6.11 Export Routes

A limited selection of exports are available for some GPSs and Google Earth (GE). Currently only Garmin ADM, GPX,

Furuno NN3, Furuno GP1870, and KML formats are supported. These handle GPS file transfer support and Google

Earth. The GE export makes a line showing the route(s) derived from a routes file. If you want the route points

identified with names and icons in GE, then export the routes file also as a KML waypoint file and open both KML files

in GE.

You can make a routes file by using the Trip Planner. This allows you to pick points out of a waypoints file that will

constitute the routes. Put “STRT” in the rating field for the first point in each route (can be done after making the trip

plan). That tells the software that this is the beginning of a route. Put the name you want for the route into the group

field of the route points and the route description also in the description field of the first point. The file can have up to

200 routes with as many as 1000 points in a route. Just be sure that your GPS can handle the number of routes, the

number of points in each route, and the total number of route points. While the routes file in SeaMarks may have many

fields, only Lat/Lon, Name, and Description might be imported by the GPS. In some cases the Route takes the

name and description of the first point.

A special note for Furuno GP1870 routes. This model Furuno imports waypoints and routes in the same file (one with a

PNT extension). Whenever you import a file to the GPS, all the existing points in the GPS are erased. Therefore, to do

this successfully, you need to format a file with this in mind. One way to do this is to create a waypoint file and a trip or

route file and then combine them (with the waypoints first). If you do not want to change the waypoints already in the

GPS, then save them to the card, import them into SeaMarks, and then combine the routes file with this file before

exporting the file as a routes file back to the card. There can be no more than 50 routes in this file. The points in the

routes can have the same names as the waypoints as this GPS keeps track of them by index numbers that will be assigned

while exporting. Each Route takes the group and description of the first point in it (which has “STRT” in the rating

column).
