'''[http://www.OpenSeaMap.org OpenSeaMap]''' is a worldwide open source project for creation of a '''free nautical chart'''.

== History and fundamentals ==
OpenSeaMap was created in 2009 in response to a great need for freely-accessible seafaring maps. OpenSeaMap's goal is to add nautical and tourism information that would interest sailors OSM, and to present it in a pleasing way. This includes beacons, buoys and other seamarks, port information, repair shops, ship supplies and much more, but also shops, restaurants and places of interest. OpenSeaMap is part of [http://www.openstreetmap.org OpenStreetMap] and uses its database.

OpenSeaMap is an open Sea Map, and also open for future developments. The basemap is rendered using the OpenStreetMap-data. This map is extended with nautical data that is saved in the OSM-Database as well. OpenLayers is used to overlay additional nautical Information, which can be displayed in a popup by clicking on the map.

== Contact ==

: [https://lists.sourceforge.net/lists/listinfo/openseamap-develop OpenSeaMap-develop] {{English}} - Mailing-list for developers [http://sourceforge.net/mailarchive/forum.php?forum_name=openseamap-develop Archive]

== Usage ==
=== Online Charts ===
The main chart can be found [http://map.openseamap.org here]

==== Nautical Information ====
The main web page supports rendering of seamarks and nautical information. There is a wide variety of supported features.
We are working on support for depth contours.

==== Weather ====
We provide up to date global [http://map.openseamap.org/weather.php weather] forecasts through data provided by NOAA.

==== Trip Planner ====
You can measure distances at sea and plan your trip. You may even export your points to be used offline.

==== Automatic Identification System (AIS)====
We have up to date AIS data available so you can follow vessels on the online map.

=== Offline Digital Charts ===
see [[De:Navigation_program]]

=== Paper Charts ===
[https://github.com/rahra/smrender Smrender] is capable of producing paper charts as PDF. [https://www.cypherpunk.at/download/smrender/samples/ Here] is a set of various samples in different scales. There is also a set of [https://www.cypherpunk.at/download/smrender/charts/croatia/yellow_map/ charts of Croatia] in the same scale and sections as the official charts.
We do not provide a regular rendering of certain sea areas right now.
Feel free to get this job done and mail to [mailto:openseamap-devel@openseamap.org OpenSeaMap Development].

== User Contributions ==
=== Chart Features Editing ===
You can edit the chart features through [[JOSM_and_Plugin|JOSM]]. There is a SeaMark Editor Plugin available to make the editing more comfortable.
=== Contribute Water Depth Recordings ===

== Developer Contributions ==
[[OpenSeaMap-dev:Portal|Developer area]]

==Data model==
The data scheme applies to the international norm [http://www.iho.int/iho_pubs/standard/S-57Ed3.1/31Main.pdf IHO-S-57], as published by the IHO. This allows a simple exchange of data with other ECDIS-Applications. Because of the complexity of attributing seamarks, there will be (unlike the usual OSM procedure) a strict separation between database as backend and the frontend, to allow users to input data without knowing S-57. A graphical user interface will be provided in the form of three editors.
The depth data is stored in a separate database and is using PostGIS

== Languages ==
OpenSeaMap is multilingual.

The Website is available in [http://www.openseamap.org/index.php?page=start&lang=de German], [http://www.openseamap.org/index.php?page=start&lang=en English], [http://www.openseamap.org/index.php?page=start&lang=fr French], [http://www.openseamap.org/index.php?page=start&lang=it Italian], [http://www.openseamap.org/index.php?page=start&lang=es Spanish] and [http://www.openseamap.org/index.php?page=start&lang=ru Russian].

OpenSeaMap-dev:En:Depth Data

2013-05-15T14:08:16Z

Rahra: /* Crowd Sourced Data */

This Page describes the necessary efforts to retrieve and analyze depth data as well as create renderings from it

= Data Aquisition =
Depth data can be retrieved from public domain sources or from crowd sourced data.

== GEBCO ==
DIe Daten sind gerendert und stehen als Layer zur Verfügung:
{| class="wikitable"
! Zoom || Inhalt
|-
| 0..10 || Blaustufen und Schattierung
|-
| 11..18 || beschriftete Tiefenlinien, Blaustufen und Schattierung
|}

Noch zu lösende Probleme:
* der GEBCO-Layer erzeugt einen milchigen Schleier über der Basiskarte
* Tiefenlinien sind ab z=14 etwas grob (also ab da, wo dann die Flachwassertiefen beginnen) [http://dev.openseamap.org/website/map/#?zoom=14&lat=36.03097&lon=-5.49153&layers=BFTFTTTFFFF0]
* Überschneidungen von 100m-Linie und Küstenlinie [http://dev.openseamap.org/website/map/#?zoom=15&lat=36.00318&lon=-5.60819&layers=BFTFTTTFFFF0]
* Steilküsten (Cuba) [http://dev.openseamap.org/website/map/#?zoom=14&lat=19.94808&lon=-76.04289&layers=BFTFTTTFFFF0]

== Crowd Sourced Data ==
Crowd sourced data may be gathered by YOU. There are two options in development. A hardware and a software option.

