We developed new measures of structural complexity using single point terrestrial laser scanning (TLS) clouds. These metrics are depth, openness, and isovist. Depth is a three-dimensional, radial measure the visible distance in all directions from plot center. Openness percent scan pulses near-omnidirectional view without return. Isovists measurement area location, quantified viewshed within fo...

krajoliku na prostoru sjevernog i srednjeg Velebita. Posebna pozornost posvećena je lokalitetima koji se u literaturi navode kao središnja naselja zajednica (gradine Kuk u Senju, Gradina u Svetom Jurju i Drvišica u Karlobagu) i njihovim pozicijama u vizualnom krajoliku. Budući da je u dosadašnjoj literaturi istican strateški značaj ovih pozicija, autorica istražuje mogućnosti njihove vizualne k...

This paper discusses using Geographical Information Systems to predict broadband wireless coverage and channel characteristics in the bands between 2.4 and 30 GHz. It presents system layout software that integrates demographic, marketing, and land-use data with digital elevation models (DEM) and Light Detection and Ranging (LIDAR) measurements and compares predicted coverage with measurements a...

As a consequence of increasing safety concerns, camera surveillance has been widely adopted as a way to monitor public spaces. One of the major challenges of camera surveillance is to design an optimal method for camera network placement in order to ensure the greater possible coverage. In addition, this method must consider the landscape of the monitored environment to take into account the ex...

Tourism is one of the most economically important industries. It is, however, vulnerable to disaster events. Geotagged social media data, as one of the forms of volunteered geographic information (VGI), has been widely explored to support the prevention, preparation, and response phases of disaster management, while little effort has been put on the recovery phase. This study develops a scienti...

Site selection is a key factor in any aquaculture operation, affecting both success and sustainability. Moreover, it can solve conflicts between different coastal activities, making a rational use of the coastal space. Geographical information systems (GIS) have become of increased significance for environmental planning and assessment mainly because of the need to compare a great number of spa...
