Distributed Server Programming using .Net and ArcObjects Track: Application Development Author(s): Brian Flood This paper explores the use of both .Net and ArcObjects in the Programmable Mapping Cluster (PMC), a software framework to ease ArcObjects development over large groups of servers. The PMC makes extensive use of the .Net Remoting architecture to connect all servers in a cluster into a ...

This paper presents an overview of some of the research performed at the Bureau of Reclamation, Mid-Pacific GIS Service Center over the past two years related to the application of ArcObjects technology involving hydrodynamic modeling. Topics include finite element mesh generation and the representation of mesh components as a geometric network, construction of 3D fence diagrams in applications...

This paper presents algorithmic components and corresponding software routines for extracting shoreline features from remote sensing imagery and LiDAR data. Conceptually, shoreline features are treated as boundary lines between land objects and water objects. Numerical algorithms have been identified and devised to segment and classify remote sensing imagery and LiDAR data into land and water p...

In an urban environment, the occlusion of satellite broadcasts varies across space and thus, preplanning for collection of GPS points requires consideration of these obstructions. This paper presents a GIS embedded model (ArcGIS and ArcObjects) for predicting GPS error via modeling PDOP in an urban environment. The "skyview" model predicted PDOP for spatial locations as a function of the percen...

This paper discusses the provision of GIS to non-GIS users. Intelligence plays a vital role in combating not only international terrorism but also domestic crimes. In order to explore the full potential of the intelligence materials available, GIS technology shall be made more accessible to non-GIS users, such as frontline police officers and other law enforcement agents. A standalone police/se...

This article presents a new generalization algorithm for automated or semi automated buildings simplification based on the recursive approach. From the data set with a higher level of detail another data set that containing a lower level of detail can be derived. The proposed algorithm has an ability to detect and simplify buildings rotated in random position and does not depend on ordering of ...

Historic aerial photos are typically very popular, sought-after collections in library archives. Their ability to be used in GIS is limited, however, by the laborious and painstaking georeferencing process. A method is presented for automating the georeferencing of historic aerial photography. In this method, the Harris Corner Detector is used to detect corner points in already-georeferenced an...

Many decision tasks in disaster management are concerned with spatial patterns and spatial decision problems often require that a large number of feasible alternatives be evaluated based on multiple criteria. Although Geographical Information Systems (GIS) provide extensive spatial analysis and data visualization power to users, such systems offer a limited capacity for tackling complex spatial...
