MapBox MBTiles Writer Feature Type Parameters
|
To access feature type parameters, click the gear icon Tip To always display the editor in FME Workbench, you can select View > Windows > Parameter Editor.
General All feature types share similar General parameters, which may include Feature Type Name, Reader or Writer information, and Geometry. In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept Table or Index Qualifier prefixes on the output table feature type. |

Interpolation Type
Determines the resampling algorithm used when constructing tile data:

Description |
|---|---|
|
Bilinear (default) |
Calculates a pixel's value by averaging the closest 2x2 neighborhood of pixel values. This method produces a higher-quality result than Nearest Neighbor. |
|
Nearest-neighbor |
Nearest-neighbor interpolation uses the value of the nearest pixel to calculate the value of a given pixel without considering the values of pixels outside this nearest pixel range. Nearest-neighbor is the least resource-intensive, but also produces the lowest-resolution tiles. |
|
Cubic |
Calculates a pixel's value by using the closest 4x4 neighborhood of pixel values. |
|
Cubic-spline |
Because it calculates a pixel's value by using a spline, this results in a smaller error than linear interpolation, and the interpolation is smoother. |
|
Lanczos |
Use Lanczos interpolation when you want to enhance or maintain local contrast; it is useful for viewing detailed features or boundaries. |
|
Mode |
This is a custom resampling algorithm made by GDAL. This method will select the value which appears most often in all the sampled pixels and use that as the value for the given pixel. |
|
Average |
This is a custom resampling algorithm made by GDAL. This method will use the average of all non-NODATA contributing pixels to compute the value of a pixel. |
