The Location Button

10 Jun

Most everyone who has ever clicked on a thumbnail on steamlocomotive.info has seen the page below:

In the upper right hand corner, there’s a button labeled “Location”. If you know, or think you know the location of this locomotive, then you’re ahead of us and clicking that button will provide you with a choice of two convenient ways to send us the coordinates so we can add a map for the locomotive. So click the button and you’ll see:

Yes, I did say two ways, and there are three buttons. The Mobile Device method is currently disabled while it is being rewritten to work better and not annoy visitors so much. We can begin by clicking “Use Google Maps”. This will bring you to a page that looks like this:

We call this the geolocation window. In the case of this locomotive, we do not know where it actually is. The red marker in the center of the map is located at the approximate geographic center of Neuquen, Argentina, the town in which the locomotive is located. You can zoom in and out using the on-screen controls, or using the scroll wheel on your mouse. You can drag and drop the marker by pointing to it with your mouse and holding down the left mouse button. You can then drag the marker anywhere you like. When you release the mouse button, the marker will drop, and at the bottom of the screen you’ll see Google Maps API’s best guess as to the actual address where the marker landed. At the top, you’ll see the latitude and longitude of the marker. Once you find the locomotive, zoom in and place the marker as close to the locomotive as possible. Once you’re happy with the placement, click Submit and the map will be submitted to the Editors for approval. If you cannot find the locomotive, just click Cancel to be taken back to whence you came.

The next method to supply us with map coordinates for a locomotive is labeled :

This one is simple, convenient and works quite well. When you take a photo with you Android or Apple iPhone there’s an excellent chance that your phone embeded the latitude and longitude of the camera’s location in the photo itself. And we can read that, and use the information to make a map. So click this button and you’ll see the following:

Click on Choose File and find the photo you want to submit. Add your email address, and click submit. You’ll get one of two responses. If your image has geographic coordinates in its meta data, you’ll see a message page that looks like this:

The photo you submitted DID have GPS coordinates and a map will be addeded. If the photo you submitted didn’t have any GPS coordinates it will look like this:

Hope this all proves useful.
