Внимание: Бележка към темата

The archive holds no official solutions or marking scheme for this Fieldwork Exercise; the printed Map of the FWE-I area and the Response Sheet referred to in the tasks are not part of this file.

Dear iGEO participant,

Before starting your virtual trip of the Sariyer district of Istanbul city, please read these guidelines.

  1. You have the printed Map of the FWE-I area. Use this map to orient yourself and find the location of five topical sites. The sites are marked on the map, but not labelled.
  2. The sequence of moving from one site to another is in numeric order: Site 1 (Start) → Site 2 → Site 3 → Site 4 → Site 5 (Finish).
  3. The absolute height (elevation) at each site is lower than of the previous one on the route. Always go down!
  4. “Leaving” one site and “arriving” at the next one, do not return. Always move forward!
  5. At each site you will get tasks you need to complete. For FWE-I you can gain maximum 15 marks.
  6. You are to decide for how long you will be “staying” at each site.
  7. Answers should be written in English on the Response Sheet. For answers use a pen with a dark blue tint only. Do not forget to write your participant code in the upper right corner of both pages of the Response Sheet.
  8. This presentation will be stopped when 60 minutes end, regardless of whether you have visited all five sites, or not. Deliver your Response Sheet to the supervisor of your exam immediately then.
  9. Keep the Map with you, it can be used as reference for Part II of the Fieldwork exercise (FWE-II).

Good luck!

ARRIVING TO THE STARTING POINT

Imagine you to the Hacıosman metro station (green line), located in the Eastern Thrace, 2 km from the Bosphorus.

Topographic map extract with contour lines (labels 90, 110, 120), green forest areas, orange main roads (Hacı Osman Bayırı Caddesi, Tarabya Bayırı Caddesi, Büyükdere Caddesi) and a junction; a star marks Site 1 just west of the Hacıosman metro station (M symbol); street names Dönence Sokağı, Zambak Sokağı, Çamlık Caddesi and others in the north-east; scale bar 100 m in the lower-left corner.

Site 1 is right across the road from an unfinished building of a hotel.

Analyze the map extract and assuming that each floor of this building is 2.5 meters in height and the terrace on its roof is the same height, answer the questions from the next slide.

Istanbul railway network map (Metro Istanbul, 2021) covering the whole slide: coloured metro, tram, funicular and suburban lines on both sides of the Bosphorus, with the green M2 line running north to its terminus Hacıosman; legends “Mevcut Hatlar / Lines In Operation”, “Yapımı Devam Eden Hatlar / Lines Under Construction”, “İşaretler / Signs”, “Bilgilendirme / Information”, “İletişim / Contact”. The task text “ARRIVING TO THE STARTING POINT …” is printed over the top-left corner of the map.

1.B. Estimate the difference (in meters) of the height of this building and the pillars of the highest bridge over The Bosphorus.

Write your answers on the Response Sheet and move to the next site.
