Background and strategic fit
With S1TBX, this is a problem for high res TerraSAR-X data. In particular when running the SAR Simulation it produces a number of artifacts in the image.

1 | Tie point interpolation | Part of the problem is caused by the unit (lat lon in degrees, slant range time in seconds) but this should probably stay as is. At high resolutions (< 1m), neighbouring pixels end up having the same value. Tie Point Grids and DEMs need to be interpolated to the resolution of the data product. Interpolators have already been made 64-bit. Now the resulting value needs to be saved as 64-bit.

2 | Tie point writing/reading | When writing tie point grids a datatype field specifies if it is Float32 or Float64 When reading, the reader should use this field to first determine the type and then read the data accordingly |
