GeoCue’s repository of TrueView tools, tips and workflows for the TrueView line of drone mapping products. Includes former AirGon products such as Loki and ASPSuite.
When dealing with Polyline or Polygon features in LP360, vertices are color coded based on their place in the beginning or end of the created feature in relation to their drawn direction. This article provides an explanation for what these colors represent. Color Description Red/green vertex color is the start/end of the line on the…
If your organization has strict security settings, some of the executables installed and used by LP360 or True View EVO could get blocked and prevent LP360/EVO from operating correctly. It may be necessary to get your IT department to add these executables to an approved list. The following instructions will show you how to find…
Multipart features are not supported for the Feature Edit tools in LP360 standalone and may result in an error message such as, “…Complex polygons is not supported”. The polygon must be a single part feature. This can be verified in the Feature Analyst dialog: You will need to first Disassemble Multipart Feature, then run the Split Geometry,…
Contours can be generated from a TIN surface at specified intervals. The contours are saved to one of the three following file formats: shapefiles, DXF, or DGN. Contours are stored as 3D polylines for DXF and DGN file formats. You have a choice to save polylines as 3D or 2D when exporting to shapefiles, where…
When the auto-download of the ephemeris and alternate navigation is not working you may elect to manually determine the an alternate navigation file to download from the NASA CDDIS site while your IT resolves any connection issues. Click here to determine the ephemeris file to download from NASA’s CDDIS. Determine the start/end times in UTC…
When the auto-download of the ephemeris is not working you may elect to manually determine the correct ephemeris file to download from the NASA CDDIS site while your IT resolves any connection issues. Click here to determine the alternate navigation file to download from NASA’s CDDIS. Determine the start/end times in UTC or GPS for…
When using a True View 3D imaging system, what check point recommendations do you have? Check points should always be used to validate the absolute positional accuracy of imaging and 3D imaging projects. We follow the ASPRS Digital Accuracy Standards, Annex C. Its an older standard than most UAV mapping so you’ll find that it’s…
This post applies if your grid to ground conversion requires needing to apply a horizontal rotation about an origin point and is defined by: Horizontal Translation North (tN) Horizontal Translation East (tE) Horizontal Rotation (Rz) Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Then, if the horizontal scale factor is one, luckily,…
OPUS is an online GNSS static data post-processing service. NOAA’s Online Positioning User Service (OPUS) provides free access to high-accuracy National Spatial Reference System (NSRS) coordinates. This service is occasionally unavailable so the following links can be used to post-process your static GNSS observation. CSRS-PPP Canadian Spatial Reference System (CSRS) Precise Point Positioning (PPP) is a service…
This post applies if your grid to ground conversion requires applying a horizontal scale about an origin point and is defined by: Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Scale based grid to ground transformations are probably the most common. If the origin point is not defined, it is usually implied…
