Description: High resolution buildings dataset for Porter County, IN. The primary sources used to derive this buildings layer were 2013 LiDAR data, 2013 Ortho imagery and 2012 NAIP imagery. Ancillary data sources included GIS data provided by Porter County or created by the UVM Spatial Analysis Laboratory. This buildingsdataset is considered current as of Summer, 2013. Object-based image analysis techniques (OBIA) were employed to extract building 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 1:2,500 and all observable errors were corrected.This dataset contains footprints for buildings and some large out buildings. Many garages and sheds are not included in this dataset.
