The rapid development of advanced geospatial technologies, such as satellite imagery, aerial photography, Global Navigation Satellite Systems, Global Positioning System (GPS), laptop computers and geographic information system, has opened up unprecedented opportunities for the use of geo-graphic information. The impact of these events on the official statistics were most felt at all stages of the census and housing, where the use of geo-information tool commentary has significantly improved performance on the stage of the census and the stage of pilot test results. These tools are also increasingly used in context of disaster management, environmental monitoring, protection of natural GOVERNMENTAL resources, land use, provision of utilities, etc.
The reason for this being they contribute to the rapid collection of data and facilitate in-depth analysis of the data, and also allow for a flexible and integrated under-approach to the exchange and dissemination of information based on geospatial model.
It is becoming increasingly clear that the applications of these technologies and subsequent management of geographic information are strategic value.
This creates two problems:
- How to more effectively manage geographic information at all levels (national, regional and global).
- How to solve the problems of interaction and integration of geo-classical and statistical information.
This outlines talk about problems with the proliferation of geographic data and their integration into social, economic and other data in the field of development disabilities in the SRI technical standards, lack of legal basis for the management of geospatial information and, in particular, the lack of global co-ordination. It particularly focuses on the specific issue of integration statistical and geographic data and shows that the statistical systems benefit from the integration of geographic information systems in order to build the geospatial infrastructure support the census and other statistical activities.
In conclusion of the report, it contains some recommendations which Statistical Commission may wish to endorse as to strengthen national geographic information systems, and for promoting more integration of geographic and statistical information.
Management of Geographic Information
Application of geospatial technologies to a large extent increased the amount collected and stored geospatial data. In the present time we have access to the images, for which in the past, cost was incredibly expensive and required experts with specialized training. Within just a few decades the number of people who use geographic data, increased exponentially throughout the world, and the influence can be traced easily and widely reflection It was found in the popular press by many experts. Volumes of data increases sharply with the integration of descriptive data (demographic, co-social, economic, environmental, etc.) with maps and geographic data (geographical features). Traditional function of a distribution map supports the use of modern forms. In many ways, mapping services have become a new channel of geo-communication with hundreds of millions of users, post on-consumes and compares the data on the principles of collective action through the Web applications, and other map services.
In circumstances where the creation of new businesses was driven by new advances in information and communication technologies to community dealing in geospatial mapping, stand some very important issues: how can they harness the enormous potential of geospatial technology and, going beyond the local and national scope, go to the kinds of regional and global scale and how to ensure a comprehensive management of geospatial data sets, using the Internet and multimedia tools to disseminate information, which require to make vital decisions in support of social, economically and environmentally sustainable development.
From a national point of view of new conditions that characterize the economic competition and increased demand for geo-information products, greatly affected the traditional monopolies created for provision of public goods, pushing them to improve efficiency on the supply of geospatial data and access to them. This explained the need for many active players in the field of geographic information, including national mapping offices, islands, to reconsider their position in the community of those engaged in pro-geospatial data to ensure effective control on country level. To improve governance and bring economic benefit to the country, requires general framework for geospatial data – infra-geospatial data – which combines data, metadata, services, users and tools, which are interconnected to ensure an efficient and flexible use of space data for many applications.
ESDS has taken significant steps to develop a comprehensive geospatial data infrastructure. The aim of this initiative is to ensure more easily accessible geospatial data for developed country throughout the Indian Community.
Integration Of Statistical And Geographical Information
Statistical data, including many of the data in the field of development about the economy and public health concern, which can be defined geographically. It is increasingly recognized as a key to practical national statistics, providing a framework for the collection, formation of processing, storage and data fusion. Integration of geographic information and statistical programs bring considerable benefits to national statistical offices, since it reduces the cost and time, friction for the collection, compilation and dissemination of information and leads to increase the number of services and much greater use of statistical information that greatly increases the return on investments resources in data collection.
Mapping is one of the most important activities. The accuracy of differentiation of areas of and quality of their images is a most serious concern for quality of data collected. Increasing use of portable devices with GPS receive low-cost images from the air and from satellites, the collection of geospatial data and the demarcation of areas of statistical surveys, and geographic information systems for displaying information dramatically improved mapping. Multiple providers and users currently easily collect and disseminate geographic data access and use them. Through geographic information systems may turn out to call the support of all three main stages of the operational activities of any national statistical office: the integration of field data, the processing of statistical data and distribution data and supporting statistical surveys with the use of using the card, which can be provided via a wide public access.
