Foundation Geospatial Data
Foundation Geospatial Data Your location-based decision making starts here On this page Skip to the content What is Foundation Geospatial Data? Foundation geospatial data (FGD) are the spatial layers common to mapping. These layers include roads, rivers, lakes, political boundaries, imagery, and elevation. While the list of things people map is endless, most maps use these layers. Government FGD is an authoritative and trusted source for users in many sectors for mapping and analysis. FGD criteria FGD must meet these criteria: Themes Organizing FGD by themes makes it easier to manage and for users to discover. Categories such as physical, ecological or infrastructure bundle FGD into non-technical groupings. FGD’s full potential is evident when data across themes are used together to provide value-added context, for example, when combined on a topographic map. Transportation Water Elevation and depth Imagery Infrastructure Land Parcel and property Place names Administrative boundaries Addressing Geodetic control Transportation The transportation theme includes roads, trails, railroads, airports and other features associated with the transport of people or goods. This data supports a wide range of needs such as emergency response, disaster planning, resource access, route planning, traffic safety, congestion mitigation and tourism. Transportation FGD layers in the Thunder Bay area Picture of transportation Foundation Geospatial Data layers in the Thunder Bay area on top of imagery. Water The water theme is made up of surface hydrology features including lakes, rivers, streams, dams, falls and rapids. This data supports a wide range of needs such as forest management planning, flood mitigation, emergency response, mitigation of invasive species and tourism. Water FGD layers in Caribou Falls Picture of water Foundation Geospatial Data layers near Caribou Falls on top of imagery. Elevation and depth Elevation and depth data represent the height of land or bathymetric depth of water relative to mean sea level. Elevation geospatial data can be represented as a continuous surface or as features (points, lines, polygons). The most common types of elevation data include Digital Terrain Models (DTM) depicting bare earth elevation and Digital Surface Models (DSM) depicting all surfaces on the earth including ground, trees and buildings. Elevation and Depth FGD layers in Millbrook Overhead view of a Digital Terrain Model (DTM) showing height of land and bathymetric depth in Millbrook. Imagery This theme includes aerial and satellite images of the Earth's surface. Imagery is the basis from which most other geospatial data is created and is fundamental to all geospatial business needs. Imagery geospatial data can be represented as 2-dimensional or 3-dimensional (stereo) imagery. Stereo imagery can be used to create elevation geospatial data. Imagery is used as a base map for most common web-mapping applications. Imagery FGD layers in Sault Ste. Marie Imagery showing shoreline and vegetation near Sault Ste. Marie.
