Curatorial interns at the UC Davis Arboretum and Public GardenÂ use mapping grade GPS and a laser rangefinder to inventory the Ruth Risdon Storer Garden.
Choosing the right equipment for your GIS project can be a difficult task when faced with the wide variety of vendors and configurations available. Â We have attempted to simplify this task by describing a few of our favorite configurations.
Mapping Grade GPS
Using mapping grade GPS is the most common way that public gardens collect accurate position and attribute information in the garden. Â You may choose from an package system that integrates a GPS receiver, handheld computer, and laser rangefinder or individual components. Â Both options require a software solution.

If you have an accurate basemap for your public garden already, you may not need the complexity of a mapping grade GPS system to collect position and attribute information in the garden. Â Heads-up digitizing allows you to use the built-in GPS device on your smartphone or tablet to locate your position in the garden and then choose the location of the feature you wish to collect information on based on its position relative to features in your basemap such as planting beds and pathways. Â New advances in GPS technology now allow for a mapping grade GPS receiver to be connected to your smartphone or tablet via Bluetooth wireless technology. Â Consider adding one of these devices for the ultimate combination of simplicity and accuracy. Â Although this technique may be implemented using any iOS or Android device, we have provided recommendations for our favorite hardware.
