Tracing from satellite images: simple road and path additions
1) Go to http://www.openstreetmap.org/ and use the zoom control on left side of the screen to zoom in on the area in which you want to make updates/edits.
2) Click on "Edit" tab - the satellite view opens. Choose the "Edit with Save" option unless you are an experienced OSM map editor.
3) Identify the street(s) or path(s) you want to add to the map. Content already included in the OSM database is overlaid on top of the satellite image.
4) Use the drawing tool to trace a path along the street or path you are adding. Click once for each point and double click to end your path. If you make a mistake click the back arrow at the bottom left of the screen or press the “z” on your keyboard. You can also press the “Esc” key to clear all the points.
Tip: Click the check box icon in the lower left to open map options including the background.
Choose the OSM-Cycle Map or the Open Topo Map for a topographic map background.
Existing features can also be moved or edited in this view. Use the details box in the lower left to classify the feature (primary road, secondary road, residential road, etc.). If you are adding a path not intended for automobiles, click the car icon to toggle to different classes (biking, pedestrian, boating, skiing, etc.). You can also use this tool to add a name to the feature if applicable.
5) When you click off your new path, click the Save button in the lower right to upload your changes to the OSM server. It may take 1-2 days before it shows up on the main map for everyone to see, so please be patient.
1) From MotionX-GPS, email the track you wish to add to OSM to yourself and save the attached GPX file to a directory on your computer.
2) Log into OSM and click on the “GPS Traces” tab at the top of the page. Browse for your GPX file location, provide a brief description, then upload. After uploading it may take up to several hours for your track to become available (depending on server traffic), but often it’s available within a few minutes. Select Edit link. This will overlay the track on a satellite view.
3) Trace over the track, clicking point-by-point to capture all the detail. Use the details box on the bottom left to define the track type. Click off the track and it will automatically be uploaded to the OSM database. It may take 1-2 days before it shows up on the main map for everyone to see, so please be patient.

UTM Zone Lookup
This utility finds Universal Transverse Mercator (UTM) zone and its central meridian for a given geographic coordinate. by APSalin
The Military Grid Reference System (MGRS) is a standard used by militaries for geo-referencing and locating specific areas on the surface of the earth. The MGRS is similar in nature to the UTM (Universal Transverse Mercator) grid system, and in fact was derived from UTM, but the labeling convention used by MGRS follows a different set of rules. MGRS is used between the latitudes 84°N to 80°S; the polar regions are based on the Universal Polar Stereographic system.
An MGRS coordinate, or grid reference, describes a square area of 10x10 km, 1x1 km, 100x100 m, 10x10 m or 1x1 m, depending on the precision of the coordinates provided. All points within that square share the same MGRS coordinate (note the grid reference does not describe a single point on the earth's surface like a standard latitude/longitude coordinate). The total number of characters must be 7, 9, 11, 13, or 15, respectively, depending on the desired precision (additional digits define higher precision).

uTrack - GPX Report Generator
uTrack is online utility for generating track reports from GPX files. The track is shown on Google Maps or AMaps. Elevation profile, Elevation vs. Distance and Elevation vs. Time are displayed in user friendly graphs. Total ascent and descent are calculated as well. Speed vs. Distance and Speed vs. Time are also plotted. Then you can easily export your report to a PDF file.
GPS Visualizer- Do-It-Yourself Mapping
GPS Visualizer is a free, easy-to-use online utility that creates maps and profiles from GPS data (tracks and waypoints, including GPX files), street addresses, or simple coordinates. Use it to see where you've been, plan where you're going, or visualize geographic data (business locations, scientific observations, events, customers, real estate, geotagged photos, etc.).
GeoLadders - Create Routes, Rides, Races using GPX files from MotionX-GPS.
GeoLadders is a GPS based website offering detailed route information for various sports such as mountain biking, road biking, walking, running, etc. GeoLadders hosts 'free' weekly, monthly, and yearly amateur competitions based on a user's completed routes. Results are dynamically displayed as a ladder (competitors listed in order of their rank/points). Routes in Geoladders are assigned a point value based on distance, ascent and difficulty, every route ridden adjusts a riders ladder rank. It's motivating, healthy and good fun! Create your own tracks, play them back and share them with friends.
To upload your GPX track to GeoLadders do the following:
Google Earth lets you fly anywhere on Earth to view satellite imagery, maps, terrain, 3D buildings, from galaxies in outer space to the canyons of the ocean. You can explore rich geographical content, save your toured places, and share with others.
Drag and drop your GPX or KML files created with MotionX-GPS to plot your tracks and waypoints in Google Earth. Another great benefit for flying - you can see your track rendered in 3D like the screen shot below.
When you drag your file into Google Earth you will see this dialog. Just uncheck, "Adjust altitudes to ground height" to view the track in 3D.
Where's the Path? For MotionX-GPS users in the UK, upload GPX files to chart your journey on Ordnance Survey® maps. The same path is plotted on an adjacent Google aerial map and includes (lat,lon) coordinates.
HoudahGeo - Geotag photos: One stop geocoding for the Mac
Use MotionX-GPS to record a track, take photos with any digital camera during your track and then use HoudahGeo to geotag your photos along your track. Try out the free demo.
Below is a sample track from HoudahGeo (track and photos recorded while walking on the top level of a parking garage). Clicking the pink camera icons would display the photo taken at that location.
Great Circle Distance and Bearing Calculation
This utility uses WGS84 approximation to calculate great circle distance and bearing between two geographic points. by APSalin
This utility calculates destination geographic coordinate based on the distance, bearing and starting geographic coordinate, for commonly used Earth ellipsoids. by APSalin
Identify Lat Lon Coordinates
Identify latitude and longitude coodinates on Google Maps with just web browser -- eliminates the need for Google Earth for this function. Create a single waypoint or an entire path. Can use the export tool to generate files in the following formats: CSV, TXT, TAB, BLN, DXF, KML, GPX, SHP
Convert a GPS file to plain text or GPX
This form reads a tracklog or waypoint file (in a recognized format) or plain-text tabular data, and converts it to an easy-to-read tab-delimited or CSV text file, or to a GPX file.
Convert your GPS data for use in Google Earth
This form will import your GPS data file, or plain-text data (tab-delimited or CSV), and create a KML file that you can view in the Google Earth application or import into Google's "My Maps" system.
