Comprehensive Guide: Exporting Data from DroneDeploy to Revit via ReCap
Introduction
DroneDeploy employs photogrammetry to produce 3D point cloud (LAS) data, which can be exported and utilised in various design software. This guide details the essential steps involved in exporting point cloud data, and importing it into ReCap, and subsequently integrating it into Revit or any other design software.
Coordinate System Used in DroneDeploy
DroneDeploy predominantly employs the WGS84 EPSG 3857 (Web Mercator) coordinate system for its 3D models and maps. However, other coordinate systems can also be utilised based on user preferences or project requirements.
Exporting Data from DroneDeploy
-
Navigate to the export feature located at the bottom left corner of the DD interface.
-
Select "Point Cloud" as the export format.
-
Ensure the desired target coordinate system is selected. It's advisable to use a local EPSG system for accuracy.
- Initiate the export process, and you will receive an email notification once the *.las file is ready for download.
Importing a *.las File into ReCap
ReCap facilitates the modification of point cloud data, enabling users to remove unwanted elements and reproject coordinates into different target systems. Follow these steps:
- Create a new project in ReCap and specify the import of a point cloud.
- Drag and drop the exported *.las file into ReCap.
-
Access advanced settings
- Ensure both current and target coordinate systems match the EPSG used in the DD export.
- Import the files, resulting in the creation of a *.rcp file compatible with Revit.
Importing a *.rcp File into Revit
- Launch Revit and initiate a new project.
- Select "Insert," then "Point Cloud."
-
Navigate to the location where the *.rcp file is stored and import it into Revit.
Comparing Measurements
- Ensure that the coordinate systems used in ReCap and DD for export are consistent to maintain accurate dimensions.
- For further understanding of EPSG and coordinate systems, refer to the Wiki link and EPSG tool.
By following these steps, you'll be able to transfer point cloud data from DroneDeploy to Revit via ReCap, enabling efficient integration into design workflows.