Rapid integration of geospatial data from a variety of other data, including demographic and social-economic data and their analysis and simulation have increased the level of understanding of the dynamics of social, economic and demographic structures and helped get more accurate data, timely and objective information to better process the decision making. For example, this integration was exceptional relatively important to ensure higher operational readiness and the act to respond to natural disasters. Using satellite images, scientists and demographers can compare the images and statistics after the earthquake to assess the amount of aid that should be allocated.
Institutional arrangements vary widely in different countries. In many cases, the collection of statistical data and collection of GOVERNMENTAL geospatial data, include the creation of thematic maps made by different organizations. This often leads to a lack of common standards and as a result of non-interoperability of data and the emergence of other quality-related problems, such as incomplete documentation of data. However, the close relationship between geography and statistics exist in those countries where national statistical and cartographic departments organizationally integrated.
Regardless of the institutional arrangements of the country are increasingly power-penalties are finding that they can use the strengths of the national statistical and mapping agencies through so-called national geospatial data infrastructure.
Organizational mechanism to share data and collaborate on all government agencies at various levels, including national LIMITED, regional and local. For example, the basic data sets such as Demography and administrative boundaries, which are generated by national statistical offices can be shared between other users, thus eliminating the costs associated with concurrency in work. These arrays are important components of any national geospatial data infrastructure.
However, in many developing countries, the infrastructure for pro-geospatial data is still at a very early stage of development. There is also no national strategy at various levels in the ratio.
In this regard, it is essential to raise awareness in between political leaders and those who shape policy, the utility and the types of application of geospatial data together with statistical data. In this on-wearing the Statistics Division should continue to promote partnerships between national statistical with acoustic offices and national mapping agencies and promote the concept of national infrastructure space governmental data and its critical role as a foundation for regional and global geospatial data infrastructure.
National Geospatial Data Infrastructure
National Geospatial Data Infrastructure is a combination of technology, policies, standards and human resources required for the acquisition, processing, storage, distribution and better use of geospatial data infrastructure of government. Despite this, the user still don’t know what are the sets of geospatial data, that have their special characteristics, and don’t know how they can be accessed. In other words, government organizations geospatial data and information are available in large volumes, But even those who make decisions in the public sector, it is difficult to access them.
The foundation for a geospatial data infrastructure is established to:
a) Facilitate the organization of production, storage, dissemination and utilization of geospatial data access and sharing these data coming from government organizations at all levels for development of the country;
b) Promote the use in generating geospatial experimental data by government organizations at all levels of standards and specifications approved by the Commission for Cartography;
c) Avoid duplication and wastefulness in the use of resources on the acquisition of geospatial data governmental organizations through the issuance of the relevant metadata of these same organizations.
In accordance with the legal framework, all federal organizations, that produce and maintain geospatial data and information, necessarily provide their congregation, including the appropriate metadata for public use through the geospatial data services. Directory has been defined as a system of servers, ditch your data online, which aims to unite manufacturers, administrators, operators and users of geospatial data in cyberspace for the purpose of facilitating the storage of geospatial data and information sharing and access, as well as providing appropriate services.
The decree also states that any user is properly identified through the so-called portal of geospatial governmental data, who have the opportunity of free access to all digital geospatial information provided by the Directorate geospatial governmental data.
Integration of statistics in national infrastructure geospatial data opens up new horizons, taking into account the possibility correlate these data with all other data sets, such as GOVERNMENTAL data, relating to natural resources and environment. New sources are available through the network technologies that enable the national statistical offices to produce a fully digital mapping, bringing together maps, nformation on the areas, image, and text files, and file addresses.
New Ways To Disseminate Data
The Government is using two permanent systems to monitor deforestation in the region, Data on deforestation can be combined with forests and vegetation survey using geoinformation systems in order to give an indirect assessment of the volume of timber extracted from the forest in a particular area or at a particular time.
Increasing recognition that the geography and statistics related to the geospatial distribution of social, economic and environmental indicators serves as a guide for strategic decision-making areas such as regional development, service delivery and planning for resources.
Many other countries have established a sound basis for the use of graphic data based on the symbiotic Dense tropical forest, lowland, the foothills, and areas of human activity.
This indicates the need for better national recognition of the cooperation between the geographical and statistical sectors as strategic areas for development.
Emphasizing the fact that these new geospatial technologies require strong government policies and the mobilization of considerable resources at national levels, as well as coordinated mobilization at the regional and global levels, which goes beyond traditional cartographic activity and provides a flexible and integrated approach to global, regional and national geospatial and statistical information infrastructure and propose mechanisms for more effective and sustained coordination between all.
By taking this into consideration, the Statistical Commission would have professional support by findings professional experts on GIS issues.
