MAPTOOLS PRODUCT -- UTM SLOTS FOR 1:31,680 1 INCH = 1/2 MILE The 1:31,680 scale represents a distance equivalence of 1 inch = 1/2 mile. When I created this tool, I had the McKenzie Boundary Waters maps in mind. Since then I've discovered that Halfmile's pdf maps of the Pacific Crest Trail also use this scale, have a 1km UTM grid on them, and are a great match with this tool. The Philmont Scout Ranch's sectional maps are also a good match with MAPTOOLS PRODUCTS -- CUSTOM DECLINATION REFERENCE SHEET Now it time to create your customized Declination Reference Sheet. The first panel you will see is a declination diagram for the location you specified with the date the declination was calculated. Depending on your choice, either True North or Grid North will be shown pointing straight up. The angles between the three north references will be LAT/LON FORMATS AND SYMBOLS DDD.DDDDD°32.30642° N 122.61458° Wor +32.30642, -122.61458. This is the format you'll find most computer based mapping systems displaying. The coordinates are stored internally in a floating point data type, and no additional work is required to print them as a floating point number. Often the N-S and E-W designators are omitted.

We will print it out using a color laser printer onto Rite-In-The-Rain (tm) paper. You will get a folded pocket sized weather proof reference sheet, made just for you. MAPTOOLS PRODUCT -- 1:24,000 POCKET SIZED SLOT TOOL This tool enables you to plot UTM coordinates to a 10 meter accuracy within a 1 kilometer grid square.

You want the result to fall between 0° and 360°, so if the forward bearing is less than 180°, add 180° to it, and if it's greater than 180°, subtract 180°. Calculating a back bearing.

MORE DETAILS ABOUT THE UTM COORDINATE SYSTEM More details about the UTM coordinate system. The Universal Transverse Mercator projection and grid system was adopted by the U.S. Army in 1947 for designating rectangular coordinates on large scale military maps. UTM is currently used by the United States and NATO armed forces. With the advent of inexpensive GPS receivers, many other mapusers
WHY USE UTM COORDINATES The UTM coordinate system offers the following benefits: UTM Provides a constant distance relationship anywhere on the map. In angular coordinate systems like latitude and longitude, the distance covered by a degree of longitude differs as you move towards the poles and only equals the distance covered by a degree of latitude at theequator.
DIFFERENCES BETWEEN MGRS AND USNG MGRS allows you to reference an entire 100,000m square area, e.g. 10S EH, whereas USNG suggests at least two digits and thus the largest area that can be described is a 10,000m square, e.g. 10S GJ 0 4. The USNG does not specifically prohibit 100,000m truncation, but instead omits it from the standard document, whereas the MGRS standard MAPTOOLS - MAP SCALE CALCULATOR Calculate map distance given map scale and ground distance.

On the back side, the ruler has distance in meters on one edge, and distance in either miles MAP TOOLS -- RULER DESIGN Map Scale. Enter the map scale you want to use this ruler with. It's typically printed somewhere on the map in a ratio format like "1:25,000" For this example you would enter 25000 in the input field. If you only have a distance equivalence, like 1 inch equals 1 mile, visit our scale calcuator to get a scale ratio. MAPTOOLS PRODUCT -- UTM SLOTS FOR 1:31,680 1 INCH = 1/2 MILE The 1:31,680 scale represents a distance equivalence of 1 inch = 1/2 mile. When I created this tool, I had the McKenzie Boundary Waters maps in mind. Since then I've discovered that Halfmile's pdf maps of the Pacific Crest Trail also use this scale, have a 1km UTM grid on them, and are a great match with this tool. The Philmont Scout Ranch's sectional maps are also a good match with MAPTOOLS PRODUCT -- MAP RULERS Ten rulers covering the common map scales used by the USGS, Forest Service, and BLM. These rulers can be used to measure or plot latitude/longitude coordinates, UTM/MGRS/USNG coordinates, and to measure distances in either meters or miles. On the front side, the rulers have minutes and seconds on one edge and decimal minutes on the other edge, allowing you to use either notation. MORE DETAILS ABOUT THE UTM COORDINATE SYSTEM More details about the UTM coordinate system. The Universal Transverse Mercator projection and grid system was adopted by the U.S. Army in 1947 for designating rectangular coordinates on large scale military maps. UTM is currently used by the United States and NATO armed forces. With the advent of inexpensive GPS receivers, many other mapusers
WHY USE UTM COORDINATES The UTM coordinate system offers the following benefits: UTM Provides a constant distance relationship anywhere on the map. In angular coordinate systems like latitude and longitude, the distance covered by a degree of longitude differs as you move towards the poles and only equals the distance covered by a degree of latitude at theequator.
DIFFERENCES BETWEEN MGRS AND USNG MGRS allows you to reference an entire 100,000m square area, e.g. 10S EH, whereas USNG suggests at least two digits and thus the largest area that can be described is a 10,000m square, e.g. 10S GJ 0 4. The USNG does not specifically prohibit 100,000m truncation, but instead omits it from the standard document, whereas the MGRS standardToggle navigation

Our products are in daily use by many federal, state, and local land management agencies, along with military, law enforcement, and search and rescue teams around the world. RECENTLY WE HAVE BEEN GETTING MORE INQUIRIES ABOUT USING OUR TOOLS WITH USNG (UNITED STATES NATIONAL GRID) COORDINATES. All of our tools that measure UTM coordinates, will also measure USNG. The USNG grid system is built on top of the UTM coordinate system. They will also work with the Military Grid Reference System, which is very similar to USNG. Learn more about USNG with our USNG Tutorial.
CUSTOM MAP RULERS FOR ANY MAP SCALE MapTools can now make you a customized map rulerfor any scale map.
STOCK TOOLS
MapTools produces grids, corner rulers, roamers, and rulers to assist with plotting or measuring positions on many different map scales. Tools for both UTM/MGRS/USNG and Latitude/Longitude coordinates areavailable.
If you are already an experienced map and GPS user, you have come to the right place to get professional quality plotting tools. You'll want to jump directly to the pages describing the tools. UTM/MGRS/USNG Tools & Lat/Lon ToolsTUTORIALS
If you are a new map coordinate or GPS user, you will want to visit the tutorial pages for an introduction to geographic coordinate systems. Or check out my book, "Using UTM Coordinates withyour GPS"
MAPPING & NAVIGATION ACCESSORIES In addition to the coordinate plotting tools designed by MapTools, I sell other useful products that I personally use and find to be useful additions to my navigation and mapping tool kits. TRADITIONAL V.S. MODERN NAVIGATIONAL TOOLS I've run across a lot of people who are convinced that traditional navigation skills using a map and compass are the only way to go. They are not ready to trust a GPS receiver. To them, I would offer thefollowing analogy.
> Just because your car could breakdown doesn't mean you should always > walk. It does mean that you shouldn’t forget how to walk. A GPS receiver is hands down the fastest and most accurate way to determine your location on a map. It will work in many conditions where using a compass to find your location is difficult or impossible; such as darkness, and reduced visibility environments. Like most tools, to make good use of a GPS receiver some specialized knowledge is required. A GPS receiver is no substitute for good traditional navigation skills. You still need a good map, along with the skills to use it. Most likely, you will still want to carry a compass and the knowledge to use it. The tutorials on this site and the classes I teach, strive to find a balance between traditional skills and modern ones. If you are a GPS "refusenik", I hope you will reconsider. WILDERNESS NAVIGATION CLASS I have retired from teaching a Wilderness Navigation Class at West Valley College, in Saratoga, CA after more than a dozen years of teaching the class. Most of the class materials and presentations are still available. I'm slowly working to get them better organized and put the missing stuff online as well. Here are the slides from my talk titled "Backcountry navigation in the twenty-first century. – Should I still pack my Compass?" given to the Peak Climbing group of the Loma Prieta Sierra Club, on May 8th 2018.
