Import geometries - PIX4Dmatic

PIX4Dmatic allows importing geometries into an existing project. This feature can be useful in many contexts when it is necessary to add additional information to our project. These geometries could be any 3D element that represents reality.

How to import a geometry file

The coordinate reference system of the project must be defined before importing a geometry file into a project. Once the project is created and has a reference coordinate reference system, then follow these instructions:

  1. Open a project in PIX4Dmatic.
  2. File > Import > Geometries...
  3. Select the file (All point files or All vector files).
  4. Click Open.

Import point files

Supported file formats for importing points as geometries include CSV files(*.csv), XYZ files (*.xyz), and Text files (*.txt). After importing the file, it is necessary to specify its coordinate reference system (CRS):

 

  • Horizontal coordinate reference system: Defines the exact position of the objects in 2D.
  • Vertical coordinate reference system: Defines the origin for height or depth values. For more information: How to use vertical coordinate systems and geoids - PIX4Dsurvey.
    • Geoid: Refers to the local geoid model that covers the territory.
    • Geoid height: Indicates the constant height over the Bessel 1841 ellipsoid that is used as a replacement for the geoid model.
  • Column separator: This field defines the character used to separate different columns. Values are comma (,), semicolon (;), space ( ), or tab ( ).
  • Decimal separator: This field defines the character used to define the decimals in a numeric value. Values are period (.) or comma (,).
  • Skipped row: it is used to specify at which line to start reading values from the file. This option can be used if the field loses focus on the table.
  • Column format: It is the format for reading the point locations in a file.
    • PNEZD: Point#, Northing, Easting, Elevation, Description.
    • PENZD: Point#, Easting, Northing, Elevation, Description.
    • PXYZD: Point#, coordinate X, coordinate Y, coordinate Z, Description.
    • PYXZD: Point#, coordinate Y, coordinate X, coordinate Z, Description.
    • PENZ: Point#, Easting, Northing, Elevation
    • PNEZ: Point#, Northing, Easting, Elevation.
    • PXYZ: Point#, coordinate X, coordinate Y, coordinate Z, Description.
    • PYXZ: Point#, coordinate Y, coordinate X, coordinate Z, Description.
    • ENZ: Easting, Northing, Elevation.
    • NEZ: Northing, Easting, Elevation.
    • XYZ: Latitude, Longitude, Elevation.
    • YXZ: Longitude, Latitude, Elevation.
    • Custom: Indicates that the format field is entered manually.
      • Horizontal accuracy: Refers to the precision with which the X/Y or easting/northing values were captured.
      • Vertical accuracy: Refers to the precision with which the elevation values were captured.
