. Everything needed to be performing spatial analysis within minutes is included in this easy to use software package. Feature Summary: Graphically create and edit geometric data, as with a CAD program Import Shapefiles and OpenStreetMap data Use raster images as background and a CAD drawing as an overlay Color polygons based on user data values using either discrete intervals or gradients Allocate point data to user specified buffers for points, polygons and multilines (e.g. find all gas stations within 1 mile of a highway) Allocate point data to polygons. (e.g. assign structures to hydrological basins) Allocate polygon data to other polygons. (e.g. allocate population data by census block to political boundaries) Create thiessen polygons (e.g. for all hospitals within a state, define the areas closest to each hospital)
