I have been using oruxmaps for long distance mountain hiking for several years now.

I always activate the route option "Colored path with slope" which helps a lot by letting you know at a glance the slope that is coming next, or the overall profile of the active route, just by looking at the colors of the route.

However, I find the range of slopes in the existing "Slope colors legend" (which ranges from -25% to +25%) as being very narrow for hiking use. In the mountains it is not uncommon to hike slopes up to +/-40% and even 50%, no need to be a climber to have to hike those!!!

I believe the legend that we have in Oruxmaps has probably been inspired in car or bike use. I guess we are many using Oruxmaps for hiking though.

In practical terms, while hiking you read the existing legend as follows:
1) All greens, yellows, oranges, light to medium blues: comfortable almost flat terrain.
2) Red: uphill, anything between an intermediate to an extremely demanding uphill slope.
3) Blue: downhill, anything between regular descent to a very steep dangerous descent.

As you see, a legend with 7 colors has only 3 practical meanings when applied to hiking.

I would propose two alternatives if we want to improve this legend:

1) To have more than one choice for "Slope colors legend", the extra hiking legend showing the same existing color range but applied to a wider range of slopes going from -40 to +40%.

2) If having to choose legends is technically complicated, we could just add extra colors at both ends of the scale: for the extreme uphill slopes, above 25%, black color; for extreme downhill slopes, under -25%, purple color.

Utilizo oruxmaps para travesia de montaña de larga duración, llevo usándolo unos cuantos años en travesías de cientos de kilómetros sobre todo en los Pirineos.



Encuentro extremadamente útil el "Trazo coloreado pendiente" que muestra en una ruta la pendiente mediante un código de colores.



La opción "leyenda colores pendiente" muestra una única posible gradación de colores para pendientes entre -25% y +25%, aunque en la practica no es una gradación sino 7 colores discretos diferentes: uno verde para horizontal, dos naranjas y un rojo para subidas y tres tonos de azul para bajadas. Me parece un número de colores suficiente, que se asocian de forma natural a pendientes horizontal, suave, media y fuerte (subiendo y bajando), los siete colores mencionados en total.



No obstante, en la práctica de travesía de montaña, tras años usando esta función, los topes de escala de pendiente en un valor de 25% me resultan ridiculamente bajos para montaña a pie. En la práctica uno termina leyendo los tres colores claros (verde, azul claro y naranja claro) como que "ni sube ni baja"; el naranja oscuro es subida suave y el rojo engloba todo lo demás desde una pendiente media hasta una fuerte o muy fuerte y extenuante.



En mi opinión una escala de colores hasta 25% puede ser muy adecuada para bicicleta, pero totalmente inapropiada para travesia de montaña donde 20-25% es una pendiente MEDIA y no es infrecuente encontrar pendientes fuertes de 30-35% e incluso muy fuertes de 40-50% e incluso picos superiores al 50%.



Propongo que pueda  elegirse otra "leyenda colores pendiente", manteniendo la actual Y CREANDO OTRA NUEVA PARA HIKING CON LOS MISMOS COLORES PERO CON COLOR NARANJA CLARO QUIZA HASTA 15-20% (SUBIDA MODERADA), NARANJA OSCURO PARA PENDIENTES HASTA 30-35% (SUBIDA "MEDIA-FUERTE" Y ROJO PARA PENDIENTES FUERTES SUPERIORES AL 35%, (por ejemplo).



Esto podría quizás obtenerse fácilmente si el valor de pendiente máximo de la escala, en lugar de ser fijo del 25% fuera del 35% o 40% e incluso mejor si fuera seleccionable por el usuario.

MEJORAS/NEW FEATURES / Re: Slope colors

After years using this slope color feature for hiking I fully agree that the max slope of 25% is far too low. Most slopes uphill get coloured red, no matter It is a moderate 20% slope or strenuous 50% climb. In the upshot, while hiking you just read the colors as follows:



- various colors green, light blues and orange: almost flat.

- mid orange and blue: mild slope.

- red or dark blue: moderate, strong and strenuous slopes.



That is, 3 colors for flat or almost flat and one single color for mid, strong and very strong slopes!!!



I would propose an additional selectable slope color scale going up to +/- 40%  or, even better, making that max slope parameter value user selectable.
