An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr Jan 2009

An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr

Dr. Fanan Ujoh

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 …

Management Of Forests Through The Application Of Advanced Technologies, Praveen Jha Dr

Praveen Jha Dr

Several state-of-art geo-spatial programs developed by the author could be applied to generate technological pathways for providing an integrated solution to the loads of problems in the forests in the most scientific, objective and effective manner so that the management prescriptions incorporating policy interventions may prove to be highly successful. Three state-of-art geo-spatial programs - Multi-Algorithm Automation Program (MAAP), Data Automatic Modification Program (DAMP) and Multi-Stage Simulation Program (MUSSIP) – developed to address the pertinent issues of conservation and sustainability could be used extensively. Based on satellite data, MAAP produces land use land cover (lulc) map of the present period, …
