Feature Type(s) to Read
Click the browse button to select feature types from the list. If no feature types are specified, then all available feature types will be read.
Spatial Filter
Worldwide Reference System
Landsat data is identified by path and row numbers of the Worldwide Reference System (WRS). The combination of a path and row number uniquely identifies a nominal scene center.
For more information, see:
Envelope
Using the minimum and maximum latitude and longitude parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.
If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.
Coordinates must be in LL84.
Date Filter
Date Filter
- Latest (default) – Get the latest imagery for only the selected grid squares.
- All – Get all available imagery for the selected grid squares.
- Date Range – Type the start and end dates, or select them from the displayed calendars.
- Selected Dates – A date is displayed if one or more of the selected grid squares are available on that date. Selecting a date will download all grid squares inside the selection which are available on the selected date.
Quality Filter
Quality Filter
Maximum Percentage Cloud Cover: The maximum percentage of the image that may contain cloud cover. Images with more cloud cover than this threshold are skipped.
Minimum Data Quality Assessment: Data quality is assessed using the values 0 to 9, where 0 is the worst quality and 9 is the best quality. Images with less usable data than this threshold are skipped.
Advanced
Verify HTTPS Certificate
Prior to FME 2022.0, web access through this format would automatically disable HTTPS Certificate verification when an SSL Error was received from the server. Now, this behavior must be explicitly enabled or disabled by this parameter.
The value of this parameter takes priority over the value of the Verify SSL Certificates parameter which might be defined by the Web Connection used with this format.
Schema Attributes
Additional Attributes to Expose
Use this parameter to expose Format Attributes in FME Workbench when you create a workspace:
- In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
- In a non-dynamic scenario, this parameter allows you to expose additional attributes on multiple feature types. Click the browse button to view the available format attributes (which are different for each format) for the reader.
