Enumeration Type Documentation

enum mifi_interpol_method

interpolation method

Flag for nearest neighbor interpolation. This requires, that the original data comes with a properly defined projection, i.e. implicit as latlon or explicit with projection-string

Enumerator
MIFI_INTERPOL_UNKNOWN	Error-flag for unknown interpolation-method
MIFI_INTERPOL_NEAREST_NEIGHBOR	Flag for bilinear interpolation. This requires, that the original data comes with a properly defined projection, i.e. implicit as latlon or explicit with projection-string
MIFI_INTERPOL_BILINEAR	Flag for bicubic interpolation. This requires, that the original data comes with a properly defined projection, i.e. implicit as latlon or explicit with projection-string
MIFI_INTERPOL_BICUBIC	Flag for bicubic interpolation. This requires, that the original data comes with a properly defined projection, i.e. implicit as latlon or explicit with projection-string
MIFI_INTERPOL_COORD_NN	Flag for nearest neighbor interpolation using lon/lat coordinates rather than the input projection. This is largely a brute force method which may take long time. Vector projection is not implemented (not defined?) Warning this works only from CDMInterpolator
MIFI_INTERPOL_COORD_NN_KD	Flag for nearest neighbor interpolation using coordinates with KD-tree. This works as nearest neighbor in the output-projection and has therefore numerical problems in some points, i.e. near southpole when using northpole-polarstereographic. It doesn't work with output projections in degree, i.e. rotated latitude longitude, since distances are calculated as outX^2*outY^2 Vector projection is not implemented (not defined?) Warning this works only from CDMInterpolator
MIFI_INTERPOL_FORWARD_SUM	forward interpolation, summing over all matching input-cells
MIFI_INTERPOL_FORWARD_MEAN	forward interpolation, averaging (mean) over all matching defined input-cells
MIFI_INTERPOL_FORWARD_MEDIAN	forward interpolation, median over all matching defined input-cells
MIFI_INTERPOL_FORWARD_MAX	forward interpolation, max over all matching defined input-cells
MIFI_INTERPOL_FORWARD_MIN	forward interpolation, min over all matching defined input-cells
MIFI_INTERPOL_FORWARD_UNDEF_SUM	forward interpolation, summing over all input-cells, thus propagating undefined values, i.e. value+undef=undef
MIFI_INTERPOL_FORWARD_UNDEF_MEAN	forward interpolation, averaging (mean) over all input-cells, thus propagating undefined values, i.e. value+undef=undef
MIFI_INTERPOL_FORWARD_UNDEF_MEDIAN	forward interpolation, median over all input-cells, thus propagating undefined values, i.e. value+undef=undef
MIFI_INTERPOL_FORWARD_UNDEF_MAX	forward interpolation, max over all input-cells, thus propagating undefined values, i.e. value+undef=undef
MIFI_INTERPOL_FORWARD_UNDEF_MIN	forward interpolation, min over all input-cells, thus propagating undefined values, i.e. value+undef=undef
