Reference Layer Importer

The Reference Layer Importer tool allows users to upload a Shapefile or CAD file to their TreePlotter™ application. Once uploaded they can view that data in TreePlotter alongside all their other data as an additional layer on the map.

Shapefile Reference Layer in TreePlotter

Access the Reference Layer Importer, if turned on in your application, by going to Hub-> Data Tools-> Reference Layer Importer.

Add a Reference Layer

To Add a Reference Layer to your application, first select the file you want to upload. Populate the remaining fields and then click Submit.

Shapefile: Make sure to either select all files within the shapefile or use a zipped file. Shapefiles can be in any coordinate system.

CAD: Enter the Coordinate system of the file in the EPSG box. Many CAD files will list the coordinate system on the side when looking at the “Sheet” view or click here to look up your code. Need to access your file to determine the Coordinate system but don’t have AutoCAD? Consider using a free, online viewer such as AutoDesk Viewer.

View a Reference Layer

Once imported, your reference layer will show up on the bottom of the Legend. Use the checkbox to toggle it on and off the map. Clicking the “Snap To” option makes the mouse cursor snap to the edges of the layer when adding trees or other features in TreePlotter. Click Delete to remove the layer from TreePlotter.

Additional Features & Troubleshooting

Colors & Labels

CAD files will automatically pull colors and labels associated with a feature. For shapefiles, users can use the attributes TP_COLOR and TP_LABEL to define the colors and labels of features. Add the columns to your shapefile with the corresponding RGB value or the text of the label you want.

File Size Limit

Files must be less than 100MB and have fewer than 5 million vertices. Layers with fewer vertices will load faster and have better performance in TreePlotter. 

Projections/Coordinate Reference System

All data must have a coordinate reference system, otherwise the tool has no way to know where the features belong on the map. However, it is not necessary to reproject the data into a particular coordinate reference system before uploading.

For shapefiles, the coordinate reference system is automatically detected as long as all the necessary files are selected during the import. For CAD files, the user will usually need to manually enter the appropriate EPSG code in TreePlotter. In some cases if the CAD files have the proper metadata this can be detected automatically but this isn’t typical of most of the files we’ve tested.
