A critical review of two texts A host of new technologies such as online services, mobile phones, GPS (Global Positioning System), and high-resolution satellite images have dramatically changed the way in which spatial data are produced, used, and shared. Volunteered Geographical Information (VGI) is a pragmatic approach to obtain free spatial data by citizens’ contribution. Although VGI has applied in various disciplines, VGI practices have just started being used in the land administration system. The core of land administration system is cadastral system. It records the land parcel rights, restrictions and responsibilities. There is a huge tenure gap in the world and current land administration systems are not able to fill this gap. Population growth and urbanization, lack of financial resources, and lack of sufficient professional land surveyors lead this gap to the chasm. This paper will critically review two articles which were written by Basiouka & Potsiou (2012) and Laarakker & Vries (2011) in order to investigate whether VGI is an alternative model for gathering and maintaining cadastral data or not. Laarakker & Vries (2011) conducted a survey in order to identify the potential strengths and concern of VGI in land administration context among the land professionals. The authors introduced the concept of OpenCadaster as an extension of VGI in the land administration domain. In this study, first of all, the main concerns on VGI and open system were excluded through the literature and then the ideas and opinions of professionals were collected through online discussion groups in LinkedIn and Wikimapia.org by raising this question: “Can social media have add value to the formal statutory cadastral systems that exist world-wid... ... middle of paper ... ... of the concern of this approach. On one hand, this information could shows that VGI is really new in the land administration fields. On the other hand, it could reveal that many experts on the land administration fields are not interested in this approach. All things considered, Current land administration problems are not automatically solved only by using VGI. There are many concerns without any regulated procedure. Therefore, all other potential solutions should be aware of the frame changing consequences. Works Cited Basiouka, S., & Potsiou, C. (2012).

...l estate industry. From the decision to lend money for the construction of a new skyscraper in Chicago, to the choice between the corners of a highway intersection for a new gas station, GIS plays a crucial role in allowing the key participants to make more informed decisions. Judging from the incorporation of GIS applications by today’s real estate companies, the importance of this tool will only continue to expand.
...regarded GPS – an indispensable part of GIS. Discussions on cartographic principles, commercial GIS software programs, satellite images, aerial photos, and geodatabases are some of the other conspicuous omissions in this book. There is an inconsistency in the depth of topics explored; for example map projections are explored in great depth, while vector topology is merely glossed over. These omissions and inconsistencies would in my opinion make this book marginally less beneficial to all the three audiences together. However, there is something for all them; structure for engineers, equations for engineers and students, and GIS concepts for students, engineers and users. This book will therefore be undeniably valuable if used to complement the material in some of the other fundamental GIS books in the discipline. It has merits, but there is room for improvement.
* Develop a regional land-use plan in collaboration with local communities, local governments, ministry officials, non-governmental organizations and universities.
Geographers plan new communities, decide where new highways should be placed, and establish evacuation plans. Computerized mapping and data analysis is known as Geographic Information Systems (GIS), a new frontier in geography. Spatial data is gathered on a variety of subjects and input onto a computer. GIS users can create an infinite number of maps by requesting portions of the data to plot.
In law there are two types of land, registered and unregistered. It is necessary to register land so the register precisely reflects the state of the registered property, so it is clear to see who the current owner is and whether there are any third party proprietary interests affecting it; this is important as it would make many lal enquiries easier and will show the property’s reality to any future purchasers. The purpose of land registration according to Gray and Gray (2008) is that “any prospective purchaser of registered land should always be able to verify, by simple examination of the register, the exact nature of all the interests existing in or over the land which he proposes to buy”. There are three main principles of land registration: the insurance principle, curtain principle and the mirror principle. The mirror principle which essentially means that the register reflects reality hence all facts significant to the land title are to be found on the register. The significant facts that should be included in the register are “the owner, the nature of his ownership, and any limitations on his ownership and any rights enjoyed by other persons over the land that are adverse to the owner”. However this is not always the case as some third party proprietary interests override registered dispositions, these are called overriding interests. Overriding interests are binding on a purchaser of any registered land even though they are not on the register.

Building a GIS system from the ground up is a very time consuming and extremely expensive venture. This is why only large metropolitan areas have developed or are developing GIS systems.
The revolution in information and communication technologies has been changing not only the daily lives of people but also the interactions between governments and citizens. The digital government or electronic government (e-government) has started as a new form of public organization that supports and redefines the existing and new information, communication and transaction-related interactions with stakeholders (e.g., citizens and businesses), especially through the Internet and Web technologies, with the purpose of improving government performance and processes (Bekkers & Hornsburg, 2005). Social media has become a central part of how people interact with friends, colleagues and communities.

The purpose of enacting The Land Registration Act 2002, was to combat the uncertainties evolved around the previous Act, Land Registration Act 1925 . The need for reforms was highlighted in a report by Law Commission known as Land Registration for the 21st Century: a Conveyancing Revolution . LRA 2002 repealed LRA 1925, not only simplify the law by maintaining an accurate record of all the rights and alongside interests held by others that affect the land, but also to give certainty the basic concepts engrossed by the 1925 Act as it can be very clearly evident that 2002 Act revolves around the original and principle ideas with amendments.
When learning about the field of land development at University’s, students are taking classes that demonstrate skills and thinking. Individuals have to apply planning concepts about problem solving in regional planning. Plus they have to do a demonstration on designs on regional planning and complete independent research and give group presentations. This experience helps prepare the students for the field and great job opportunities.

On the one hand, participatory approach to land use planning can provide openings for the decentralized administration of land management and enhance legal protection of local land rights through contributing to formal recognition of existing land tenure systems. According to Chigbu et al, (2015) four functions of land use planning that directly links to tenure security. (1) Its capacity to identify or determine land areas, parcels and uses and users. (2) Its propensity to enable documentation of land areas, parcels, rights, restrictions and responsibilities. (3) The opportunities it provides for stakeholder involvement, compensation of claims and community participation. (4) Its impact on land value, land markets and credit opportunities. On the other hand, land use planning, promoting sustainable natural resource use and environmental management are generally part of the mandate of local governments. And these prerogatives often tend to be weakly developed, both legally and with respect to capacity building and methodology (Hilhorst 2010). Unclear property rights and tenure insecurity are the major constraints to the potential of successful land use planning. According to UN-Habitat (2008, p. 17), poor land use planning associated with insecurity of tenure and incompletely specified land rights leads to problems of air and water-borne pollution from agricultural and industrial land use. Though there is a
In order to secure land tenure for the urban informal settlers, different countries have introduced licenses or Certificates in different names. However they all have the same objectives. For instance, in Zambia residents are issued with a 30-year Occupancy Licences while the area undergoes through the process of upgrading. These can be later replaced by certificates of title, which carry the same effect as if the landowner were obtaining a direct lease of the land from the state (UN-Habitat, 2012). In Botswana, Certificate of Use is issued to informal dwellers so as to encourage them on further housing investment (Durand-Lasserve, 2006). In Brazil, Concession of the Real Right to Use is issued to residents. The validity period of these licences varies between 30 and 50 year periods but subject to renew (Van der Molen, 2002).
