The toolbox is where you get access to the drag-and-drop blocks. The menu expands on a click so that you can see the relevant headings. Clicking on a heading exposes the blocks.
Click on the block you need, or drag it into the workspace. (The workspace is the blank canvas panel to the right of the toolbox).
The blocks are categorised, and colour coded, based on the three steps normally required to run a workflow. It is strongly advised that you drag and drop your blocks in this order:
Step 1: INPUT
- These blocks bring in the data that you select.
- The main data block block determines the type of data that is to be used. Notice how it is a container block with space to add other blocks within it.
- The other blocks then select for different features of the data, such as the location, the time period, or other properties of the data.
- A full description of all the INPUT blocks is given in this article.
Step 2: ANALYSE
- If you want to extract information or further investigate the data you selected in Step 1, then you will need to choose a block that applies the required processing step. See this article on the analytical steps available.
- This step is optional depending on what workflow you are trying to create.
- If you are simply visualising the data, rather than manipulating it in some way, you do not need an ANALYSE block.
- A full description of all the ANALYSE blocks is given in this article.
Step 3: OUTPUT
- To view your data, or the results of your analysis, you need to select an output block.
- You can also add dashboard blocks that generate tables and graphs.
- You can also add a download block to save any of the map outputs as a GeoTIFF (note that not all users have access to this feature).
- Every workflow needs an input dataset, so there is also a block to save the output from one workflow to use in another.
- A full description of all the OUTPUT blocks is given in this article.
Not all blocks work together. If two blocks refuse to connect, you are probably trying to connect two blocks that are incompatible.
