Obafemi Awolowo University (OAU) is located in Ife Central, Local Government Area (LGA), Osun State, Nigeria. Car parks adequacy and their mode of utilization is a challenge to the University community, hence the use of geospatial techniques to analyse car parks adequacy in OAU campus academic areas. Google earth image covering the study area was captured, the Geographic Positioning System (GPS) points of the existing parks was taken, the capacities of the park were noted and the inflow and outflow of cars from existing car parks for a period of one Month, within the study area was also taken. The image was georeferenced, mosaicked, and after this, the following features were vectorized; roads, buildings and the car parks and this information were stored in the geodatabase. These data was now incorporated with existing literature for geospatial analysis. Result indicates that the University has twenty nine car parks in the academic area. Almost all the car parks were over utilized while few were under-utilized. It was also noted that some areas where people parked their cars were not designated by the University authority as car parks. None of the parks has space for motorcycle, bicycle, or designated place for people with physical challenges. Larger car parks with provision for all and sundry should be put in place and underground car parks should be considered for future or ongoing structure while enforcing the university rules with respect to car parks.

The United States government spends millions of dollars on construction every year. Each construction project paid for by the government is subject to the requirements of the Davis-Bacon Act (DBA). The DBA is a federal law that sets minimum wages, called prevailing wages, for construction workers. This research used the geographic information system ArcGISTM to compare wages based on DBA requirements to wages earned by construction workers on non-federal projects not subject to DBA requirements. The research studied wages of eight different construction trades at all active military installations in the United States and compared the two wages to determine if there was a significant difference, and if so, what it was. It also determined the existence of any spatial relationships between the wage differences. The research also applied its findings to the U.S. Air Force's construction budget for Fiscal Year 2012 to determine the amount spend based on DBA requirements. The research found that DBA wages are statistically higher for seven of the eight trades, which differs based on the trade, and confirmed the existence of several spatial relationships. The research concluded that the Air Force spent over $60 million in Fiscal Year 2012 based solely on DBA requirements.

GIS is a collection of tools and techniques that works on the geospatial data and is used in the analysis and decision making. Education is an inherent part of any civil society. Proper educational facilities generate the high quality human resource for any nation. Therefore, government needs an efficient system that can help in analysing the current state of education and its progress. Government also needs a system that can support in decision making and policy framing. GIS can serve the mentioned requirements not only for government but also for the general public. In order to meet the standards of human development, it is necessary for the government and decision makers to have a close watch on the existing education policy and its implementation condition. School mapping plays an important role in this aspect. School mapping consists of building the geospatial database of schools that supports in the infrastructure development, policy analysis and decision making. The present research work is an attempt for supporting Right to Education (RTE) and Sarv Sikha Abhiyaan (SSA) programmes run by Government of India through the use of GIS. School mapping of the study area is performed which is followed by the geospatial analysis. This research work will help in assessing the present status of educational infrastructure in Jasra block of Allahabad district, India.

International audience ; Research area: Taipei urban landscapes, Taiwan. Located on the north of the Taiwan Island, Taipei is the country's core urban political and economic center with population reaching over 2.6 M and continuing to expand within the city.Research aim: spatio-temporal analysis of urban dynamics in study area during 15 years (1990-2005).Research objective: application of geoinformatic tools, remote sensing data and application of methodology to spatial analysis for a case study of Taipei.Data capture: The data include Landsat TM images taken from the U.S.G.S. website. The software used is ENVI GIS.Research problem: In the past decades, the process of urbanization has become more notable in the East Asia. Since past decades, Taipei city undergone serious urban changes.The development of urban landscapes in Taipei has unique feature; Taiwan's exceptional economic and industrial growth since 1980s, which is often referred as "industrial wonder of Taiwan".Results: In this research the analysis of changes in landscapes has been done using tools of geospatial analysis. Namely, two satellite images Landsat TM have been processed and classified using ENVI GIS software. As a result of classification, the areas occupied by different landscape types have been calculated and analyzed. Moreover, it has been detected that different parts of the city of Taipei were developing with different rate and intensity. Three (3) different residential types of the city were recognized and mapped. The results demonstrated following outcomes: 1) intensive urban development of the city of Taipei; 2) decline of green areas and natural spaces and, on the contrary, increase in anthropogenic urban spaces; 3) not parallel urban development in different districts of the city of Taipei during the 15-year period of 1990-2005. Discussion: Recently, the country quickly transformed from an agriculture-based traditional economy into a highly industrialized society. As a result, Taiwan has now a new face of high-technology oriented, ...

International audience ; Current poster presents an example of Landsat TM image processing using ENVI GIS. Research area: Taipei, Taiwan. Located on the north of the island, Taipei is Taiwan's core urban, political and economic center; population >2.6 M continuing to expand affecting urban landscapes. Research aim: spatio- temporal analysis of urban dynamics in study area during 15 years (1990- 2005) Research objective: application of GIS methodology and remote sens- ing data to spatial analysis for a case study of Taipei. Data: Landsat TM images taken from the USGS. Software: ENVI GIS. Workflow includes following steps: 1) Preliminary processing 2) Creation color composites 3) Classification using K-means algorithm 4) Mapping using classification results 5) Accuracy assessment. The preliminary data processing includes image contrast stretching, which is useful as by default, ENVI displays images with a 2\% linear contrast stretch. For better contrast the histogram equalization contrast stretch was applied to the image in order to enhance the visual quality. The analysis of landscape changes was performed by geospatial analysis. 2 satellite images Landsat TM were processed and classified using ENVI GIS. Result of classification: areas occupied by different land cover types were calculated and analyzed. It has been detected that different parts of the city of Taipei were developing with different rate and intensity. 3 different residential types of the city were recognized and mapped. The results demonstrated following outcomes: 1) intensive urban development of the city of Taipei; 2) decline of green areas and natural spaces and, on the contrary, increase in anthropogenic urban spaces; 3) not parallel urban development in different districts of the city of Taipei during the 15-year period of 1990-2005.

AbstractA geographical concentration of businesses enables them to mitigate the drawbacks arising from their small size. It is therefore important to highlight the existence of such zones and their location in regions where most businesses are SMEs, such as the Valencia Community region. Moreover, it is particularly important for technological companies, since such concentrations act as a means of increasing their productivity. By using georeferencing software, SatScan, four zones with a high concentration of technological companies are identified superimposed on zones with a very industrial tradition. The profile of the companies analysed could be of interest in implementing suitable industrial policies.
