Southern Ontario Land Resource Information System (SOLRIS) land use data

Description

The Southern Ontario Land Resource Information System (SOLRIS) is a landscape-level inventory of natural, rural and urban areas. Version 1.1 covering the Greater Toronto Area (GTA) was released in 2007. Version 1.2 (JPG) was released in November - December 2007. In April 2008, the Geospatial Centre received updates to version 1.2, with landcover coverage for all of Southwestern Ontario, Central Ontario, and Eastern Ontario. In 2019, the Geospatial Centre received version 3.0, data that covers the date ranges from 2000-2015 in Ecoregions 7E, 6E and 5E (Growth Plan for the Greater Golden Horseshoe Study Area and an Eastern Ontario extension to the Forest Resources Inventory boundary).

SOLRIS was developed to support landscape-scale planning initiatives in southern Ontario such as source water protection, biodiversity conservation, natural spaces, and state of resources reporting. The SOLRIS inventory is a compilation of data from various sources including topographic maps, aerial photos and satellite imagery. Computer modelling, visual interpretation and field validation were used to create a seamless inventory for Southern Ontario.
