An approach to effective land registration based on the satellite photogrammetry : case study in Baharly, Ahal Velayat, Turkmenistan
Yoo, Hyunil & Handon Ju
With the emergence of high-resolution imagery in the satellite photogrammetry within the order of one-meter or less, it has been regarded as a new area of practice to handle mass data in a cost-effective and time-saving way. Accordingly, it has been utilized in many areas, especially in the geo-spatial information industry, e.g., topographic mapping, land use analysis and monitoring, land use planning, and disaster research. As a matter of fact, while the satellite photogrammetry has remarkably contributed to the geospatial information industry, it has slightly played its role for the cadastral mapping purpose. This is because, in terms of positional accuracy, it does not meet with the criteria required by cadastral jurisdictions where there are basically strict standards as a result of protecting land ownership. What is more, a crucial issue is that the identification of the parcel boundary only relies on clearly visible boundary features or corners from the satellite imagery unless otherwise significant follow-up ground surveys are performed to check out every actual legal boundary points; consequently, it could bring in inconsistency with already existing legal boundaries. However, in the case where a wide range of areas are not entirely registered yet or are required to be newly registered for land use information management rather than determining private land ownership with high positional accuracy, the satellite photogrammetry could be an extremely useful tool in this situation. In particular, where a large number of parcels have to be registered, it can be undertaken with lower cost in a less time-consuming than other methods.
