This paper introduces the universal mobile interface that allows users to navigate themselves into multiple heterogeneous digital cites with a single interface. The universal mobile interface connects a map-based information search system, an image-based virtual city space, and a 3D virtual city space, that had been developed independently. A user can walk-through the above systems simultaneous...

“a city can be read through its streets”. stéphane douady, professor of dynamics of out-of-equilibrium systems in paris diderot university began his speech with these words. he continued by explaining the significance of the street structure: “when we think of a city, we first think of the houses. while they can be replaced when destroyed or abandoned, the streets remain stable”. dr. douady’s m...

Objective: The aim of this study is to provide a management plan for the Sykan watershed of Darre shahr city located in Ilam province using GIS in land use planning. Methods: For land using of Sykan watershed of Ilam province with about 9 hectares area, map of classes, elevation, percent slope, geographical aspects, soil characteristics, vegetation density and the final map units were combined ...

This research evidences the usefulness of open big data to map mobility patterns in a medium-sized city. Motivated by the novel analysis that big data allow worldwide and in large metropolitan areas, we developed a methodology aiming to complement origin-destination surveys with à la carte spatial boundaries and updated data at a minimum cost. This paper validates the use of Twitter data to map...

This paper targets the construction of pedestrian maps for city-scale events from GPS trajectories of visitors. Incomplete data with a short lifetime, varying localisation accuracy, and a high variation of walking behaviour render the extraction of a pedestrian map from crowd-sourced data a difficult task. Traditional network or map construction methods lean on accurate GPS trajectories typical...

Qs Sand Wind-blown sand blankets a number of areas in the western part of the quadrangle. These well-sorted, mediumto fine-grained quartzose sands are commonly deposited on the east to northeast sides of hills but may extend across some flat areas. The sands are uncemented and loose but most are well stabilized by vegetation, locally including trees. The sands are usually white to tan but local...

Virtual reality applications in the context of urban planning presume the acquisition of 3D urban models. Photo realism can only be achieved, if the geometry of buildings is represented by a detailed and accurate CAD model and if additionally arti cial texture or real world imagery is mapped to the faces and roofs of the buildings. In the approach presented in this paper, height data provided b...
