Abstract An algorithm is presented to calculate the point on the surface of a sphere maximising the great-circle distance to a given spherical polygon. This is used to calculate the spots furthest from the sea in major land masses, also known as Poles of Inaccessibility (PIA), a concept that has raised the interest of explorers. For the Eurasian pole of inaccessibility (EPIA), the results reveal a misplacement in previous calculations ranging from 156 to 435 km. Although in general there is… 
Finding Antarctica’s Pole of Inaccessibility
Abstract Antarctica’s Pole of Inaccessibility (Southern Pole of Inaccessibility (SPI)) is the point on the Antarctic continent farthest from its edge. Existing literature exhibits disagreement over
An algorithm for maximum inscribed circle based on Voronoi diagrams and geometrical properties
The algorithm developed in this study (MICGIS) for the computation of MIC can be applied to both convex and concave polygons represented in vector data format and is both faster and more accurate in finding MIC compared with the alternative algorithms and software.
Optimal orientations of discrete global grids and the Poles of Inaccessibility
This study presents an algorithm for finding suitable orientations for polyhedra, and shows that Fuller's Dymaxion map corresponds closely to one of the optimal orientations it finds.
An Efficient Algorithm to Calculate the Center of the Biggest Inscribed Circle in an Irregular Polygon
An efficient algorithm to find the center of the biggest circle inscribed in a given polygon is described, inspired by the publication of Daniel Garcia-Castellanos & Umberto Lombardo and their algorithm used to find a landmass' poles of inaccessibility.
Center of a Territory: Definitions and Methods. The Case of Italy
It has analyzed the concept of 'center of a territory', highlighting the problems associated with the difficulty in defining what part of the territory should be taken into consideration and the
Potential and Limitations of Satellite Altimetry Constellations for Monitoring Surface Water Storage Changes - A Case Study in the Mississippi Basin
This study investigates the potential and limitations of past and current satellite missions for the monitoring of basin-wide storage changes in the Mississippi River Basin and reveals that the current altimeter configuration misses about 80% of all lakes larger than 0.1 km2 in the MRB.
Finding the Arctic pole of inaccessibility
ABSTRACT The Arctic pole of inaccessibility (API), defined as the point on the Arctic Ocean that is farthest from any land, is commonly asserted to lie at 84° 03′ N, 174° 51′ W. We show that the true
Building detection in off-nidar very high resolution satellite images based on stereo 3D information
This paper proposes a registration method based on developing a line-of-sight DSM solution to effectively register elevation data for co registering offnadir VHR satellite imagery with elevation data.
Treeing the CATS: Artificial Gulf Formation by the Chotts Algeria–Tunisia Scheme
The Chotts Algeria–Tunisia Scheme (CATS) is a grand design to form a manexcavated new Mediterranean Sea gulf to be shared by Tunisia and Algeria. It is well known that closed and nearly closed
Geometric methods for estimating representative sidewalk widths applied to Vienna’s streetscape surfaces database
This paper presents three novel methods for estimating representative sidewalk widths and applies them to the official Viennese streetscape surface database and discusses possible applications of these methods for monitoring and regression analysis.


Role of sintering in snow construction
Antarctic science and conservation — The historical background
A global, self‐consistent, hierarchical, high‐resolution shoreline database
A high-resolution shoreline data set amalgamated from two databases in the public domain, which has undergone extensive processing and is free of internal inconsistencies such as erratic points and crossing segments is presented.
