Basic Land and Property Unit (BLPU) A contiguous area of land under uniform property rights.    In the absence of documentary evidence of ownership, or where for administrative purposes a subdivision is required of an area of uniform property rights under single ownership, then the unit shall be defined by its physical features or inferred from occupation or use.
BLPU See Basic Land and Property Unit.
BOAT Byway Open to All Traffic.  BOATs allow the use of wheeled vehicles of all kinds, but is normally used for walking or horse riding.  Off-road driving for recreational purposes often happens along such highways.  Not surfaced and can get very wet and muddy.   Introduced by the Countryside Act 1968.
BS British Standard
BS7666 The British Standard describing how property should be referenced.  "BS 7666 Spatial datasets for geographical referencing".
Part 1: Specification for a street gazetteer (2000)
Part 2: Specification for a land and property gazetteer (2000)
Part 3: Specification for addresses (2000)
Part 4: Specification for recording public rights of way (2002)
To facilitate the creation of the NLPG, a British Standard (BS7666 Spatial datasets for geographical referencing) has been created.  The standard comprises four parts covering Street Gazetteers, Land and Property Gazetteers, Addresses and Rights of Way.  An operational BS7666 compliant LLPG will become an essential prerequisite for ongoing involvement in the NLPG once it has been created.
What does it do?  BS7666 specifies a standard format for holding details on every property and street.  The standard does not differentiate between commercial or residential properties, between occupied, developed or vacant land, between urban or rural or between addressable properties and non-addressable entities such as communications masts.
What does a standard format look like?  As far as properties are concerned, the standard is based on the concept of a land parcel unit known as a Basic Land and Property Unit (BLPU).
A BLPU is defined in BS7666 part 2 as a contiguous area of land in uniform property rights or, in the absence of such ownership evidence or where required for administration purposes, inferred from physical features, occupation or use.
Each BLPU has a unique reference number (UPRN), a spatial reference (grid co-ordinate) and one or more Land and Property Identifiers (LPI).
The LPI is basically the address of the BLPU in a standard format that uniquely identifies the BLPU in relation to a street as defined and held in the National Street Gazetteer (NSG).  The principal components of the LPI are the UPRN from the BLPU, the Unique Street Reference Number (USRN) from the NSG and sufficient elements from the hierarchy of Primary and Secondary Addressable Objects (PAON and SAON) necessary to uniquely identify the BLPU.

Easement A Right of Way for a specific person or organisation (e.g. BT, water company, etc.) for access purposes, e.g. the electricity company can get to their electricity pylons.  (law) the privilege of using something that is not your own (as using another's land as a right of way to your own land).
An easement is either granted in perpetuity or for a term of years and is an interest in land.  Hence the requirement to register an interest with the land registry.  If you search the deeds of a property, the search would show any easements relating to the land in question.
A wayleave however, is a terminable licence, usually on 6 or 12 months notice, allowing for a right of access over land or the right to have equipment on land.  NORWEB's rights are however subject to our statutory rights contained in the electricity act 1989.

Large scale maps A map which views the world from relatively close up.  The map of a housing estate or a house plan is large scale.   In a large scale map the details, the world and a map of the world would be quite large.  Examples are Ordnance Survey's Land-Line, 1:10 000 Scale Raster and ADDRESS?POINT.  Ordnance Survey calls maps that are at 1:10560 scale or larger "detailed products".
LBS Location-Based Services.  The replacement of paper maps with electronic devices that not only allow you to see the area you are in but pinpoint your position, allow you to select map features and display information about them, plan routes, guide you with voice commands and recalculate routes automatically if conditions change.  Alternatively, a map that can automatically find your nearest Italian restaurant, plan the most interesting route there, tell you what is currently on the menu, and allow you to place an order to be ready on arrival.
The technological benefit from LBS comes from making use of the knowledge of the user's location.

Relative Positional Accuracy Relative positional accuracy relates to the accuracy of the National Grid (NG) reference assigned to a BLPU.
Restricted Byway The public's rights along a 'restricted byway' are on foot, on horseback or leading a horse, or by vehicle other than mechanically propelled vehicles.  This last means you can take a pushbike or horse-drawn carriage along a 'restricted byway' but cannot take a motorcycle or other motor vehicle along one.
Right of Way A general term meaning someone or some body is permitted to pass over a stretch of land.  It need not be a "public right of way".  It may restrict access to certain bodies, modes of transport, times of year or  have an agreed deadline.

Shape files "Shape files are made up of 3 separate files - .shp, .shx and .dbf and sometimes you have .sbn and .sbx but these are just locking files, I think - you can ignore them totally.  Of these 3, you can edit the .dbf file using Excel or Access.  From there you can also import ASCII files and merge them.  One important note though, do not sort your .dbf data in Excel or Access or you end up with either corrupt data or wrong indexed shape files."
SLM Street Lighting Management database
Small scale maps A map which views the world from a great distance.  The UK motorway network or the counties of Wales map would be small scale.   In a small scale map the details, the world and a map of the world would be quite small.  Examples are the Ordnance Survey 1:50 000 Scale Colour Raster, Land-Form PANORAMA, Code?Point, Boundary-Line and OSCAR.  The Ordnance Survey calls maps that are at 1:10560 scale or less "business geographics".
Spatial Operators Functions used when querying the spatial objects in a spatial database to see if they touch, overlap, one covers the other, etc.

Vector Images created using mathematical statements that define geometric shapes - e.g. points, lines, arcs, polygons and groups of such objects - rather than pixels.  Each shape has its own attributes (location, size, colour etc.) that can be individually edited.
You can edit move, resize, and change the colour of vector graphics without appearing to lose any quality.  Unlike bitmaps, vector graphics are not dependent on resolution.  You can scale a vector graphic to any size without it losing detail or clarity.  However, the scale of the accuracy of the vector always remains the same: as you zoom in it does not magically become more precise although it will remain clear and of high quality.
Vector images have no 'background' so they can be placed over other images without a white block.
Vector images do not handle items work that is a continuous tone.  For example, altitude has to be represented by contour lines rather than a gradual colour change.  Vegetation types are represented by coloured shapes with definite terminating lines such as an artificial tree line rather than gradual disappearance.
Vector images typically have a relatively small file size, although this is dependent upon the amount of data being represented.  As layers are added so the size increases.  Imaginary features such as boundaries, invisible features such as sewers and buried cable ducts, and point data for assets and events can have potentially limitless growth potential.

WAP Wireless Application Protocol.  A protocol developed to allow intelligent transmission of optimized Internet content to wireless phones.
Wayleaves Right of way through private property for the laying of waterpipes and making of sewers, etc., provided that only the surface-soil is utilised by the proprietor.
An easement is either granted in perpetuity or for a term of years and is an interest in land.  Hence the requirement to register an interest with the land registry.  If you search the deeds of a property, the search would show any easements relating to the land in question.
A wayleave however, is a terminable licence, usually on 6 or 12 months notice, allowing for a right of access over land or the right to have equipment on land.
The Electricity Act 1989 allows additional wayleave rights on electricity companies.
