Geospatial Data for 4D Land Administration

Dear Colleagues,

Spatial data infrastructures need as a basis reliable and authoritative data that can only be provided by the land administration system. Official registers contain verified data that are generally guaranteed by states. They are the infrastructure for the implementation of land policies and land management strategies in support of sustainable development.

Cadastres, as the core of land administration systems in some countries, have a long history. The data registered in them are burdened with imperfections in the original measurements and in data processing. On the other hand, most countries do not have formally registered land and land tenures, and have a ubiquitous trend of building land administration systems. In both cases, there are numerous challenges in relation to geospatial data, from quality improvement to standardization linked to customer needs designed for sustainable land management.

Cadastres have been temporal databases from the beginning. In addition to the registration of changes, the time when the change occurred was also registered. Geospatial data were two-dimensional without heights. This is now a shortcoming that prevents the more versatile use of land administration systems. The inclusion of the third dimension in land administration is necessary to meet the needs of users. Such development leads to smart 4D land administration. 

In this Special Issue we expect the publication of research results that will provide answers to questions such as:

• How can we improve the quality of existing data in land administration registers?
• How can we improve the semantics and data models in land administration registers to achieve support for the development of 4D land administration?
• What are the needs of users for the implementation of sustainable land management?
• How can we ensure the continuous flow of geospatial data from BIM to land administration registers?
• How can crowdsourced data be registered, and what is their reliability?
• How can a cadastral survey become fit-for-purpose?
• What is the role of land administration in SDI?
• How can land administration contribute to the achievement of millennium goals?
• How can blockchain speed up land administration processes?
• What are the opportunities for using IoT in LAS?

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Land is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
