My annual subscription to TNP is coming due. Actually two subscriptions for two states; NM and NC. A very pricey set.
I am not familiar with CalTopo but I love USGS Topographic maps. 1:24,000, 1:62,500 and 1:250,000 are all part of my routine viewing and use.
Is there anyone out there who has knowledge of both products and share some advice?

    our SAR team used TNP for years before switching to sartopo. No
    comparison. We are massively glad that we moved. I don't think
    caltopo/sartopo has any USGS other than 7.5', which is very very rarely a
    minor bummer but has never made us wish we were still using TNP!

    Also to clarify, I'm not on caltopo/sartopo staff but used to be for a
    short time several years back. I'm sure the current support staff is
    pretty limited in what opinions they can give, but objective feature
    comparison should tell the story nicely.

    Thank you that is the kind of reply I was looking for. We will see if anyone else speaks up with comparisons.

    Please visit the map page at caltopo.com and give the program a try. It's free to use for as long as you'd like. Subscriptions offer some additional features if you find that you need them. Our Getting Started article will help you to get a feel for how to use the program. We offer a comprehensive collection of base layer option that cover many types of uses, but you'll get a lot more out of using them for a bit than from me trying to explain them!
