Description

This unit of competency specifies the outcomes required to develop two-dimensional (2-D) and three-dimensional (3-D) visualisations in a geographic information systems (GIS) context. It requires the ability to apply wide-ranging specialised technical, creative and conceptual skills, a broad knowledge of spatial datasets and accountability for personal and group outcomes. Functions will entail complying with and developing or amending organisational guidelines.

Notes

Elements and Performance Criteria

1Prepare 2-D or 3-D digital elevation model (DEM).

1.1 Computer-aided design (CAD) environment or surface elevation is designed according to organisational requirements and project specifications.1.2 Orientation is established to job requirement.1.3 Views are established to job requirement.1.4 OHS issues are considered at all times.1.5 Skills and knowledge are updated to accommodate changes in operating environment and equipment.

2Create 2-D drawings.

2.1 Spatial computing platforms and software systems are assessed for suitability against specification.2.2 Availability of suitable data is verified with the potential suppliers.2.3 Constraints on use of spatial data are assessed against specification.2.4 Drawing entities and attributes are linked to database attributes to suit project specification.2.5 Detailed views are created using various scales to meet project specification.2.6 Existing 2-D model is modified if necessary to meet project specification.

3Create and modify a 3-D model or DEM.

3.1 Surface elevation is modelled by mathematically defined surfaces or by point or line data and according to project specification.3.2 Products that can be derived from a DEM are determined.3.3 Entities are created in 3-D space to job requirement.3.4 Entities are manipulated in 3-D space to job requirement.3.5 DEM is developed with a range of thematic data and profiles generated and draped over the model.3.6 A contour map of an area is created by employing procedures appropriate to the data format and software.3.7 Slope map of an area is created from gradient and aspect components.3.8 Shaded relief map of an area is created from gradient and relief map representations.3.9 Existing 3-D model is modified if necessary to meet project specification.

4Produce output.

4.1 Linked entities are documented according to organisational requirements.4.2 Drawing files are saved in the appropriate format.
4.3 Physical properties are extracted to job requirement.4.4 Slope map of an area is used for analytical purposes.
