  12. def convert(targetCellType: TargetCellType): RasterSource

    Converts the contents of the GDALRasterSource to the TargetCellType.

    Converts the contents of the GDALRasterSource to the TargetCellType.

    Note:

    GDAL handles Byte data differently than GeoTrellis. Unlike GeoTrellis, GDAL treats all Byte data as Unsigned Bytes. Thus, the output from converting to a Signed Byte CellType can result in unexpected results. When given values to convert to Byte, GDAL takes the following steps:

    1. Checks to see if the values falls in [0, 255]. 2. If the value falls outside of that range, it'll clamp it so that it falls within it. For example: -1 would become 0 and 275 would turn into 255. 3. If the value falls within that range and is a floating point, then GDAL will round it up. For example: 122.492 would become 122 and 64.1 would become 64.

    Thus, it is recommended that one avoids converting to Byte without first ensuring that no data will be lost.

    Note:

    It is not currently possible to convert to the BitCellType using GDAL.

    All the information received from the JNI side should be cached on the JVM side, to minimize JNI calls.

    All the information received from the JNI side should be cached on the JVM side, to minimize JNI calls. Too aggressive JNI functions usage can lead to a significant performance regression as the result of the often memory copy.

    For the each JNI call the proxy function will send arguments into the C bindings, on the C side the result would be computed and sent to the JVM side (memory copy happened two times).

    Since it would happen for each call, much safer and faster would be to remember once computed value in a JVM memory and interact only with it: it will allow to minimize JNI calls, speed up function calls and will allow to memoize some potentially sensitive data.
