Interaction with GIS Attribute Data Based on Categorial Coverages
نویسندگان
چکیده
The human-computer interface is a crucial element in the design of the next generation of Geographic Information Systems (GISs). We discuss the user interface design process by separating the formalization of the problem domain (identifying the objects a user manipulates, and their pertinent operations) from its visualization (describing human-computer interaction techniques such as windows and dialog boxes). This framework is used to examine the process of manipulating attribute data in a GIS on the basis of the common cartographic concept of a categorical coverage. The characteristics of categorical coverage data and the user requirements for interacting with this data are formalized in the form of a set of fundamental objects and operations. A visualization for a windows-icons-menus-pointing devices (WIMP) interface is presented.

A Framework for Incremental Knowledge Base Update from Additional Data Coverages
The paper describes a methodology for the incremental addition of remotely sensed data layers to a rule-based knowledge model. In particular, it reports on the effects of the addition of an Electromagnetic (EM31) layer to an existing GIS database consisting of groundwater depth, soil type, geology, slope, elevation, and the seven (7) spectral bands of Landsat TM. A field survey recharge coverag...
متن کاملFormalization of Families of Categorical Coverages
Categorical coverages are popular for the presentation of thematic data in cartographic form and have gained widespread use. Routines for their preparation are included in most GIS software. Categorical coverages are simple to implement and easy to understand. The popularity of the categorical coverage is closely related to the intuitive rules that determine its behavior. This paper presents a ...

Implementation of Simple Object Access Protocol (SOAP)-based Web services within a collection of classes GSfM (GIS Support for MCCM) is presented. GSfM facilitates the provision of various geographical and tabular input data into the MCCM (Multiscale Chemistry Climate Model). The classes have been written in object-oriented Perl. They allow to write simple Perl scripts and to perform data provi...
متن کاملInvestigating GIS and Smoothing for Maximum Entropy Taggers
This paper investigates two elements of Maximum Entropy tagging: the use of a correction feature in the Generalised Iterative Scaling (Gis) estimation algorithm, and techniques for model smoothing. We show analytically and empirically that the correction feature, assumed to be required for the correctness of GIS, is unnecessary. We also explore the use of a Gaussian prior and a simple cutoff fo...
متن کاملInstitutional mapping of Oregon coastal watershed management options
Institutional mapping is a technique that builds on the logic of Geographic Information Systems (GIS). In GIS, coverages placed over a base map show spatial relations. Social institutions are more difficult to ‘‘map’’ physically. Institutional mapping uses three social coverages—scale, power, and capital. Four sets of institutions affecting watershed management—salmon restoration, water quality...
