Remove YDYR - Analysis tools

Remove from YDYR from Analysis tools Add satellite imagery use case of delta/difference tool

[steve9164]

Since the satellite imagery items that support difference/delta already exist in the catalogue, and it's undefined behaviour to have 1 item twice in the catalogue, I think it'd be best to include the items by making a copy of them. This should be possible by using the terria catalogue reference with a path to the item, but give it a different id (probably best to give it a 8-10 character random id). Ensure that the id you choose is used for both the reference and the target model when loaded rather than the id defined by DEA (can check using React tools that reference.uniqueId and reference.target.uniqueId - after the item is loaded - are correct [ask @steve9164 for a demo of this if needed]).

@AnaBelgun and @steve9164 Please clarify if my understanding is correct. There are a few (8 items have availableDiffStyles properties.) satellite imagery items such as DEA Surface Reflectance (Landsat and Sentinel-2) that can use difference tool to performance analysis. We need to make copies of those items in the group of Analysis Tools so that a user can performance analysis like this.

• The first item. The json looks like this:

      {
        "name": "DEA Surface Reflectance (Landsat and Sentinel-2)",
        "url": "https://raw.githubusercontent.com/GeoscienceAustralia/dea-config/master/prod/terria/dea-maps-v8.json",
        "path": ["CqkxcG", "Wqpk8F"],
        "id": "a-copy-of-Wqpk8F",
        "type": "terria-reference"
      }  

  If you confirm it is expected, I will continue to add the rest.

• Do we need to provide step-by-step guide?

@mwu2018 hi, yes, that's the dataset I will write the step by step guide and put the content here

[steve9164]

@mwu2018 Perfect! Thanks.

[AnaBelgun]

@mwu2018 you can try to include this guide and video: https://userguide.terria.io/interactions-functionalities-and-workflows#change-detection-delta-workflow

[mwu2018]

@AnaBelgun If you are ok with this, I will copy it to test and prod.

[AnaBelgun]

hi @mwu2018 thank you. I've made some changes below:

Name of dataset in the catalogue - Change detection using DEA Surface Reflectance (Landsat and Sentinel-2) Description - This catalogue group will include examples of tools and workflows aimed at specific use cases. The first example is the "Change detection" workflow. It supports understanding variances in vegetation cover when using satellite imagery such as Landsat and Sentinel-2. Check this guide for more information.

[mwu2018]

@AnaBelgun Done. Please check and let me know if it is ok to copy to prod.

Once you approve the changes, I will merge this PR https://github.com/TerriaJS/saas-catalogs-public/pull/317

please do @mwu2018
