The Haversine formula => Calculate distance between to WGS84 Points

January 22, 2016 Cantu Leave a comment

Hi,
I think might be helpful, today for a customer i do the Haversine formulas for Firebird Sql as a stored procedure.

This formula allow you to calculate the distance in meter between two WGS84 datum points(degree points of Earth).

You can call the procedure like this:

SELECT * FROM HAVERSINE_GENERIC(1, 45,474081, 9,179348, 45,456091, 9)

Are you fluent in English and SQL?

November 11, 2015 Cantu One comment

The Firebird Docs team is calling for people who are fluent in both English and Firebird’s SQL to assist with reviewing the English text of the Firebird 2.5 Language Reference manual. Of 10 chapters and 8 Appendices, 4.5 chapters are still untouched by reviewers. It would be good to have the reviewing done to coordinate with the forthcoming 2.5.5 release but correctness takes priority.

Still to do are: half of the DDL chapter, DML, PSQL, Functions and Variables, Transactions.

If you feel able to help with the review, please subscribe to the [firebird-docs] list here and make yourself and your preferred topics known.
