List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 data maintenance requirements. | 1.1. | Data maintenance objectives and constraints are identified and documented in consultation with appropriate persons. |
| 1.2. | Data system is analysed to determine components to be maintained according to project objectives. |
| 1.3. | Maintenance techniques are determined and evaluated according to organisational requirements. |
| 1.4. | Work is allocated to appropriate persons and supervisory processes are implemented to ensure work is completed within time available. |
| | | |
2. | Confirm reliability of spatial data. | 2.1. | Spatial data updates are accessed and checked to confirm currency and relevance, and are recorded according to organisational requirements. |
| 2.2. | Spatial data is checked and edited to ensure it is compatible, and in an acceptable format according to project requirements. |
| 2.3. | Integrity and consistency of data are maintained according to organisational requirements. |
| | | |
3. | Replace spatial data. | 3.1. | Spatial data is amended and replaced according to project and organisational requirements. |
| 3.2. | Existing and new data is edited, prepared and integrated according to project requirements. |
| 3.3. | Spatial datasets are tested and validated to ensure integrity, quality and currency according to project requirements. |
| 3.4. | Documentation is amended and updated according to organisational requirements. |
| | | |
4. | Carry out backup and recovery of spatial data. | 4.1. | Data backups are implemented to ensure data is accessible in contingency situations according to organisational requirements. |
| 4.2. | Backup system is tested to ensure that data can be retrieved, and any problems are resolved or contingencies managed according to organisational requirements. |
| | | |
5. | Archive spatial data. | 5.1. | Spatial dataset to be archived is checked for completeness and manipulated where necessary. |
| 5.2. | Metadata is created according to organisational requirements. |
| 5.3. | Archived spatial data is stored in a secure location, and details are recorded according to organisational requirements. |
