- Challenge Link: [Czechia - Fix Spiky Buildings](<a href="https://maproulette.org/browse/challenges/51761" data-outlook-id="dba96f9b-2753-41be-b8cf-d913cc07fd04">https://maproulette.org/browse/challenges/51761</a>)</div>
<div class="gmail_quote" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
- Goal: This challenge targets buildings with potentially inaccurate geometry, specifically those featuring very sharp angles (less than 15 degrees between walls meeting at a node). While most building corners are near 90 degrees, these sharp angles often indicate
mapping errors.</div>
<div class="gmail_quote" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
- Why it matters: Accurate building shapes are crucial for urban planning, emergency response, navigation, and overall map quality and aesthetics.</div>
<div class="gmail_quote" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
- How tasks were created: TomTom identified building geometries where the angle between two connected walls at a node is less than 15 degrees.</div>
<div class="gmail_quote" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
- Important Note: Some buildings genuinely have sharp angles due to design (e.g., historical or unique architecture) or might represent combined multi-part buildings. Please investigate carefully and mark tasks as "Not an Issue" if the geometry accurately reflects
reality.</div>

- Cíl: Tato výzva se zaměřuje na budovy s potenciálně nepřesnou geometrií, konkrétně na ty, které mají velmi ostré úhly (méně než 15 stupňů mezi stěnami, které se setkávají v uzlu). Zatímco většina rohů budov má úhly blízké 90 stupňům, tyto ostré úhly často
naznačují chyby při mapování.</div>
<div class="gmail_quote" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
- Proč je to důležité: Přesné tvary budov jsou klíčové pro městské plánování, záchranné služby, navigaci a celkovou kvalitu a estetiku mapy.</div>
<div class="gmail_quote" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
- Jak byly úkoly vytvořeny: Společnost TomTom identifikovala geometrie budov, kde úhel mezi dvěma propojenými stěnami v uzlu je menší než 15 stupňů.</div>
<div class="gmail_quote" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
- Důležité upozornění: Některé budovy mohou mít ostré úhly kvůli designu (např. historická nebo unikátní architektura) nebo mohou představovat kombinované vícedílné budovy. Prosím, pečlivě prozkoumejte a označte úkoly jako „Není problém“, pokud geometrie přesně
odráží realitu.</div>
