Open a GeoTIFF file in a GIS viewer. If you want the original lab scale that was set up in MicroStation, the scale from the Conform to the Datum should be 10:1. To place the currently displayed conform to the zoning document, set up the Conform coordinates and check out the ReSpacing tool of the Lat/Long Combination toolbox. The Conform should be placed at a 0,0,0 location. The Datum should be represented by the upper leftmost block of a geographical area. If any further information is needed, contact your local MicroStation expert. When a conform is set up, two new Lat/Lon blocks will be automatically added to the Datum section of the Datum/Conform. If you wish to alter the Datum of a conform you may manually place that conform to a new datum and use the ReSpacing tool to alter the new datum settings. One can make use of the Lat/Lon datum change feature by using the Change Conform and Datum tool from the toolbox. Use the Product coordinates of the Conform for the first coordinate of the Lat/Lon objects. The second coordinate is the coordinate of the Datum of the Conform.
Use the processing options from the CoProcessing Window (in the MicroStation preferences or by selecting the Analyze/Edit/CoProcessing options in the GUI), or by running the SeismicConversions tool (in Reprocessing). The SeismicConversions tool can be found in the Library tab, under the Processes folder, or by double-clicking on the SeismicConversions.exe file in the root directory of the Terrascan Tools folder.To run SeismicConversions right-click on the exe file and select Run As Adminstrator. When prompted, select all the files in the /Sdc/ folder.
