The scene is therefore located somewhere within the territory of Plzeň. In the third part of my investigation, I focus on methods that will serve as the basis for the final selection within the city area.
>3.1 - Prediction of the ground plan (sketch)
>3.2 - Position of the sun and cast shadows
The goal of this phase is to use various parameters to eliminate as much of Plzeň’s area as possible, and drastically narrow down the territory that needs to be later searched using Google Maps.

Součástí projektu se taktéž stala skica půdorysu, kterou jsem v průběhu pátrání vykreslil. Zaznamenává veškeré body a objekty, které již znám a vím, kde se ve scéně nachází. Zároveň skica funguje jako moje predikce půdorysu (satelitní pohled) dané ulice. Předpovídám zde na základě informací získaných z archivovaných záběrů, jak je pravděpodobně rozložen mně neviditelný zbytek ulice.
Tato skica taktéž hraje roli i přímo při geolokaci scény. Při prohlížení plzeňských ulic pomocí satelitních snímků Google Maps pomáhá vizualizovat, jakým způsobem ulice může vypadat shora a tím opět ulehčit pátrání v mapách.
At this point, the main tool for me has become the position of the sun and the cast shadows that appear in the scene. Over the course of a single day, I recorded several shadow positions cast by an adjacent building onto the walls of the garages.
By combining several images, my sketch, and the software from the website suncalc.org, I evaluate which cardinal direction the street in the scene faces. Determining this orientation later becomes a useful element, allowing me to eliminate a large portion of non-matching city districts.