=== Workflow ===
[[Datei:Workflow_depth.png]]

Here you can find the document with the previous thoughts about the workflow:
[http://osm.franken.de/wiki/FWT-Projekt%C3%BCbersicht-NMEA2Contours_2.1.ppt PPT Dokument]

=== Hardware logger ===
We are currently developing a hardware logger that may easily be plugged to the ship's network in order to log the networks data to a SD card.
That data may then be uploaded by plugging the SD card to a normal computer with internet connection for upload.
The main goal is to support NMEA 0183 data with options for NMEA 2000.

=== Software logger ===
A [[Software logger]] is in development and [http://seesea.sourceforge.net/datalogger/index.html can be downloaded here].

It currently supports:
: Bluetooth
: Serial ports
: Internet Protocol (IP)
It processes NMEA 0183 and AIS data.

For vendor specific protocols such as SeaTalk 1 you have to use a [[De:NMEA-Logger_anschliessen|converter]] to NMEA 0183 data.

NMEA 2000 support is only available if data is transcoded to NMEA 0183 by a converter.

=== Chart Plotters ===

Some chart plotters are able to save tracks out-of-the-box, e.g. several Raymarine (FSH files) and Humminbird (SON files) devices. Those files may directly be used as data source.

=== Upload Process ===
Uploading data is possible through using the [http://seesea.sourceforge.net/datalogger/index.html OpenSeaMap Data Logger Software] or via [http://depth.openseamap.org/ Web Interface].
The system is currently being tested.

[[OpenSeaMap-dev:Crowd_Sourced_Depth_Data|You'll find further information here]].

= Data Preprocessing =

== Data Condition ==
Raw data is usually erronous and must be corrected

=== Internal data problems ===
Depth data may be affected by electrical conditions and software implementations
* Data is incomplete and fail their checksum (bus errors from physical transmissions errors)
* Data is retrived out of sequence
* Data is erronous sensor data
** Approximate correctable data i.e. invalid GPS position that may be interpolated
** Uncorrectable data i.e. failed log sensor that shows slow speeds
* Data resolution is low i.e. for energy saving purposes GPS position is updated every 10 seconds instead of every second
* Sensor data is actively miscalibrated i.e. charter companies add additional draft to the sensor depth for safety reasons

=== External data problems ===
Depth data may be affected by different environmental circumstances
* The water temperature affects the ultrasound echo. An inhomogen water temperature yields unwanted echos
* The seabed affects the ultrasound echo
* The seastate affects the measurement. There even may be waves when there is no wind.
* Waves may affect the roll of the measuring vessel resulting in steep measurements that are invalid.
* The sounder sensor is not the position of the GPS antenna. A position offset including heading must be incorporated.
* The time of the measurement need not correlate with the time the position was received. This may even happen due to processing time of the hard or software.

== Data Condition Examples / Showcases ==

=== Missing measurments (Position) ===
Distribution for position updates taken from an example dataset. Left column shows the time between two consecutive measurements, right column shows how many measurements had this time update.
One can see from the distribtion that the sensor is updated every second but many measurements are one or more seconds late.
21 seconds with no position update may result in an instability of the subsequent filter.

=== Missing measurments (Position) with erronous clock ===
This example is at a 10 second position update rate. However the measurment time is faulty causing large negative and positive update rates. The clock jumps by +- one year/month/day/hour. One can further see from the many 0 time measurements that the rate at which data is sent to the nmea bus is higher than the actual position update (data is sent every second, a position update is every 10 seconds)

== Solution Proposal ==

=== Outline ===
The ship is influenced by the outlined environment which can be observed. Naturally what is observed is not the state of the
ship as i.e. the position if taken from GPS is 95% less than 10m accurate. To improve quality an estimation of the true state yields better results if this noise taken into account properly.

=== Details ===
The ship moves according to physical laws. For the easist case imagine a ship with constant velocity and direction. For any point in time you can tell where the ship is with easy math. Considering the full blown setup a ships movement is affected by many parameters such as wind speed, water current, waves, tide, and many more. The ship moves also triaxial in a dynamic way in itself (roll, pitch, yaw). Heeling even changes the measurement position with respect to the depth position. In terms of a filter this is called a system model that describes how the state of the ship may change. Given such a state you can measure what your sensor readings are and compare that to where the system thinks you are.

