It's actually very easy to get started, but there are some powerful features that you might not be aware of. After reading this, you should have a better understanding of what GPS Visualizer can do and how you can take advantage of it. For most of the examples on this page, we've created very simple JPEG maps. They're not very fancy, but this document isn't about spectacular maps, it's about massaging data into a mappable format. Unless otherwise noted, all the information here also applies to creating Google Maps, Leaflet maps, Google Earth files, etc.
Once you have a nice, clean data file, you can do anything you want with it. All you really need is a collection of coordinates, or even just one pair of coordinates; adding a "name" to each point is not necessary, but very helpful and it lets GPS Visualizer know that you're uploading waypoints rather than a sequence of trackpoints.
For this example, we'll use the tallest Cascade Range volcanoes in southern Washington and Northern Oregon. The easiest way to organize your data is using a spreadsheet, like Microsoft Excel. On the left, below, is a screen shot of an Excel worksheet, and on the right is the same data in simple, comma-separated format. To make a map from data like this, just cut and paste the data from Excel or your text editor into the text area on GPS Visualizer's map form.
When you copy data from Excel, it gets pasted with tabs, which will work fine but might look strange. Go ahead and try it using the data in the box above. After clicking the "Draw a map" button, the resulting graphic should look similar to the map on the left.
Here's the most important thing that can be emphasized about creating plain-text data files for GPS Visualizer: Having a sensible "header row" above your data is VERY important. The order of the fields is NOT important. Spaces between fields and capitalization of the header row aren't important either. Include as many or as few fields as you want; as long as a waypoint contains information that might let you plot it on a map, GPS Visualizer will try.
Now, let's add a "description" field to each point usually abbreviated as "desc". For now, we'll put the full name of the mountain, along with the state it's in. So Rainier's description is "Mount Rainier, Washington. We'll also add a field that contains the height of each mountain. We'll call it "alt" to keep it short, but you could also use "altitude" or "elevation.
Click here to pre-fill the map form with this data. There's something very important to notice about this comma-separated data: the items in the "desc" column MUST be enclosed in quotes because there is a comma inside each description. Without the quotes, everything would be shifted back one column, and the altitude of the first two points would be listed as "Washington"!
The nice thing about storing your raw data in a spreadsheet like Excel is that you can manipulate the fields as needed. This is especially helpful for the description field. Let's say we want to display the height of each mountain on the map. All we have to do is concoct a simple Excel formula that reads the "alt" field and adds it to the end of the existing "desc" field.
Since the column with the formulas in it will need to be called "desc" in order for GPS Visualizer to recognize it, we'll rename the original "desc" column to "full name," which GPS Visualizer will ignore.
In the screen shot below, you can see the formula in cell C2 laid bare for the world to see; in cells C3 through C5, the results of the formula are visible.
Maybe we should have just put the altitude by itself in the description field; it's getting a little messy. Oh well, there's no harm in experimenting. Note that if your output format supports HTML in waypoint names or descriptions i.
