GPVExternalMap

The GPV can launch external web mapping applications zoomed and centered on the same location as the current GPV map. This table defines the available external maps.

Columns

• DisplayName - The name of this external map as shown on the GPV (not null).
• URL - The URL for launching the external map website (not null). See URL Substitutions below for details on formating the URL.
• SequenceNo - A number specifying the display order of this external map on the pulldown list (not null).
• Active - Specifies whether this external map link is available for use, 1 for yes and 0 for no. If null, defaults to 0 (no).

URL Substitutions

The GPV will substitute particular character strings in the URL with data appropriate to the current map extent. For example this configured URL for Google Maps:

http://maps.google.com?ll={lat},{lon}&z={lev}

will be converted to a URL with substitutions like this for launching:

http://maps.google.com?ll=42.5346,-71.9334&z=16

The following substitution strings are supported:

• {lev} - zoom level (Google-compatible)
• {lat} - map center latitude
• {lon} - map center longitude
• {minlat} - map extent minimum latitude in decimal degrees
• {minlon} - map extent minimum longitude in decimal degrees
• {maxlat} - map extent maximum latitude in decimal degrees
• {maxlon} - map extent maximum longitude in decimal degrees
• {x} - map center X in the measurement projection's units
• {y} - map center Y in the measurement projection's units
• {minx} - map extent minimum X in the measurement projection's units
• {miny} - map extent minimum Y in the measurement projection's units
• {maxx} - map extent maximum X in the measurement projection's units
• {maxy} - map extent maximum Y in the measurement projection's units
• {xm} - map center X in the measurement projection converted to meters
• {ym} - map center Y in the measurement projection converted to meters
• {minxm} - map extent minimum X in the measurement projection converted to meters
• {minym} - map extent minimum Y in the measurement projection converted to meters
• {maxxm} - map extent maximum X in the measurement projection converted to meters
• {maxym} - map extent maximum Y in the measurement projection converted to meters
• {xft} - map center X in the measurement projection converted to feet
• {yft} - map center Y in the measurement projection converted to feet
• {minxft} - map extent minimum X in the measurement projection converted to feet
• {minyft} - map extent minimum Y in the measurement projection converted to feet
• {maxxft} - map extent maximum X in the measurement projection converted to feet
• {maxyft} - map extent maximum Y in the measurement projection converted to feet

See GPVSetting for details on the MeasureProjection setting.
