Didger 2 from Golden Software converts data and boundary files between 21 different projections, including Unprojected Latitude/Longitude and UTM. The 16-bit versions of Windows use a coordinate system that limits the maximum paper size. The 32-bit versions of Windows (NT) do not have this limitation. There are several ways to work around the problem: To print a map on 24"x 40" paper at a scale of 1.0 in. = 1.

The downloadable ZCTA gazetteer files contain the latitude/longitude coordinates for each Census 2000 ZCTA. Coordinates for ZCTA internal points (calculated by considering the latitude/longitude of all bounding features and then creating an area-weighted average point inside the polygon) are also available in the TIGER/Line® Files.

Explaining this in detail is beyond the scope of this FAQ, but if you missed Geography 101, check out this NASA page for a good explanation.

Yes My World can convert data as long as you know what coordinate system the data is in. When you import the data, it will ask you.

Q19. I digitize my map and set the display and calibration units as Lat/Long, but when I export my map the units are in meters! Q20. I am having a problem printing ("Out of global memory" error, only a portion of the map prints, etc.).

There are a lot of speculative theories floating around. The following list includes a few of them.

It depends on where you got the data from. Lots of data that can be downloaded from the internet comes with metadata (data about data). You can usually find a section in the metadata describing the coordinate system that the data is stored in.

One might confuse the difference between degrees/minutes/seconds and Decimal Degrees. To convert from decimal degrees to degrees/minutes/seconds with 45.63248 as an example: Multiply by 60, to obtain 37.94880 – 37 is the number of minutes; 37 then will follow 45 degrees. To convert from degrees-minutes-seconds to decimal degrees using 45 degrees, 37 minutes, 57 seconds as an example:

quot; N, 100?20'11" W is a typical latitude and longitude coordinate. The coordinate above is the location of Pierre, South Dakota. Below you will find the break-down of the symbols above. Pierre is located 44 degrees, 22 minutes and 5 seconds north of the equator. Pierre is also located 100 degrees, 20 minutes and 11 seconds west of the Prime Meridian. The distance to Pierre can be calculated using the information above. The approximate distance to Pierre is 3061.

applicant would need to enter the name of a place nearest to their project location, and run a search for it. The results will include the latitude and longitude for the location.

Every point located on the equator (an imaginary great circle passing round the middle of the Earth) is at zero degrees of latitude. Zero degrees longitude is every point on the Greenwich Meridian or primary meridian - an imaginary line which runs from the North Pole to the South Pole. By international convention it runs through "the primary transit" instrument (main telescope) at the Royal Observatory in Greenwich. Check out the Royal Greenwich Observatory special visit.

Latitude and longitude may be obtained from the property deed or county plat maps available at the local library or county recorder. If the information cannot be obtained from the above sources, contact the DNR Emission Inventory Staff for assistance.

Post your data in unprojected latitude/longitude using decimal degrees, with west and south directions shown as negative values. Latitude is the Y and longitude is the X. For example, 105 degrees 30 minutes west would be represented as -105.5 degrees. To convert from degree-minute-seconds (dms) units to decimal degrees (d.dd), use the formula:
