Location Integrations


CalTopo allows you to track a number of devices that report your location to a map.

Below is information about products, systems, and devices that are not CalTopo products. We include information about these products as a service so that you can better integrate these devices with CalTopo. We try to keep this up to date and detailed enough so you can get these devices to work with CalTopo. Unfortunately we cannot do very much to fix, improve or debug the products below. We will help in any way we can to get these products to work for you in CalTopo but if you believe your product is defective, has a bug or some other problem associated with that device, please contact their customer service.

Garmin inReach Setup

CalTopo offers integration with all inReach devices including the popular inReach mini and other devices.

CalTopo uses the inReach Personal Connect (IPC) to receive this information from Garmin. Use of the IPC requires a professional account for your device. Garmin allows one or more devices on a single Professional plan.

More information about Garmin Professional plans can be found here. If you are already active on a Personal plan, you can switch your account to a Professional plan by following Garmin's instructions for switching an inReach subscription to a Professional Account.

The next setup steps are done in Garmin's interface and require an active device with an active professional plan (see above). To begin, navigate to Garmin's inReach portal and login.

You'll be brought to the main page of Garmin's account system. Sselect Settings (circled with an orange 1 on the below image) and then navigate to Portal Connect (circled with an orange 2 on the below image). Once on this page, you'll see the OUTBOUND Portal Connect. Copy and paste the URL with the connect key in the URL field.

Once you are on the portal connect page, look for the outbound setting section. Copy and paste the URL with the connect key there.

Turn on the outbound connection (click on the gray off switch and it will turn green and display the word on as shown above). Copy and paste the copied URL from the details dialog box into the URL field.

You can send a test message at this point to your map and it should display a dummy locator and a marker at that point. Make sure to save your settings on the Garmin site at the bottom of the page.

We'll say that one more time- remember to SAVE this setting.

At this point you've successfully linked your trackable device to the team account. Any inReach that is part of the Garmin account will appear in the Trackable Devices list and as part of the Shared Locations layer the next time that it reports its location. Garmin devices may require additional settings to push updates; typically these can be set to occur regularly, or only on demand, based on your plan and preferences.

Garmin inReach Tracking Info

Once you've configured the Portal Connect page, there are a few important things to consider regarding your inReach device. You'll need to set up your inReach tracking settings and understand how frequently the device reports its location to the satellite. This information is covered here on the Garmin website.

A crucial section to note is near the bottom of that page. InReach devices report their positions only once every four hours when stationary. This can lead to confusion during set up as the device is often stationary when you test it out.

Additional Important Tracking Information
The inReach device has a power-saving function that will change the Send Interval to 4 hours if the device has not traveled more than 100 meters (328 feet). When the device is moved this distance, the Send Interval will revert to the setting selected on the inReach device. When the inReach device is powered off, the tracking feature will be turned off as well and remain off even when the device is turned back on. Tracking will need to be started again when the device is turned back on. Updates have added a new feature that allows for the tracking on the device to be automatically turned on when the inReach is powered on. To use this feature on the inReach, Auto Track would need to be turned on in the Tracking settings of the inReach device.

Everywhere Hub Setup

CalTopo provides integration with Everywhere Hub. Additional details about Everywhere Hub plans can be found here on the Everywhere Hub website. If your team already has an Everywhere Hub account, you will use their webhook feature to integrate with CalTopo.

The next steps take place on the Everywhere Hub page. First you'll need to log into your Team's Everywhere Hub account. Then follow the steps outlined below for each device associated with your Everywhere Hub team that you want to appear in CalTopo's Shared Locations overlay.

To access the Everywhere Hub webhook, click the menu icon in the upper right corner of the screen. From the menu, select "Devices." This will lead you to a page listing all the teams and sub-teams. Click on the team or sub-team of the device you intend to add and then select the specific device. You will find the Webhooks option towards the bottom of the left-hand menu. Click this and then copy and paste the CalTopo access URL in the Export Track URL box.

In your Everywhere Hub account click the menu icon and then Devices.

Clicking the Everywhere Hub team dropdown will give you a list of devices. You will need to go to each devices webhook to add it to the CalTopo Shared Locations overlay.

In the device's menu click Webhooks

Enter the CalTopo access URL for Everywhere Hub into the Export Track URL box. Ensure that you choose "https://" from the dropdown menu at the beginning of the box.

Amateur Radio APRS

APRS can work through an iGate but this section will focus on getting local traffic using the Desktop Instance. You can get more information about local APRS on the Local APRS with Desktop page.

This section will cover the set up of Terminal Node Controllers (TNC's) and radios. There are a lot of TNC's and radios available so we can only cover the ones we have direct information about. There are also differences between how they are set up depending if you have an Apple or Windows computer. If you have set up a different system and have information you'd be willing to share with us, please email us at help@caltopo.com and tell us about your configuration.


The first device we will cover is the Mobilinkd TNC. We have used the Mobilinkd on an Apple machine. Below are the settings we used in the Mobilinkd app.

We were using the Mobilinkd TNC 4 that we had cabled to the computer. We were able to use the Bluetooth but it didn't seem to perform consistently. For the topo.properties file we had this:



You will see the Mobilinkd listed in the serial ports but since it is cabled it is the usbmodem that you want to use. The number after the usbmodem is unique so make sure you edit that number if you copy the example above.

We do have settings for a Mobilinkd that worked on a Windows machine. This is what one person used in the topo.properties file:



We didn't get to see how they set up the Mobilinkd but we assume the modem settings was set to 9600 baud rate.

Kenwood TH-D7A

We have limited information about the settings on the radio. However, we received feedback from a customer who successfully used the following sentences in the topo.properties file on a Windows machine with the Kenwood TH-D7A:

Currently, our knowledge about Meshtastic is limited. While we conducted some initial testing, we didn't achieve success. It's worth noting that we haven't dedicated extensive time to this project at this time. However, many individuals have found success with Meshtastic, so familiarity with the platform may lead to better results.

To assist you in getting started, we've compiled some useful links below. Please note that these links will direct you away from the CalTopo website.
