summarized for the years 2004 and 2014 in Table 4.4 From 2004 to 2014, water bodies areas increased 79.47 (0.3%) with quite low percentage Besides that, building areas raised relatively with number 4995.63 (18.39%) On the other hand, vegetation areas decreased 5075.1ha (18.69%) Therefore, we can realized that having a change area between two classification is building and vegetation As seen in Table 4.4, the area well qualified for building area was 9333.36 in 2004, while the building area increased about 18.39% and reached up to 14328.99 in 2014 On the other hand there was a 5075.1 decreased in vegetation areas (decreased from 17110.16 to 12035.06 ha) during the period between 2004 and 2014 The increase in building areas (4995.63 ha) and the decrease in forest areas (5075.1 ha) are approximately the same These given data expressly state that the increase in building areas mostly result in processing built-up urban which means some vegetation areas were removed and converted to the building in the region 51 4.3.2 Land cover Map for Landsat TM (2004) Figure 4.2: The classified images of land cover map for 2004 Figure 4.3 : The statistics percentage of land cover type classification in 2004 52 PART I INTRODUCTION 1.1 Research rationale Land is one of the most important natural resource, serving as a support for life and other developmental activities Nowadays, population increased dramatically released to population density rise and industry zone, the private industry park and raise strength economic society All of things which affected strong to land, specific with a city have speed development quickly such Taipei city Overtime, with these pressures of urbanization speed, which became main reason related to LCC Additionally, land cover impacted under strong natural disasters, human, economic and social development activities Study building the LCC map by satellite image and GIS technology helps to shorten the time compared to other technology mapping ago and it is factor important contributions in the management and assessing the current state of the environment Therefore, the monitoring, research, management and the use of urban environment is an effective and reasonable speed urbanization developing such as Taipei city in Taiwan Remote sensing and GIS technology are well developed and widely applied to the related fields such as: atmosphere, hydrology, geology, environmental and agriculture, forestry observations Therefore, it’s an efficient way to monitor the changes of land cover by means of remote sensing technology with high accuracy for the environmental management of research area Thus, having this project conducted “Application of satellite image and geographic information system (GIS) to build up the land cover change map for the management of Taipei city, Taiwan” Figure 4.5: The statistics percentage of land cover type classification in 2014 Figure 4.4 shows the land cover classification map from the Landsat image of 2014 A close look at the image reveals that there was a significant intrusion of building areas in to the surrounding vegetation and the reduction of the scattered vegetation cover in settlement areas that was present in the 2004 classification image (Figure 4.2) This left the vegetation cover to have made up 44.29 % (12035.06 ha) of the total area, as shown by the histogram in figure 4.5 With continuous growth registered since 2004, the building area was more significant than ever before in 2014, covering up to 52.74 % ( 14328.99 ha) The fraction of water bodies made up about 2.97% (805.95 ha) of total area over Taipei city 54 4.4 Land cover change map from 2004 to 2014 Figure 4.6: Land cover change of Taipei city in 2004-2014 Table 4.5 : Statistical fluctuations of land cover change in the period 2004 - 2014 Changing of Land Cover Type Water Areas( hectares) 663.66 % Total areas 2.44 Water to Vegetation 17.4 0.064 Water to Building 47.97 0.18 Vegetation to Water 110.25 0.4 Vegetation 14109.78 51.93 Vegetation to Building 2883.05 10.61 Building to Water 30.51 0.11 Building to Vegetation 201.81 0.74 Building 9104.04 33.51 55 According to the table 4.5 about statistical fluctuations of land cover change in period 2004-2014 Thefore, we can analysis of land cover change based on "from-to" categories between the 2004 and 2014 images revealed that changing from vegetation to building occupied the highest was 2883.05 (10.61%) , followed by changing from water to building occupied 47.97 (0.18%) and the fewest were changing from water to vegetation occupied 17.4 (0.064%) From results analysis the figure 4.6, the land cover change classified images were visually inspected for changes from 2004 to 2014 The figure clearly showed the land cover classes from vegetation to building that have changed in this study period of about a decades with increase of the building area and decrease of the vegetation classes been very prominent This is highly related to the issue of urbanization speed The post-classification comparison gives a better idea of the changes that occurred within a period of 10 years by visually looking at the images and inspecting the areas where settlements has expanded and deforestation has occurred 4.5 Brightness temperature map (BTM) for Taipei city 2004 and 2014 Through the two image about BTM from 2004 to 2014, it can be seen that the major temperature range from 0C - 35 0C, and it divided six groups and corresponding with each group is other colours For example, in the group highest temperature was 300 C-350C show by red color, the group lowest temperature was 00C -150C show by green color The overall, the high surface brightness temperature (SBT) of more than 27 0C was focused in the metropolitan of the study area, where have building such as industrial, residential and transportation areas were mostly found The areas with 56 surface brightness temperature lower than 250C were traced in the vegetation regions such as river area and cultivable land in the plains The lowest category of less than 150C was seen in the forest highly elevated regions with dense vegetation Figure

