Overview
KML (Keyhole Markup Language) files are used to import parcel boundaries and area data drawn in Google Earth into PVX.AI. This guide explains how to import your Google Earth data into your PVX.AI project, including satellite imagery and elevation data.
Prerequisites
PVX.AI must be active, and you need a KML file prepared in Google Earth.
Step-by-Step Guide
1. Activate PVX.AI
Click the Switch On button on the PVX.AI ribbon in AutoCAD.
2. Import the KML file
Click Import Google Earth on the ribbon and select your KML file. You can choose boundaries, roads, or exclusion areas from the file.
3. Verify polygon closure
Make sure the imported polygons are closed. If the Close section shows ‘open’, change it to Yes to make it usable in PVX.AI.
4. Check the coordinate reference system
Verify that the CRS (Coordinate Reference System) and units are correct. Google Earth data typically uses the WGS84 coordinate system.
5. Load satellite imagery and elevation data
Click Image Elevation and select your parcel boundary. Activate the image with Load Image and enter the mesh spacing for the triangle models (between 0.5 m and 30 m). PVX.AI will import the satellite image, slope table, and 3D surface model into your project.
Tips & Recommendations
- Make sure your polygon is fully closed when drawing parcel boundaries in Google Earth.
- Use smaller mesh spacing (0.5-2 m) for small sites; 5-15 m is sufficient for large sites.
- If your KML file contains multiple layers, you can selectively import the ones you need.
