Author Topic: How to: Aerial map with topo lines (Read 7441 times)

Joseph · « **on:** February 02, 2014, 10:15:48 AM »

In case anyone finds it useful, here is how you can display topographic lines on top of an aerial.

The following link starts Gmap4 (I am the developer) and if you zoom in until the scale in the lower left says 500 ft then you will see topo lines on the Google aerial for anywhere in the U.S.

http://www.mappingsupport.com/p/gmap4.php?ll=38.640824,-83.571710&z=5&t=h,Topography_lines&rest=http://services.nationalmap.gov/ArcGIS/rest/services/USGSImageryTopoLarge/MapServer?name=Topography_lines&layers=34,35&transparent=true

To start zooming in to your area of interest, try Menu ==> Search to get close and then zoom/pan. To manually zoom, use your mouse wheel or the sliding control near the upper left corner of the map.

To turn the topo lines on/off, click the button in the upper right corner of the map then scroll down to the Overlay section and click "topography_lines".

The topo line data comes from a GIS (Geographical Information Service) server run by the feds. That GIS data displays the topo lines on top of any basemap.

The Gmap4 homepage has a FAQ, examples, quick start info (in the Help file) and more to quickly get you up to speed.

Gmap4 default map: http://www.mappingsupport.com/p/gmap4.php (does not include GIS topo line overlay)

This thread would be a good one to sticky so it can be easily accessed, any moderators want to do it.

Thank you very much

Thanks again for all the kind words.

Today I traded email with the USGS and asked if they have similar topo line data I can display when the user zooms out 1 or 2 levels. Alas, they do not. I pointed out how well received their topo line data is in forums like this one and recommended they provide topo line data for the next two broader zoom levels. Hopefully that will happen at some point.

The ability to see topo lines on aerials got such nice reviews that this feature is now built right into the program. From now on you do not need any special Gmap4 link to use this feature.

For more info please see the “What’s new” page:

Cool program! Is there a way to see where natural water springs are? I have seen them on maps so I would figure you would be able to see them here?

Here is a topo map with a number of spings shown.
