…from the ESRI Map Book, Volume 24

“This map shows the risk for mass removal and the susceptibility level for trees. It contains city blocks and shadow relief created on the Bogotá digital elevation model (DEM). Mass removal occurs when large quantities of ground slide and shift after earthquakes, tremors, or heavy rains. Mass removal seriously damages urban infrastructures and, in many cases, threatens human life.

“The map indicates trees located in zones of risk for mass removal as well as the relief of the zone. The map is a valuable tool for the entities responsible for preventing and responding to mass removal. It shows the places where they have to intervene.

Map of the Day: For the Love of the Lake, Historic Lakeshore Communities

…from the ESRI Map Book, Volume 24

“This map is part of a series of community maps of the town of Georgina produced by residents. Its purpose is to showcase what residents think is important about their neighborhoods and to help protect and enhance what is special. The map points out a nature reserve and a local stream, both important habitats for conservation.

“The Deer Park Road area is an important mature mixed forest providing habitat for a wide range of animals, birds, and amphibians. Private landowners in the area worked together with the Lake Simcoe Region Conservation Authority to create the Arnold C. Matthews Nature Reserve in order to preserve and steward the land in perpetuity.

“Boyer’s Stream connects protected core lands and Lake Simcoe, providing habitat for waterfowl, amphibians, and marsh birds and a potential upstream fish spawning route.

“This map analyzes biological corridors (linear strips of vegetation that provide a continuous or near-continuous pathway between habitats) and tree crowns (the area above the trunk) in the locality of Chapinero, Bogotá. It shows the trees modeled with an equatorial diameter buffer and integrated with a dissolve for biological research. The trees with their crowns close together serve as a biological corridor for local birds and insects. They also provide shade for people living in the city.

Map of the Day: Human Use and Management Chart, North Coast Section of Oregon

…from the ESRI Map Book, Volume 24

“The State of Oregon and Oregon’s Ocean Policy Advisory Council (OPAC) need geospatial information for the coastal and offshore areas of Oregon for planning. This map is one in a reference chart series showing human use and management. Generated initially to support the Oregon marine reserve proposal process, these maps were part of a larger effort that also mapped biological resources and seafloor and shoreline.

“The sea has traditionally been familiar territory to the fishing community. Other interests such as potential wave energy projects and marine conservation have emerged. The maps help OPAC members and others understand current and potential use of specific areas. The maps are used to facilitate planning, state and local discussions, and education efforts.
