DIRECTOR OF SURVEYS

• Maintains an archive of cadastral surveys with a Cadastral index using topographic base map (Ward sheets),

• maintains the national geodetic infrastructure• checks and approves cadastral surveys for

registration of titles under RPO, allocates Survey Orders for State lands

• checks and approves cadastral surveys for leasing State lands,

• Hydrographic Surveys• maintains topographical maps.

The Lands & Surveys Division main activities

1. Production and Maintenance of the Cadastral and Topographic databases for Trinidad and Tobago.

2. Establishment and Maintenance of the survey infrastructure for Trinidad and Tobago.

3.Survey of State Lands and lands to be acquired for public purposes.

Based on the responsibility (1) the Division has been the creator and custodian of both Topographic and Cadastral data for Trinidad & Tobago

The Division embarked upon its introduction into the Digital arena in 1994 by beginning the process of creating the first large scale digital topographic dataset derived directly from aerial photography.

Primarily in CAD format, but now is available in both CAD and GIS formats

• The Division further embarked upon digital dataset creation by converting it’s cadastral paper based system into a GIS form managed by the Cadastral Management Information System (CMIS) in 2005.

• Providing parcel based base data coupled with a unique identifier for each parcel (Unique Parcel Identification Number – UPIN)

• Therefore the Division now manages two GIS databases for both the Topographic and Cadastral information.
