This table will hold polygons depicting indicative extents of the area of the relief feature. Each of these features has some type of non specific but best derived boundary. These geographic relief areas depict features such as plains and ranges. These polygons contain intelligent information including name, parent feature name, feature type & scale use codes enabling flexible, intelligent and cartographic labelling which is both multi scale and non scale dependent.

Abstract:
This table will hold polygons depicting indicative extents of the area of the relief feature. Each of these features has some type of non specific but best derived boundary. These geographic relief areas depict features such as plains and ranges. These polygons contain intelligent information including name, parent feature name, feature type & scale use codes enabling flexible, intelligent and cartographic labelling which is both multi scale and non scale dependent.

Purpose:
The EL_RELIEF_AREA_FUZZY table holds the more indicative natural relief features within
Vicmap Elevation it provides an accurate representation of natural relief features across Victoria, at a capture scale of 1:25,000. It is used in a variety of applications, emergency services, natural resource management, planning and development, and digital map publication.
Geographic Areas which depict such features as ridges, ranges and plains. Originally sourced from annotation layers for use in map labelling there spatial extents have since been modified to better represent their real life extents.
The Geographic Areas data set can be used for all Vicmap Topographic outputs, at any scale and using index or non-index generation processes and hence meets the "one source many outputs" philosophy of Vicmap Topographic mapping. Current products utilizing geographic areas are:
" Vicmap Topographic Hardcopy Mapping Program
Vicmap Topographic 1:25 000
Vicmap Topographic 1:25 000 GeoReferenced
" Vicmap Topographic 1:30 000 online
" Vicmap Topographic 1:50 000
Vicmap Topographic 1:50 000 GeoReferenced
" Vicmap Topographic mapping by centroid
"
Geographic areas can also be used for other mapping products outside of Vicmap Topographic. The scale range of use from 1: 5 000 to 1: 10 000 000, statewide and seamless coverage and dynamic labelling capabilities make it ideal for web mapping systems such as Information Services Branch land Channel and DSE's Mapshare. Any customized mapping project within Information Services Branch, DSE and whole of Victorian Government should gain benefits from using this dataset. Potential duplication of effort will be removed and it will ensure a consistency of information across all map output products.

Data Source:
Dataset Source: Geographic Areas depict such features as seas, bays, inlets, and coves, and ranges, saddles, plateaus, isthmuses and islands and can be divided into relief and hydrographic features. The original source depicting this information was the single format 1:25 000 hardcopy mapping sheets produced from 1975 to 1995. These features are shown as text cartographically placed over the feature extent.
As part of the conversion to digital data process in the 1990s, each 1:25 000 map sheet was scanned. The relief and hydrographic area map textual information was incorporated as annotation as part of the SDMB-T (State Digital Map Base - Topographic) layers MORPTH25 and SHORE25 respectively. Note that this information was created specifically for use at 1:25 000 and was dependent on the 1:25 000 index system
There is no Vicmap dataset that contains spatial information depicting geographic areas. So to display this information for Vicmap Topographic purposes the SDMB_T annotation layers were used. This posed some limitations in its use. For instance the annotation for the text 'PORT PHILLIP BAY" was created over the extent of the feature for every single format 1:25 000 map where the feature occurred. Hence over a Vicmap Topographic 1:25 000 mapsheet, which is two single format sheets side by side, this textual information would potentially be displayed twice. This same annotation may be truncated on the edges of Vicmap Topographic 1:30 000 A4 map sheets (see fig 1.) On the Vicmap Topographic 1:50 000 map sheets the annotation may not be readable due to its reduced size, and may appear several times in the map area.
