What is Latitude?

We can imagine the Earth as a sphere, with an axis around which it spins. The ends of the axis are the North and South Poles. The Equator is a line around the earth, an equal distance from both poles. The Equator is also the latitude line given the value of 0 degrees. This means it is the starting point for measuring latitude. Latitude values indicate the angular distance between the Equator and points north or south of it on the surface of the Earth.

A line connecting all the points with the same latitude value is called a line of latitude. This term is usually used to refer to the lines that represent values in whole degrees. All lines of latitude are parallel to the Equator, and they are sometimes also referred to as parallels. Parallels are equally spaced. There are 90 degrees of latitude going north from the Equator, and the North Pole is at 90 degrees N. There are 90 degrees to the south of the Equator, and the South Pole is at 90 degrees S. When the directional designators are omitted, northern latitudes are given positive values and southern latitudes are given negative values.

What is longitude?

Prime Meridian

Lines of longitude, called meridians, run perpendicular to lines of latitude, and all pass through both poles. Each longitude line is part of a great circle. There is no obvious 0-degree point for longitude, as there is for latitude.

Why measure in Degrees?

The measurement is in degrees because fundamentally, Latitude is an angular measurement originating from the center of the Earth. If a line is drawn from the center of the Earth to any point on the globe, and another line is drawn from the center of the Earth to any point on the equator, the resulting angle is the degrees of latitude, either North or South depending in which hemisphere the original point lives.

Are Latitudes Different Sizes?

Because the Earth is generally spherical, latitude parallels can be very different sizes. The longest is the equator where the latitude is 24,901 miles (40,075 kilometers) while at the North and South poles the Latitude circles are a single point.

How do you convert to Degrees from Degrees:Minutes:Seconds?

The latitude and longitude are input in degrees, but Latitude is often given in degrees minutes and seconds so you might need to convert to degrees from degrees:minutes:seconds. There are 60 seconds in 1 minute and 60 minutes in 1 degree. So, for example:

65:45:36 south latitude converts to

-(65 degrees +

45 minutes * (1 degree/60 minutes) +

6 seconds * (1 minute/60 seconds) * (1 degree/60 minutes))

= -65.76 degrees latitude

What is longitude?

Lines of longitude, called meridians, run perpendicular to lines of latitude, and all pass through both poles. Each longitude line is part of a great circle. There is no obvious 0-degree point for longitude, as there is for latitude. Throughout history many different starting points have been used to measure longitude.

What is Aerial Photography?

Aerial Photography is the most detailed accurate mapping commonly available, it is used to locate identifiable points of interest using a "view from above" approach. You will be able to see trails, ridges, fence lines, trees, agricultural land, houses, roads, lakes & ponds, streams, and other interesting features. One common complaint of aerial photography is the lack of a terrain component. That is, when viewing an aerial, it is difficult to interpret the "lay of the land ".

What are Contours?

Topography such ascontours show changes in elevation. These can be used to locate high & low points, as well as ridges to give you an added advantage when planning your outdoor trip. Contours represented on topographic maps are extremely useful, especially when overlaid on aerial photography as done with our Aerial Topo product.

What are the contour intervals?

The contour intervals are 5 Meters.

What is Latitude & Longitude?

Latitude and Longitude are the coordinates that are used to find a location on the earth. You can enter these coordinates into our Search page and our mapping application will take you directly to that location. For more information on Latitude & Longitude you can visit

What if I can’t find my exact address?

Should I zoom in before or after I center the Green Map Location Box?

The quickest way to create a maps is as follows:

1. Pan in the appropriate direction of the property of interest, until that property is centered in the map window.

2. Zoom in to an appropriate scale to best fit the property in the Green Map Location Box.

3. Adjust the Green Map Location Box to correctly center the property. Keep in mind that if you move the Green Map Location Box before you zoom in on the map, the application will zoom in to the center of the overall map window. This could cause the property of interest to be off the map window at a closer scale. If you follow the steps above that will not happen.

How do I move around in the Map?

Clicking on the Green Arrows surrounding the map will move move you in the appropriate direction that you choose.

How do I zoom in and out on the map?

On the left side of the map there is a tool for zooming in and out (see image below). To zoom in closer on the map you click on the apprpriate level you want to see. The default is 1:18000. If you want to zoom in closer you can click on the 1:12000 or 1:6000 layer. To zoom out farther you would click on 1:24000, 1:30000, or 1:36000. You can also click on the "+" symbol at the top of the tool to zoom in one level closer, or you can click on the "-" symbol at the bottom of the tool to zoom out one level.

What is the Green Box in the middle of the map?

That is the map location box. This box is there to show the user what area will be printed on the map. You will notice that when you change from Portrait to Landscape on your map optionthe new map layout. The same goes with a 36” map option. Click on the location on the aerial photo that you want to be centered on your map and the Green Box will move to that locations and click the Refresh Map butting, the orientation of the Green Box will change to reflect .

What area's do you have up-to-date Aerial Photography for?

We now have access to High Resolution Color Aerial Photography for most of the United States. Due to the large file size, we do not display this imagery over the internet. However, it will be used when printing a map in any area where the up-to-date aerial photography is available. For the following areas we have New Color Aerial Photography. the Dark Blue area is available now, the Dark Green area will be available in the near future, and the White is not available at this time.

Can I add my GPS data to my map?

Yes, this is a custom mapping product. The price will therefore depend on the type and amount of data you have. Please contact us for more information at info@mappingtheoutdoors.com

What are the differences in paper types?

13x19” maps come in two different paper types.
• Regular paper is a normal printing paper like you would use at home, however it has a bright white, ultra smooth coated finish.
• Waterproof paper is a waterproof/weatherproof paper. It is a more heavy duty paper, meant for taking out in the field with you. It is puncture resistant, and tear resistant as well.
36” maps also come in two paper types:
• Waterproof paper is a waterproof/weatherproof paper. It is a more heavy duty paper, meant for taking out in the field with you. It is puncture resistant, and tear resistant as well. It is the same exact paper as the 13x19" Waterproof Paper.
• Glossy Photo paper is similar to the type of paper photo labs use to print high quality photo’s. It is a heavier paper that doesn’t crease or bend as easy, and has a High Gloss finish.

What is the difference in Portrait and Landscape?

Portrait is orientated with the Long Edge of the paper (19”) up and down, as illustrated below:

How precise can we be with latitude and longitude?

Degrees of latitude and longitude can be further subdivided into minutes and seconds: there are 60 minutes (') per degree, and 60 seconds (") per minute. For example, a coordinate might be written 65° 32' 15". Degrees can also be expressed as decimals: 65.5375, degrees and decimal minutes: 65° 32.25', or even degrees, minutes, and decimal seconds: 65° 32' 15.275". All these notations allow us to locate places on the Earth quite precisely – to within inches. A degree of latitude is approximately 69 miles, and a minute of latitude is approximately 1.15 miles. A second of latitude is approximately 0.02 miles, or just over 100 feet.

A degree of longitude varies in size. At the equator, it is approximately 69 miles, the same size as a degree of latitude. The size gradually decreases to zero as the meridians converge at the poles. At a latitude of 45 degrees, a degree of longitude is approximately 49 miles. Because a degree of longitude varies in size, minutes and seconds of longitude also vary, decreasing in size towards the poles.

Here are further guidelines.
