A novel approach of Model-based Building Reconstruction (MBBR) from topographic maps and LiDAR data called Floating Models is proposed in this paper. Floating models are a series of pre-defined primitive models which are floating in the space. Its size is adjustable by shape parameters, while its location and rotation is controlled by pose parameters. A building is reconstructed by adjusting th...

Land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion, sedimentation and soil conditions. Decreasing of forest area in the North of Iran is one of the critical problems in recent years. The aims of this study are to detect land use changes between 1967 to 2002 using satellite images of Land Sat 7 ETM (2002), aerial photos and digital topog...

We study platform owner’s decision to enter the market complementary to its platform with its own rival complement, and the consequences of such an entry on complementors’ innovation behavior. We ask: if a platform owner like Google releases an app for its Android platform, does it keep app developers from innovating in the future? We investigate two mechanisms that suggest entry to stimulate c...

Over the last four decades Geographical Information Systems (GIS) have emerged as the predominant medium for graphic representation of geospatial data, including geotechnical, geologic and hydrologic information routinely used by geotechnical and geoenvironmental engineers. GIS allow unlimited forms of spatial data to be co-mingled, weighted and sorted with any number of physical or environment...

With the explosion in the number of images and videos on the Internet and ongoing amassing of huge volumes of visual data from digital cameras and mobile devices, we are unknowingly logging our own history. Consider that the number of digital cameras and camera phones in the world has surpassed one billion and that 500 billion consumer photos are taken each year. Given the world’s population of...

Optical remote sensing data have been considered to display signal saturation phenomena in regions of high aboveground biomass (AGB) and multi-storied forest canopies. However, some recent studies using texture indices derived from optical remote sensing data via the Fourier-based textural ordination (FOTO) approach have provided promising results without saturation problems for some tropical f...

Two kinds of method, raster fusion and vector fusion, is proposed for fusion operation by integration of LIDAR point cloud and Ortho aerial photos in this paper. The data set used in the paper and data process for preparation is introduced firstly. In order to complement the raster fusion, the points cloud is interpolated into a raster style by Inverse Distance Weighted(IDW) method using Z and ...

Remotely sensed data offer a global coverage, with variable spatial, radiometric, spectral and temporal resolutions, and are the major source of geo-spatial information. The importance of cities and their structural complexity and continuous change make the use of such data even more necessary. In this chapter, we will limit ourselves to remote sensors that can facilitate the extraction of basi...

In this paper, a new smooth slideshow transition effect, Sewing Photos, is proposed while considering both of smooth content transition and smooth camera motion. Comparing to the traditional photo browsing and displaying work, which all focused on presenting splendid visual effects, Sewing Photos emphasizes on the smooth transition process between photos while taking the photo contents into acc...
