TerraPhoto is commonly used for creating a seamless, positionally accurate orthophoto mosaic as the final product. Many steps in the TerraPhoto workflow prepare a data set for this aim. The rectification itself is an automatic process.
This chapter describes typical settings that you would use for producing orthophotos of two different quality levels. “Quick” orthophotos may be produced for internal purposes only. “Final” orthophotos are the actual end product that is delivered to the customer. These two levels of orthophotos are produced by selecting different parameters for the rectification process.
The creation of an orthophoto mosaic requires tiles which represent the orthophoto boundaries. Tiles can be produced by Place tile array command or Place Tile Array tool in TerraPhoto, or by any MicroStation tool that produces rectangular shapes. The rectification is started by the Rectify mosaic command from the Rectify pulldown menu in TPhoto Main window.
