Why is this a key indicator of our performance?

The State Land Information Capture Program (SLICP) comprises components of a work program for producing up-to-date, accurate land information data sets to meet customer needs. It is negotiated with the independent Western Australian Land Information System (WALIS), a consortium of government agencies that use the land information. The extent to which the SLICP is delivered is an indicator of the currency of the data and therefore the effectiveness of DLI's land information base

How was the indicator derived?

With a specific amount of money available in a year, the SLICP is a calculation of the amount of work able to be completed. The proposed program is then agreed with key WALIS agencies. The various components of the required work are recorded in a job tracking system, including the time taken and the direct cost involved.

The percentage completed for each of the component programs is averaged to attain the percentage of overall program completion.

What does this indicator show?

Overall, 98% of the SLICP has been achieved. Of the ten discrete components of the 2004-2005 SLICP, only two have not achieved their individual targets.

Comments on each component follow.

Topographic Data Capture

The Topographic Data Capture program achieved 100% of the target of 270 large-scale map tiles for the metropolitan area and selected country towns. The 2004-2005 program was completed under a one year contract with provision to extend for a further four years.

Spatial Upgrade

The Spatial Upgrade Program updates the spatial cadastral database for specific areas of the State each year, and the entire State will be upgraded over time. During 2004-2005, 100% of the planned work for the year was completed. At 30 June 2005, 74.3% of the entire State has been upgraded to survey accuracy.

Ortho-image/mosaic Production

The Ortho-image/mosaic program revises and expands the existing geo-referenced image coverage of the State each year. During 2004-2005, there were 29,380 images rectified, which is 18% more than the estimated 25,000. Contributing to this was the increased availability of aerotriangulated images.

Aerial Photography Capture

The 2004-2005 Aerial Photography program of 127 SLICP projects was successfully completed. Additionally, 31 self-funded projects for other government agencies were completed. Overall, 37,322 of an estimated 38,730 frames of photography were captured.

Property Street Addressing

The Property Street Address program included rural and metropolitan/urban addressing. The program for 2004-2005 maintenance resulted in 45,236 new or amended addresses being included in the database, exceeding the target of 45,000.

Locality Boundary Capture

Locality boundaries have now been determined for all 144 of the State's local governments. During 2004-2005 the 43 remaining localities in the final five local governments were completed and amendments made to the boundaries of 33 localities.

Digital Elevation Model Production

Improved DEM pre-processing activity enabled the production of 21,599 Digital Elevation Models (DEMs) exceeding the 15,000 target by 44%. The continued refinement of processing software parameters and terrain type was also a factor.

Aerotriangulation Adjustment

Providing the fundamental spatial control link between aerial photography and ground survey coordinates, the aerotriangulation program supports and influences all other geo-referenced topographic and image data activities. Improving on last year's performance, the 2004-2005 program achieved 28% more than the estimated 29,000 images due to the combined effects of low resolution images and digital image handling capability.

Road Centreline Maintenance

Validation, maintenance and revision of the Road Centreline database for metropolitan, outer metropolitan and regional areas in 2004-2005 achieved 18,023 road segment actions, reaching 90% of the 20,000 estimated. This is an acceptable outcome against the annual estimate of an activity that contains varying complexities of road centreline data and which is also impacted by the number of land subdivision surveys that may be lodged with the department. In future, this service will be absorbed into the recently approved Road Centreline Quality Improvements initiative.

Digital Aerial Photography - Increase in State Coverage

The annual program of digitising new aerial photography exceeded previous years. This supports the initiative for electronic access to land data and customised digital products. A proportion of this program provides digital images for areas of the State not previously available in digital form. Priorities for revision of existing areas impacted the amount of new cover achieved. The State's digital coverage increased during 2004-2005 by 38 of an estimated 44 x 1:100,000 scale map sheet areas. This equates to 3.8% of the entire State and achieves a total of 41.04% digitised coverage.

Effectiveness Indicator 2 of 2 and output quality measure (audited by the Office of the Auditor General):

Claims against registered interests, as a result of fraud, negligence or errors, settled by the Crown
  Actual 2002-2003 Actual 2003-2004 Target 2004-2005 Actual 2004-2005
Number of claims settled by Crown 0 0 0 0

Why is this a key indicator of our performance?

The indicator provides a measure of the State's success in maintaining an accurate land titles register. It shows the settled claims against the State arising from fraud, negligence or errors involving the certainty of land ownership within the State.

How was the indicator derived?

The indicator is derived from a register that records new, current or rejected claims made for monetary compensation against the State concerning registered interests in land.

The following definitions apply:

What does the indicator show?

The absence of successful claims indicates that no significant underlying trend involving fraud, negligence or errors is apparent.

Key Effectiveness Indicator (1 of 2) Average cost per land registration action.

  Actual 2002-2003 Actual 2003-2004 Target 2004-2005 Actual 2004-2005
Number of land registrations actions 1,892,461 1,979,902 1,849,475 2,042,270
Average cost per land registration action $24.28 $24.36 $26.81 $25.30

Why is this a key indicator of our performance?

Land registration actions include a range of activities associated with registered land transactions. The most common include document searches, examination and registration of interests on land. The last two involve incorporating changes made to a Certificate of Title. Typically, changes concern land ownership details on a title, applications for a new title for subdivisional land development, caveats, leases, power of attorney, and other minor adjustments to titles.

The indicator provides a measure of the full cost of recording on Government guaranteed land titles the range of interests, boundaries and ownership relevant to that land. This is a clear indicator of the efficiency with which the land registration system and service is maintained.

How was the indicator derived?

The number of transactions is derived from a recording and checking system that reports the number of:

The cost of registration actions includes all direct costs and an appropriate share of indirect and overhead recurrent costs. The cost of land registration actions is recovered via charges to users for each transaction. Each charge is calculated on a full cost recovery basis.

What does this indicator show?

DLI dealt with record numbers of registration transactions this year as high levels of property market activity continued. The indicator shows that because the number of registration actions was 10.4% higher than the target, the cost per transaction decreased by 5.6%.

Key Effectiveness Indicator (2 of 2) Average cost per land information action.

Average cost per physical land information data set maintained and developed
  Actual 2002-2003 Actual 2003-2004 Target 2004-2005 Actual 2004-2005
Land Information Actions n/a n/a 520,118 658,733
Average cost per land information action n/a n/a $38.95 $32.04

Why is this a key indicator of our performance?

This is a new efficiency indicator introduced in 2004-2005. It replaces the following indicators:

Land information actions include a range of activities associated with the capture, production and maintenance of physical land and land boundary information in DLI's datasets. These datasets include information about::

The indicator provides a measure of the full cost of maintaining an up-to-date Government land information base and the costs involved represent a key indicator of efficiency.

How was the indicator derived?

The number of actions is derived from recording systems that report the number of:

The cost of land information actions includes all direct costs and an appropriate share of indirect and overhead recurrent costs.

What does this indicator show?

As this is a new efficiency indicator introduced in 2004-05, comparison is not available. The number of actions achieved was 26.6% higher than the target, resulting in the average cost per transaction being 17.7% lower than anticipated. Continuing technology improvements; refinement of processes and additional resources dealing with land boundary information actions contributed to the significant variance from the target. The target estimated for this measure has been improved for 2005-2006.
