The following flowcharts show the steps required to perform data
acquisition operations using DT-Open Layers. For illustration
purposes, the DataAcq SDK functions are shown; however, the
concepts apply to all DT-Open Layers software.

Note that many steps represent several substeps; if you are
unfamiliar with the detailed operations involved with any one step,
refer to the indicated page for detailed information. Optional steps
appear in shaded boxes.
