Installing and Running the CalTopo Offline App - Windows
To install the CalTopo Offline App you will need:
- CalTopo App
- CalTopo map data for your desired area
- Java Standard Edition JDK
Download and install the CalTopo app
Decide whether you want to install CalTopo Offline on your computer's hard drive, a thumb drive or an external hard drive. Depending on how much map data you plan to download, it may not fit on your computer's hard drive. If you're not sure, start by installing it to your computer's hard drive now, it can be copied to another drive later if needed.
Sign-in to your GIS account on CalTopo.com.
Click on your account name at the top of the left bar, then the "Offline Access" tab, or go directly to http://caltopo.com/offline/app.
Click on "fresh install" and download the caltopo-offline.zip file to your computer.
In File Explorer, go to the Downloads folder and right-click "caltopo-offline.zip" and click "Extract All".
Specify the drive where you want to install CalTopo (e.g. "C:\") and click "Extract"
Download the map data.
CalTopo Offline is installed without any map tiles. To download the map tiles for your desired area, go to http://caltopo.com/offline/data.
The red-shaded areas indicate areas where offline maps and data are available. Hover the mouse over a portion of the red-shaded areas and a solid-red, one degree square will appear.
Click on the solid-red square of the block that you would like to download. On the right side of the page, a list of available data for that one degree square appears.
Download the data files by clicking on the size of each file. Its important that you download all of the files.
Move the files from your Downloads folder into the caltopo > data > tiles folder (e.g. C:\caltopo\data\tiles).
Repeat the above steps for additional one degree blocks as needed.
Install Java Standard Edition JDK
Go to http://www.oracle.com/technetwork/java/javase/downloads/index.html, click on "Java Platform (JDK)".
to download the installation file, cllick "Accept License Agreement" and choose the appropriate JDK for your Windows Operating System ("Windows x86" for a 32 bit computer and "Windows x64" for a 64 bit computer). If you are unsure whether you have a 32 bit or 64 bit computer, the 32 bit (x86) will run on either type.
Once the installation file is downloaded, open it to run it. Accept all of the default installation options.
CalTopo Offline is essentially the same program as caltopo.com. Whereas caltopo.com is hosted by a web server in the Internet cloud, CalTopo Offline is hosted by a local web server on your computer. In both cases you use a web browser to interact with the server.
Therefore it takes two steps to run CalTopo Offline:
Start the CalTopo Offline server:
In File Explorer, open the "caltopo" folder (eg c:/caltopo) and double-click on the "CalTopo-Offline" file.
You should see a black command window open.
You can minimize this window, but don't close it. The server is now started and you can go to a browser to access the functionality.
Open a web browser (Chrome is recommended). On a new tab, go to http://localhost:8080.
The server may take some time to get up and running. If initially you get a web page error (e.g. a “This webpage is not available” or "This site can’t be reached" message), then the local web server may need more time to get fully started. Wait for a few seconds and refresh the page.
The first time you bring up the CalTopo Offline server, or after updating Java, you may get a Windows Firewall message.
Click "Private networks" and "Allow Access" to allow the CalTopo Offline webpage to talk to the CalTopo Offline server on private networks (to include on your own computer).
When you are finished using CalTopo Offline:
- Close the CalTopo Offline tab in your browser
- Click on the black command window that opened when you started the CalTopo Offline server and click the "X" to close it.
If multiple computers are on the same Local Area Network (e.g. connected to the same router), each of the computers can connect to the CalTopo Offline server running on one of the computers. To do so, each computer opens an web browser and goes to the Server Address displayed in the black command window (eg. http://mycomputer:8080) for the CalTopo Offline Server.
To update your version of CalTopo Offline, download a new version of the cal.jar file to your caltopo folder.
Click on ??? to http://caltopo.com/offline/app
Click on "JAR only" and move the cal.jar file from your Downloads folder to your caltopo folder.
