Presentation and options

This program allows the following transformations between Surfer formats and the formats of MiraMon:

Import grids: given a Surfer grid file (GRD), it is possible to generate the corresponding MiraMon raster file (IMG) with its metadata file (I.REL), based on the information in the GRD header. The Surfer grid should be in ASCII format (care should be taken when exporting from Surfer) and the resulting IMG is always real format. Although MiraMon raster format requires the same resolution in both dimensions and, therefore, a square pixel size, the program allows importing Surfer grids with non-square pixel sides. In this case a bilinear geometric correction is performed to resample the original data to a net of equally spaced square pixels with the side equal to the smaller of the two dimensions of the original.

Export rasters: allows exporting any uncompressed MiraMon raster format to the Surfer grid format. When the input raster file is a compressed (RLE) file, it is necessary to use the IMGIMG application to uncompress it. It is also possible to apply a multiplication factor to the raster values when writing the corresponding 'Z' coordinates to the GRD format file.

Export point files: unstructured point 2D or 3D vector files (VEC) can be exported to Surfer data (DAT) format. The attribute of the VEC file must be numerical. Files in the corresponding Surfer format (DAT) can be imported using the BDPNT application which will produce a structured point file (PNT).
