• currency—year (for example, 2006) • resolution—grid size of the raster data; layers in the sample project have been provided at a resolution of 1000 m x 1000 m • lineage—processing completed on the data (for example, source, calculations, software/ commands used) • URL—a website where more detailed metadata may be found. Figure 22 Example of tip file information displayed when accessed through MCAS-S Note: The information in the .tip files for a selected primary input data layer is accessed by clicking the Info button on the left hand interface panel. 5.6 Creating user layers It is possible for the user to create their own layers in MCAS-S by editing any layer in an MCAS-S project display workspace (except multi-way layers). Creating user layers is a way of capturing expert knowledge where other data may be incomplete or unsatisfactory, and incorporating this knowledge into an MCAS-S project. Layers can be created from scratch, with only the boundary of an existing layer used, or edits can be made to an existing layer. To create a user layer, right-click on a layer in the display workspace and select New User Layer. A dialogue box will then appear. Fill the spaces to give the new layer a filename, set the resolution to an existing layer, fill in other metadata and then save the new layer to a group (folder) under Classified Data (see figure 23). The number of classes will be the same as the existing layer and cannot be changed. Under the Data drop-down menu, there is the option to simply copy the existing layer, set the layer to –9999 (no data ready for editing) or set the layer to one of the existing classes (creating a layer of pixels with a default value).
