A web based Metadata Catalog Server for data description and discovery. Supports both generic and geospatial data discovery. It implements international standards (e.g. ISO19115/19139/19119, ISO19115-3, DCAT-AP, CSW 2.0, OGC API Records). It originates from the United Nations and is used by many governments as geoportal software. Active development and discussion takes place on GitHub and OSGeo Discourse.

eviltransform is a compact library for converting geographic coordinates between the global WGS-84 system (used by GPS) and the Chinese GCJ-02 system (used by many Chinese map services such as Google Maps China and AutoNavi). The project implements forward and inverse transformations (WGS→GCJ and GCJ→WGS) as well as a higher-precision inverse method (GCJ→WGS exact) that trades speed for sub-meter accuracy, and it includes a utility for computing geodesic distance in meters. It’s implemented...

Warning: I found an error if the DR position is on the southern hemisphere. The PUB249 pdf files did not show this error and are correct (as far as I checked). All Revisions 8+ and the Windows release have been fixed. This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18).

An integrated set of functions that automate many navigational and tidal calculations which can be time consuming and error prone if performed manually. It can be linked to a GPS to automatically receive position fixes and other information.
