The term “horizon” refers to the top of each stratigraphic unit that will be represented in a corresponding | The term “horizon” refers to the top of each stratigraphic unit that will be represented in a corresponding solid, HUF unit, or 3D mesh layer. Horizons are numbered consecutively in the order that the strata are “deposited” (from the bottom up). Horizons can be assigned to [[GMS:Boreholes|boreholes]], [[GMS:TIN Module|TINs]], and [[GMS:Coverages|coverages]]. Beginning with version 9.0, [[GMS:Raster Catalog|raster catalogs]] can also be used to define horizons. | ||
Once horizons have been assigned to boreholes, TINs, and/or [[GMS:Rasters|Rasters]], the [[GMS:Horizons Wizard|''Horizons Wizard'']] can be used to create solids, 3D mesh, or HUF data. | Once horizons have been assigned to boreholes, TINs, and/or [[GMS:Rasters|Rasters]], the [[GMS:Horizons Wizard|''Horizons Wizard'']] can be used to create solids, 3D mesh, or HUF data. | ||

Horizons are defined at borehole contacts (interface between different materials on a borehole log) by double-clicking on a contact with the [[GMS:Borehole Tool Palette|'''Select Contact''']] tool. The ''Contact horizon ID'' dialog is used to manually enter horizon IDs. More than one contact can be selected and assigned the same horizon ID. The [[GMS:Creating and Editing Boreholes#Auto Select|''Boreholes'' | '''Auto Select''']] command can be helpful in assigning horizons to a large group of boreholes. | Horizons are defined at borehole contacts (interface between different materials on a borehole log) by double-clicking on a contact with the [[GMS:Borehole Tool Palette|'''Select Contact''']] tool.

This dialog can be accessed by right-clicking on a TIN in the [[GMS:The GMS Window|Project Explorer]] and selecting the '''Properties''' command. Each TIN can be assigned one Horizon ID. Each TIN included in the horizons algorithm must have a horizon ID. If wanting to ignore a TIN, this can be done by setting the horizon ID to zero. | ||
