NSDL teaching resources related to “coordinates”

This graphical locator makes it possible to find location data about places in the northwest quarter of the Earth. Most of the locations in this database are in the United States, but a limited number exist for Canada and Mexico. Users may choose maps by state, click directly on U.S. and hydrologic (HUC) maps, or enter latitude and longitude, township range and section, or a UTM. Data includes latitude, longitude, gradient, elevation, UTM (Universal Time) zone, legal name, state and county, topographic map names of the area and nearby named locations.

GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus. As an interactive geometry system, GeoGebra can help you do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. Equations and coordinates can also be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.

This map and summary describe the Antarctic Circumpolar Current (ACC), which is the most important current in the Southern Ocean and the only current that flows completely around the globe. The ACC, as it encircles the Antarctic continent, flows eastward through the southern portions of the Atlantic, Indian, and Pacific Oceans. Links are provided to summary text detailing velocity and hydrographic observations, plots such as average current speed, drifting buoy positions, sea surface temperature maps, and HYbrid Coordinate Ocean Model (HYCOM) simulations. References are also included.

In this activity, students will develop and be able to manipulate a grid coordinate system on a 7.5 minute series local topographic map. Students will learn to use the grid coordinate protractor (GCP) to plot azimuth values as a means of indicating direction on these maps; they will also learn to perform simple map traverses.

Figure 1: Homology model of the human B0AT1 transporter. Legend: The homology model was created using the Swiss-Model web server (54). Subsequently, the substrate and Na+ ion were reintroduced at the original coordinates. The figure was generated using PyMOL (DeLano Scientific). A: the view from the side (extracellular side top). B: the transporter from top. Helix 1 is depicted in yellow, and helix 6 is depicted in blue. Putative regions with ?-sheet conformation are also depicted in yellow. The backbone of the protein is highlighted.

Torsten H├Ągerstrand’s influential paper, What about People in Regional Science? published in 1970, argued that regional scientists should address the individual human element in their aggregate models, and examine the spatial and temporal coordinates of human activity. The spatial-temporal model that he unveiled was destined to change the course of history in the social sciences.
