FAQ

Frequently Asked Questions

Everything you need to know about Marine Barograph

What is the Marine Barograph app?

The Marine Barograph app is an enhanced barograph for marine and land travel. It automatically stores atmospheric pressure, GPS data, course, and speed, providing detailed pressure trend analysis and export capabilities.

Does the Marine Barograph app record pressure data automatically?

Yes, the Marine Barograph app automatically stores atmospheric pressure data. It records pressure, time, date, GPS position, course over ground, and speed over ground, even when running in the background.

How long can the Marine Barograph app graph pressure data?

The Marine Barograph app can graph pressure data over various time intervals. These range from 30 minutes up to 16 days, allowing for comprehensive trend analysis.

Can I view the collected data in the Marine Barograph app?

Yes, you can view the stored data directly within the Marine Barograph app. It provides a log of voyage or land travel, including navigation information and pressure data.

How can I export data from the Marine Barograph app?

The Marine Barograph app allows you to export stored pressure data and GPS tracks. Pressure data can be exported by time range, and GPS positions can be exported as a GPX file.

Does Marine Barograph display pressure trend arrows?

Yes, the Marine Barograph app displays prominent pressure trend arrows. These arrows indicate the pressure trend based on changes over the past one hour, aiding weather analysis.

Can the Marine Barograph app share data wirelessly?

Yes, the Marine Barograph app shares both pressure and position information wirelessly. It broadcasts data via WIFI in UDP mode on a user-selected port, acting as a source for other navigation systems.

What options are available for pressure display in Marine Barograph?

The Marine Barograph app offers options for pressure display. Users can choose between sea level or station pressure, and adjust the precision and latitude and longitude formats in the settings.

Can I use an old iPhone as a dedicated barograph with Marine Barograph?

Yes, the Marine Barograph app can convert an older iPhone (iPhone 6 or newer) into a valuable stand-alone electronic barograph and voyage data logger. It provides continuous viewing when plugged in.

Does the Marine Barograph app include a help file?

Yes, the Marine Barograph app includes a full Help file. It details operation and provides tips on using atmospheric pressure for navigation, and is also viewable online.

Description

This app includes the same functionality as our free Marine Barometer app available in the App Store, with several significant enhancements added. You can review the basic features of the design by installing and becoming familiar with the free Marine Barometer app. New features in this Marine Barograph app include: automatic storage of atmospheric pressure during all times the app is running, even when in the background, with time and date, GPS position, course over ground (COG) and speed over ground (SOG). The pressure data can be graphed (pressure versus time) over several time intervals from 30 min on up to 16 days. The graphs can be pinch zoomed and panned for more detail and double tapped to reset the scales. Slide your finger across the graph to read time and pressure at specific points. Large digital displays can be viewed from a distance, including prominent pressure trend arrows (visible when data one hour old is available). On the three-hour display, the official pressure tendency is computed and displayed, and the shape of the curve in view can be used to determine the pressure tendency characteristic code used in official ship reports. Also new are options for pressure display (sea level or station), precision, and latitude and longitude formats. The stored data can be viewed from within the app or exported and shared according to time range of the storage files. The stored data are effectively a log of the voyage (or land travel) with navigation information as well as pressure data. Besides the pressure data, your track of GPS positions can also be exported as a GPX file to view in a navigation program or Google Earth. The app will also share wirelessly both pressure and position information with nearby devices. The data are broadcasted from the app via WIFI in UDP mode on a user selected port, so that the app can serve as a position source or pressure source for other navigation programs or devices, which makes it an excellent back-up to standard electronic charting systems. Or use it as a high-performance, stand-alone barograph. This app can convert a second or older iPhone (iPhone 6 or newer) not otherwise in use into a valuable stand-alone electronic barograph and voyage data logger. Just load the app and plug it in for continual viewing. A full Help file with details of operation and tips on the use of atmospheric pressure in navigation is included in the app. This file can be viewed online at https://www.starpath.com/marinebarograph along with videos showing how to use the app.
