Processing image dataMap AreaTop ToolbarProjectSummaryLocalProcessingpanelLayersStep 1: select 1. Initial Processing,Rapid Check Step 2: click ‘Start’Automatic Reconstruction Report generationTo create a Quality Report while in the field bring up the local processing panel byselecting ‘Local processing’ from the ‘Process’ menu or by clicking the icon inthe Toolbar. Select only the ‘Initial project processing’ checkbox and the ‘Rapid’button. If you wish to create a low-resolution orthomosaic while generating thereport, check the ‘Orthomosaic and DSM generation’ checkbox. Click ‘Start’ tobegin rapid processing.Postflight Terra 3D will now process the data and produce a report that includesthe overall completeness and georeference quality of the images taken duringyour last mission. You may use this information to decide whether further imag-ing flights are required while you are still in the field. The quality report will bedisplayed in a new window (click the icon in the Toolbar if it does not appear).53
Quick start guide3.3 Creating advanced mapping productsBeyond Quality Reports and low-resolution orthomosaics, Postflight Terra 3D cangenerate geo-referenced high-resolution 2D orthomosaics, 3D point clouds, tri-angle models and DSMs or export to common third-party photogrammetry soft-ware such as Bingo, Orima or Inpho. Ground Control Points (GCP) can be added toincrease the geo-reference accuracy. Postflight Terra 3D also includes a mosaic anda rayCloud editor, giving you more control on the quality of your final mappingproducts, as well as measurement tools.The resulting orthomosaic and DSM may then be imported as custom backgroundmap and elevation data layers in eMotion¹⁷. This data can be used for advancedflight planning in complex or uneven terrain.Note: You need to either enable tile set generation OR choose Gen-erate Google Maps Tiles and KML from the Process menu before youcan push the tileset into eMotion by choosing Send Map to eMotionfrom the Process menu. Alternatively, this data can be imported intoeMotion; choose Import custom map from eMotion’s File menu.Note: The best way to learn how to use the various features of Post-flight Terra 3D is to look at the comprehensive online Knowledge Basewithin my.senseFly¹⁸¹⁷ see the eBee Extended User Manual for more information on importing layers into eMotion54

Processing image dataGlossaryAMSL Above Mean Sea LevelYour eBee’s altitude can be shown and set in eMotion using ATO or AMSL.Your drone uses the EGM96 mean sea level standard for navigation.ATO Above the Take-off AltitudeYour eBee’s altitude can be shown and set in eMotion using ATO or AMSL.Altitudes in ATO are relative to the place your eBee started its motor justbefore take-off.DSM Digital Surface ModelA 3D digital representation of a surface.FTDI Future Technology Devices InternationalA Scottish semiconductor device company specialising in Universal SerialBus (USB) technology. FTDI cables allow serial connections through a USBcable. eMotion uses FTDI technology to connect to the ground modem.You can often connect a computer to a GNSS base station using FTDI.geo-reference A data point associated with a specific location on the earth’s sur-face.GSD Ground Sampling DistanceThe distance measured on the ground between pixel centres in an imageor DSM. The smaller the GSD, the higher the spatial resolution of the image.For example, a GSD of 5 cm means that one pixel in the image represents5 cm on the ground.mosaic A single map or terrain model created from several map sections thathave been placed side-by-side and merged together.orthomosaic A single, corrected image constructed either from several imagestaken from different angles, or from several orthophotos. Distortions due59
Specificationsto different camera positions, ground curvature and relief are corrected forso that the image displays accurately in the given map projection.photogrammetry A technique in which measurements taken from photographsare used to reconstruct a 3D surface or a series of points in space.point cloud A set of data points within a coordinate system.rayCloud A feature unique to Postflight Terra3D that combines the 3D point cloudwith the original images. Multi ray matching with the rayCloud extends thestereo view triangulation and increases the accuracy of 3D point estimateswhile providing a full understanding of 3D results.triangle model An approximate representation of a surface, constructed fromconnected triangles.60
