Open-Source and Cross-Platform software for Nanometrics seismic data acquisition

The Nanometrics servers NaqsServer and DataServer can provide on-line access to seismic data and state-of-health information accepting TCP/IP connections and forwarding the requested data to each client program. NaqsServer collates and stores in near-real-time incoming data in ringbuffers whereas DataServer provides data of the past stored in NaqsServer ringbuffers. In order to implement the Nanometrics subscription protocols, the author developed a software consisting of a library called libnmxp and a tool called nmxptool. The library exposes a set of documented APIs which allow to communicate with the Nanometrics servers. The tool, based on libnmxp, allows to retrieve or monitor real-time data and data of the past.

nmxptool can be used in three different ways: (see also the diagram)

• stand-alone to monitor data or save retrieved data in mini-seed records
• launched as an Earthworm module to redirect data into the EW-rings
• like a Seed-Link plug-in to feed the SL-server

The main contribute, as regards other similar software, is the capability to manage Raw Stream connections by buffering and sorting all received packets, included the retransmitted ones, guaranteeing a good compromise between data continuity and low latency. Besides, nmxptool allows to retrieve Data-On-Demand with minimum delay after request. Software is open-source and released under GNU Library General Public License. It has been written in C language using the GNU Build Tools (automake, autoconf and configure script) and taking in account the cross-platform compilation aspects, in fact, it can run on almost all the Unix-like operating systems, Mac OS X, Windows and either 32-bit or 64-bit architectures.
