User's guide to Ivent

Introduction

Ivent is an Windows Mobile application for handheld devices. It is used for field inventory of sample plot data. PlanStart is used for setting up a sample design, and export data to Ivent, and import it back and process the collected data.

The inventory of a sample plot includes the registration of tree and site characteristics. The application can retrieve data from peripheral devices (through Bluetooth or other radio), including a digital caliper (for tree diameter measurement), a clinometer (for tree height measurement), a GPS, and a new tree positioning device (PosTex).

Main steps

Considerable techniqualities are involved in a field inventory. In short, a field inventory includes the following steps:

1. Import a stand register
2. Set up a sample design
3. Set up an inventory and export data to a database file
4. Copy the database file to the field computer

   It is possible to distribute an inventory over several field crews just by distributing the same file created in the step above. PlanStart can handle this when importing back to the system.

5. Do field inventory with Ivent
6. Import field inventory data back to PlanStart

   If you have distributed the inventory to several computers, you can import them one by one until the whole inventory is completed.
