The gCADPlus menu contains an option to import external data in the form of GPS coordinate and text data. Options available include import from a CSV file and import from Garmin GPX files.

GPS in

This option takes data in a standard comma separated file and based on information contained in the file puts a point marker entity at each location. The import tool provides a dialog box that is used to determine which comma separated zone is used for the x, y and z value for the point entity. A text label can also be added to the point.
Tip: If the CSV file has a header row, the header value can be used as an aid for data selection.

It is possible to load a base survey map and overlay with data from a CSV file generated during a survey. Typically we might show a base map of a site with (say) a wetland and accompanying cadastral information on roads and allotments. We run the GIS tool, select the CSV file and the data is plotted on top of the base map.
In one application, we ran a custom version of the generic GPSin command, colouring trees according to health.

The standard GPSin command in gCADPlus will import the first four columns in the data set.
Record 1 in your file should show the header information, then the routine will import column A (numeric), Column B (text), Column C (x coordinate) and column D (y coordinate). The remaining columns are ignored. A point is plotted at the x,y position and text written in the current style nearby.

Import Garmin GPX

This option takes a standard Garmin GPX file and imports the data, putting a point marker at the location the GPS value was recorded.


Many landscape designers and horticulturists carry smartphones when they are inspecting a new site. Many have some type of GPS capability called by an App. Location data can be easily gathered and used to orient and help orient and create a base plan in CAD software before a visit. It enables an users to capture the latitude and longitude at any desired location. Commonly  latitude, longitude, sample time, elevation etc. is available.
In this instance, tracking has been started and the Stop Tracking option is about to be selected.
Switching the view to ‘Map’ shows the location superimposed over a Google Earth images. This image (and others showing the complete house block) can then be emailed from the phone to the designer’s home base email address while they are on site. Google KLM file information can also be exported from the smart phone application as an aid in registering Google Earth images and GPS data. The GPXtrack option takes a data file from the phone and will plot the points recorded by the phone.
