![]() ![]() View a sample image of the tile locationsĮRU Change Request - For FS partners that have updates to the data. The shapefile data is tiled into four tiles: Arizona North, Arizona South, New Mexico North, New Mexico South. ERUs are used to define historic/reference conditions within a mapping unit by integrating site potential (soil physical and chemical properties, geology, geomorphology, aspect, slope, climate variables, and geographic location), fire regime (historic and contemporary), neighboring vegetation communities, and seral state sequence. The framework represents all major ecosystem types of the southwest region, and represents a stratification of biophysical themes. This dataset includes a variety of constructed features, (e.g, fences, bridges, culverts, buildings, communication systems, gates, helipads, parking lots, shooting range, etc.) and non-constructed features which may include natural barriers and other features that need to be maintained spatially.Įcological Response Units (Southwestern Region) Category/Feature ClassĮcological Response Units - The purpose of this feature class is to be an ecosystem mapping tool across all of Arizona and New Mexico.Įcological Response Units (ERUs) facilitate landscape analyses and planning. ![]() ![]() This feature dataset includes constructed and non constructed features that support management needs and mapping. Imagery was controlled using Airborne GPS/IMU technology on board the aircraft at the time of acquisition.Ĭonstructed Features (Southwestern Region) Category/Feature Class Once scanned and inventoried, the digital files were then digitally stitched together to produce high resolution orthomosaics.įour band digital imagery was processed and triangulated and then the imagery was fully orthorectified and mosaicked for 30cm digital orthophotography. High resolution orthomosaics from Historical Aerial Photography and 30cm 4band orthophotos of Fire Sites in Arizona and New Mexico acquired by the USFS Southwestern Regional Office for various planning, design, research and mapping purposes.įilm rolls acquired by the Southwestern Regional Office were scanned by the Aerial Photography Field office (APFO) at 12.5 microns with a Leica DSW700 film scanner and delivered as digital files. Geospatial features describing the photo centers and footprints for these projects can be accessed in the Historical Aerial Photography feature service above, and the imagery can be requested from the Aerial Photography Field Office With projects dating back to 1972, this imagery serves as an important record of fire extent and damage. This spreadsheet lists all of the post fire aerial photography projects flown by the Southwestern Region. This database contains metadata on each mission indicating the original mission specifications and information on how to locate the associated rolls of film. Historical Aerial Photography Archive Missions (HAPAP) is a geodatabase that interfaces with a Map Viewer Search engine of all aerial photography projects completed in the Southwestern Region of the Forest Service. Photo Mission Area Polygons & Photo Centers It contains basic information like the activity subunit ID, administrative forest, ownership, state, planned date, accomplished date, completed date, method, equipment, funding, and many other items.Īerial Photography Mission Data (Southwestern Region) Category/Feature Class This data does not go into specifics of treatments (such as chemical treatments). Only records with an activity are included. This area feature class represents the locations of planned, accomplished and completed activity data that are recorded in the USFS Activities application FACTS.
