Informal description of the data product

Vicmap Topographic Mapping - Hardcopy is Victoria’s authoritative hardcopy topographic mapping program. It is created using current data from the Vicmap suite of products and comprises 293 map sheets. These maps depict natural features (watercourses, contours, cliffs and tree cover), constructed features (drains, gates, roads, and built up areas) and administrative boundaries (park boundaries and local government area boundaries).

Hardcopy maps are provided at three different scales:

1:25,000

1:50,000, and

1:100,000.

Vicmap Topographic Mapping - Hardcopy product is complimentary to the Vicmap Topographic Mapping – Digital and should be referenced to, to grasp the full scope of the State’s Vicmap Topographic Mapping Program.

Some of the many uses of the maps are emergency management, navigation, recreation, natural resource management, environmental management, infrastructure planning and route planning.

Maps are made available through third party providers and can be ordered online. Hardcopy maps are updated in a 4-7 year cycle.

Specification scope

Title Vicmap Topographic Mapping – Hardcopy.

Alternative title

Vicmap Topographic Mapping. Vicmap Hardcopy Mapping. Vicmap Topographic ‐ Hardcopy Maps.

Abstract Vicmap Topographic Mapping - Hardcopy displays natural and constructed features on the ground including contours, rivers, streams, waterfalls, lakes, vegetation, roads, cliffs, localities, park boundaries, shipwrecks, etc. Vicmap Topographic Hardcopy Maps is a published statewide mapping series of 293 map sheets comprising of two different products (Standard and Special) and three different scales, refer to Table 1.

Purpose

The purpose of Vicmap Topographic Hardcopy Maps is to provide current and authoritative topographic content in hardcopy form for use by, but limited to:

Emergency services Whole of Government – Federal, State and Local Private industry Academia Community group or association, and General public.

Mainly for: Navigation and positioning Emergency management Natural resources management Site selection Tourism Asset/Infrastructure management Route planning Education resource, and Recreation.

All Australian and New Zealand national and state jurisdictions provide topographic mapping for emergency management, government and community use. The Emergency Management Manual Victoria, inacted by the Emergency Management Act 1986 and Emergency Management Act 2013, sets out the Departments responsibility for providing “topographical mapping both hardcopy and electronic.”

Reference systems

Vicmap Data is mapped to the Geocentric Datum of Australia. Data is held in geographic latitude and longitude computed in terms of the GDA at 01 January 1994 (GDA94). Vicmap Topographic Mapping is mapped at MGA Zone 54 and 55 on Universal Transverse Mercator The temporal reference system for Vicmap is the Gregorian calendar. Some maps are still sold in AGD66 until stock is cleared.

Data quality

Accuracy

Standard of accuracy conforms to specifications and classifications AA1 of the Survey Co‐Ordination (Surveys) regulations 1992. That is:

Horizontal Not less than 90% of well defined detail within +/‐ 12.5 metres of true position at map scale.

Vertical Not less than 90% of elevation within +/‐ half of contour interval.

Vicmap Topographic Mapping – Hardcopy has been built on the existing Vicmap suite of products and therefore retains the respective products relative positional accuracy and completeness.

Vicmap Topographic Mapping – Hardcopy relies on the QA of the source Vicmap Foundation Data for data integrity.

The following procedures are undertaken as normal update/maintenance routines, to ensure conformity of the maps to specification:

1. Any changes to Vicmap Foundation Data structure that may impact on mapping will be implemented in the mapping program, if releveant, and reflected across all stewide products.

2. Even though the generation of Vicmap Topographic Mapping ‐ Digital Products is fully automated, a QA process is carried out where between 5% and 10% of the mapsheets are visually checked. Any issues discovered in this process will be reflected statewide in the digital products as well as the hardcopy products as they both utilize the same generation mapping system.

3. Each mapsheet updated for the Hardcopy program is rigourously checked. Any issues discovered in this process will be reflected statewide in the hardcopy mapping products

Data capture

For more information on the data please refer to the relevant product description for each of the framework layers

Data maintenance

Vicmap products can change under one of the following three terms:

Vicmap maintenance - The incorporation of new data to an existing dataset via an M1, spatial change requests or scheduled Custodial supply. No changes are made to the data or object model, therefore does not require change management processes. Additions can be seen in the weekly Vicmap update.

Vicmap Improvements – Changing existing data, example the moving of a feature or adding of attributes. Typically carried out as part of a project through the provision of new Custodial data requiring change management.

Vicmap upgrades – Significant changes to a dataset that may see existing data over a large area replaced and/or may require the data model changed. Change management processes are applied.

Approximately 5% of all maintenance advice notices processed are separately audited by DELWP to confirm accuracy, completeness and correctness in the capture process.

Vicmap Topographic Mapping maintenance

Vicmap Hardcopy Mapping is updated every four to seven years. Table 3 displays the currency of the maps sheets as per Jan 2016.

High turnover maps titles (sales of over 100 per year) are printed using offset press. Map titles selling less than 100 per year are produced on demand using in house large format plotters.

Appendix C: Product content & generalisation Hardcopy maps at a scale of 1:50,000 is derived directly from Vicmap Topographic Mapping 1:25,000. Only the cadastre has been removed. All line networks, roads, contours, watercourses etc, have been retained with no line work generalisation. The most significant generalization has been in the display and position of labels. Due to space issues some roads will not be labelled in order to retain a legible and high end cartographic map output. This is most evident in the labels of roads in built up areas. (see diagram 7)

1:25,000 1:50,000 Diagram 7. Comparison of 1:25k and 1:50K :Vicmap Topographic 1:25 000 8225-1-S and Vicmap Topographic 1:50 000 8225-N

Hardcopy maps at a scale of 1:100 000 have been derived directly from Vicmap Framework data In order to depict this information (captured nominally at 1:25 000) at 1:100 000 and still have a legible, high end cartographic product, several generalisation methods were implemented:

Elimination: Data that was deemed non vital and would cause congestion on the map if displayed was removed. e.g. spot heights, building points, monuments and silos.

Filtering: Data that was deemed vital but would cause congestion on the map if displayed in its entirety was filtered. This methodology required the data to be structured in order to apply the filtering. e.g. local roads are displayed but not labelled, water bodies less than a certain area are not displayed and only 50 metre contours are displayed.

Symbology: Data that was deemed vital but would cause congestion on the map if displayed in its entirety and was unable to be filtered was displayed with changes to the standard topographic symbology. e.g. All rivers and creeks were shown but with a lighter blue than standard.

Cartographic Representation: Essential spatial point data was cartographically displaced to avoid overlapping symbology. e.g. Emergency symbology was displaced.
