Native function st_distance will ignore SRID for now and return a value which represents a distance on a planar – not very useful for our purposes (may be useful for order by / compare).

That means that if I want to calculate the distance of my favorite bike path in miles or kilometers, I’ll still have to use a stored function (see below for an example) or write an application code for that. The bad news is that except for the st_distance_sphere, all other functions use planar geometry (no change since MySQL 5.6) and do not support Spatial Reference System Identifier ( SRID).
Manyi Lu from MySQL server team provides more reasoning behind the choice of Boost.Geometry. This is great news, as originally GIS was implemented independently from scratch with a very limited set of features.
New functions: GeoHash and GeoJSON. With GeoJSON we can generate the results that are ready for visualizing on Google Maps.This is not surprising, as stored procedures are slow computationally – especially for trigonometrical functions. The native function is ~20x faster than the stored procedure (in an artificial benchmark, see below). st_distance_sphere: native function to calculate a distance between two points on earth. Finally it is here as well! Like many others, I’ve created my stored procedure to calculate the distance between points on earth using haversine formula.Finally it is here! This was a long overdue feature, which also prevented many companies from converting all tables to InnoDB. MySQL 5.7 introduces the following major improvements and features for GIS: In this blog post, I’ll look into what is new in MySQL 5.7 and how we can use those new features in practice for geo-enabled applications.

In my previous blog entries I’ve shown how to create geo-enabled applications with MySQL 5.6 and use MySQL 5.6 geo-spatial functions. I’ve used GIS features in MySQL for a long time.

The user interface in Tauri apps currently leverages tao as a window handling library on macOS and Windows, and gtk on Linux via the Tauri-team incubated and maintained WRY, which creates a unified interface to the system webview (and other goodies like Menu and Taskbar), leveraging WebKit on macOS, WebView2 on Windows and WebKitGTK on Linux.MySQL 5.7 has been released, and there are some exciting new features now available that I’m going to discuss in this blog - specifically around geographic information system (GIS). The backend of the application is a rust-sourced binary with an API that the front-end can interact with. Developers can integrate any front-end framework that compiles to HTML, JS and CSS for building their user interface. Tauri is a framework for building tiny, blazing fast binaries for all major desktop platforms. Tauri - Build smaller, faster, and more secure desktop applications with a web frontend.
