To use the Generate TLE tool, you must first create the satellite and propagate ephemeris. The Generate TLE tool computes the best-fit GP data to be used with the SGP4 propagator whose ephemeris is the closest to the selected satellite in an RMS sense. At this time, GPS Visualizer is not able to do any reverse geocoding if you need such a service, start with a Google search.Trajectory Sampling Method | Single Point Method Reverse geocoding is the process of taking GPS coordinates and converting them to street addresses.

But if you do send street addresses, only a few can be processed at once, because they all must be processed by the GPS Visualizer server itself - and it will be harder to double-check them for accuracy. (The geocoding utilities listed above in #1 and #2 will attach coordinates to your points but won't do any further processing.)īy the way, GPS Visualizer's mapper and converter will try to find the latitude and longitude of any points in your file that lack coordinates - including street addresses. Not only will the mapper or converter be faster, but you can also take advantage of features like the quantitative data form, which can colorize or resize your data points based on frequency or other parameters. If your data is in tabular format (rows and columns) and contains simple data like ZIP codes, Canadian postal codes, cities, states, or airports, the best option is to format your data with an appropriate header row and then use GPS Visualizer's text/GPX conversion utility or one of the map forms directly - GPS Visualizer has built-in databases for these types of data, so it will be much faster than having to ask Google or Bing where each point is. NOTE: If your data consists entirely of ZIP codes, Canadian postal codes, airport codes, states, or countries, use the converter described below in #3, or go straight to the map form. Your data can be in either a raw, jumbled, unformatted list, or in a structured table with a header row output is plain text but can be plotted on a map or written to a GPX file. This form allows you to geocode an large number of addresses using the geocoding API service from Bing Maps, Google, or MapQuest. If you have a large batch of addresses for which you need coordinates, GPS Visualizer's Multiple Address Locator is the solution. This utility returns a small map and a nicely formatted table of information. If you only need to find the coordinates of a single location, use GPS Visualizer's Quick Geocoder. It will be much faster and easier in the long run, because your locations will only need to be processed once. NOTE: If you want to plot addresses on a map, it is highly recommended that you geocode the points first, save the results, and THEN run the coordinates through the map form to create a Google Map, Google Earth KML/KMZ file, or JPEG/PNG/SVG graphic. GPS Visualizer offers several options for geocoding your information. 'Geocoding' is the process of converting street addresses or other locations (ZIP codes, postal codes, city & state, airport IATA/ICAO codes, etc.) to latitude and longitude, which can be entered into a GPS device or geographical software.
