This article reports on a bidirectional link between a Geographic Information System (GIS), ArcView 2.1, and an interactive dynamic graphics program, XGobi. ArcView 2.1 allows calls to external procedures via Remote Procedure Calls (RPCs) and it also enables external programs to invoke ArcView 2.1 functions using RPCs. These features enable us to provide a bidirectional link between ArcView 2.1...

In an accompanying paper, we describe an implementation of a smoothed conditional mapping system, which we have implemented in arcview. Due to space limitations in that paper, we included only a small fraction of the possible cancer-related graphs based upon the SEER collection. In this demonstration, we will make available our arcview software add-ons, and demonstrate its performance with real...

The dynamic link among the Geographic Information System (GIS) ArcView, the dynamic statistical graphics (DSG) program XGobi, and the statistical computing environment XploRe has been successfully used to explore and analyze all kinds of spatially referenced data | from forest health data over precipitation data to precision agricultural data. In this paper, we will focus on the exploration of ...

This paper describes the functionality and architecture of SpaceStat, the SpaceStat Extension for ArcView and the DynESDA Extension for ArcView. It compares the features of these packages to five other software implementations for spatial data analysis. Some ideas are formulated on generic requirements and future directions pertaining to computing environments for spatial data analysis.

The ordinary GIS systems use command line, menu or window interface, which are difficult for a naïve user to use. In this paper, SNePS (the Semantic Network Processing System) is used to represent geographic spatial knowledge. An intelligent naturallanguage interface between ArcView and SNePS (the Semantic Network Processing System) was implemented. The interface will accept the input command a...

To study the relationship between deep groundwater productivity and lineament, we use several lineament maps which are lineament map, lineament length density map, lineament cross-point density map and others from Remote Sensing. The avenue script files for calculating the lineament statistics, the lineament length density, lineament cross-point density value and the distance between a groundwa...

This paper reports on research into interactive, dynamic statistical graphics (DSG) applied to spatial data maintained within a geographic information system (GIS). We developed a bidirectional link between ArcView 2.1TM, a GIS, and XGobi, a DSG program. Multivariate data, collected at geographic locations, is passed from ArcView to XGobi and can be dynamically analyzed. The relation between th...

BACKGROUND: Learning the exact demographic characteristics of a neighborhood in which a public library serves, assists the collection development librarian in building an appropriate collection. Gathering that demographic information can be a lengthy process, and then formatting the information for the neighborhood in question becomes arduous.As society ages and the methods for health care evol...
