Introduction

A schema is a type or domain specification for folders and datasets that will filter menus and commands of the same type. Thus only relevant menus will be visible for a specific schema.

One can assign schemas to the objects in the project manager in order to add domain specific behavior. A schema contains:

• An icon that reflects the domain, such as a multibeam survey or seismic cube.
• A set of command objects specifically designed to operate on the domain-spesific datatype

By default datasets are organized into data types, such as points and lines (polydata), grids (structured points) etc. Read more about Geocap Data Types. These are basic geometric types that contain little information about the domain in which they operate. E.g. coast lines, bathymetric profiles and boundary polygons are all lines (polydata), but the way we work with these types of data are very different and so it is only natural to classify them into different categories. This higher level of classification is made possible by schemas. 

Notice that the dataset types are the same, while the schemas are different

Geocap comes with a list of predefined schemas where each schema will have a set of commands that can be performed on datasets with that specific schema. The full list of schemas can be found under Edit > Schemas.

All schemas are customizable and you can of course create your own schemas.
