The Nova Scotia Hydrographic Network is an enhanced version of the Nova Scotia Topographic Database's Water Features theme. This dataset includes network spines for connectivity of water flow and various attribution for flow direction, priority of water flow and toponymic objects where applicable.

A shapefile of freshwater water bodies hat have been sampled as part of the Nova Scotia Lake Survey. The Nova Scotia Lake Survey program is a partnership initiative between Nova Scotia Environment (NSE) and Nova Scotia Fisheries and Aquaculture (NSDFA) to inventory lakes throughout the province determining baseline water quality, in support of both sport fisheries and water resource management areas. The following weblink connects to a Nova Scotia Environment web map that includes the locations of the monitored lakes within the province and an alternative method for downloading the same lake chemistry dataset: http://nse.maps.arcgis.com/apps/webappviewer/index.html?id=7ded7a30bef44f848e8a4fc8672c89bd

The Nova Scotia GeoNAMES dataset contains all current approved and offical geographic names for the Province of Nova Scotia. The named features in the dataset include Populated Places, Administrative Areas, Water and Terrain Features, Vegetation Areas, some Manmade Features, and Undersea Features. Geographic names in the Province of Nova Scotia are approved by the province's representative on the Geographical Names Board of Canada.

To assess the current distribution of kelp beds and other macroalgae in Nova Scotia and Southwest New Brunswick, subtidal drop camera surveys were performed from 2022-2023 at 140 sites. For each site, a GoPro HERO 10 camera was towed along a deep (7-12m) and shallow (3-5m) depth contour until 20 images were acquired per depth. Where possible, species were identified from photos, with particular care given to kelps (defined here as orders Laminariales and Tilopteridales) and fucoids (order Fucales). Crust-forming algae was not counted. Percent cover was calculated using a 10x10 point grid overlaid on each image and recording the dominant cover type at each point. The depth (in meters) of each photo after correcting for tide height ranged from ~0.5m to ~12m. Depths were corrected to chart datum (lowest astronomical tide) using tide predictions from the nearest tide station, taken from tides.gc.ca. Sampling was performed between July and October.

Nova Scotia Topographic DataBase - Water Features Public Nova Scotia Topographic DataBase - Water FeaturesLands, Forests and Wildlife View Data Part of the Nova Scotia Topographic Database the Nova Scotia Hydrographic Network (Water Features) is updated and maintained from aerial photography. Lakes, Rivers, Islands and many other features are collected and networked into a seamless relation data base. Toponyms are included in the attribute table for named hydrographic features. Hydrographic feature codes and their descriptions are provided with the download in a NSTDB feature code table.