The [http://en.wikipedia.org/wiki/Kalman_filter Kalman Filter] is known to be the best linear estimator for such situations. Unfortunately the system model is not linear which is why the Extended Kalman Filter needs to be used in order to linearize the system at hand.

Todo:
* Construct ship system model with at least the position state and probably its course and speed or even more (depth)
* Estimate the system variance (This is a hard one, proposals welcome)
* Construct the measurement model according to the data available (GPS, Log)
* Estimate the measurement noise according to specifc sensors (DPGS is more accurate than GPS)

The estimation with the position and depth can be retrieved and stored in a database.

Pitfalls:
* If the system noise is badly chosen the estimation of the system state does not converge to the true state / measurement.
* If the system is very detailed the system variance can be reduced. The required cpu time for processing increases

Benefits:
* Having the best estimation of the true position even if measurements are noisy
* Easy and effective algorithmic processing

== Analysis ==

=== Data Sets ===
Currently two test data sets are available recorded during trips from Mallorca and the Baltic Sea.
In terms of data quality the Mallorca data shows many challenges.
* The minimum recommended sentences from NMEA showed up with false date and time readings while having correct (!!!) message checksums.
* The log on the ship was defective and delivered no readings from time to time.
* The same holds true for the water temperature.
* The GPS positions relatively imprecise because some last decimal digits are missing in the recordings.
* The GPS positions are updated every 10 seconds while other sensor readings update almost every second.
* The GPS position are sometimes way off due to false readings

The Baltic Sea data set is a little bit better
* Only a single day is available
* GPS positions are updated every second

One problem with the data is that there is time available when sensor readings were recorded. This yields problems to the filter algorithm.

=== Filter Algorithm ===
At first the Extended Kalman Filter is being analyzed. Using an apache implementation with the available data the filter quickly throw an exception that
a matrix is not invertible because of numeric instabilities. When removing this exception the filter seems to work but the removal and its effects have yet to be analyzed.
Literature suggest that a fixed interval smoother may yield better results in case of offline data processing. As it is an extension to the existing kalman filter
we may consider that for the future.

One problem are the different update rates of the sensors. As GPS may deliver positions at 0.1Hz speed is updated at 1Hz. Literature suggests that
the missing measurements shell be modelled as a random variable with the standard deviation of the sensor. It may even be possible to update covariance matrices only partially with the sensor readings received. Input for the best solution may be formulated on the developer mailing list.

== Results ==
A prototype implementation is shown in the following screenshots. An Extended Kalman Filter is being used. It has the position
and the current bearing and velocity as system state. The input is the measurement of these four observables. The system function is
good old pythagoras. In a first implementation I tried to use orthodrome distances but the system function is not differentiable which is a requirement of the Extended Kalman Filter (due to acrtan2). For small distances pythagoras should be sufficiently accurate.
The initial state is taken from the first measurement for convergence reasons.

The following gallery shows the results.
* You can see the bad position resolution and an outlier in the first screenshot.
* The second shows the same data overlaid with the applied filter. The outlier is gone and the resolution has improved.
* The third screenshot shows data from a different GPS sensor with more precision (not DGPS) versus the filtered data.

This of course is just a preliminary test and many setups need to be considered to make it work for most datasets.

<gallery>

FilteredNMEAVsOriginal.png | Unfiltered GPS data and Filtered GPS data
PreciseGPSvsFilter.png | Another precise GPS vs Filtered GPS data
</gallery>

The overall process even gives an estimation of the current error which is a capability of the [http://en.wikipedia.org/wiki/Kalman_filter Kalman Filter].
This way positional inaccuracies may be added to the overall depth measurement inaccuracy.

== Quality rating ==

Each record (time, positon, depth) should become a quality rating.

== Programm ==
Das Programm werden wir je nach anwesenden Personen, Interessen und Prioritäten gestalten und möglichst hier vorher gemeinsam planen.

; Gastvortrag
: Wir beginnen das Wochenende mit einem Vortrag:
: '''Dirk Riehle: "Open Source"'''
: Unser Gastreferent von der Uni Erlangen ist Inhaber des einzigen Lehrstuhls in Deutschland zu OpenSource. Er plant mit seinem Team mehrere Projekte zu OpenSeaMap für das Wintersemester 2010/11

; Struktur
: Die Idee ist, dass jeder "Maintainer" bzw. jedes Team eines Projektes ein Zeitfenster hat, um die zentralen Fragen mit allen anderen Entwicklern zu diskutieren und Lösungen bzw Lösungswege zu finden.
: Ergebnis soll jeweils eine ToDo-Liste sein.
: Und natürlich wie immer Zeit für's Kennenlernen und Fachsimpeln!
