2.181. Stratum Layers

Stratum Layers

It is possible to define 3 stratum layers. Stratum Layers are used only in the Location Module.

Two methods of entering stratum layers are supported:

1) Centerline Depths

Depths at centerline define the stratum layers.

Figure 1. Centerline Depths

2) Extended Depths

In addition to centerline, depths at each side shot point define the stratum layers.

To enter Centerline depths for 2 layers:

1) Double click (or select Edit - Current Field Options menu) when the cursor is in the GND column. This will popup the Ground Layers by Range dialog.

2) Enter a ground type for layers 1 and 2.

3) Enter a depth for layer 1 (the depth of the bottom layer is assumed to be infinite).

To enter Extended depths:

1) Double click (or select Edit - Current Field Options menu) when the cursor is in the SSL or SSR column. This will popup the Extended Side Shot Edit dialog.

2) Click on the Options button. This will popup the Side Shot Data Mode dialog.

4) Click on the Layers button to popup the Ground Types and Layers dialog.
