In April 2010 I published a ticket to locate the main actors of the electronic charting. Passing time, to refresh this information, because of the last movements of companies.
The purchase of C-Map by Altor investment fund to Jeppesen (Boeing group) the last month has been mentioned recently in this blog. It allows to bring back in Europe one of the leaders of the private charting that will be closely associated with the Group Navico, and its three brands of marine electronics Simrad, B&G and Lowrance.
This brand designs maritime and terrestrial navigation software for PC and Mac , provides a charting service via the server X-Traverse, and sell some mobile equipment and accessories dedicated to navigation. We learn that Fugawi just be purchased to the Canadian Northport Systems Inc.. by the American family company Johnson Outdoors located in Racine, Wisconsin. It will probably allow to associate this new acquisition with the navigation devices Humminbird already held by this company. (continue…)
For this 300th blog Navigation Mac entry (Eh, yes, time flies !), I invite you to a survey to find out what charting application is the most used according to the type of practiced navigation. From daily trip to ocean crossing, the need is not the same and this should necessarily guide the choice of the navigation application. But it has yet to prove. Of course we speak here only Apple iOS on iPhone and iPad applications.
After two weeks and 260 answers, here are the results.
A cache is, in computing, a memory that stores a copy of the data from a source, in order to reduce access by computer hardware or application in reading time . About Weather4D 2.0 the data source is the internet (Geogarage servers) and the cache storage uses the non-volatile flash memory of iPad.
The scanned raster charting is broken down into portions of 256 x 256 pixels called "tiles" ". Each scale level has its own tiles coming to replace the tiles of lower level while zoom-in or higher when zoom out. The computing power of recent mobile GPUs, associated with tiles storage in memory cache, allows the use of "tiled" display process making seamless scale switching. This implements the tens, or even hundreds of tiles depending on the details density of a selected maritime area. Compression algorithms come furthermore increase display speed, as well as the geographic coverage for a given cache memory size.
But why cache tiles ? (continue…)
Expected for almost two years, hoped more, we despaired… but here it is in my hands. Alleluia ! The Wi-Fi NMEA0183 multiplexer, Gateway NMEA2000 and translator SeaTalk is available in France (¹).
The same size and as light as his little brother, Miniplex-2Wi (²), its plug terminal is significantly neater : no need for screwdriver, the connectors are equipped with spring clamps. The signage is also much more readable in color, and 4 lights leds allow a look to check the operation : strings scrolling NMEA2000 and/or NMEA0183, connection to a Wi-Fi device, and overflow if applicable.
But the apparent simplicity is misleading and the thing hides a real potential.
Yachtmen my friends, do you know Altor ? Of course not, don't look for, me either until this morning. Altor is an investor in Northern Europe that presents itself as :

But why I'm talking about ? (continue…)
In two previous posts I explained Navionics new trade policy as well as changes for the purchase of charts into the website x-traverse.com (¹).
Misunderstandings have led me to request clarification on the modalities of activation of charts region, and despite some repetitions already outlined above, Here is a summarized development of the terms and conditions currently offered by X-Traverse. (continue…)
SailRacer UAB is a small Lithuanian company founded in 2013 by a team of experienced developers and regatta passionate . They design solutions for the sailors and clubs, both software and devices, focusing on developing applications and essential accessories to the processing of navigation data for mobile devices and their operation through the Cloud. They provide an application specifically dedicated to the regatta, Sail Racer, and the first Bluetooth NMEA gateway in the market, DataLinker.
DataLinker, a Bluetooth NMEA gateway
The DataLinker allows to receive data from the instruments on a smartphone, a tablet or other compatible mobile device, thanks to the Bluetooth Smart technology (¹). You can use wind data, Compass, log, sounder and GPS with any dedicated application connected to the internet in Wi - Fi and so share this data via the Cloud.
