CorrectAltitude vs Tokyo Jisou Maps

Correct Altitude establishes your position using data from at least twelve GPS satellites. This app shows the altitude at your current location, and enables you to take altitude-and-date-stamped photographs. Hikers usually turn off their iPhones on mountain trails because of the poor signal. When turned on, the iPhone GPS will try to determine the current location with data from three GPS satellites; however, these co-ordinates are still inaccurate. CorrectAltitude triangulates position with a large number of GPS satellites in a 5-minute period enabling an accurate determination of altitude. The app automatically continues triangulating position by polling GPS satellites, and informs you when it has established a location accurate to within the tolerated range of error. The default for this range is 5 meters (approximately 16 feet). As an add-on function, it can display where you are (if the place has a name), and this can be useful for contacting rescue services in emergencies. CorrectAltitude has been tested on hiking trails in the Himalayas! Here is an example of an altitude-and-date-stamped photograph. The photograph is taken at the maximum resolution of your phone's camera and stored. GPS information is discarded. If the Notify mode remains set to "ON", you will continue to get updates on altitude every five minutes. To conserve the battery and stop repeated updates, you may prefer to set Notify mode to "OFF" after you have determined your altitude.

The "Tokyo Jisou Maps" is a map application that allows you to learn about the changes in the Tokyo region, based on the time axis from the Meiji era to the present day. From the Meiji era (1868-1912), when modern surveying began with the opening of civilization, to the Taisho and Showa eras, through the Heisei era (1912-1989), and up to the present day, we have captured many maps that have been continuously produced in a small smartphone that fits in the palm of your hand. The "Tokyo Jisou Maps" allows you to know the origins of the land in three dimensions by using the GPS function and the "time-layer" that overlaps multiple eras. Enjoy time travel with your smartphone! ------------------ Type of map to display ------------------ Old Map ·Early Meiji (1/5,000) 1876-1884 ·Early Meiji (1/20,000 1880-1884 ·Late Meiji 1903-1909 ·Immediately before the Great Kanto earthquake 1917-1928 ·Pre-war and wartime Showa 1927-1939 ·From the end of the war to the late Showa 1945-1962 ·Late Showa to Heisei 1984 - 1990 Terrain ·Elevation Tinted Hillshade Contemporary Map ·GSI Maps ·Apple Maps ·Satellite ·Satellite (Show Labels) Aerial Photograph ·1928 ·1936-1942 ·1945-1950 ·1961-1969 ·1974-1978 ·1979-1983 ·1984-1986 ·1987-1990 ·After 2007 ---------------- Coverage of old maps ---------------- Coverage of Tokyo Jisou Maps (Japan Map Center website) https://info.jmc.or.jp/jisoumaps/tokyo/boundary/ ---------------- Caution ---------------- ·An Internet connection is required to view the map. ·The use of the recorded maps is subject to procedures based on laws and regulations. ·The accuracy of the location of the map is not guaranteed.
