All nautical charts can be downloaded easily and comfortably with the download-layer in the online-fullscreen-chart: choose menu "Tools > download chart". Map overview in zoom=5. Choose a chart, define chart-format and off you go! Charts are in zoom=10, zoom=14 and zoom=16. Our charts are prepared to be used with a lot of navigational software (devices). The charts work with "SeaClear", "OpenCPN", "Fugawi", "Touratech" and many other programs.
The following chart-formats are available:
KAP | non Maptech BSB/KAP |
WCI | SeaClear |
PNG | picture-file (frameless) |
JPR | Fugawi calibration-file |
CAL | TTQV calibration-file |
KMZ | Keyhole Markup Language (KML zipped) import for Garmin or Google |
To use the charts with Fugawi-software you have to load the xxx.png-picture-file as well as the corresponding calibration-file xxx.jpr. Touratech applies the same procedure. The calibration-file for Touratech is xxx.cal, the png-picture-file is the same as for Fugawi. We have tested the functions, but there could be unrevealed failings. We would be glad about an echo in our map-mailing-list.
In the Netherlands a lot of waterways lying close together cause many intersections and are therefore hard to follow up. For that reason the whole area of the Netherlands is displayed at zoomlevel 16. The files are enumerated by column and line from Ned_0101 to Ned_1821. Areas of the German Ocean without sea-marks are not displayed. To make the Netherlands-charts usable on Garmin-devices, we make the chart-size to 40 tiles width and 36 tiles height.
Garmin
Garmin's nautical chart plotters and some handheld devices can use OpenSeaMap vector based chart. You can save the whole chart of Europe to memory and it takes up only 3.5GB of SD card space. Garmin nautical chart plotters as well as Colorado, Oregon and Dakota can show the nautical chart in this form.
Equipped with the latest firmware-release, Garmin's navigation- devices Colorado, Oregon and Dakota are even able to show scanning-pattern-charts. In the online-fullscreen-chart: choose menu "Tools > download chart". The file-format of these charts has to be KMZ. By the scanning-pattern-format all OpenSeaMap-sea-marks are displayed the same way as in the online-view. There has to be only one single KMZ-file in the directory CustomMaps on the Garmin device. Nevertheless you can use several KMZ-files, if you save them in other directories and move one for the time being, if needed, to \Garmin\CustomMaps\.
Android
The chart works with several navigation programmes. We are looking for a programmer to work on the app featuring a vector chart.
