A Contour Line Group Simplification Method Based on Classified Terrain Features [PDF]

ISPRS International Journal of Geo-Information, 2023
Contour line group simplification methods can effectively preserve terrain features during map making and producing. This process involves two main steps, namely terrain feature line extraction and contour bend selection.

A Similarity Metric Method for Contour Line Groups Considering Terrain Features [PDF]

ISPRS International Journal of Geo-Information
Contour lines, as the primary elements of fundamental geospatial data, have long been a research focus for similarity measurement. With the evolution of cartographic generalization, the representation of contour lines across varying scales must maintain ...

Extreme response estimation of offshore wind turbines with an extended contour-line method [PDF]

Journal of Physics: Conference Series, 2018
The contour-line method is a simplified approach for finding the long-term extreme values by a small number of short-term analyses. It is assumed the response with a return period of T years occurs during a sea-state with a shorter or equal return period.

A contour line of the continuum Gaussian free field [PDF]

, 2010
Consider an instance $$h$$ of the Gaussian free field on a simply connected planar domain $$D$$ with boundary conditions $$-\lambda $$ on one boundary arc and $$\lambda $$ on the complementary arc, where $$\lambda $$ is the special constant $$\sqrt{\pi ...

Penerapan Contour Detection dengan Pengontrol PID pada Robot Line Follower

Jurnal Elkomika
ABSTRAK Sebuah robot line follower harus mampu mendeteksi garis dan bergerak mengikuti garis tersebut. Warna garis dan lantai yang tidak begitu kontras satu sama lain cukup sulit untuk dibedakan.

Skeleton Based Contour Line Generalization

, 2006
Contour lines are a widely utilized representation of terrain models in both cartography and Geographical Information Systems (GIS). Since they are often presented at different scales there is a need for generalization techniques. In this paper an algorithm for the generalization of contour lines based on skeleton pruning is presented. The algorithm is
