The Plant Records Department at the Missouri Botanical Garden maps many of the features in the Garden, including the paths, water features, buildings, planting beds, and of course, plants. This is accomplished through the use of Geographic Information Systems, or GIS, technology.
The Plant Records Department uses GIS software products by ESRI (Environmental Systems Research Institute) to manage our geographic data. A high resolution orthophotograph (4-inch resolution) is used as the base of the GIS. ESRI's ArcMap software is used to build layers on top of this orthophoto. Features in the Garden such as paths, buildings, and water features are simply "drawn" on top of the orthophoto using and ArcMap's drawing tools.
