Cadastral Resurveying

Taiwan's cadastral maps were drawn up during the Japanese occupation and have been in use for more than 100 years. Over this long period the drawings have suffered from shrinkage and serious damage, and further factors such as the division of land parcels and changes in natural topography and artificial boundaries have meant that the maps often don't correspond to reality. This, in addition to minor factors related to the technology, equipment and scale used at the time, has led to maps whose accuracy struggles to meet modern demands. The grave effect this has had on public and private property rights has necessitated a resurvey to correct inaccuracies, eliminate boundary disputes and guarantee the legal property rights of Taiwanese citizens.

When landowners receive notification of a cadastral resurvey, if no boundary disputes exist with owners of the adjacent land, they should work together with all the adjacent landowners to identify boundaries and install boundary markers. In the event that boundaries cannot be identified, landowners may advocate the assistance of land surveyors, who will take into account reliable materials such as the old cadastral maps as reference.
On the date and time specified in their letter of notification, landowners are requested to bring their Taiwanese ID, personal seal and the letter of notification to the site and to give the cadastral surveyors a detailed account of the location of boundaries. In addition, during the survey they are requested to confirm each item contained within the inspection list; after confirming that there are no errors, landowners should sign their name or add their seal.
Should a dispute over boundaries arise with adjacent landowners, it should first me mediated by cadastral surveyors and the Land Office. If, following this, the dispute still cannot be resolved, mediation will be provided by the County Property Dispute Mediation Committee.
If landowners are still dissatisfied with the committee’s findings, they should petition the judiciary authorities to determine boundaries within 15 days of receiving notification.

Benefits of the resurvey:
1. During the cadastral survey, a free boundary marker will be provided once the borders of the land parcel have been established. The boundary marker will be installed by all landowners, and guarantees the property rights of the public.
2. During the cadastral resurvey, the land parcel boundaries and parcel number will be re-compiled. In addition, land owners can apply to merge fragmented parcels of land , which will solve the problem of highly disorganized parcel numbers.
3. The scope of cadastral survey will be within city planning limits. It will include cleaning, complementary construction and joint surveying, which will make the cadastral map consistent with urban planning – facilitating urban planning arrangements and the implementation of land development and construction.
4. Land within the resurvey area that hasn't been registered will be fully cleaned and, following the legal survey will be registered as nationally-owned. This will create a sound cadastre and facilitate the management and handling of public property.
5. The resurvey will involve the use of numeric measurement techniques, and each boundary point will be allocated a marker value. Computers will allow the cadastral maps to be viewed at different scales, which will avoid errors caused by paper shrinkage, hand-copying and misreading of numbers that occurred in the original cadastral maps. This will not only expand the function of the cadastre, but also means it can be used for reference purposes – greatly increasing its administrative efficiency and service quality.
