Select Feet or Meters FIRST, then you will be presented with a list of available systems in the “Known Coordinate System” field.
PIX4DMAPPER GROUND CONTROL POINTS PLUS
Next, set your Output Coordinate System from the Project Menu:Ħ. The output coordinate system, plus the units setting, must match those set (or about to be set) in IMS Map360. This coordinate system may differ from your Ground Control File coordinate and unit Settings or your Output coordinate and unit Settings without adversely affecting your results.ĥ. It is dependent on your drone or camera settings. Note the Image Coordinate System shown above, this is the system by which geotags are interpreted. Evidence Recorder can also be used to measure points and linework for other details that you need to include in your map but are concerned will not be visible from the photographs. Evidence Recorder and an RTK GPS system can be used to collect Ground control points that match painted targets that were included in the photographs. A UAV and Terrestrial Cameras can be used to create imagery. Importing a New Coordinate System in Pix4Dġ. Perform fieldwork to collect imagery and, if required, ground control points on visible ground targets. Setting the Output Coordinate System in Pix4D Once you have selected a system you will probably continue to use the same one as long as you are working in the same region. Refer to your local surveying authority or use this map to determine which coordinate systems are valid for your geographical region.Setting the Project Coordinate System in IMS Map360.
Setting the Export Coordinate System in Pix4D.Collecting Ground Control Points and any additional points and linework when using Evidence Recorder and a GPS Receiver (IF you are exercising this additional option).The coordinate system and units must be the same during the following three stages of the process:.This coordinate system can differ from the Export and Project Coordinate Systems. Your UAV may require you to select a coordinate system to be used for Geotagging.
This guide will step you through the process. The user must select appropriate settings with regards to Units (Feet, US Feet, or Meters) and the Mapping Coordinate system. Important Note: Pix4D, IMS Map360 and Evidence Recorder can collect data which can be merged into a single Map360 project.
