Application
This unit of competency supports the application of the use of technology for data interpretation and collation, supervised problem solving, teamwork and interpreting technical data. The skills and knowledge acquired upon completion of this unit would support the needs of employees in the surveying and spatial information services (SSIS) industry sector in positions such as field hands, field work coordinators and data collection officers.

Elements and Performance Criteria
1 | Use GIS software to query spatial data. | 1.1 | Spatial data updates are accessed, read, interpreted and edited to ensure they are in an acceptable format to meet functional requirements. |
1.2 | Entities and attributes are used to display spatial information that will assist in the delivery of spatial information services. | ||
1.3 | Entity and attribute queries of spatial data are used to generate summary results. | ||
1.4 | Results from queries are used to present spatial data graphically according to organisational guidelines. | ||
1.5 | Entity and attribute queries are applied when using univariate statistics to explore the dataset. | ||
1.6 | Routine spatial data problems or irregularities are solved in the course of the activity or via consultation with relevant personnel. | ||
1.7 | Keyboard and computer hardware equipment are used to meet functional requirements on speed and accuracy and according to OHS requirements. |
2 | Solve problems using GIS software. | 2.1 | Existing spatial and aspatial data is adjusted to integrate with new data to meet documentation and reporting requirements and to add to personal learning and organisational intelligence. |
2.2 | Geospatial techniques on appropriate software are used to combine spatial layers data to solve problems, highlight selected data features and improve the visual aspect and understanding of the project. | ||
2.3 | Spatial overlay techniques are used to solve problems and generate results pertaining to the spatial project as specified by relevant personnel. | ||
2.4 | Cartographic integrity is tested and validated to solve accuracy and quality problems. |
3 | Produce reports based on basic spatial analysis. | 3.1 | Map or plans are integrated into project reports. |
3.2 | Results, summary statistics and graphs from a mapping application are incorporated into a project. | ||
3.3 | Legal and ethical requirements are adhered to according to organisational guidelines. |
4 | Archive data. | 4.1 | Spatial dataset to be archived is manipulated where necessary to ensure completeness. |
4.2 | Metadata is created according to accepted industry standards. | ||
4.3 | New and existing spatial data is stored and archival details are recorded according to organisational guidelines. |

Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for this Training Package.
Overview of assessment | This unit of competency could be assessed on its own or in combination with other units relevant to the job function, for example CPPSIS4034A Maintain spatial data. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | A person who demonstrates competency in this unit must be able to provide evidence of: using GIS software solving problems using GIS software producing reports based on basic spatial analysis knowledge of GIS software system. |
Specific resources for assessment | Resource implications for assessment include access to: assessment instruments, including personal planner and assessment record book assignment instructions, work plans and schedules, policy documents and duty statements registered training provider of assessment services relevant guidelines, regulations and codes of practice suitable venue and equipment. Access must be provided to appropriate learning and assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities. |
Context of assessment | Holistic: based on the performance criteria, evidence guide, range statement, and required skills and knowledge. |
Method of assessment | Demonstrated over a period of time and observed by the assessor (or assessment team working together to conduct the assessment). Demonstrated competency in a range of situations, that may include customer/workplace interruptions and involvement in related activities normally experienced in the workplace. Obtained by observing activities in the field and reviewing induction information. If this is not practicable, observation in realistic simulated environments may be substituted. |
Guidance information for assessment | Assessment requires that the clients’ objectives and industry expectations are met. If the clients’ objectives are narrowly defined or not representative of industry needs, it may be necessary to refer to portfolio case studies of a variety of SIS requirements to assess competency. Oral questioning or written assessment and hypothetical situations (scenarios) may be used to assess underpinning knowledge (in assessment situations where the candidate is offered a preference between oral questioning or written assessment, questions are to be identical). Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors, team leaders or specialist training staff. All practical demonstration must adhere to the safety and environmental regulations relevant to each State or Territory. Where assessment is for the purpose of recognition (recognition of current competencies [RCC] or recognition of prior learning [RPL]), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time. In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Assessment processes will be appropriate to the language and literacy levels of the candidate and any cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed. |
