Fast Access To Fisheries Info With Low-Cost Desktop Software

Reference No:

GIS 24-1

Our agency's most urgent problem is the inability to rapidly locate existing information, some digital, but most still hard copy in files, map cabinets, etc. This presentation illustrates the system that was developed to enter, store, map, query and retrieve geo-referenced information on the fisheries resources of B.C. The approach taken was incremental rather than all encompassing and is described in detail. Design and development were carried out by existing staff (biologists and technicians) using QUIKMap, a locally developed desktop mapping package that retails for less than $1,000.

Carrying Capacity Analysis using GIS

Reference No:

GIS 24-2

This presentation discusses the successful use and role of GIS-ILWIS software in determining conceptually the carrying capacity of the Upper Komering Sub Watershed for rice and coffee cultivation.

The carrying capacity was viewed and determined by the attractiveness of the land for cultivation, identified as a push factor of the farmer to expand and cultivate their land. Therefore, it determines the trend of the supply and demand for land ratio. The attractiveness was considered as the function of the supply of land and it was obtained by combining the physical suitability and socio-economic aspects, i.e. the availability of physical infrastructure of the area and projected into different scenarios.

Global and Regional Priorities for Rain Forest Conservation

Reference No:

GIS 24-3

Information on the global or regional status of temperate rain forests is sparse. This presentation describes the development of a prototype GIS database for one region, the north Pacific coast of North America, with the purpose of establishing regional priorities for temperate rain forest conservation. The methodology used in identifying priority watersheds, issues involved in the development of a regional database which encompasses numerous jurisdictions, as well as future application of this prototype to other coastal temperate rain forest regions, are discussed.

Evaluating Agricultural Forest Management And Environmental Quality

Reference No:

GIS 24-4

This presentation discusses the results of a study designed to evaluate the contribution of conservation treatment and agricultural forests in maintaining environmental quality. The study explored the usefulness of a creating a multipurpose LIS and linking it to a water quality assessment model for evaluating existing and pending land management policies. The model estimates soil erosion at the individual farm field level and calculates sediment delivery based on surface water flow between individual farms fields. Agricultural use scenarios were developed, modeled, and evaluated to determine the environmental outcomes associated with each scenario.

Stream Drainage Patterns and GIS

Reference No:

GIS 24-5

The delineation of geologic faults and fractures is critical for a number of environmental and natural resource management applications. WSU, in conjunction with Pacific Northwest Laboratory, is generating a three-dimensional (3D) GIS tool, Geologic Spatial Analysis (GSA), designed to automatically identify geologic fractures using a wide variety of data bases, including but not limited to digital elevation models (DEMs), remote sensing images, gravity and magnetic data, subsurface geologic information, and earthquake foci. Surface traces of fracture systems as well as 3D models are produced. The result is a computer automated 3D delineation of the location and orientation of major geologic faults and fracture systems in a study area. These can be directly utilized in resource management and environmental applications.

Neural Nets and Genetic Algorithms for State Park Management

Reference No:

GIS 24-6

As the sophistication in the decision-making process increases, what is required is the inclusion of intelligence into the sophisticated modeling structure that allows for multiple decision-making and concurrent adaption to evolving conditions. In addition, methods must be developed to effectively include the public as a resource and subsequently public values into the park management process. This presentation describes a prototype decision-support system for multi-objective state park management using neural network and genetic algorithm technology. This paper examines and contrasts how the resources of Mounds State Park in Indiana are currently being managed, how the park according to State policy is supposed to be managed and, more importantly, how the public perceives the resource management of the park. By understanding how the experts manage the park and contrasting how the public perceive such management objectives, the net and GA based model provides the resource managers with a tool to examine conflicts and tradeoffs over time for long-term planning and management strategies which incorporate public values. Differences between traditional GIS and neural network/GA approaches are presented.

Application Program Interfaces for GIS: A Case Study

Reference No:

GIS 24-7

Vendors have been largely unable to offer generic problem solving tools and users are unable to adapt current packages to their specific applications. In a move to enable users to develop their own analytical modules, some vendors will soon be offering application program interfaces (API). An API for GIS consists of a library of routines for managing and displaying spatial data and associated attributes. These routines are called through and incorporated into programs written in standard programming languages, such as C or Fortran. With a proper API, programming expertise and knowledge of applicable solution techniques users can develop systems to help solve application-specific problems.

Inexact Spatial Reasoning in GIS

Reference No:

GIS 24-8

This presentation describes research in GIS spatial analysis subject to the presence of uncertainty. Two sources of uncertainty are considered: the uncertainty which exists within the spatial data; and the uncertainty in the constraints imposed on an analysis operation. The spatial analysis operations under consideration are the class of spatial relationships related to proximity. A point data structure which embodies uncertainty is defined. Next a heuristic for measuring distance to an inexact point is defined. From this base we show how GIS queries which contain elastic constraints can be evaluated for an area and a new database layer created which represents the degree of conformity of the area to the query.
