Installing and Running the SARTopo Offline App - macOS

Note: SARTopo users can assume that any instructions for CalTopo also apply to SARTopo.

To install the SARTopo Offline App you will need:

  • SARTopo App
  • SARTopo map data for your desired area
  • Java Standard Edition JDK

Installation Instructions

  1. Download and install the SARTopo app

    Decide whether you want to install SARTopo 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 offline account on SARTopo.com.

    Click on your account name at the top of the left bar, then the "Offline Access" tab, or go directly to https://sartopo.com/offline/app.

    Click on "fresh install" and download the sartopo-offline.zip file to your computer.

    In Finder, go to the folder that contains the sartopo-offline.zip file (probably Downloads) on your computer. Double click "sartopo-offline.zip" to open it. The file is unzipped to a "sartopo" folder.

    For security reasons, MacOS requires you to move downloaded applications to a new location before running them. In Finder, open the "mac - read instructions" folder and drag the "SARTopo Offline" app into the "sartopo" folder above it.

    Now delete the "mac - read instructions" folder.

  2. Download the map data.

    SARTopo Offline is installed without any map tiles. To download the map tiles for your desired area, go to https://sartopo.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.

    Drag all of the mbtiles files into the the sartopo > data > tiles folder.

    Repeat the above steps for additional one degree blocks as needed.

    To keep clutter out of your Downloads folder, it's a good practice to drag the "sartopo" folder from the "Downloads" folder to your home folder.

    Once the installation file is downloaded, open it to run it. Accept all of the default installation options.

Running SARTopo Offline

SARTopo Offline is essentially the same program as sartopo.com. Whereas sartopo.com is hosted by a web server in the Internet cloud, SARTopo 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 SARTopo Offline:

  1. Start the SARTopo Offline server:

    In Finder, open the "sartopo" folder and right-click on the "SARTopo-Offline" file and select "Open".

    Your computer will ask if you are sure you want to run an app from an "unidentified developer". Click "Open".

    After the first time, you can run the app by just clicking on it.

    A SARTopo Offline console window will 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.

  2. 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.

Stopping the SARTopo Offline server

When you are finished using SARTopo Offline:

  1. Close the SARTopo Offline tab in your browser
  2. Click "Cancel" and then "Quit" in the SARTopo Offline Console

Accessing the SARTopo Offline server from another computer

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 SARTopo Offline server running on one of the computers. To do so, each computer opens an web browser and enters the Server Address displayed in the SARTopo Offline console (eg. http://My.Mac.local:8080).

Updating SARTopo Offline to a New Version

To update your version of SARTopo Offline, download a new version of the sar.jar file to your sartopo folder.

Sign-in to your offline account on SARTopo.com.

Click on your account name at the top of the left bar, then the "Offline Access" tab, or go directly to https://sartopo.com/offline/app.
