Hiking begins even before walking, as we find out the route on the map. A detailed reading of it will provide all the information on what walkers can expect, hence it is a useful and important tool.
A map shows the terrain only on a horizontal plane, seen from the sky, minimised and schematised . It takes a little training to establish the relationship between the map and terrain. You can’t read it too quickly. Whether it's to prepare for a hike or to get a sense of direction, your map will always be there to help you, and unlike GPS and mobile phones, it won’t fail. Think of bringing a compass so you never miss the north direction.
For hiking, the ideal scale is 1/25 000; that is, 1 cm is equivalent to 250 m, or 4 cm for 1 km. It allows you to see every detail (streams, forests, trails ...) and to obtain a precise sense of location. These scales correspond to IGN Blue Series Maps and TOP25 maps. For those who hike in the rain, there are TOP25R maps ("R" for "Resistant"), waterproof, tear proof and printed double-sided to save space on your bag.
Green
Indicates wooded areas
White
Indicates meadows and cultivated areas
Orange
Generally indicates contours
Blue
Indicates hydrography elements (lakes, rivers ...)
Black
It is widely used and refers to everything that comes from human intervention; it also indicates rocks and scree
You will see areas that are more or less darkened. Shaded areas on slopes or hillsides give the impression of a relief. By convention, theoretical light mapping is determined as if the sun illuminated the ground from the North West (with an average angle of 45°). This fact is not an element of orientation, it is simply a tool to facilitate the perception of a relief when reading the map.
Details often make it possible to determine one's location in a very precise way.~
By convention, the north is located at the top of the map.~
