Making your own data useful in INSROP GIS

GIS data consists of a spatial component and a tabular component. The spatial component includes spatial co-ordinates (e.g. latitude and longitude) describing the location and shape of spatial features. The tabular component includes attributes describing the characteristics of the spatial features. In ArcView, the spatial features are displayed in a view, while the attributes can be used to classify the spatial features and thereby defining how they should be displayed.

ArcView can handle both spatial and non-spatial data sets. With spatial data we mean GIS data where the spatial and tabular components are stored permanently in a unified set of files (i.e. ARC/INFO coverages or ArcView shapefiles). However, non-spatial tabular data can be joined or linked (through common IDs) to a spatial data set and will then serve as an extended attribute table.

You may extend your INSROP GIS database by adding your own data, either data prepared in ARC/INFO format, as ArcView shapefiles or any other format ArcView can import, or by creating ArcView shapefiles from ASCII files. To create ArcView shapefiles from ASCII files, the following INSROP GIS functions are available:

If you store and document the data sets you obtain or create according to INSROP GIS requirements, these data sets become part of your INSROP GIS database and are then available for use as any other data set in the INSROP GIS database. The INSROP GIS requirements for storage and documentation are described in the following sections:
