The parameter "label_color" specifies the color of the label.

For example Dakar:

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=14.7205&lon=-17.4538&label=Dakar&label_color=green&lang=en

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=14.7205&lon=-17.4538&label=Dakar&label_color=white&lang=en

Parameter "scale"

Standard value: "scale" = fixed

Accepted values: fixed, variable

"scale" specifies how the shown parameter is scaled:

  • fixed = the scale is fixed (e.g. wind speed 1-12 BFT). A disadvantage is the inaccurancy if there are only small values in the forecast area, an advantage is the comparability as same colors mean same values at different forecast maps.
  • variable = the scale is variable. The maximum is always the highest value in the forecast map. An advantage is the accurancy if there are only small values in the forecast area, a disadvantage are the different colors for the same values in different forecast maps.

For example Manaus in the Amazonas and Cape Horn, island Homos:

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=-3.1328&lon=-60.0046&nx=770&ny=595&label=Manaus&lang=en&scale=fixed

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=-55.9797&lon=-67.2762&nx=770&ny=595&label=Cape Horn&lang=en&scale=fixed

You see immediately with "scale=fixed" in the comparasion, that the wind speed in the rain forest is slower then at Cape Horn, but it´s difficult to recognize the differences in the wind speed arounf Manaus.

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=-3.1328&lon=-60.0046&nx=770&ny=595&label=Manaus&lang=en&scale=variable

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=-55.9797&lon=-67.2762&nx=770&ny=595&label=Cape Horn&lang=en&scale=variable

It´s easy to recognize the different wind speed within the particular forecast maps with "scale=variable", but it´s difficult to compare the values of the differend forecast maps.

Parameter "projection"

Standard value: "projection" = latlon

Accepted values: latlon, scaled, nps, sps, orthogr, mollweide, robinson

The parameter specifies which map projection will be used to display the weather map:

  • latlon = The equirectangular projection (also called the equidistant cylindrical projection, geographic projection, or la carte parallélogrammatique projection, and which includes the special case of the plate carrée projection or geographic projection) is a simple map projection.
  • scaled = In principle like the "latlon" projection, except the aspect ration is not maintained, it´s variable. The map is stretched to use the whole drawing area.
  • nps = The azimuthal equidistant projection with view on the north pole is an azimuthal map projection. It has the useful properties that all points on the map are at proportionately correct distances from the center point, and that all points on the map are at the correct azimuth (direction) from the center point. A useful application for this type of projection is a polar projection which shows all meridians (lines of longitude) as straight, with distances from the pole represented correctly.
  • sps = The azimuthal equidistant projection with view on the south pole is an azimuthal map projection. It has the useful properties that all points on the map are at proportionately correct distances from the center point, and that all points on the map are at the correct azimuth (direction) from the center point. A useful application for this type of projection is a polar projection which shows all meridians (lines of longitude) as straight, with distances from the pole represented correctly.
  • orthogr = The use oforthographic projection in cartography dates back to antiquity. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective (or azimuthal) projection, in which the sphere is projected onto a tangent plane or secant plane.
  • mollweide = The Mollweide projection is an equal-area, pseudocylindrical map projection generally used for global maps of the world or night sky.
  • robinson = The Robinson projection is a map projection of a world map which shows the entire world at once. It was specifically created in an attempt to find a good compromise to the problem of readily showing the whole globe as a flat image.

Now some examples to illustrate the different kinds of projections:

First the standard projection "latlon", the equirectangular projection. With this projection it´s possible to generate any details of the earth (see other examples above):

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=0&lon=0&latrange=180&lonrange=360&projection=latlon&nx=900&ny=700&lang=en

An example of "scaled". Also with this projection it´s possible to generate any details of the earth (see other examples above):

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=0&lon=0&latrange=180&lonrange=360&projection=scaled&nx=1000&ny=300&lang=en

An example of "nps", a view on the north pole:

"lat" has to be between 45 and 90. "latrange" must be (90-lat)*2. With "lon" the map can be rotated around the center. "lon" has to be between -180 and 180. "lonrange" must be 360. Only considering this rules will produce resonable maps.

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=45&lon=0&latrange=90&lonrange=360&projection=nps&nx=800&ny=720&lang=en

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=75&lon=-90&latrange=30&lonrange=360&projection=nps&nx=800&ny=720&lang=en

With "sps" it´s possible to look on the south pole:

"lat" has to be between -45 and -90. "latrange" must be (90-|lat|)*2. With "lon" the map can be rotated around the center. "lon" has to be between -180 and 180. "lonrange" must be 360. Only considering this rules will produce resonable maps.

