The final goal of this paper was to fix a brief summary on the status of geographic information in Italy due to the technological steps and national regulations. The acquisition, processing and sharing of spatial data has experienced a significant acceleration thanks to the development of computer technology and the acknowledgment of the need for standardization and homogenization of information held by pub­lic authorities and individuals. The spatial data represents the essential knowledge in the management and development of a territory both in terms of planning for safety and environmental prevention. In Italy there is an enormous heritage of spatial information which is historically affected by a problem of consistency and uniformity, in order to make it often contradictory in its use by the public decision-maker and private par­ties. The recent history of geographic information is characterized by a significant effort aimed at optimiz­ing this decisive technical and cultural heritage allowing the use of it to all citizens in a logic of sharing and re-use and may finally represent a common good available to all.

The increasing need for property in Tanjungpinang City is very growing, especially in the housing sector. Selection of property based on location and facilities and infrastructure is always a consideration for the community in making decisions to buy a property. Difficulty finding property location information in a certain area often occurs, resulting in people not getting references about the properties offered in Tanjungpinang City. The purpose of this research is to create a web-based geographic information system (GIS) regarding the distribution of the number of properties on offer, especially in Tanjungpinang City using a web-based mapping approach. In the development of Property GIS the author uses the Waterfall method and in the analysis of system requirements it is modeled with UML (Unified Modeling Language) and implemented with the PHP programming language and MySQLI database. It is hoped that the results of making this property's geographic information system can help the public to find out information about the distribution of properties offered, such as the location of property coordinates, addresses, prices, property photos, property specification data and property developer data.

<p><strong>Abstract.</strong> National geographic conditions monitoring and basic surveying and mapping are two important tasks of the surveying and mapping department, and they are similar in production organization and technology realization. In the process of operation, both of them need to carry out internal collection, base map production, field verification and so on. It is operationally feasible to carry out cooperative production of national geographic conditions monitoring and basic surveying and mapping. From the perspective of technical process and method, both of them are carried out by combination internal and field work. Firstly, based on remote sensing images and thematic geographic data, the internal work will perform image interpretation and obtain staged results data. Then, the field verification will be carried out to make judgments and adjustments. Finally, the results of the field verification will be transferred back to the internal work, and the data will be further edited and organized in the internal work to obtain the final data.</p><p>Basic surveying and mapping focuses on abstract representation of the real world, but lacks comprehensive integration of information and in-depth knowledge mining. National geographic condition monitoring focuses on the spatial distribution, characteristics and interrelations of natural and human geographical elements on the surface. There are many differences between basic surveying and mapping and national geographic conditions monitoring in the content and index of data collection, data stratification and element attribute. But basic surveying and mapping results are the basic data for national geographic conditions monitoring and national geographic conditions monitoring data is an important update data source for basic surveying and mapping.</p><p>On the one hand, part of the geographic information can be updated on the basis of extracting relevant basic geographic information element data and attribute information, On the other hand, timely basic geographic information data can be used as the direct basis for the collection of geographic information.</p><p>This paper designs the technical methods and workflow of the cooperative update mechanism based on the relevant technical documents of national geographic conditions monitoring and basic surveying and mapping. It will enable one-time acquisition of data needed for the national geographic conditions monitoring and basic surveying and mapping, "one-time collection, classification and utilization". It will save a lot of time and effort, reduce workload and improve productivity.</p>

TIANDITU (Map World) is the public version of the National Platform for Common Geospatial Information Service, and the travelling channel is TIANDITU-based geographic information platform for travelling service. With the development of tourism, traditional ways for providing travelling information cannot meet the needs of travelers. As such, the travelling channel of TIANDITU focuses on providing travel information abundantly and precisely, which integrated the geographic information data of TIANDITU Version 2.0 and the authoritative information resources from China National Tourism Administration. Furthermore, spatial positioning, category and information query of various travelling information were offered for the public in the travelling channel. This research mainly involves three important parts: the system design, key technologies of the system design and application examples. Firstly, this paper introduced the design of TIANDITU-based geographic information system for travelling service, and the general and database design were described in detail. The designs for general, database and travelling service above should consider lots of factors which illustrated in the paper in order to guarantee the efficient service. The process of system construction, the content of geographic information for travelling and system functions of geographic information for travelling are also proposed via diagram in this part. Then several key technologies were discussed, including the travelling information integration for main node and among nodes, general architecture design and management system for travelling channel, web portals and system interface. From the perspective of main technologies, this part describes how TIANDITU travelling channel can realize various functions and reach the requirements from different users. Finally, three application examples about travelling information query were listed shortly. The functions and search results are shown clearly in this part. In all, TIANDITU-based geographic information system for travelling service aimed to integrate the travelling information resources from national, provincial and municipal levels, and finally realized to provide "one stop" travelling service for users in the end.

