Resource Type

Dataset  

Purpose

PLM25_OVERLAYS is the management overlays dataset which was originally created at 1:100 000, but has been updated to 1:25 000 with VicMap topographic data, vegetation data, aerial photography and reference to the original mapping, gazettals, and management plans. It represents the Reference Areas recommended and approved from various LCC/ECC/VEAC Investigations and legislated under the Reference Areas Act (1978). The now obsolete PLM100_POLYGON was the key dataset assisting public land management activities (such as Park and Forest Management planning and Catchment co-ordination, etc) undertaken by DELWP and showing the underlying land tenure has now been replaced by PLM25.This dataset is a representation of the certified plans - the gazettal and certified plans are the official boundaries.

Supplemental Information

History: Refer to metadata for PLM100_POLYGON, PARKRES, PARCEL_VIEW, VEACRECS25 and PLM100_REFERENCE_AREA and certified plans, Acts and gazettals. Relationship to other Datasets: Developed in conjunction with PLM25, PARKRES and VEACRECS25 . Current Design Issues: Polygons showing boundaries of reference areas proclaimed under the Reference Areas Act 1978 or recommended by LCC/ECC/VEAC and published in the Government Gazette are a guide only. To determine actual legal boundaries, refer to proclaimations in the Government Gazette. Future Design Issues: Linework showing the source of overlay boundaries has been created and annotated, to help clarify questions on topographic or vegetation boundaries, but the certified plans and gazettals are the definitive answer and these layers are only representations of these data sources. Related Documents: None Refer to PLM25, PLM100_POLYGON, PARKRES and VEACRECS25 . Legal data from CLR textual database.

Statement

Dataset Source: Text attributes are sourced from PRIMS and VOTS. Polygons are derived from Vicmap 1:25 000 topographic data, Reference Areas Act 1978 gazettals, management plans, VicMap parcels, EVC data, PARKRES, PLM100_POLYGON, and VEACRECS25. Dataset Originality: Derived 

Description

Collection Method: Gazettals, Management Plans 

Description

Overlay datasets are created in Geodatabases, with polygon layers and seperate linework datasets with annotation. Linework is selected from existing VicMap datasets, EVC dataset, parcels, PLM100, VEACRECS data and added to a layer. Linework is annotated to show its source. Polygons are then created from the linework. The tabular data is then joined from PRIMS and VOTs. Views are exported as shapefiles and processed in ARCGIS to build a appropriate and toplogically correct shapefiles. Rules are used to ensure 1:25 000 boundaries overides 1:100 00 where they overlap due to data sourced from different places. Shapefiles are loaded into Oracle SDE.