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=-45&lon=0&latrange=90&lonrange=360&projection=sps&nx=800&ny=720&lang=en

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=-75&lon=90&latrange=30&lonrange=360&projection=sps&nx=800&ny=720&lang=en

With "orthogr" it´s possible to look on the equator:

"lat" must be 0. "latrange" must be 180. With "lon" the map can be rotated around the poles. "lon" has to be between -180 and 180. "lonrange" must be 180. Only considering this rules will produce resonable maps.

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=0&lon=25&latrange=180&lonrange=180&projection=orthogr&nx=800&ny=720&lang=en

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=0&lon=-90&latrange=180&lonrange=180&projection=orthogr&nx=800&ny=720&lang=en

With "mollweide" would map in mollweide projection will be generated:

"lat" must be 0. "latrange" must be 180. With "lon" the map can be rotated around the poles. "lon" has to be between -180 and 180. "lonrange" must be 180. Only considering this rules will produce resonable maps.

If "lon" is not equal 0, at the left and right side to much of the country contours will be drawn. The area of the weather data is absolutly correct.

https://weather.openportguide.de/cgi-bin/weather.pl/weather.png?var=wind_stream&lat=0&lon=0&latrange=180&lonrange=360&projection=mollweide&nx=1000&ny=700&lang=en

With "robinson" a world map in robinson projection will be generated:

"lat" must be 0. "latrange" must be 180. With "lon" the map can be rotated around the poles. "lon" has to be between -180 and 180. "lonrange" must be 180. Only considering this rules will produce resonable maps.

If "lon" is not equal 0, at the left and right side to much of the country contours will be drawn. The area of the weather data is absolutly correct.

https://weather.openportguide.de/cgi-bin/weather.pl?var=swell_height_direction&lat=0&lon=-160&lang=en&lonrange=180&latrange=120&nx=770&ny=595&unit=ft

swell_period:

Visualization of the swell period.

The color of the shading indicates the period time of the swell.

Example:

https://weather.openportguide.de/cgi-bin/weather.pl?var=swell_period&lat=0&lon=-160&lang=en&lonrange=180&latrange=120&nx=770&ny=595&display_type=shaded

sea_surface_current:

Visualization of the Sea surface current.

The color of the shading indicates the speed of the current.

Limitation: The calculated grafic must not contain the 180° line, otherwise one side of the line is not calculated.

Example:

https://weather.openportguide.de/cgi-bin/weather.pl?var=sea_surface_current&lat=0&lon=-130&lang=de&lonrange=90&latrange=60&nx=770&ny=595

sea_surface_temperature:

Visualization of the Sea surface temperature.

The color of the stream lines indicates the sea surface temperature.

Limitation: The calculated grafic must not contain the 180° line, otherwise one side of the line is not calculated.

Example:

https://weather.openportguide.de/cgi-bin/weather.pl?var=sea_surface_temperature&lat=0&lon=-130&lang=de&lonrange=90&latrange=60&nx=770&ny=595&display_type=shaded

sea_ice_coverage:

Visualization of the Sea ice coverage.

The color of the shading indicates the sea surface caverage.

Limitation: The calculated grafic must not contain the 180° line, otherwise one side of the line is not calculated. The ice covered area is calculated only by the influence of the energy balance of the ocean (Wind and currents are ignored.) and can be partly significantly different compared with the reality.

Example:

https://weather.openportguide.de/cgi-bin/weather.pl?var=sea_ice_coverage&lang=de&lat=75&lon=0&latrange=30&lonrange=360&projection=nps&nx=770&ny=595&display_type=shaded

sea_ice_thickness:

Visualization of the Sea ice thickness.

The color of the shading indicates sea ice thickness.

Limitation: The calculated grafic must not contain the 180° line, otherwise one side of the line is not calculated. The ice thickness of the ice is calculated only by the influence of the energy balance of the ocean (Wind and currents are ignored.) and can be partly significantly different compared with the reality.

Example:

https://weather.openportguide.de/cgi-bin/weather.pl?var=sea_ice_thickness&lang=de&lat=75&lon=0&latrange=30&lonrange=360&projection=nps&nx=770&ny=595&display_type=shaded
