Application
This unit of competency specifies the outcomes required to design spatial data storage systems to meet client requirements. The unit covers analysing client needs and storage requirements and assessing the feasibility of those requirements against organisational budgets, resources and priorities. It also covers planning the system design; scheduling development; and creating and testing prototypes where standard formats are unsuitable. The unit requires the ability to negotiate storage requirements and design solutions; and to seek agreement on the final design, as well as feedback from end users, as the basis for implementing improvements to the storage system.
The unit supports those who work in a lead role in a surveying or spatial information services team in areas such as surveying, town planning, cartography, mapping and geographic information systems (GIS).
No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. | ||
1. | Determine spatial data storage requirements. | 1.1. | Requirements for spatial data storage are determined in consultation with appropriate persons. |
1.2. | Audit of existing spatial data sources is conducted to determine their suitability, useability, dependencies and adaptability in meeting storage requirements. | ||
1.3. | Feasibility of storage requirements is assessed against organisational budget, resources and priorities; and documented according to organisational requirements. | ||
2. | Plan storage system design. | 2.1. | Plan is developed based on functional requirements of storage system and detailing spatial data dependencies. |
2.2. | Appropriate spatial data storage environment is determined according to data and organisational requirements. | ||
2.3. | Schedule for introducing data storage system is developed and communicated to appropriate persons. | ||
2.4. | Prototype is created and tested, or a standard format adopted, to confirm that design meets functional requirements. | ||
3. | Finalise storage system design. | 3.1. | Final design of spatial data storage system is negotiated with appropriate persons according to organisational requirements. |
3.2. | Final design is agreed and accepted, and documentation is created according to organisational requirements. | ||
3.3. | End users are canvassed to determine effectiveness of designed spatial data storage system. | ||
3.4. | Feedback is analysed and used to make improvements to storage system according to organisational requirements. | ||
Evidence of Performance
A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit. The person must also design spatial data storage systems for two different clients.
While designing the above spatial data storage systems, the person must:
