Happy New Year Samoa!

Samoa switched time zones by redrawing the international dateline. The change occurred at midnight on December 29, 2011, taking the Pacific island nation straight into December 31, 2011. Neighboring American Samoa will remain on the eastern side of the dateline, resulting in a time difference of a whole day between the two territories, which are a mere 50 kilometers apart. Click on the map to get time zones or on the red rectangle to get more information on the change in Samoa.

Mapping HIV/Aids in the world

Having lived in Africa for 13 years, I have seriously experienced the influence of HIV/AIDS on populations in Central and Southern Africa. Aidsmap is mapping the statistics of the disease, results are published through a map service which I used to make this map. If you open the full map, you will be able to visualise many more statistics such as mortality rates and other health data. More information can be found on Aidsmap.

Cell phone towers around my house

Cell phone reception is terrible where I live, reason enough to check on the BIPT site where the cell phone antennas are placed around me. I mapped all antennas with a certain postal code based on their address and yes, there are not too many towers around me. Based on the BIPT code of the tower, you can find out whether it is shared among different operators. There are currently 8774 cell towers (approved or requested) in Belgium.

National Geographic Map

Remember the good old school maps? This map is designed to be used as a general reference map for informational and educational purposes as well as a basemap by GIS professionals and other users for creating web maps and web mapping applications. The map was developed by National Geographic and Esri and reflects the distinctive National Geographic cartographic style in a multi-scale reference map of the world. The map was authored using data from a variety of leading data providers, including DeLorme, NAVTEQ, UNEP-WCMC, NASA, ESA, USGS, and others. This reference map includes administrative boundaries, cities, protected areas, highways, roads, railways, water features, buildings and landmarks, overlaid on shaded relief and land cover imagery for added context. The map includes global coverage down to ~1:144k scale and more detailed coverage for North America down to ~1:9k scale. Although small-scale boundaries, place names and map notes were provided and edited by National Geographic, boundaries and names shown do not necessarily reflect the map policy of the National Geographic Society, particularly at larger scales where content has not been thoroughly reviewed or edited by National Geographic.

Airplane track map

You can easily find both ship and airplane track services on internet. Since these are sometimes made available in KML format, they can be added to a map. For the map below I added the locations and tracks of airplanes approaching Los Angeles Airport (LAX). You can click on the airplanes to get flight information, elevation and speed. Check altitude and speed near the airport and further away. There is a delay of 15 minutes between the real position of the plane and the position on the map. Beware the airplane symbol on the map does not indicate the flight direction! If you would like to view a real airplane tracking application based on the Esri Flash viewer, check out the Heathrow aiport WebTrak application which also gives you information on noise.

Carte de France (Rumsey)

Bernie Szukalski transmitted this link today in his ArcGIS.com RSS feed. The Carte de France was one of the first national surveys completed on the same scale, 100 toises (a toise was equal to 6ft and the equivalent scale today would be 1:86,400), according to a specific plan. It was led by several generations of the Cassini family (not to be confused with the Italian globemaker Giovanni M. Cassini) starting in the 1740's and continuing through the French revolution and Napoleon's time, to 1815. Four generations of the Cassini family held the position of director of the Paris Observatory, and three of those worked on the Carte de France: Jacques Cassini (Cassini II, 1677-1756); Cesar-Francois Cassini (Cassini III, 1714-1784); and Jean Dominique Cassini (Cassini IV, 1748-1845). The 182 sheets that comprise the map are superb examples of cartographic engraving. The use of trigonometric surveying techniques gave the map a high degree of accuracy for its time. Below you see an area in what is now Flanders:

NOAA Nautical Chart

Ever wondered what a map of the sea looks like? Below you find a part of the Nautical map of NOAA with separation zones and security zones.

Try a location search on "Florida" to see a different part of the map. What is technically new with this map? If you open the larger map you will find that the original extent of the saved map is completely different. With the current version of ArcGIS.com, the default embedded sharing is taking over the current zoom extent of the map, not the original saved map. Much easier to embed exactly that part of the map you want to show!

Global Climate Observation System (GCOS)

I found this dataset on the Geo.Data.GOV geoportal. The Global Climate Observing System (GCOS) provides an operational framework for integrating, and enhancing as needed, observational systems of participating countries and organizations into a comprehensive system focused on the requirements for climate issues. GCOS builds upon, andworks in partnership with, other existing and developing observing systemssuch as the Global Ocean Observing System, the Global Terrestrial Observing System, and the Global Observing System and Global Atmospheric Watch of theWorld Meteorological Organization. It is co-sponsored by the World Meteorological Organization (WMO), the Intergovernmental Oceanographic Commission (IOC) of UNESCO, the United Nations Environment Programme (UNEP) and the InternationalCouncil for Science (ICSU). GCOS addresses the total climate system including physical, chemical and biological properties, and atmospheric,oceanic, hydrologic, cryospheric and terrestrial processes. I added a link to a Bing Birds Eye View image for each station. Zoom out on that image if you have a blurred view, it means the available resolution for Bing is not high at that spot.
