| Dataset | Is basically the equivalent of a spatial resource. In Orbit, all spatial resources are called Datasets.It is either vector data, image data or hybrid. \\ Datasets contain general properties, a data modeling definition, data, and possible legend and/or labeling specifications. Often referred to as a Layer, however it is more precise to refer a Model to a Layer. |
| Dataset List | The list of Datasets currently accessed or opened within Orbit GIS, also referred to as Table of Contents. |
| EOS | Short for Internet Orbit Server. IOS extends EOS with internet enabling supplements, such as OGC WMS/WFS services. Orbit FlashMap is designed for website & browser integrated map viewing. |
| Focus Object |  |
| Legend | A definition of how a single dataset must be graphically drawn. |
| Legend Display | The graphic representation or the chosen symbolics defined by a legend definition. Appears in the dataset list and optionally on a printout. |
| MapCanvas | The graphic representation of the contents of one or more datasets. |
| Model | Subset of a dataset that holds an exact structural definition of spatial information objects. A Dataset contains at least 1 Model. All objects belong to exactly 1 Model within a Dataset. |
| Object | see Spatial Information Object |
| Part (Object) | |
| Resource | A physical set of data, either spatial or non-spatial \\ A resource is some quantity of data, generally speaking spatial data, that is stored in some place in some way. Most spatial resources are either stored as files in a normal file system, or in servers (RDBMS, OODBMS, internet service or other). \\ Orbit Technology uses Resource Drivers to connect to each format of storage. |
| Resource Browser | The Orbit GIS user interface to select resources from the file system or a remote server and add it to the workspace. |
| Resource Drivers | A Resource Driver is an Orbit extension allowing Orbit to read (and optionally write) spatial data in a specific storage format. Orbit comes with a Resource Driver API allowing everyone to develop drivers for any storage format. Orbit GIS is standard equipped with default implementations of this API for a range of popular storage formats. |
| Segment |  |
| Selected Object |  |
| Sequence of points |  |
| Spatial Information Object (SIO) | Entity that holds information about a single real-world feature. All spatial data from any source is presented as SIO within Orbit. |
| Storage Format | A physical form in which data is stored on disc. |
| Vertex |  |
| Workspace | A range of settings including a list of datasets and view preferences. Bundles your choice of datasets and settings into a single file for easy and fast recovery. Also referred to as a “project”. |
