Habitat Type Mapping In Montana De Oro State Park Through Gis Image Classification, Evan Corrales, Sarah Fockler Jun 2013

Habitat Type Mapping In Montana De Oro State Park Through Gis Image Classification, Evan Corrales, Sarah Fockler

Natural Resources Management and Environmental Sciences

This project involved using aerial imagery and GIS procedures to automatically map the basic vegetation communities present within Montana de Oro State Park, CA: grassland, coastal scrub, bare ground, woodland, and riparian areas. 1m resolution color imagery of the park from the NAIP 2005 (National Agriculture Inventory Program) and 1m resolution LiDAR height data were also used to determine the locations of the different vegetation types in the park. This data was then classified by color using the interactive supervised classification tool in ArcGIS. Points were taken in the park using a GPS unit, and compared with the GIS results …

Keeping It Wild: Mapping Wilderness Character In The United States, Steve Carver, James Tricker, Peter Landres Jan 2013

Keeping It Wild: Mapping Wilderness Character In The United States, Steve Carver, James Tricker, Peter Landres

USDA Forest Service / UNL Faculty Publications

A GIS-based approach is developed to identify the state of wilderness character in US wilderness areas using Death Valley National Park (DEVA) as a case study. A set of indicators and measures are identified by DEVA staff and used as the basis for developing a flexible and broadly applicable framework to map wilderness character using data inputs selected by park staff. Spatial data and GIS methods are used to map the condition of four qualities of wilderness character: natural, untrammelled, undeveloped, and solitude or primitive and unconfined recreation. These four qualities are derived from the US 1964 Wilderness Act and …


Land Suitability Assessment For Rice Cultivation Based On Gis Modeling, Orhan Dengi̇z Jan 2013

Land Suitability Assessment For Rice Cultivation Based On Gis Modeling, Orhan Dengi̇z

Turkish Journal of Agriculture and Forestry

The main objective of this study was to develop a spatial model for land suitability assessment for rice (Oryza sativa L.) cultivation using geographic information system (GIS) techniques. The land mapping units, resulting from the overlay of the selected theme layers, have unique land quality information, on which land suitability is based. Results showed that 55.5% of the study area is highly or moderately suitable for rice cultivation, whereas 34% of that area is unsuitable for rice cultivation due to soil and topographic conditions. The model was also validated with field studies. According to the statistical analysis, there was a …
