Prepare TerraSolid Data

This page describes the original TerraSolid TerraPhoto mobile mapping resources for Orbit import.

Use the corresponding Orbit Import Template to import the described original data.
It is recommend to read first Concepts of Mobile Mapping and UAS data in Orbit.

• Image type : Ladybug 5, equirectangular panoramas.
• Image resolution : Ratio 2×1, advised 8000×4000 pixels.
• File format : Each image is one *.jpg file.
• File name : Exactly as “Image” value of image positions file, see below.
• Folder structure : All files in one folder.

• File format : One ascii *.csv file.
• File structure Rows : Each image is one record.
• File structure Columns : Comma separated (char44), headers, with exact order as the example below.
• Value of Image : Filename as on disk with file extension, see below.
• Value of Coordinates : any supported coordinate system can be used, Long/Lat order for geographical coordinates, decimal notation, without thousands separator.
• Value of Timestamps : GPS Absolute time or GPS Week time, decimal notation.
