Creation Of Soil Liquefaction Susceptibility Maps For San Luis Obispo & Marin Counties Using Geographic Information Systems., Amelia M. Lowman
Creation Of Soil Liquefaction Susceptibility Maps For San Luis Obispo & Marin Counties Using Geographic Information Systems., Amelia M. Lowman
Earth and Soil Sciences
Liquefaction of soils in response to earthquake shaking is a pressing issue in the state of California. Using Geographic Information Systems, Geological and lithology layers, along with criteria in order to separate out the data into four risk categories, a liquefaction risk assessment map was created for San Luis Obispo and Marin Counties. The accuracy of these maps was then assessed using liquefaction occurrences for San Luis Obispo County, and it was determined that while the map is somewhat accurate, in order to obtain a greater amount of accuracy and increase the usefulness of these maps, more data would need …
Lower Tropospheric Temperature Variability Over The Usa: A Gis Approach, Souleymane Fall, Dev Niyogi, Gilbert L. Rochon
Lower Tropospheric Temperature Variability Over The Usa: A Gis Approach, Souleymane Fall, Dev Niyogi, Gilbert L. Rochon
GIS Day
We use the high resolution North American Regional Analysis (NARR) dataset to build for the United States a Temperature Change Index (TCI) based on four contributing variables derived from the layer-averaged temperature and lapse rate of the 1000mb - 700mb layer (near-surface to 3000 meters) for the 1979-2008 period. The analysis uses Geographic Information Systems (GIS) methods to identify distinct regional patterns based on aggregate temperature trends and variability scores. The resulting index allows us to identify and compare regions that experience high (low) temperature trends and variability that are referred to as hot spots (cold spots). The upper Midwest …

Urbanization is a process that always initiates the continual transformation of land from one use to the other. Land transformation is presently being experienced in and around fast growing towns, like Anyigba in Kogi State. This study used Remote sensing and GIS techniques to identify, mark, and measure the extent of the various land uses from the Land use map of 1995 and Nigeriasat 1 imagery of 2006. The study revealed that there have been tremendous transformation in the various land uses, with the built-up area expanding more than other land uses with 398.4%. Gaining 167 ha, 613.45 ha, 159.62 …
An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Olarewaju Oluseyi Ifatimehin
An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Olarewaju Oluseyi Ifatimehin
Olarewaju Oluseyi Ifatimehin
This research integrated remote sensing and Geographic Information Systems (GIS) to identified land use/cover types in Lokoja, including their temporal transformation and association with surface temperatures from the LandSat TM and LandSat ETM imageries of 1987 and 2001 respectively. As the built-up area increased in size (2667.6%) so was the surface temperature (6.48oC), vacant land (872%: 9.65oC), cultivated land (104.4%: 1.2oC) and water bodies (64.3%:0.94oC) while vegetation cover increased by 2.44oC while its area extent decreased (316.7%). These changes were responsible for the rise in the mean surface temperature from 38.39oC in 1987 to 42.61oC in 2001, indicating a 4.22oC …
Solid Waste Management Through The Application Of Advanced Technologies, Praveen Jha Dr
Solid Waste Management Through The Application Of Advanced Technologies, Praveen Jha Dr
Praveen Jha Dr
State-of-art long term plan for Solid Waste Management (SWM) including collection, transportation and disposal of Solid Waste (SW), as well as for monitoring of SWM, by generating integrated solution could be generated through the application of advanced technologies so that the policy interventions may prove to be highly successful and cost-effective. Currently, SWM plans are either non-existent or are riddled with serious problems and limitations. SWM plans are extremely expensive. Long term planning could be done for collection, transportation and disposal of SW in such a manner that Waste Collection Points, transportation routes, schedules regarding transportation, loading, unloading, stoppage etc, …
Application Of Remote Sensing And Gis Techniques In Mapping Fadama Farming Areas, Olarewaju Oluseyi Ifatimehin, Sunday Ishaya
Application Of Remote Sensing And Gis Techniques In Mapping Fadama Farming Areas, Olarewaju Oluseyi Ifatimehin, Sunday Ishaya
Olarewaju Oluseyi Ifatimehin
The importance and scarcity of fadama land as well as the needs for their sustainable development and management, mapping of potentials areas is likely to be the reliable step towards effective and efficient way in securing the food needs of the populace and as well as developing the rural areas in Nigeria. This study used Remote Sensing and GIS techniques to identify potential land use areas for fadama farming and then produce map. Four steps were followed in mapping these areas: (i) topographic map of the study area was scanned and imported into the ILWIS GIS software, which was then …
