Python vs. Ruby vs. Swift vs. TdhGIS Comparison Chart

Wondering why Ruby is so popular? Its fans call it a beautiful, artful language. And yet, they say it’s handy and practical. Since its public release in 1995, Ruby has drawn devoted coders worldwide. In 2006, Ruby achieved mass acceptance. With active user groups formed in the world’s major cities and Ruby-related conferences filled to capacity. Ruby-Talk, the primary mailing list for discussion of the Ruby language, climbed to an average of 200 messages per day in 2006. It has dropped in recent years as the size of the community pushed discussion from one central list into many smaller groups. Ruby is ranked among the top 10 on most of the indices that measure the growth and popularity of programming languages worldwide (such as the TIOBE index). Much of the growth is attributed to the popularity of software written in Ruby, particularly the Ruby on Rails web framework.

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)
