This report is willing to give an overview of the situation regarding the geo-referencing of BIM models in GIS. The focus is made on identifying how the geographic coordinates of a construction project shall be integrated in its 3D model such that the information is kept in the context of a GIS application. We study the case of BIMs designed using the Autodesk Revit software and exported as IFC...

The notion of a cartogram is reviewed. Then, based on a presentation from the 1960’s, a direct and simple introduction is given to the design of a computer algorithm for the construction of contiguous value-by-area cartograms. As an example a table of latitude/longitude to rectangular plane coordinates is included for a cartogram of the United States, along with Tissot’s measures for this map p...

Toponym disambiguation or location names resolution is a critical task in unstructured text, articles or documents. Our research explores how to link ambiguous locations mentioned in documents, news and articles with latitude/longitude coordinates. We designed an evaluation system for toponym disambiguation based on annotated GEOCLEF data. We implemented a node-based approach taking population ...

bamdezh wetland with the geographical coordinates of   north longitude, east latitude and an area of 44 square kilometers, is located in about 40 km northwest of ahvaz and shavur river is the main source of its supply. this wetland is not only a habitat and suitable food source for aquatic and migratory birds, but as well a significant resource of income for the locals. today, with the arrival ...

Error in radar satellite orbit determination is a common problem in radar interferometry (INSAR). For example, when we try to locate a radar test site with known geographic coordinates using the geocoding information in SLC (the latitude and longitude of the four image corners), the location is well away from the true position. Another example is when there is a significant disturbance in the d...

High-latitude plants are often more palatable to herbivores than low-latitude conspecifics. Does increased plant palatability lead to better herbivore performance? Our field and laboratory work investigated (A) whether high-latitude plants have traits indicating that they should be higher-quality foods for herbivores; (B) whether geographic differences in plant quality are more important than l...

This work presents a survey of the current state of the art of visualization techniques for parallel coordinates. It covers geometric models for constructing parallel coordinates and reviews methods for creating and understanding visual representations of parallel coordinates. The classification of these methods is based on a taxonomy that was established from the literature and is aimed at gui...

In this paper we will discuss local coordinates canonically corresponding to a Kähler metric. We will also discuss the C ∞ convergence of Bergman metrics following Tian's result on C 2 convergence of Bergman metrics. At the end we present an interesting characterization of ample line bundle that could be useful in arithmetic geometry.

Observations of Titan's mid-latitude clouds from the W. M. Keck and Gemini Observatories show that they cluster near 350 degrees W longitude, 40 degrees S latitude. These clouds cannot be explained by a seasonal shift in global circulation and thus presumably reflect a mechanism on Titan such as geysering or cryovolcanism in this region. The rate of volatile release necessary to trigger cloud f...
