Subject Matter

1 Terravis is the electronic information portal for land registry information operated by SIX Terravis AG, accessible via retrieval.

2 This Ordinance governs the use of Terravis by cantonal and communal authorities.

3 Authorities are defined as

a) Organs of the Canton, its institutions, and its public corporations;

b) Organs of the municipalities and districts, their institutions, and their public corporations;

c) Third parties, to the extent they are acting in fulfillment of public-law duties assigned to them.

### Legal Effects and Warranty

1 The land register data obtained via Terravis constitute a mere information tool.

2 No warranty is given for the accuracy of the data retrieved. Legal effects are solely produced by land register extracts certified by the Land Registry Office.

User Management and First-Level Support

1 The Security Department is responsible for activating users reported by the authorities in Terravis, user management (mutations), first-level support, and implementing the orders of the Land Registry Inspectorate (§ 10 para. 2).

2 The Security Department determines the form and content of user registration.

II. Access to Terravis

Principle

The authorities only have access to those land register data that they require for the fulfilment of their legal duties. The scope of the access rights is determined by the respective legal bases.

User Roles and User Profiles

1 User roles describe the possible access rights and are listed in Annex 1. The assignment of user roles (user profiles) is governed by Annex 2.

2 The Security Department maintains a register from which it can be determined at any time which users possess which profile. Information concerning exited users must be retained for at least two years.

3 The Security Department shall update Annexes 1 and 2 in the event of changes to the underlying principles of user roles and user profiles.

Search Function

1 Queries in Terravis, with the exception of those regulated in paragraph 2, can

only be carried out using property-related searches (Search Function S1).

2 The additional person-related search in Terravis (Search Functions S2/S3)

can be granted to the following authorities

a) Land Registry Offices (with Search Function S3);

b) Debt Enforcement and Bankruptcy Offices (with Search Function S2);

c) Public Prosecutor's Office (with Search Function S3);

d) Cantonal Police (with Search Function S3).

Access Identification

1 Access identification consists of the name, username, and password of the authorized public official, which are issued by the Security Department. The username and password are communicated to the user separately.

2 The password must be treated confidentially. It must be changed immediately upon receipt or at the latest within 10 days. The user will be periodically prompted by an automated system to adjust their password.

3 The username and password may only be used personally and must not be passed on. It is not permitted for two or more persons to work under the same name.

Duties Pertaining to Terravis Use

1 The authority is obligated to take all measures necessary to ensure data

protection. Specifically, it must

a) through adequate protection of its systems, prevent them from being misused as a platform for attacks on the land register systems or from making data accessible to unauthorized third parties;

b) inform its personnel of the conditions associated with the authorization and ensure their compliance;

c) ensure that only authorized data retrievals occur and that the data is used for its intended purpose;

d) notify the Security Department of the departure of employees using Terravis and of any use-relevant changes in function.

2 If an authority identifies unlawful data processing, particularly unauthorized data access, it must immediately notify the Land Register Inspectorate.

Control of Data Access

1 All inquiries in Terravis are automatically logged by the system (Art. 30 para. 1 LRO). The access logs are stored for two years and periodically checked by the Land Register Inspectorate on a random sample basis.

2 The logs are exclusively accessible to the Land Register Inspectorate, which monitors the specifications for the use of Terravis.

Abuse

1 The permissibility of inquiries is governed by Art. 26 et seq. LTR.

2 The Land Register Inspectorate is responsible for ordering measures in the event of

abusive processing of the obtained data and makes final decisions

thereon. It may restrict access authorization in the event of a breach of user obligations

and order the withdrawal of access authorization in the event of abusive processing or use of the data

(Art. 30 para. 4 LTR).

3 Renewed access authorization will be granted when the authority has taken sufficient

precautions to comply with legal obligations in the future.

Einrichtung Schnittstellen

1. Establishment of Interfaces

1 For the updating of land register data retrievable via WebGIS (Art. 26 para. 1 lit. a GBV), a technical interface to Terravis can be established (§ 6 para. 1 Ik-GBV).

2 For the examination of electronically submitted building applications via eBau, a technical interface to Terravis can be established (§ 6 para. 1 Ik-GBV).

3 For the updating of owner address data of the land register information retrievable via WebGIS, a technical interface to GemDat can be established.

Data Security

Insofar as cantonal regulations or directives regarding data security are lacking, the provisions and directives applicable to the security of federal information technology systems and applications shall apply mutatis mutandis.

Costs

1 Access to land register data under this Ordinance is free of charge.

2 Enquiries to first-level support (Art. 3 para. 1) are free of charge.

3 Direct enquiries to second-level support (SIX Terravis AG) are prohibited. If

such enquiries are nevertheless made, they shall be subject to a fee and
