## Topo Reader Description
Download all available USGS topographic maps and import Geospatial PDF maps for off-line use at full undistorted resolution.

Topo Reader is designed for road trips, camping, hiking, exploration and geographical history. Map images are accurately center aligned regardless of datum and placed on top of Apple's map kit for easy referencing and intuitive touch navigation.

Topo Reader can install for use 422,664 U.S. Geological Survey current and historical topographical maps describing the topography of every region and island territories of the United States of America. Historical versions date as far back as year 1879. Install a map quad by pressing and holding a point on the reference map and discover the maps available at that location and the unique names given to every quad by the cartographers.

Local and national park services offer PDF maps from their web sites.  Even aeronautical sectional maps with embedded geospatial metadata that you can download in installed into Topo Reader.

Easy see all your installed maps by zooming out and they all become a colorful violet and partially transparent so you can spot your map. Installed maps are managed in a table format which can be sorted by name, distance, and scale. Multiple versions of the same map can be stacked on top of one another and made visible or hidden using two finger swipes.

## Topo Reader Reviews in United States

### *---- "Premium isn’t permanent"
I paid for premium, and now I can’t use it anymore!!!
-- nickname 7777777, 2020-09-21

### ***** "Real estate"
Great
-- hobby11, 2019-12-17

### ***** "Great App"
Very useful!

### ****- "Good app and cheap!"
Seams to work well. Recommend the 3 month option.
-- ralph asmus, 2017-06-28

### ***** "A brilliant topo app!!!"
This is a marvelous free topo-map reader that's chocked full of powerful special features not found in many similar but expensive paid apps. The interface is brilliantly designed for maximum control and flexibility, and the extensive integrated help file makes this app a joy to use. The developers are to be congratulated for providing the public with free access to historical USGS topo maps through such a logical, powerful, and appealing tool. This topo reader has quickly become indispensable to me in planning hiking and climbing trips. I absolutely LOVE this app and would give it 10 stars if I could. ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
-- Summit14er, 2015-06-08

### *---- "Ads make it unusable even to try"
This seemed like an amazing app at first. I thought for sure I'd look into the paid version once I'd reached my maximum # of maps. But I couldn't even download the 3 maps I needed to look at the trails I'm hoping to walk on, because every time I scroll to find the map location, a 15 second ad starts playing. The app is unusable as a trial. It seems to have high potential, but I'll have to look at other apps instead since the ads in this one make it impossible to view the maps (which are available free on USGS website.)
-- dina_g, 2015-05-12

### *---- "Impossible to Use Due To Advertisements"
When the "in-app advertisements" suddenly pop up, they take up the entire screen.  This happens so frequently, it makes the app pretty much useless for its intended purpose.  I'm okay with ads in "free" versions of applications, but this near-constant full-screen takeover defeats the purpose of a mapping application.
-- PilotWesley, 2015-03-30

### ***** "BEST APP EVER!!!"
This is the greatest app. Used it too explore the my local mountain side. While I was looping the mountain side I found some suspicious wooden boards near the base of the mountain. Then I found an abandoned gold mine. I went in and found what appears to be gold flakes. I am planning to stay here quite a bit. Most people don't use these maps but I have found some maps that still have locations of old mines. After this exciting adventure I am heading to Nevada to look for silver mines. I would highly recommend this app.
-- qpearson, 2015-01-26

### *---- "Бесполезная"
Обычный просмотрщик карт! Никаких Топокарт нет
-- Espasio, 2014-12-23
