Land and Survey Spatial Information (LASSI) is a free, web-based mapping platform that supports the day-to-day work of surveyors, councils, government agencies and the public by providing access to authoritative land, survey and place name information.

LASSI allows users to search, view and export information about Victoria's:

  • Crown and freehold parcels
  • survey marks
  • officially registered place names.

It can also be used to view or download property reports and identify surrounding infrastructure like roads and railways.

LASSI brings together 4 mapping systems into a single, future-ready platform:

  • LASSI
  • LASSI-SPEAR – property parcels and surveying information
  • VICNAMES – the official Register of Geographic Names in Victoria
  • Survey Marks Enquiry Service (SMES) – find and add survey mark information.

Using LASSI

LASSI is accessed through a single online platform that supports different enquiry types depending on what you need to do.

When you enter LASSI, you choose an enquiry type:

  • Property Enquiry – search and export land and property information (LASSI and LASSI-SPEAR).
  • Survey Mark Enquiry (SMES) – search the official register of survey mark information and submit updates.
  • VICNAMES Enquiry – search the official Register of Geographic Names and contribute historical information.

Each enquiry type opens a tailored map view with relevant layers, tools and search options.
