3D visualization has become the basic requirements of many applications of GIS. However, most of the commercialization of GIS software based on two-dimensional, to describe the true three-dimensional hydraulic engineering environment. Data integration with 3D visualization technology can be obtained through various means in order to visualize three-dimensional graphics dynamically shown to provide a convenient analytical tool to handle the vast amounts of complex engineering data, has become the GIS research cutting edge of technology and research hotspot. This paper first discusses the hydraulic engineering 3D visualization modeling framework and then study the water conservancy 3D GIS model and visualize the general principles and processes. And the general approach and application effect of 3D GIS Model have been illustrated in detailed.

In this paper, a novel approach of building damaged detection is proposed using high resolution remote sensing images and 3D GIS-Model data. Traditional building damage detection method considers to detect damaged building due to earthquake, but little attention has been paid to analyze various building damaged types(e.g., trivial damaged, severely damaged and totally collapsed.) Therefore, we want to detect the different building damaged type using 2D and 3D feature of scenes because the real world we live in is a 3D space. The proposed method generalizes that the image geometric correction method firstly corrects the post-disasters remote sensing image using the 3D GIS model or RPC parameters, then detects the different building damaged types using the change of the height and area between the pre- and post-disasters and the texture feature of post-disasters. The results, evaluated on a selected study site of the Beichuan earthquake ruins, Sichuan, show that this method is feasible and effective in building damage detection. It has also shown that the proposed method is easily applicable and well suited for rapid damage assessment after natural disasters.

Modeling Data

The main topic of this article is the architecture modeling data which is involved in 3D GIS. The constructing platform of modeling data is also discussed. Then, it makes comparison and analysis between these platforms. Comparing to other platforms, SketchUp has lots of advantages, such as easy to operate, good for effect, saving storage space and cross-platform. So it has been used for feature modeling in 3D-GIS area, and it can satisfy the demand of this domain. At last, combining with the practical engineering, the article discusses the modeling method using the SketchUp software. The results are desired, and the method is worth to extend.

This article is a case study in doing new things with old data. In 1953 Lord William Taylour directed the excavation of a monumental vaulted tholos tomb known as 'Tholos IV' at the site of ancient Pylos, Messenia, Greece. The excavation was conducted over two months, during which detailed notes were recorded in three notebooks now kept in the Archives of the American School of Classical Studies at Athens. The formal publication of Tholos IV, however, contains only a basic narrative of the excavation, offering neither precise detail on stratigraphy, object find spots, nor even a complete inventory of small finds. The present study goes back to the original notebooks kept by Taylour and combines the data contained in them with a new digital survey of Tholos IV to produce a comprehensive and accurate 3D GIS model for the excavation. Furthermore, the GIS has been produced in such a way that its dataset is compatible with new excavation data currently generated in the ongoing Palace of Nestor Excavations (PONEX) project, bringing together two excavation campaigns conducted under very different circumstances, methodologies, and recording protocols. Discussion follows on how the production of this GIS deepens our understanding not just of the legacy excavation, but also of the site and its wider landscape.
