Surveying & Mapping Flashcards
What Licences are required to use OS Promap, Land App?
Promap:
PMCL - Paper Map Copying Licence
Land App:
PSGA License - Public Sector Geospatial Agreement
What detail is required for a Land Registry Compliant Plan?
Must be at an stated appropriate scale
Must contain North Point
Must contain scale bar?
Must show the extent of the property
The plan must be in show sufficient detail of surrounding features
Have a title block
What are the scales commonly used and for what purposes?
Urban Properties - 1:1250 & 1:500
Rural Properties - 1:2500
How are boundary responsibilities noted on plans?
With a T mark.
The mark will be on the side of the boundary where the responsibilities lies
What is the significance of the redline boundary on a plan?
LR Plans - denotes ownership
Planning - shows the land subject to the development
Tenancy Plans - Land subject to the tenancy
How are the following detailed on an OS Map?
Bridleways - Long green dashed lines
Church with a tower & spire - black filled in circle with a cross attached
Church with a tower - Black filled square with a cross attached
Pond - Blue filled circular symbol
Site of Antiquity - Gothis typeface or specific symbols
Beach - light orange or yellow tan colour
Scree - series of small irregularly shaped grey dots.
Orchard - green polygon
How is accuracy determined, how would you check this in the ground?
Comparing measurements taken from a scale map to the real life measurements on the ground. Using a measuring wheel or lazer measure. These can be checked by using triangulation from a fixed points
How would you check a boundary/feature/land parcels size on the ground?
Print off a scale map and compare real life measurements. Use triangulation from fixed points. Or alternatively employ the services of a land surveyor to use GPS (Global Positioning System).
FBT Plans what was required?
A plan to show the land subject to the tenancy, which showed the land parcels detailed in the schedule of land in the FBT.
What was included on the plans?
The land subject to the tenancy which was shown by a redline boundary.
North point.
Title Block
Scale
What scale was used?
1:2500
What detailed was required?
Redline to delineate the land subject to the tenancy.
Field parcel numbers and acreage.
North point
Title block
How did you prepare LR Plan for Land Transfer, land to be retained and sale of pasture land?
I obtained a scale plan from promap showing the land which had to be registered. Plotted the redline boundary for the various maps. For the land retained I showed a right of way along the driveway shaded in light red.
What Method did you use?
Promap
What scale did you use & why?
1:1250 for land retained
1:2500 for land to be transferred
1:2500 for land to be sold
These are the recognised scales and it showed sufficient detail for the land to be identified.
What are the features/advantages of promap?
OS Mapping
Can generate scale maps
Can customise maps with scale annotations & txt
Title Fill - recognises LR titles and transfers them to the plan
Aerial photography
Provides access to up to date, accurate & fully licensed data.
Take measurements from maps.
What feautres were required on the map?
North point
Scale Bar
Title Block
Sufficient detail so he property can be identified
Dry Storage Shed Planning application what was required on the location plan?
The plan showed the redline development boundary, the position of the dry storage shed, location of the indicative soakaway, access to the highway.
How did you measure the site boundary?
The development site boundary was measured using a measuring wheel taken from the fixed point using the shed measurements.
How did you establish a fixed point?
I used the corner of an existing building as this point was unlikely to change.
How did you annotate the plan?
I annotated the plan using promap.
The building was shown as a solid red rectangle
Access to the highway was shown by marking the existing access from the highway through the farmyard with a redline polygon with red hatching
circle with red hatching to show indicative soakaway and arrows to show direction of the flow
Blue line to show land owner by the applicant
The plan showed a north point, scale bar and title block.
