Using Geographic Information System (Gis) In A Local Government--A Case Study Of Gis Implementation In Ascension Parish Government, Louisiana, Hongwei Zhao
LSU Master's Theses
The objective of this paper is to argue for a new model of Geographic Information System (GIS) implementation, Web-based GIS, for supporting decision-making in local government. In this paper, the GIS implementation in Ascension Parish Government, Louisiana is used as a case study to show how Web-based GIS implementation can improve the system use and maximize the value of GIS infrastructures for the community. The author first defines the concept of implementation and role of GIS in local government as a base for further discussion. Special attention is given to analyze the variables that influence the parish employees’ acceptance and …
Spatial Models Of Hawaiian Streams And Hawaiian Stream Fish Habital, James Elliott Parham
Spatial Models Of Hawaiian Streams And Hawaiian Stream Fish Habital, James Elliott Parham
LSU Doctoral Dissertations
A series of spatially based models of Hawaiian streams and stream fish habitats were developed to aid in the conservation of native fishes. The spatial models focused on the quantification of habitat for native fishes at three levels within a spatial hierarchy. First, at the reach level, the models classified the major geomorphological features of a stream and its watershed to determine the distribution of fish habitat within the different sections of the stream. The distribution of habitat was combined with habitat suitability criteria and the migratory abilities of the native fishes to quantify available habitat and predict expected community …
Validation Of Annagnps At The Field And Farm-Scale Using An Integrated Agnps/Gis System, Glenn M. Suir
Validation Of Annagnps At The Field And Farm-Scale Using An Integrated Agnps/Gis System, Glenn M. Suir
LSU Master's Theses
Non-Point Source (NPS) pollution models are effective watershed-scale predictors of NPS loadings and useful evaluators of agricultural Best Management Practices (BMPs) and water quality Total Maximum Daily Loads (TMDLs). The work reported in this thesis examined two applications of the AGricultural Non-Point-Source (AGNPS) pollution model: 1) predicting surface runoff, nutrient loading, and sediment yield predictions for an artificially delineated farm-scale watershed; and 2) evaluating relative benefits of different BMPs on reducing sediment accumulation in a lake surrounded by agricultural land. A procedure using identification, extraction, and processing of critical area data using an ArcView Geographic Information System (GIS) was used …
