The mechanism for creating strata schemes and strata titles under the Strata Titles Act 1985 as Amended. Strata plans define the lots in a strata scheme (areas owned individually) and common property (areas owned jointly by all lot owners in the strata scheme). Strata lots are limited in height and depth (the stratum of the lot). Strata plans show a building on at least one lot of the strata plan and stratum of the lots is always linked to buildings shown on the plan.
A certificate of title for a lot in a strata scheme created under, and subject to the provisions of the Strata Titles Act 1985 as Amended. Strata titles specify the ownership of the lot, and the lodged and registered interests and claims (encumbrances) against that ownership .

measurement of dimensions (contour, position, boundaries, area, height etc.) of any part of the earth's surface (land or water) or any cultural feature. Depending on the type of survey undertaken and the degree of accuracy required, "surveys" may involve the application of the theory, principles and techniques of geodesy, photogrammetry and cartography.
Survey - Strata Plan
The mechanism for creating survey-strata schemes and survey-strata titles under the Strata Titles Act 1985 as Amended. Survey-strata plans define the lots in a survey-strata scheme, which are the areas in the scheme owned individually. Common property areas owned jointly by all lot owners may, or may not exist in survey-strata schemes and are defined as "common property lots". Survey-strata lots may be limited in height and depth but generally are not. No buildings are shown on survey-strata plans.
Survey - Strata Title
A certificate of title for a lot in a survey-strata scheme created under, and subject to the provisions of the Strata Titles Act 1985 as Amended. Survey-strata titles specify the ownership of the lot, and the lodged and registered interests and claims (encumbrances) against that ownership.
Subsidiary Certificate of Crown Land Title
Certificate of title issued for registration of subsidiary interests (e.g., multiple leases within a single reserve).
A term commonly applied to a large parcel of Crown land which is being disposed of, whether by lease or sale, for subsequent subdivision and sale by the lessee or purchaser for townsite lots. The Land Administration Act 1997 makes provision for this to happen.
The process of transferring back to the State an interest in land (e.g., surrender of freehold).
Short Wave Infra-Red
The term used under the Land Administration Act 1997 in lieu of "resumption" or "compulsory acquisition". It relates to the taking or acquisition of interests in land, whether by agreement or compulsion.
radio signals transmitted between satellites and ground stations.
Tenants in Common
Where there is a desire of two or more people to hold the land in undivided shares. For example X has 1/3 share and Y has a 2/3 share of the land. Both X and Y can transfer their shares to another or others. On the death of one party the land does not automatically go to the remaining partner unless stated in the will.
The Land Administration Act 1997 provides for disposition of Crown land by tender process - the submission of proposals and prices for specified areas of land.
Commonly referred to as ownership, however land differs from goods in that no one person can possess land in absolute ownership. Tenure is the system of holding land for the Crown.
TERRS Tasmanian Earth Resources Satellite Station
satellite data acquisition station located in Hobart, Tasmania and operated by the CSIRO.
Third Party Grants
The federal Native Title Act 1993 provides a way for dealing with Crown land potentially subject to native title, through first undertaking compulsory acquisition. Where the intention is to subsequently grant an interest in that land (e.g., sell it, or lease it) to a private party - commonly called "third party grants" - special provisions apply.

involves establishing the contour level and interval of the earth's surface above and below sea level based on a particular control survey system. These surveys may be done by aerial, photogrammetric and ground survey and involves recording of natural features such as hills, streams, valleys and cultural features, such as roads, bridges, railways, etc. These surveys are used to produce topographic maps.
description or representation on a map of the physical and cultural surface features.
The present system of land title registration used by the Office of Titles. This system has simplified the registration of land dealings and guarantees the title of a land owner. It ensures that a person need not look further than the original Certificate of Title to ascertain all the registered interests in the land.

Trusts - Grants in Trusts
Reserved land may be granted in trust to a party under certain limited circumstances - for example where substantial capital costs require a high order of security, but the developer is of a charitable nature, justifying Government assistance in the form of a low cost grant of land. The Trust secures the land for the specified purpose and prevents its later sale. If sale should be agreed to at a later stage, reference to the Parliament is necessary to remove the Trust, and the sale proceeds are retained by the Crown. Some grantees of Trust land may be governed by Special Acts of Parliament, which convey certain rights in relation to Trust land.
Unallocated Crown Land
Crown land which is not subject to any interest (aside from native title interests) and which not reserved or dedicated.
A reserve which is not formally placed under the control of a management body.
For the most part these reserves are wholly under the control of Landgate.

Vacant Crown Land
Crown Land not currently being used or reserved for any future purpose.

Vesting is a term relating to transfers of ownership or placement of control of land, which depends on the circumstances, as indicated by the following :
1. The act of placing ownership of land in a person or body — for example, ownership may be vested in the Crown of private freehold land designated under the Town Planning and Development Act for public recreation reserves.
2. The act of planning control of Crown land in a government agency for a specific purpose, under a special Act (e.g., a Port Authority Act, or Aboriginal Affairs Planning Authority Act).
3. The act of placing control of reserved Crown land in a specified body, under the Land Act 1933 (e.g., vesting a reserve in a local government). "Vesting" is replaced by "management" in the Land Administration Act 1997.
1. A reserve may be placed under the control of an authority or organisation by means of a Vesting Order issued by order of the Governor in Executive Council. Reserves may be vested in local government authorities, government departments, government instrumentalities, or private incorporated bodies, for example racing clubs and community organisations.
2. The Commissioner of Titles may issue an order vesting freehold land in an applicant.
3. The Courts (Supreme and Family Court of WA), can issue orders vesting freehold land in an applicant.

Verification of Identity
Issued out of the Local Court, a warrant acts in the same way as a caveat, by preventing the registration of documents. It remains effective for a period of four months after issue and may be renewed by lodging a further warrant. It also permits a forced sale of the property, by the Court Sheriff or Bailiff, to satisfy a debt.
