If I understand correctly you would like some guidance seeing an image within an imported KML polygon area.

To view high-resolution imagery within a KML-defined area on the Planet platform, follow these steps: 

1. Import Your KML as Area of Interest (AOI):

   • In Planet Explorer, you can upload a KML file to define your AOI. Use the search bar or the upload option to add your KML, and the platform will display available imagery for that area. This works for other supported formats as well (Shapefile, GeoJSON, WKT) Searching for Imagery in Planet Explorer.

2. Search and Preview High-Resolution Imagery:

   • After importing your KML, use the search and filter tools to find high-resolution imagery (e.g., SkySat for 0.5m, PlanetScope for ~3m). You can preview imagery before ordering to ensure it covers your AOI and meets your resolution needs Search and Preview Imagery.

3. Order and Download Full-Resolution Imagery:

   • Once you identify suitable imagery, place an order. The downloaded files (such as GeoTIFFs) will be in full spatial resolution and can be clipped to your AOI polygon Order Imagery - QGIS Plugin.

4. Viewing in GIS or Google Earth Pro:

   • If you want to visualize the imagery in Google Earth Pro, you can overlay the downloaded GeoTIFFs. Use the "Create Super Overlay" option in Google Earth Pro to view the imagery at full resolution within your KML area Using Planet GeoTIFFs in Google Earth Pro.
