How to: Aerial map with topo lines

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/gma...opography_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.

Thank you Joseph, that is helpful.

 

Odd. Just tried and it works for me.
I'm using Firefox v.26 on a PC

Did you zoom in so the scale in the lower left said 500ft?

What an awesome application. Thank you very much for the link. On my screen the T8 layer shows all my state forrests. is there a way to layer this over the hybrid screen to show the state lands over the hybrid screen?

 

That was freaking awesome! Thank you

 

Thanks for the kind words.

Both t8 and h (hybrid) are solid layers. Thus you cannot overlay them.

However, if you can find a GIS server that shows the location of those state forests then you can most likely make a Gmap4 liknk that will display that state forest data as an overlay on top of any basemap that is built into Gmap4.

WOW... outstanding job! I just bookmarked the gmap4 site and printed out some places I hunt.

 

AWESOME! Thanks for the link!

 

Although there is not much use for topographic maps on my property, this will help me greatly with WMA's in my area.

Great job - Thank you!

 

I see you are in MN. I grew up in Anoka MN but moved to the greater Seattle area in '77. The winters would likely kill me off if I had to move back.

I made some maps for MN and a few other states.
Start here:
Gmap4 - Share Enhanced Google Maps - Example maps

Look down just a bit to the section titled "Other recreation maps produced by MappingSupport" and click the link at the end of that paragraph.
Then scroll down to the MN maps.

Enjoy!

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.
