Wrong drawing poligons on minor zoom.

Reported by: evgen_ru Owned by: cp15
Priority: major Milestone: version 0.5.2
Component: graphics/gtk_drawing Version: git master
Severity: Keywords: generalisation, buildings

Description (last modified by usul)

If the city is at home, reducing their need to hide. Because when you hide a half points in a polygon, they look very bad and do not carry useful information.

Enclose a map view by default.

good view of polygon wring draw of poligon

In our city, marked by almost all the houses and they look they are very, very bad for a small increase.


Если в городе есть дома, при уменьшении нужно их прятать. Так как при скрытии половины точек в полигонах они выглядят очень плохо и не несут полезной информации.

Прикладываю вид карты по умолчанию.

В нашем городе отмечены почти все дома и выглядят они они очень-очень плохо при маленьком увеличении.

  • Keywords generalisation buildings added

This is a bug caused by the current generalisation strategy. Navit tries to simplify geometries by ignoring nodes of a shape, which are to cloth together. As buildings have very regular/orthogonal shapes, the effect there is very drastic.

I can confirm this bug with current SVN on various platforms. There might be related tickets: #1050 , #766
