Accessing details fails for OPERA Coregistered Single-Look Complex results

[tylere]

To reproduce:

1. In browser, open https://discover.maap-project.org/
2. In the text search box, enter "OPERA Coregistered Single-Look Complex"
3. Click the Search button
4. In the search results (example: "OPERA Coregistered Single-Look Complex from Sentinel-1 validated product (Version 1)") click on the "Details" button.
5. The result is a blank page.

The Chrome console reports the following error:

react-dom.production.min.js:188 TypeError: e is not iterable
at ResultsTable.tsx:54:49
at Array.map ()

This is the frontend crashing when the spatial_extents field in the JSON is [ null ] which is happening because the CMR collection record does not have the boxes property.

The amplitude is primarily determined by ground surface properties (e.g., terrain slope, surface roughness, and physical properties), and phase primarily represents the distance between the radar and ground targets corrected for the geometrical distance between the two based on the knowledge from Digital Elevation Model and platform’s position, i.e., the CSLC phase represents residual geometrical distance between the sensor and target, the atmospheric propagation delay and the target movements. The CSLC-S1 product is derived from Copernicus Sentinel-1A and Sentinel-1B Interferometric Wide (IW) SLC data.  \n\nThe CSLC images are precisely aligned or “coregistered” to a pre-defined UTM/Polar stereographic map projection systems and posted at 5x10 m spacing in east and north direction, respectively.  Each CSLC-S1 product corresponds to a single S1 burst and is distributed as a Hierarchical Data Format version 5 (HDF5) file following the CF-1.8 convention containing both data raster layers (e.g., geocoded complex backscatter, low-resolution correction look-up tables) and product metadata.

Instead of boxes it has polygons which probably contain some kind of spatial extent information.

The CMR STAC record for one of these collections has a spatial extent:

These static layers are provided separately from the OPERA CSLC-S1 product, as they are produced only once or a limited number of times, to account for changes in the DEM, in the S1 orbit, or in the static layers generation algorithm. Each OPERA CSLC-S1-STATIC product is distributed as a Hierarchical Data Format version 5 (HDF5) file following the CF-1.8 convention containing both data raster layers and product metadata and corresponds to matching CSLC-S1 products with the same burst ID. OPERA CSLC-S1 products are available over North America which includes the USA and U.S. Territories, Canada within 200 km of the U.S. border, and all mainland countries from the southern U.S. border down to and including Panama. The CSLC-S1 products are available in the associated OPERA Coregistered Single-Look Complex from Sentinel-1 validated product (Version 1) dataset.",

In the short term there are a few options:

• check to see if the polygons field can be used to generate spatial extent info and use it if boxes is not populated:
  

  federated-collection-discovery/src/server/federated_collection_discovery/cmr_collection_search.py

  Lines 83 to 86 in 4f26297

  	bbox_parsed = None
  	if boxes:
  	bbox_split = [float(i) for i in boxes[0].split(" ")]
  	bbox_parsed = (bbox_split[1], bbox_split[0], bbox_split[3], bbox_split[2])

• skip the map in the collection details page if spatial_extent is empty

In the longer term this makes me want to drop support for CMR and ping the CMR STAC APIs instead 😛
