Geographic information system (GIS) technology has been applied to analyze the offshore marine placer gold deposits at Nome, Alaska. Two geodatabases, namely Integrated Geodatabase (IG) and Regularized 2.5D Geodatabase (R2.5DG), were created to store and integrate digital data sets in heterogeneous formats. The IG served as a data warehouse and used to manage various geological data, such as bo...

Describing the quality of digital geodata in a geodatabase is required for many applications. We present our developments for automated quality control of the area-wide available topographic vector data set ATKIS in Germany using images. To reach an efficient solution our concept is designed as an automated system, which comprises automatic cartographic feature extraction and comparison with AT...

According to the research of problem of data conversion from AutoCAD to GIS, this paper analyzes the characteristics of AutoCAD data and GIS data, and finds out the comparison relationship of graphic data conversion from AutoCAD to GIS. With the aid of the component libraries of ArcEngine and ObjectARX, the research implements the graphic data conversion using c # language in .NET environment, ...

The concept of the GIS as a centralized enterprise asset rather than a cartographic tool is gaining acceptance. Enterprise GIS takes an organizational approach for sharing and managing spatial information. At Otay Water District, we are integrating the departmental projects and data into a centralized GIS. A series of interviews was conducted within the District to make sure the new GIS system ...

This paper describes the use of ArcGIS and the 3D Analyst extension for the integration of multiple petroleum datasets as part of research undertaken by the University of Newcastle upon Tyne, UK, on behalf of Shell International Exploration and Production. The integration of datasets from both surface and subsurface application areas is essential to present a complete picture for decision-makin...

The steps required to migrate to geodatabase technology are different for each organization. This session will discuss how ArcMap extensions can ease this transition by enabling mapping professionals to continue using tools they are familiar with. Comprehensive ArcMap extensions give users tools to perform mapping functions such as parcel splits and merges, annotation, CAD file import and manip...

Assets and the associated data is a key component in making planning and capital improvement decisions for a water district. This paper describes the implementation of the Soquel Creek Water District's Enterprise GIS system using ArcIMS, ArcMap Server, Geodatabase, and the .NET technology. ArcIMS Web Services are used to provide a common interface to different class of users (e.g., Customer Ser...
