The Shore Unit Classifications Polygons depict the most current areas of Shorezone mapping for the Province of British Columbia. Shorezone is an aerial imaging, habitat classification, and mapping system used to inventory alongshore and across-shore geomorphological and biological attributes of the coast. Habitat attributes are interpreted from oblique aerial imagery acquired during the lowest tides of the year. The mapping project was first developed as an oil spill response tool for British Columbia, and now ShoreZone extends from Oregon to Alaska and has many other uses including ecological studies, marine conservation planning, coastal flooding and vulnerability assessments, and community education.

The Canadian Hydrographic Service (CHS) Low Water Mark Lines provide alongshore and across-shore geomorphological and biological attributes of the low water mark shoreline. The lines are used in the CHS nautical charts to represent the level reached by sea water at low tide.

The Canadian Hydrographic Service (CHS) High Water Mark Lines provide alongshore and across-shore geomorphological and biological attributes of the high water mark shoreline. The lines are used in the CHS nautical charts to represent the level reached by sea water at high tide.

The Shorezone Biobanding Lines are a linear representation of the various types of biota (flora and fauna) and their distribution, or lack thereof, found in the shoreunit.

The Shoreunit lines is part of the Physical Shore-Zone Mapping System. It is a scheme designed for the classification of the shoreline type, materials, forms and processes that occur or operate along the coast of British Columbia. It has been specifically developed to provide an inventory of the physical character of the shore-zone and to show their distribution, extent and location.

The Shorezone Biobanding Polygons are an area representation of the various types of biota (flora and fauna) and their distribution, or lack thereof, found in the shoreunit.

A point file showing a collection of specific GPS spatial points recorded during the video taping of the shoreline. The points are represented by a specific latitude and longitude taken at a specific date and time. Each are associated with a specific BIOSLIDE at a specific SHOREUNIT in the Shorezone data

The Observed Habitat Lines show the various types of particular habitat that have been observed or calculated by biologists as well as an expectation of different species found in the habitats. Each bioarea has several observed habitats, and it is the combination of the bioarea and habitat observed number that identifies each unique observed habitat.

The Okanagan Lake kokanee shore spawner data set is comprised of two combined data sets. The historical data set for the years 1974, 77, 78, 79 and 80 and a more recent data set collected from 2001 to 2013. The historical data was derived from information collected in the field and hand drawn onto air photographs. Ministry staff circled Okanagan Lake in a boat one time each year and recorded fish numbers and spawner locations onto air photographs that were digitized in 2006 to make up the historical data set.
