Land Cover 2019 Kitchener (TIF)

Metadata Link Land Cover 2019 Abstract: A gridded land cover map derived from aerial imagery and lidar terrain data. General Information Source Year 2019 Category Elevation Model Feature Type Grid LC Methodology High resolution land cover dataset for Kitchener,ON. Seven land cover classes were mapped: (1) tree canopy, (2) grass/shrub, (3) bare earth, (4) water, (5) buildings, (6) roads, and (7) other paved surfaces. The primary sources used to derive this land cover layer were 2019 LiDAR data and 2019 3 band orthomosaic imagery. Ancillary data sources included GIS data provided by Kitchener,ON or created by the UVM Spatial Analysis Laboratory. Object-based image analysis techniques (OBIA) were employed to extract land cover information using the best available remotely sensed and vector GIS datasets. OBIA systems work by grouping pixels into meaningful objects based on their spectral and spatial properties, while taking into account boundaries imposed by existing vector datasets. Within the OBIA environment a rule-based expert system was designed to effectively mimic the process of manual image analysis by incorporating the elements of image interpretation (color/tone, texture, pattern, location, size, and shape) into the classification process. A series of morphological procedures were employed to insure that the end product is both accurate and cartographically pleasing. Following the automated OBIA mapping a detailed manual review of the dataset was carried out at a scale of 1:2500 Meters and all observable errors were corrected.
