Gpsbabel output locations12/22/2023 ![]() The last step is to modify that URL to output the JavaScript that the Google Maps client uses internally. Fortunately, Google provides a tool to do just that! Click "Link to this page." The displayed map won't change, but the URL in the address bar will contain your query and the parameters needed to return to this map at this zoom level. To do that, we first need a URL that contains everything we need to recreate our route. Now, we need to get the output into a predictable format. After a short calculation, a map like that in Figure 4-18 appears, with the route highlighted.įigure 4-18. ![]() Enter "JFK to 350 5th Ave, New York" and hit the Search button. We'll use one of the examples given on the Google Maps home page. The first step is, of course, to get Google Maps to make some driving directions. This is possible because Google encodes the coordinates of the entire route in the JavaScript that is sent to the Google Maps client and used to generate the route that is put on the map. GPSBabel () makes it possible to convert driving directions from Google Maps into various formats usable by other software and devices. Ogr2ogr -f GPSBabel GPSBabel:mapsend:out.mapsend in.From Google straight to your Global Positioning System receiver, thanks to GPSBabel. Reading the waypoints from a Garmin USB receiver :Ĭonverting a shapefile to Magellan Mapsend format : The syntax to specify an output datasource is : GPSBabel:gpsbabel_file_format*:filenameĪlternatively, you can just pass a filename as output datasource name and specify the dataset creation option GPSBABEL_DRIVER=gpsbabel_file_format* Please refer to its documentation for more details. The support geometries, options and other creation issues are the ones of the GPX driver. (The GPX driver does not need to be configured for read support for GPSBabel write support.). The driver relies on the GPX driver to create an intermediate file that will be finally translated by GPSBabel to The USE_TEMPFILE=YES configuration option can be used to create an on-disk temporary GPX file instead of a in-memory one, What is actually supported depends on the used GPSBabel format.Īlternatively, for a few selected GPSBabel formats, just specifying the filename might be sufficient. filename can be an actual on-disk file, a file handled through the GDAL virtual file API, or a special device handled by GPSBabel such as "usb:", "/dev/ttyS0", "COM1:", etc.See the documentation on Route and Track modes for more details. This option can be used to require full data import from GPS receivers that are slow and for which GPSBabel would only fetch waypoints by default. waypoints matches the -w option of gpsbabel commmandline, tracks matches -t and routes matches -r. features= can be used to modify the type of features that GPSBabel will import.gpsbabel_format_option is any option handled by the specified GPSBabel format (refer to the documentation of each GPSBabel format).gpsbabel_file_format is one of the file formats handled by GPSBabel.The syntax to specify an input datasource is : GPSBabel:gpsbabel_file_format*::]filename The returned layers can be waypoints, routes, route_points, tracks, track_points depending The driver needs the GPX driver to be fully configured with read support (through Expat library) toīe able to parse the output of GPSBabel, as GPX is used as the intermediate pivot format. The GPSBabel executable must be accessible through the PATH. The GPSBabel driver for now that relies on the GPSBabel utility to access various GPS file formats.
