In developing countries, the lack of infrastructure like GPS (Global positioning system)and GIS (Geographic Information system) have hindered the growth of the police department. This paper proposes a simple, useful and cost effective solution for crime mapping. Google cloud resources like satellite data, application and GIS software have been used to develop this application. The developer requires only a simple computer connected to the internet. The source of crime data is the RSS (Really Simple Syndication) feeds from various news websites.
The potential for on-shore wind energy deployment in India is considerably higher than the official estimates— around 20 times and up to 30 times greater than the present government estimate of 102 gigawatts, according to a new study led by an Indian origin scientist.
This landmark finding by Lawrence Berkeley National Laboratory may have significant impact on India’s renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity.
The Berkeley Lab study undertook a systematic assessment of the availability of land using publicly available GIS (geographic information system) data on topography and land use and found a significantly higher availability of land that can potentially be used for wind power development, which is the primary reason for the higher potential estimates.
The study excluded land with low-quality wind, slopes greater than 20 degrees, elevation greater than 1,500 meters and certain other unsuitable areas such as forests, bodies of water and cities.
The researchers obtained off-the-shelf wind speed data for heights of 80 meters, 100 meters and 120 meters from 3TIER.
International development requires an integrated approach to address complex challenges experienced within sectors such as agriculture, environment, health, education, economic growth, democracy and governance, and disaster response.
This is where the use of GIS comes in.
Using GIS allows organisations to go beyond making maps of just land cover. It enables them to combine layers of information, and study the spatial relationship between selected indicators to get a more holistic view of places or regions they are working to develop.
At present, these organisations are using GIS in missions to collect data about the in-country projects they fund across all sectors. The resulting mission portfolio databases are most often used to generate maps of their projects to visualise their respective location, track progress, and communicate what is going on and where. This is quite similar to how an organisation such as the World Food Program (WFP) uses its GIS during its disaster response and recovery operations.
According to Syed Fawad Raza, Program Officer and Spatial Analyst at the World Food Program in Pakistan, the agency leverages GIS for food security analysis to target which areas are hotspots and food-deprived. Based on its research and through studying the spatial relationships of variables involved, it is then able to plan intervention in affected areas.
“GIS plays a very crucial role in supporting WFP’s mandate in helping communities cope with the effects of calamities or disasters, and also in helping those affected communities stand up again and rebuild their lives. That’s how our cycle works and of course mapping is central to monitoring and evaluation, identifying areas, gaps, crucial hot spots, and where to go,” he said.
In other cases, GIS is being used as a component of a larger program to address a specific development challenge.
In Uganda for example, the United States Agency for International Development (USAID) involved local villagers in participatory mapping as part of a biodiversity conservation project to reduce human-wildlife conflicts. The maps produced by the community were compared to the district government’s land use boundaries, and helped resolve the conflict about rights to land resources.
At a regional level, the Central African Regional Program for the Environment uses satellite imagery to map forests and monitor changes due to logging. Information derived is then shared with the governments of nine countries spanning the catchment basic of the Congo river.
At a Global level, USAID supports a global program called the President’s Emergency Plan for AIDS Relief (PEPFAR), which aims to establish a repository that would then provide geographically-linked HIV-related data for mapping in a GIS. In addition, USAID is also collaborating with NASA in a program called SERVIR (which means “to serve” in Spanish), which aims to build the capacity of countries in the Mesoamerican, East African, and the Hindu-kush Himalayan regions to use remote sensing, mapping tools, and geo-visualisation to address climate change and other environmental issues.
More than a decade ago, world leaders gathered together at the United Nations Millennium Summit to pledge the achievement of eight development goals by 2015.
Scientists from the University of Maryland and Beijing Normal University are partnering to track and predict the impact of climate change internationally.
When fully developed, the project will provide monitoring and predictive tools that can help, for example, predict crop failure and changes in commodity prices, and aid in preparations for shortages, organizers say.
At the University of Maryland today, officials from both institutions and representatives from the Chinese government officially launched the new Joint Center on Global Change and Earth System Science, which will conduct the research.
Creation of an international remote sensing database will be one of the new center’s first projects, and the interdisciplinary work will take place in both countries. In addition to monitoring agriculture, it will also track land use and land cover.
When coupled with predictive modeling techniques, the remote sensing database can produce a range of useful tools to assist in planning for climate changes, the project organizers emphasize.
“International cooperation is the path forward on global-scale challenges such as climate change,” says University of Maryland President Wallace Loh, who secured support for the new center when he visited China last year with Governor Martin O’Malley.
“The combination of our joint expertise and resources in this new center will allow us to address these important challenges with much greater sophistication and impact,” Loh adds. “These scientists have worked together for years now, and this new collaboration represents the maturing of that relationship. I’m confident their work will benefit our state, both nations and the international community.”
The new center directly results from Loh’s visit to China last year when he met with top government figures in science and academia.
At Beijing Normal, the center’s research will be coordinated by the College of Global Change and Earth System Science.
