Application for navigation ?

I'm not a follower of the comparative tables for applications, and I already said, so it is difficult to measure and compare completely subjective aspects such as ergonomics, the graphic quality of a user interface, the speed of execution of such and such function. However, a recent comment in a previous article I was sufficiently annoyed that this makes me an attempt of comparison of purely objective aspects, namely the offered functions and prices.

What iPad for navigation ? [Update]

You are more likely to wonder about the choice of an iPad to use navigation. Unfortunately did not have time to respond to every request (retirement is still beyond my horizon), a ticket is required. Four years after a similar article (¹), of course now completely obsolete, It was time to redo this issue. (continue…)

Roseanor, 2000 miles at cross-purposes around Europe

Transporting a boat from Corsica to Normandy in may, It's a bit like making around the world backwards from East to West, in more modest. Two - thousand nautical miles on the water against winds and tides, four and a half weeks of sea, with thirteen days of stops forced waiting for favourable conditions, three - hundred and fifty hours of engine to support the sails, 1000 litres of diesel fuel, multiple Corsican wines cubis, Spanish and Portuguese to calm nerves, a few packs of water to calm the thirst, and hundreds of hours to test the new features in development of… Weather4D 2.0 !

Navionics Boating 9.0 the point about what's new

Updated on 17 May, Navionics Boating presents some modifications, in the presentation and functionality.

First of all only subsist Navionics "Boating" for iPhone and "Boating HD" » for iPad. The old names have disappeared, happily because confusion was great. Version purchased with built-in charting has the name of the region, for example "Europe HD" for iPad. On the other hand, there is a free version called "Seas and Lakes" which allows to test then buy a chart of the area of choice, and additional options. (continue…)

Weekends onboard training « Navigate with an iPad» 2016

Training ACM

The ACM basis in the Gapeau River

For the fourth consecutive year the partnership is renewed with ACM-Catamaran, sailing school affiliated with the French Sailing Federation.

In 2016 training weekends are programmed at the outset of Hyères (Base Le Gapeau) and at the start of La Rochelle (Port des Minimes).

Actors of the electronic charting [6 years later]

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.

c-map-logoC-Map

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.

Fugawi_LogoFugawi

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…)

Survey : which application for which navigation ? [Results]

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.

2016 Year of GALILEO

Since my first post on GALILEO end 2011 (¹), Europe's space has increased. Despite the economic uncertainties and many budgetary restrictions, Course and schedule have been maintained thanks to a community political flawless. This is to be welcomed because many other areas of European action didn't have the scoop.

The year 2016 has already been dubbed "the year of GALILEO".. This was the clear message of the Munich Satellite Navigation Summit (²) early March. The Munich Summit covered all GNSS systems, but this year focus was squarely on GALILEO. (continue…)

Cache me these tiles !

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. tilesThis 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…)

Weather4D 2.0.11 a bunch of new features and improvements