aimed at producing land cover maps of the Taipei city in order to monitor LCC with a focus on urban expansion during the period 2004 – 2014 The specific objectives of this study are: - To produce land cover maps for 2004 and 2014 - To detect and analyze the LCC of the Taipei city in the period 2004-2014 - To build-up land surface temperature maps for 2004 and 2014 to assess the environment status 1.3.The requirement - To acquire adequate data of natural condition, socio economic and spatial data - To classify land cover type and process data - To accuracy assesement of land cover map in 2004-2014 - To evaluate the impact of distribution land cover change on transformation of land surface temperature - To be fluent ENVI and Arcgis software to mapping data and analyzing data 1.4 The significance: - For learning and researching purpose: to understand about two software ENVI and Arcgis and to find ways to evaluate the changes in land cover changes and analyze the impact of land cover change to the land surface temperature This study is intended to use remotely sensed data to map and detect changes in land cover of the land cover type in the last 10 years (2004 – 2014) PART V DISCUSSION AND CONCLUSION 5.1 Discussion In order to prevent the impacts of urbanization on land cover changes and surface temperature increase, some methods and policies of environmental management should be proposed Therefore we need to discuss the effective solution such as: + Local government and private sectors should invest in educational and research activities to constantly assess, monitor, and create an up-to-date database on the status of land and natural resources There is need to raise public awareness of the importance and limitedness of land resources This will help facilitate in land related decision-making and improve the management of land resources + Proper and realistic policies and strategies that focused on environmentally benign activities should be put in place and implemented for the sustainable management of land and its resources These policies and strategies need not only conserve the land resources but protect the rights of populace + The human caused stress on the vegetation is reaching its worst point; people and their related socio-economic activities are the major source and cause for land cover change on the study area As a result of these activities, the wild life habitat and biodiversity of the area is affected greatly Parks and nature reserves should be free from permanent human settlements through resettlement programs and other destructive human interferences 59 5.2 Conclusion Based on the analysis and discussion of results in this study, the following conclusions can be summarized This research demonstrates the ability and applications of Remote Sensing and GIS in land-cover change detection Attempt was made to classify as accurate as possible for land cover classes as they change through time with emphasis Three classes of LULC were built-up class as they are a combination of anthropogenic activities which affect other categories Overall, the method of change detection yields acceptable results and the potential for using Remote Sensing Technique in detecting land-cover changes in other parts of the country The results of this study demonstrated that Landsat classification images can be used to produce accurate and reliable change maps, and also can be successfully used to predict the likely trend of the future land cover changes In this research, the overall accuracies of 2004 and 2014 about 94% and 90% with kappa coefficient of 0.90 and 0.85, respectively The usage of satellite imagery is much appreciated, since it has the advantage of not only showing the statistical information for the changes but also visualizing the areas that have or are expected to undergo changes In this study, the conversion of vegetation areas to building is the most significant transformation both in terms of magnitude and with regards to the threat and dangers that it poses to the environment From the results, it can be seen that clear patterns highlighting urbanization activity in the metropolitan area have emerged and increased speed rapidly The results further indicated that the study area (Taipei city) has changed, and the changes mostly 60 affected the urban building and the vegetation areas in terms of the magnitude of land cover area Overall, urban building increased of 18.39 % (4995.63 ha), and most increase of the pixels of this was created from the vegetation land cover categories during the period of the study Therefore, the vegetation land cover categories decrease of 18.69% (5075.1ha) 61 REFERENCES Bikash, B., & Anthony, V.(2015) Tracking Land Use/Land Cover
