Label | Explanation | Data Type |
Mosaic Dataset | The mosaic dataset that contains the raster datasets whose footprints you want to compute. | Mosaic Layer |
Query Definition (Optional) | An SQL expression to select specific raster datasets within the mosaic dataset. | SQL Expression |
Computation Method (Optional) | Refine the footprints using one of the following methods:
| Boolean; String |
Minimum Data Value (Optional) | Exclude pixels with a value less than this number. | Double |
Maximum Data Value (Optional) | Exclude pixels with a value greater than this number. | Double |
Approximate number of vertices (Optional) | Choose between 4 and 10,000. More vertices will improve accuracy but can extend processing time. A value of -1 will calculate all vertices. More vertices will increase accuracy but also the processing time. | Long |
Shrink distance (Optional) | Clip the footprint by this distance. This can eliminate artifacts from using lossy compression, which causes the edges of the image to overlap into NoData areas. Shrinking of the polygon is used to counteract effects of lossy compression, which causes edges of the image to overlap into NoData areas. | Double |
Maintain sheet edges (Optional) | Alter the footprints of raster datasets that have been tiled and are adjacent (line up along the seams with little to no overlap).
| Boolean |
Skip overviews (Optional) | Adjust the footprints of overviews.
| Boolean |
Update Boundary (Optional) | Update the boundary of the mosaic dataset if you have added or removed imagery that changes the extent.
| Boolean |
Request Size (Optional) | Set the resampled extent (in columns and rows) for the raster when building footprints. Greater image resolution provides more detail in the raster dataset but increases the processing time. A value of -1 will compute the footprint at the original resolution. | Long |
Minimum Region Size (Optional) | Avoid small holes in your imagery when using pixel values to create a mask. For example, your imagery may have a range of values from 0 to 255, and to mask clouds, you've excluded values from 245 to 255, which may cause other, noncloud pixels to be masked as well. If those areas are smaller than the number of pixels specified here, they will not be masked out. | Long |
Simplification Method
(Optional) | Reduce the number of vertices in the footprint to improve performance.
| String |
Edge tolerance (Optional) | Snap the footprint to the sheet edge if it is within this tolerance. Units are the same as those in the mosaic dataset coordinate system. By default, the value is empty for which the tolerance is computed based on the pixel size corresponding to the requested resampled raster. A value of -1 will compute the tolerance using the average pixel size of the mosaic dataset. | Double |
Maximum Sliver Size
(Optional) | Identify all polygons that are smaller than the square of this value. The value is specified in pixels and is based on the Request Size, not the spatial resolution of the source raster. Regions less than the (Maximum Sliver Size)^2 and less than the Minimum Thinness Ratio are considered slivers and will be removed. | Long |
Minimum Thinness Ratio (Optional) | Define the thinness of slivers on a scale from 0 to 1.0, where 1.0 represents a circle and 0.0 represents a polygon that approaches a straight line. Polygons that are below both the Maximum Sliver Size and Minimum Thinness Ratio will be removed from the footprint. | Double |