One of the anticipation actions that can be done before the flood disaster comes is to determine the evacuation route and evacuation location or shelter for flood relief and spread to the public in order to accelerate the process of evacuation of disaster victims so as to minimize losses from the flood itself. This research was conducted by approaching Geographic Information System (SIG) The purpose of this research is (1) Knowing the flood-prone agihan in Laweyan Subdistrict based on SIG. (2) Analyze the Availability of Shelter Locations (Educational Buildings and Buildings of Worship) of flood victims in Laweyan Subdistrict. It is expected that in the research to know the potential of the best temporary evacuation shelter / protection and evacuation design so that it can be considered and help the relevant agencies, especially local BPBD in order to improve flood mitigation in Sumber Village, Banjarsari District, Surakarta City. To reduce or overcome the impact caused by flood disasters on the comfort and safety of the community in Laweyan Subdistrict, researchers need to raise the title, " Determination of Flood Victim Shelter in Lawean District of Surakarta City Based on Geographic Information System".

In response to concerns regarding the social relevance of North American archaeology, it has been suggested that the tenets of ‘activist scholarship’ can provide a framework for a more publically engaged archaeological discipline. Maps have long been employed in the public dissemination of archaeological research results, but they can also play a role in enhancing public participation in heritage management initiatives. This article outlines how the goals of activist archaeology can be achieved through the mobilization of qualitative Geographic Information Systems practices, with an example of how ‘grounded visualization’ methods were employed in assessing the vulnerability of Inuvialuit cultural landscapes to the impacts of modern climate change.

Underpinning £136 billion of economic activity in the United Kingdom, Britain’s National Mapping Agency is a commercialising public sector organisation having trading fund status and existing in the intersection of two different spheres—the public and the private. Recognised as a leading participant in the geographic information industry, within which it is forging partnerships with key private sector companies, the organisation has enthusiastically grasped e-business as an all-embracing phenomenon and implemented a new strategy that transformed the way it did business. Drawing on longitudinal data gathered over a period of four years, this article explores the processes of strategic and organisational transformation engendered by e-business implementation in this organisation and discusses the successful elements, as well as some of the challenges to its change efforts.

The pace at which cities grow and its impact on heritage management has meant that those heritage assets not linked to the traditionally monumental have been directly doomed to oblivion. The purpose of this article is to present a research methodology backed up by multidisciplinarity and stakeholders’ diversity that allows us to highlight the values and singular aspects of this rural heritage. To achieve this, a methodology was devised that is divided into three phases: mapping of human, cultural, and natural resources based on studies undertaken by the Public Sector Administration, experts, and the citizens themselves. The second phase involved the establishment of what to protect amongst all the stakeholders involved. Finally, the third stage entails integration of the information within an urban development framework. In order to work on the development of a diagnosis from three highly different approaches, Geographic Information Systems was used as information management tools, as a means of contrasting it and performing a comprehensive analysis of the same. The development of such a holistic approach provided a patrimonial map of essential resources in the municipality to be taken into account to shape sustainable development strategies inherent to a rural environment of low density. The lack of this comprehensive approach when managing rural heritage in which citizens take on centre stage in decision-making processes unearths two fundamental issues: firstly, the ascertainment of the existence of cultural heritage hitherto abandoned, alongside the need to endow urban governance powers to the public administration, as it falls to them to spearhead this shift in public management.

Interpretive centers are well-known sources of geographic information—providing visitors with maps and facts about noteworthy places. Yet research on the effectiveness of interpretation in conveying geographic information is limited. Managing natural and cultural resources creates a need to communicate to the public about these places at both small and large scales. This raises the question of how people perceive different types of spaces and how they learn geographic and spatial information. This paper reviews the literature on spatial cognition, providing a theoretical and empirical basis to suggest strategies for interpretation. The recommendations of this paper are to: 1) design geographic interpretation around the three components of spatial knowledge; 2) create interpretive maps by blending the principles of map and exhibit design; and 3) provide visitors with multiple opportunities to learn about a geographic setting. Maps have considerable potential as tools for connecting visitors to the meaning of places.

Across the public sector, Geographic Information Systems (GIS) and spatial analysis are increasingly ubiquitous when making decisions involving people and places. However, historically GIS has not been prevalently applied to the various types of impact assessment. As such, this paper presents findings from a survey conducted in 2011 of 100 local authorities in England to examine how embedded GIS, spatial analysis and visualisation practices are to the process of conducting impact assessments. The results show that despite obvious advantages of applying GIS in these processes, applications employing basic techniques are at best sporadic, and where advanced methods are implemented, these in almost all instances are conducted by external contractors, thus illustrating a significant GIS under capacity within the sampled local authorities studied.
