by Roshaan HYDRO1k provides a suite of 'FREE' geo-referenced data sets, both raster and vector, which will be of value for all users who need to organize, evaluate, or process hydrologic information on a continental scale.
HYDRO1k is a geographic database developed to provide comprehensive and consistent global coverage of topographically derived data sets, including streams, drainage basins and ancillary layers derived from the USGS' 30 arc-second digital elevation model of the world.
The HYDRO1k data sets are being developed on a continent by continent basis, for all landmasses of the globe with the exception of Antarctica and Greenland. The HYDRO1k package provides, for each continent, a suite of six raster and two vector data sets. These data sets cover many of the common derivative products used in hydrologic analysis. The raster data sets are the hydrologically correct DEM, derived flow directions, flow accumulations, slope, aspect, and a compound topographic (wetness) index. The derived streamlines and basins are distributed as vector data sets.
Datasets are available for Free direct downloads as: Africa Asia Australasia Europe North America South America
And Categorized as: Aspect Compound Topographic Index Drainage Basins Elevation Data Flow Accumulation Flow Direction Slope Streams

by Roshaan Public Data Sets on AWS provides a centralized repository of public data sets that can be seamlessly integrated into AWS cloud-based applications. AWS is hosting the public data sets at no charge for the community, and like all AWS services, users pay only for the compute and storage they use for their own applications.
Previously, large data sets such as the mapping of the Human Genome and the US Census data required hours or days to locate, download, customize, and analyze. Now, anyone can access these data sets from their Amazon Elastic Compute Cloud (Amazon EC2) instances and start computing on the data within minutes. Users can also leverage the entire AWS ecosystem and easily collaborate with other AWS users. For example, users can produce or use prebuilt server images with tools and applications to analyze the data sets. Users can also discuss best practices and solutions in the dedicated Public Data Sets forum.
By hosting this important and useful data with cost-efficient services such as Amazon EC2, AWS hopes to provide researchers across a variety of disciplines and industries with tools to enable more innovation, more quickly.
Available Public Data Sets on AWS
AWS will continue to add to the available collection of public domain and non-proprietary data sets over time. The data sets currently available are shown below. The Linux/UNIX snapshots are in ISO9660 or EXT3 format and the Windows snapshots are in NTFS format.
Here are some examples of popular Public Data Sets: Various US Census Databases from The US Census Bureau
United States demographic data from the 1980, 1990, and 2000 US Censuses, summary information about Business and Industry, and 2003-2006 Economic Household Profile Data.

by Roshaan The primary purpose of this Committee is to examine measures that concerned national, regional and international organizations can take to foster the development of Global Mapping in order to facilitate the implementation of global agreements and conventions for environmental protection as well as the mitigation of natural disasters and to encourage economic growth within the context of sustainable development.
Global Map is a group of global geographic data sets of known and verified quality, with consistent specifications which is open to the public as FREE downloads. Global Map is considered a common asset of mankind, and will be distributed worldwide.
The ISCGM Global Mapping Project supports development of global scale geographic information through international cooperation. Registration is required before data downloading. Global map thematic data sets will provide coverage of the whole land area on earth at 1 km resolution in a consistent manner. Each thematic data set is released to the public in a digital format for easy handling by computer and its content is equivalent to conventional maps at scales of 1 : 1,000,000.
Below map shows the progress & participants of the project. Summary of the Global Map DataThe Global Map Data have 8 thematic layers. They are Boundaries, Transportation, Drainage, Population Centers, Elevation, Vegetation, Land use and Land cover. These layers were produced in either vector or raster data. The layers in vector representation are Boundaries, Transportation, Drainage and Population Centers. The layers in raster representation are Elevation, Vegetation, Land use and Land cover. Vector data and raster data will be downloaded separately. And, raster data can be downloaded separately by every layer.
Sample Map: This map was produced using elevation data and representing the image in 3D
The data source of Land use, Land cover and Vegetation layers is Global Land Cover Characterization datasets by the U.S. Geological Survey's (USGS) Earth Resources Observation System (EROS) Data Center, the University of Nebraska-Lincoln (UNL) and the Joint Research Center of the European Commission. The source of Elevation layers is GTOPO30 by U.S. Geological Survey's EROS Data Center.

by Roshaan The World Database on Protected Areas (WDPA) is the most comprehensive global spatial dataset on marine and terrestrial protected areas available.
Protected areas are internationally recognised as major tools in conserving species and ecosystems. Up to date information on protected areas is essential to enable a wide range of conservation and development activities.
Since 1981 UNEP-WCMC, through its Protected Areas Programme, has been compiling this information and making it available to the global community. The WDPA is a joint project of UNEP and IUCN, produced by UNEP-WCMC and the IUCN World Commission on Protected Areas working with governments and collaborating NGOs.
The World Database on Protected Areas is a foundation dataset for conservation decision making. It contains crucial information from national governments, non-governmental organizations, academic institutions, international biodiversity convention secretariats and many others. It is used for ecological gap analysis, environmental impact analysis and is increasingly used for private sector decision-making.

by Roshaan In a single electronic platform, the World Health Organization's (WHO) Communicable Disease Global Atlas is bringing together for analysis and comparison standardized data and statistics for infectious diseases at country, regional, and global levels. The analysis and interpretation of data are further supported through information on demography, socioeconomic conditions, and environmental factors. In so doing, the Atlas specifically acknowledges the broad range of determinants that influence patterns of infectious disease transmission.
Over the next year, the system aims to provide a single point of access to data, reports and documents on the major diseases of poverty including malaria, HIV/AIDS, tuberculosis, the diseases on their way towards eradication and elimination (such as guinea worm, leprosy, lymphatic filariasis) and epidemic prone and emerging infections for example meningitis, cholera, yellow fever and anti-infective drug resistance.
The database will be updated on an ongoing basis and in addition to epidemiological information, the system aims to provide information on essential support services such as the network of communicable diseases collaborating centres, the activities of the Global Outbreak Alert and Response Network among others.
How to use the Global Health Atlas :

We present these data in an interactive map-based format that allows the user to create individualized maps by selecting data sets and map areas.
The MRP invites participation from other federal, state, and local governmental agencies in supplying data to this web site. Because there have been questions in the past concerning ownership and publication rights to digital data sets, the MRP issues this policy statement, which covers all data presented on this web site. What users gets:
- Display all data sets on screen at scales that are appropriate to the data set.
Overlay data sets in any combination. Print simplified explanations (symbols and short descriptions) for all data sets. Print small-scale (page-sized) renditions of maps containing any combination of data sets. Download plot files to plot maps containing any combination of data sets at user-specified scales. Query all data sets. Download portions of data sets that are freely available to the public.
Future Enhancements
The development and enhancement of the SIDP ArcIMS client is active and ongoing. Currently, the client, which is written primarily in JavaScript, is undergoing additional customization to provide added functionality. In the future additional spatial data sets will be included as they become available.
