USGS Transportation Overlay Map Service from The National Map

The USGS Transportation service from The National Map (TNM) is based on TIGER/Line data provided through U.S. Census Bureau and supplemented with HERE road data to create tile cache base maps. Some of the TIGER/Line data includes limited corrections done by USGS. Transportation data consists of roads, railroads, trails, airports, and other features associated with the transport of people or commerce. The data include the name or route designator, classification, and location. Transportation data support general mapping and geographic information system technology analysis for applications such as traffic safety, congestion mitigation, disaster planning, and emergency response. The National Map transportation data...

Dry Tortugas Reef Visual Census 2016

In 1998, the Florida Fish and Wildlife Conservation Commission's (FWC) Fisheries Independent Monitoring (FIM) program began a long-term monitoring effort of key reef fish populations in the Florida Keys National Marine Sanctuary. This effort was aimed at evaluating the relative abundance, size structure, and habitat utilization of specific reef fish species that are targeted by commercial and recreational fisheries.; Smith,S.G., et al. 2011,Multispecies survey design for assessing reef-fish stocks, spatially explicit management performance, and ecosystem condition.

Madagascar, Remaining Primary Vegetation

This map is a simplified version of the vegetation map of FARAMALALA (1988 &1995), which was derived from LANDSAT satellite imagery, and broadly maintained the vegetation zones defined by HUMBERT (1955). The remaining areas of good quality, primary vegetation were identified from this map and was then classified into two major types, one evergreen (eastern and central) and the other deciduous (western and southern). The evergreen forests include the humid forests (at low, medium and high altitudes), along with the sclerophyllous woodland remnants (Uapaca dominated) of central Madagascar. The deciduous formations include the seasonally dry forests of the west and north, and the southern, dry forests and scrublands.
