Workshop: Using air photos to map impervious surfaces and tree cover
Two geography professors in Morehead State University’s Institute for Regional Analysis and Public Policy (IRAPP) will present three free workshops describing a rapid, inexpensive means of using computer processed aerial photographs to map urban tree cover and impervious surfaces. These variables are important for city and county planners and others concerned with city/county development and the environment.
“As the 21st century moves forward, there is an ever-increasing amount of information available to help communities, businesses and individuals manage day-to-day operations and plan for future growth,” said Dr. Christi McMichael, assistant professor of geography.
“Modern and historical aerial photographs are a widely available, inexpensive (often free) data source for mapping cities and counties, and seeing how land cover has changed over time,” added Dr. Zach Bortolot, assistant professor of geography.
Workshop participants will receive free GIS data layers from the region, including recent color aerial photographs, land cover, streams, roads, elevation and soils, as well as a copy of a free GIS software package that allows users to display this data. Instructions for obtaining additional (mostly free) GIS datasets throughout Kentucky also will be provided.
“This workshop will assume no knowledge of aerial photography or geographic information systems (GIS),” Dr. Bortolot continued. “While everyone is welcome to attend, the workshop should be of particular interest to city and county government officials, and state and federal government employees whose jobs focus on the environment or land use planning.”
The workshops will be presented on consecutive Wednesdays: June 6 in the Lloyd Cassity Building on the MSU campus, June 13 at the Technology Center at West Liberty, and June 20 at MSU at Mt. Sterling. All workshops begin at 10 a.m. and will run approximately 90 minutes.
Additional information on the workshops is available from Dr. Bortolot at (606) 783-9436 or Dr. McMichael at (606) 783-5442. Preregistration is necessary as space is limited.
