Vexcel Osprey
This page describes the original Vexcel Ultracam Osprey oblique mapping resources for Orbit import.
Use the corresponding Orbit Import Template to import the described original data.
It is recommend to read first Orbit Mapping Resource.
Imagery
Today the Ultracam Osprey Camera 1 should not be imported, skip the import step and continue from Camera 2.
Image files
Files : *.tif files, each oblique image is one tif image file.
Naming : Exactly as the result of “Concat([Nr],[Filename_Suffix])”, from the photoposition file bellow.
Image positions and orientations files
File : one *.csv or *.txt file for each camera
Structure : Flat ascii text file
Rows : each image is one record
Columns : semicolumn separated (char59), headers, with exact order as the example below.
Structure of file name : Exactly as the result of “Concat([Nr],[Filename_Suffix])” from the example bellow.
