Guide to LASSI
November 2014
1 Introduction
The purpose of this guide is to provide information on how you can use the latest version of LASSI.
LASSI was updated in October 2014 with improvements in search functionality, user interface and the
way in which data is displayed.
LASSI is a free online web mapping application that can be used to find a parcel of land or property.
It can be used to identify the boundary of a property and those of surrounding properties. This
information can be used to conduct title searches on each land parcel. Users can also learn the
approximate measurements of the land parcel; view or download a basic property report; or, find out
about surrounding infrastructure such as roads or railways and natural features like rivers and lakes.
Additional information on using LASSI is available by clicking on the ‘Help’ button at the top right of
the banner.
1.1 Which browsers are supported?
a) Firefox
b) Internet Explorer (IE) 9 and 10
c) Chrome and Internet Explorer 11 are planned to be supported in the near future.
Users will experience poor response and performance when using the LASSI application on
the IE 8 browser. We recommend you upgrade or switch to the Firefox browser.
1.2 How often is the parcel and property updated?
Currently the parcel and property data is updated every Wednesday.
1.3 How often is the aerial image updated?
The Melbourne metropolitan hi-resolution imagery was last updated in January 2013 and
statewide coverage is based on the 2009 to 2013 Landcover imagery project.
Statewide aerial imagery coverage is made up of a series of projects flown at different times
and scales, which have been mosaiced.
1.4 How often are the base map tiles updated?
The map and hybrid tiles are now updated on a weekly basis with the latest maintained Vicmap
framework data. The update takes place every weekend.
1.5 How to start using LASSI
LASSI is available free of charge from the following URL:
maps.land.vic.gov.au/lassi

application?
The LASSI application consists of the following components:

information pane


2.1 Information pane
The information pane is the area where search data is included; results of searches and
information are displayed in various tabs within the pane.
If there are more tabs than can be displayed, use the left or right arrows to scroll the tabs left
or right to display the hidden tabs.
For quick access to a tab, use the down arrow to display and select from a complete list of all
available tabs.

layers will be selectable.

At zoom scale < 1:250,000, all other vector layers will be selectable, subject to the
individual rules applied to each layer (e.g. parcel layer is only selectable at scale
1:50000 and below in rural areas and 1:5000 and below in urban areas).

2.6.4
Parcel layer opacity
The parcel layer can have its opacity dynamically changed from 100 per cent opaque to 100
per cent transparent. A blue star next to this layer indicates that the layer’s opacity can be
changed.
Changing opacity

To change the opacity, click on the blue star beside the parcel layer.

Drag the slider to set the level of opacity that is desired, between 0
per cent and 100 per cent.
Zero per cent opacity will make the layer completely transparent.
2.6.5
Opacity setting
For the parcel layer, the opacity setting will only affect the fill colour, while the boundary
colour remains solid.

4 How to measure distance and area
To measure a distance on the map, first click on the ‘Distance’ tool from the toolbar. This
opens a new ‘Measure Distance’ tab in the information pane.
Within the ‘Measure Distance’ tab, there is the option to use ‘point
snapping’. Snapping allows you to place your point at the closest
point in the selected snap layer, e.g. When the parcel layer is
selected, the point clicked snaps to the closest parcel boundary
point, providing the point clicked is within the specified snap
distance. To save the snapping options, click ‘Set snap options’
button.
Once the snapping options are set, click on the map to indicate the
first point of the distance to be measured. At least two points must
be provided to obtain a distance measurement.
Within the ‘Measure Distance’ tab, there are also options for removing selected points from
the list of points for a line (e.g. line A in below figure), starting a new line (e.g. line B started
after line A in below figure) and removing all existing points within the tab.

‘Measure Area’ in the information pane.
Click on the map to indicate the first point of the polygon to be measured. At least three
points must be provided to obtain an area measurement. To end the area measurement
process, double-click on the last point of the polygon that is being measured.
