Terms and Definitions

DEM/DTM Production – A digital elevation model (DEM) is a digital representation of ground surface topography or terrain. It is also widely known as a digital terrain model (DTM). A DEM can be represented as a raster (a grid of squares) or as a triangular irregular network.

Digital Mapping – The processes of acquiring (capturing), transforming and presenting spatial data held in digital form.

Ecosystem – The interconnectedness of organisms (plants, animals, microbes) with each other and their environment.

Elevation Model – An image (or picture) showing the elevation of each point on the ground. The brighter the point, the higher the ground is at that point.

Environmental Audit – This is an independent assessment of the property to evaluate any environmental risks that may be present.

Environmental Consulting – A form of compliance consulting, in which the consultant ensures that the client maintains an appropriate measure of compliance with environmental regulations and stewardsip practices.

Environmental Management – Managing the productive use of natural resources without reducing their productivity and quality.

Environmental Planning – All land use planning activities with the objective of preserving or enhancing environmental values or resources.

Environmental Stewardship – The concept that we are entrusted with the care and protection of our planet. Promoting good environmental stewardship can be through safeguarding of our air, water and soil, as well as other natural resources.

Forest Land Management – The protection, manipulation, and utilization of the forest to provide multiple benefits, such as timber and energy production, air purification, water capture, storage and transpiration, wildlife habitat, recreation, etc.

GIS (Geographic Information System) – System that captures, stores, analyzes, manages, and presents data that are linked to a geographic location.

Hydrography – The scientific measurement and description of the physical features and conditions of fresh waters and shorelines.

Land Base Information – Information describing physical features of land and it’s surface resources. Existing on or operating from land, rather than from the sea or the sky

Land Use Planning – The process by which decisions are made on future land uses over extended time periods, that are deemed to best serve the general welfare of society.

Photogrammetry – The science of using aerial photography and other remotely sensed imagery and data to obtain measurements of natural and man-made features on the earth

Reconnaissance –  The act of scouting or exploring to gain information.

Remote Sensing – Gaining information about an object without coming in direct contact with it. Eg, satellite or airborneimaging, lidar etc.

Remote Sensing Analysis – The act of studying, measuring or determining the meaning, metrics or values of remotely sensed information or data to derive further information about objects or features.

Silviculture – The establishment, care, growth and development of forests in order to obtain a product or provide a benefit; forestry, reforestation, afforestation

Forest Health Surveys – The act of measuring and monitoring forest health (e.g disease, insect infestations etc.)

Site Restoration & Reforestation – The act or process of restoring a site to it’s natural state; replanting a forest after natural or man-made disturbance.

Socio-Economic Analysis – Of or pertaining to a combination of social and economic factors.

Spatial Analysis – The process of extracting or creating new information about a set of geographic features.

Thematic Maps – A geographic map that displays the spatial pattern of a theme or series of attributes.

Timber Management – Production and identification of salable wood products from forests on a sustained yield basis

Topographic Base – A map that indicates the topography of the ground, and includes physical features such as rivers, vegetation access and habitation.
