Q

What is the role of GIS in land and surveying?

A

Geographic Information System

Hardware and Software that stores, manages, analyses and visualises geographic data

You layer your data, survey data, water features, boundaries, addresses, transportation, elevation, and images to create a GIS model

Q

What surveys would you typically look at in a development?

A

Pre-Construction:
- Topographical survey / land survey
- Geotechnical survey / ground investigations
- Bathymetry survey
- Ecology survey
- Tree survey
- Underground utilities survey
- UXO survey

Assessments:
- EIA
- Flood risk assessment
- Traffic impact assessment
- Historical buildings assessment

Redevelopment:
- Structural survey (for redevelopment)
- Asbestos survey (if building built or refurbished before 2000)

17
Q

What is a CAD drawing?

A

Computer-aided design

Digitally create 2D drawings and 3D models of real-world products before they are manufactured e.g. technical architectural drawings

Typically use AutoCAD for architectural drawings

18
Q

What is a Revit model?

A

Used to model structures in 3D

19
Q

What is a geotechnical survey?

A

Tests physical properties of soil earthworks and foundations for proposed structures

20
Q

What is a bathymetry survey?

A

Type of hydrographic survey which map out details of underwater terrain, illustrating depth and land that lies underneath the water

21
Q

What does the RICS Professional Standard: Measured Surveys of Land, Buildings and Utilities (3rd Ed. 2014) set out?

A

Information on:
- Project information
- Survey accuracy, control, coordinate grid and datum
- Topographical surveys
- Measured building surveys
- Underground utility surveys
- Monitoring and deformation
- Deliverables

22
Q

What is GNSS?

A

Global Navigation Satellite System e.g. GPS

23
Q

Under GIS, what are the types of data?

A

Vector Data - Points, lines and polygons with vertices (e.g. administrative boundaries are polygons, while fire hydrants would be a point, roads are line data)

Raster Grids (grid data) - Satellite images, aerial images, digital elevation models

Visualisation data - locations on a map (choropleth maps use colour, heat maps use shading, isoline maps use lines)

GIS data - Use to find find meaningful information from data e.g. shortest route to work

24
Q

What is included in a topographical survey?

A
  • Get existing conditions of ground
  • Used to decide what to do with land, e.g. development
  • Look at above ground features and utilities underneath
  • Remote sense data, 3D scans, drones can be used to collect data (data from range of sources)
25
Q

What is an easement?

A

An easement is a nonpossessory right to use and/or enter onto the real property of another without possessing it (e.g. Deanfields driveway)

26
Q

What RICS Guidance should you follow when reviewing surveys and maps? When was it published and what edition is it?

A
27
Q

What other RICS publications should you be aware of?

A
28
Q

If you were asked to draw a plan to scale of a development plot, how would you do it?

A
29
Q

What is a Topographic Survey?

A

Type of survey that maps the boundaries, features and levels of a site

30
Q

What is CAD and when would you come across it?

A

Computer aided design used for architectural drawings
