This collection is a legacy product that is no longer supported. It may not meet current government standards. This inventory presents chronologically the satellite images acquired, orthorectified and published over time by Natural Resources Canada. It is composed of imagery from the Landsat7 (1999-2003) and RADARSAT-1 (2001-2002) satellites, as well as the CanImage by-product and the control points used to process the images. Landsat7 Orthorectified Imagery: The orthoimage dataset is a complete set of cloud-free (less than 10%) orthoimages covering the Canadian landmass and created with the most accurate control data available at the time of creation. RADARSAT-1 Orthorectified Imagery: The 5 RADARSAT-1 images (processed and distributed by RADARSAT International (RSI) complete the landsat 7 orthoimagery coverage. They are stored as raster data produced from SAR Standard 7 (S7) beam mode with a pixel size of 15 m. They have been produced in accordance with NAD83 (North American Datum of 1983) using the Universal Transverse Mercator (UTM) projection. RADARSAT-1 orthoimagery were produced with the 1:250 000 Canadian Digital Elevation Data (CDED) and photogrammetric control points generated from the Aerial Survey Data Base (ASDB). CanImage -Landsat7 Orthoimages of Canada,1:50 000: CanImage is a raster image containing information from Landsat7 orthoimages that have been resampled and based on the National Topographic System (NTS) at the 1:50 000 scale in the UTM projection. The product is distributed in datasets in GeoTIFF format. The resolution of this product is 15 metres. Landsat7 Imagery Control Points: the control points were used for the geometric correction of Landsat7 satellite imagery. They can also be used to correct vector data and for simultaneously displaying data from several sources prepared at different scales or resolutions.

Note: To visualize the data in the viewer, zoom into the area of interest. The National Air Photo Library (NAPL) of Natural Resources Canada archives over 6 million aerial photographs covering all of Canada, some of which date back to the 1920s. This collection includes Time Series of aerial orthophoto mosaics over a selection of major cities or targeted areas that allow the observation of various changes that occur over time in those selected regions. These mosaics are disseminated through the Data Cube Platform implemented by NRCan using geospatial big data management technologies. These technologies enable the rapid and efficient visualization of high-resolution geospatial data and allow for the rapid generation of dynamically derived products. The data is available as Cloud Optimized GeoTIFF (COG) for direct access and as Web Map Services (WMS) or Web Coverage Services (WCS) with a temporal dimension for consumption in Web or GIS applications. The NAPL mosaics are made from the best spatial resolution available for each time period, which means that the orthophotos composing a NAPL Time Series are not necessarily coregistrated. For this dataset, the spatial resolutions are: 100 cm for the year 1932 and 50 cm for the year 1950. The NAPL indexes and stores federal aerial photography for Canada, and maintains a comprehensive historical archive and public reference centre. The Earth Observation Data Management System (EODMS) online application allows clients to search and retrieve metadata for over 3 million out of 6 million air photos. The EODMS online application enables public and government users to search and order raw Government of Canada Earth Observation images and archived products managed by NRCan such as aerial photos and satellite imagery.

The orthophotographs used to produce this mosaic are acquired by aerial overview in order to meet the needs of the Southern Quebec Ecoforest Inventory (IEQM). These images serve, among other things, to feed the process of photo-interpretation and production of the ecoforest map essential for sustainable forest management. This mosaic is the result of an assembly of orthophotographs produced since 2002 and represents the most recent images from the ecoforest inventory. The spatial resolution is generally 20, 21, or 30 cm (with some exceptions of 8, 10, 12, and 500 cm). Spectral bands and colors of images vary: black and white (panchromatic [PAN]), infrared (IRP), or natural (red, green, and blue colors [RGB]). This mosaic covers almost all of Quebec south of the 52nd parallel. The images used to produce the mosaic are acquired in a cycle of about 10 years corresponding to the IEQM calendar. Note that imagery acquired through partnerships was excluded due to their more restrictive distribution license and was replaced by historical images from the ecoforest inventory or by satellite imagery when the latter was not available. The orthophotography mosaic is accessible for visualization only using a web mapping service (WMTS).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

We present the Waterloo Building Dataset for building footprint extraction from very-high-spatial-resolution aerial ortho imagery. Our dataset covers the Kitchener-Waterloo area in Ontario, Canada, contains 117,000 manually labeled buildings, and extends over an area of 205.8 km2. At a spatial resolution of 12 cm, it is the highest resolution publicly available building footprint extraction dataset in North America.

This data set contains ortho-rectified mosaic tiles, created as a product from the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative of the Port of Georgetown - CSCAP (Coast and Shoreline Change Analysis Program). The source imagery was acquired on March 05, 2010 and March 06, 2010. The true color images were acquired with an Applanix Digital Sensor System (DSS). Ortho-rectified mosaic tiles are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data. Data formats include .tif, .jpg, and .his files with associated metadata. The ground sample distance (GSD) for each pixel is 0.35 m.
