Sc\u00e9nario :<\/strong>
\nUn ami vous lance un d\u00e9fi. A partir de diff\u00e9rentes photos prises lors d\u2019une croisi\u00e8re en bateau qu\u2019il a effectu\u00e9, vous aller devoir retrouver les lieux o\u00f9 les photos ont \u00e9t\u00e9 prises ainsi que l\u2019ordre dans lequel le voyage s\u2019est d\u00e9roul\u00e9.
\nPour atteindre cet objectif, vous allez devoir rechercher les informations utiles dans chaque photo (les metadonn\u00e9es EXIF).
\nUn v\u00e9ritable travail d\u2019enqu\u00eateur vous attend !<\/p>\n

1\u00b0\/ C\u2019est quoi les donn\u00e9es EXIF ?<\/strong>
\nLes donn\u00e9es EXIF (Exchangeable Image File Format) sont des informations cach\u00e9es que les appareils photo et les smartphones enregistrent automatiquement quand on prend une photo.
\nUne d\u00e9finition simple :
\n\ud83d\udc49 Les donn\u00e9es EXIF sont comme une carte d\u2019identit\u00e9 de la photo. Elles indiquent par exemple la date et l\u2019heure de la prise de vue,
\nl\u2019endroit (si le GPS est activ\u00e9), le type d\u2019appareil utilis\u00e9, ou encore si le flash a \u00e9t\u00e9 utilis\u00e9.<\/p>\n

2\u00b0\/ Retrouver les donn\u00e9es de chaque photo en utilisant la m\u00e9thode suivante.<\/strong>
\n\u2022 Ouvrir le dossier contenant les photos prises par votre ami dans “espaces des classes”, ” documents en consultation”
\n\u2022 Faire un clic-droit sur une photo et s\u00e9lectionner \u00ab propri\u00e9t\u00e9s \u00bb en bas du menu puis \u00ab d\u00e9tails \u00bb<\/p>\n

\"\"<\/a><\/p>\n

3\u00b0\/ A partir des diff\u00e9rentes donn\u00e9es :<\/strong>
\n– compl\u00e9tez le tableau suivant en vous aidant aussi du site \u00ab https:\/\/www.coordonnees-gps.fr\/ \u00bb ;
\n– Placer sur la carte le lieu de la prise de vue par un point \u00ab \u2022 \u00bb ainsi que le nom du lieu.<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\n(Point \u00e0 placer sur la carte ainsi que le nom du lieu s\u2019il n\u2019est pas pr\u00e9sent)<\/p>\n

\"\"<\/a><\/p>\n

4\u00b0\/ En vous servant des dates de prises de vue, tracez le parcours en reliant les diff\u00e9rents lieux par un trait et en les num\u00e9rotant dans l\u2019ordre chronologique.<\/strong><\/p>\n

5\u00b0\/ En quoi les donn\u00e9es EXIF peuvent-elles \u00eatre dangereuses \u00e0 votre avis ?<\/strong>
