Range - North-south columns referred to in the Dominion Land Survey. 

Raster - A row of elements, such as pixels on a video monitor. Multiple raster lines comprise the matrix of pixels that form a complete image. Related terms: digitizer (video), grid systems. 

Raster-based Systems - See Grid Systems. 

Real Property - Immovable property (also referred to as real estate or land), as distinct from personal property. 

Rectilinear - Bounded or formed by straight lines. 

Registered Owner - See Owner.

Registrant - The user (person or party) submitting the source documents for registration. 

Registrar - The statutory official in the Land Titles System. 

Registrar’s Caveat - In the old Land Titles System, the Registrar would register a caveat that would, in effect, freeze the title from any future dealing with the lands, until the issue that caused the title to be frozen had been resolved.

Registrar’s Renewal - An instrument that is created internally to cancel an existing title for a title that has been completely filled with endorsements, and issue a new title, that reflects active title information only.
 
Registration Date - The calendar date upon which an instrument (interest) is received and on which it is deemed to be registered.

Registration number - The number assigned to an instrument submitted to the old paper-based system for registration. It is an assigned sequential number made up of a combination of the:
(1) last two digits of the year.
(2) office designation initial(s).
(3) sequential number.

Renewal - See Registrar’s Renewal. 

Renewal Registration Date - The date that a renewal was registered in the Judgment Registry. 

Replotting - The reconfiguration of parcels within a registered Section 104 Plan, by means of filing a replot plan. 

Request (new) - A single cover sheet submitted for processing. 

Request (old) - See Final Request. 

Request Date - On a picture of a parcel of land, the request date refers to the date that the picture was generated. 

Resolution - The accuracy at which the location and shape of map features can be depicted for a given map scale.

Root Mean Square (RMS) - A measure of the amount of "unexplained" variation remaining when a set of tics or control points are registered. A polynomial regression equation is fitted to relate the digitizer co-ordinates to real world co-ordinates. 

Rubber sheeting - The process by which the map features in a slave data layer are assigned new co-ordinates (a mathematical function is calculated) to more closely fit a master data layer based on a set of registration points common to both the slave and master data layers.
