When a tree record is saved, if MobileMap finds offset coordinates, distance and azimuth and appropriate fields for storing tree coordinates, it will attempt to calculate and store the tree coordinates. If the Trees layer is a Point layer (rather than the typical non-spatial attribute table) it will also save the geometry for the record. These calculations do not happen when the
Some laser rangefinders (e.g., Haglof Vertex Laser Geo) can connect directly to a sub-meter GPS and calculate the target tree coordinates directly. When using these devices, MobileMap can receive and store the tree coordinates at the same time as the tree height information.

*Offset X/Y is captured from the MobileMap Android device via the onboard GPS antennae or a Bluetooth connected GPS (e.g., Juniper Geode or EOS Arrow 100). It does not come from the laser rangefinder itself, but the capture is triggered when laser rangefinder data are received, so the coordinates stored are the GPS coordinates at the time of laser data capture. It is essential that the GPS antenna be co-located with the laser rangefinder (not at plot center!) for these data to be useful.

Configure laser range finder tree-level settings found in Settings > MobileMap Cruise > Trees. Make sure to enter exact field names (not aliases) for all tree attribute fields that you intend to populate via the laser rangefinder. Available settings:
Setting | Purpose |
|---|---|
Tree Height 1 Field | Used to store incoming height data, in units selected on the laser rangefinder. Typically used to record total tree height, but if 2 heights are collected for each tree (e.g., merch height and total height) this should be set to the lower height to enable collection of tree from bottom to top. |
Tree Height 2 Field | Same as above, but if 2 heights are collected for each tree (e.g., merch height and total height) this should be set to the higher height to enable collection of tree from bottom to top. |
Tree Distance Field | Can be used to store incoming distance data, in units selected on the laser rangefinder. Typically used to record the distance of a tree from plot center or from a GPS measurement. |
Tree Azimuth Field | Can be used to store incoming azimuth data, in degrees. Typically used to record the azimuth of a tree from plot center or from a GPS measurement. |
Tree Longitude Field | Can be used to store the Latitude value for the target tree. Only possible when laser rangefinder includes an integrated or connected GPS and supports onboard calculation of target tree coordinates based on GPS location, distance and azimuth. |
Tree Latitude Field | Can be used to store the Latitude value for the target tree. Only possible when laser rangefinder includes an integrated or connected GPS and supports onboard calculation of target tree coordinates based on GPS location, distance and azimuth. |
Tree Offset Longitude Field | Can be used to store the Longitude value from the MobileMap device at time of laser rangefinder data capture. Typically used with Bluetooth sub-meter GPS connected directly to the MobileMap device. Used in post-processing to calculate the coordinates of the target tree. |
Tree Offset Latitude Field | Can be used to store the Latitude value from the MobileMap device at time of laser rangefinder data capture. Typically used with Bluetooth sub-meter GPS connected directly to the MobileMap device. Used in post-processing to calculate the coordinates of the target tree. |
