Open Source Libraries

The development community in building GIS solutions is sustaining an enormous level of effort. The GeoAPI project aims to reduce duplication and increase interoperability by providing neutral, interface-only APIs derived from OGC/ISO Standards.

Java Marine API is an NMEA 0183 library for Java. For furher info and latest source code, see project's Github pages. http://github.com/ktuukkan/marine-api/

LGML is a GML parser under the LGPL license. The aim is to parse a GML document or fragment in order to get a WKT output. 2D and 3D inputs are both handled, but it is not permitted to have mixed geometries. The caller can choose if the input coordinates are parsed as X, Y, Z (if present) order, or Y, X, Z (if present) order. The willing of the project is to be a starting point useful for developers that need to parse GML objects in order to use them, for example, in the context of OGC catalogue projects. The library is compiled using Java 1.5 or 1.6. For now, supported inputs are: LineString, MultiLineString, MultiPoint, MultiPolygon, Point, Polygon, MultiSurface (in an experimental way: the only child object handled is Polygon). At the following URL: http://95.110.227.201:8080/lgml is exposed a minimal web interface in order to test it.

The aim of this project is to create a full utility suite for NMEA protocols (best known from GPS devices). First goal is a full implemenation of the NMEA 0183 protocol 3.0 (without proprietary extensions). The library provides parsers for NMEA sentences, gpsd-like network daemons and data generators for simulation and testing. This allows advanced sensor handling from cellphones/tablets/laptops with GPS up to vehicles/ships with NMEA sensors on board.
