Property Line Maps - Works online and offline on your cell phone

Sample - Completed Order

When an order is completed the customer receives an e-mail. That email includes an online map link that starts the GISsurfer software and displays a map showing the customer's approximate property lines and corners. The email also includes a GPX file with a waypoint at each approximate property corner. A sample of that e-mail is below. After that sample e-mail is a link to a sample of the kind of GPX file that will be sent with the email.

Sample e-mail

Hi Steve,

This email completes your order from or Please keep in mind that these coordinates and property lines are approximate and are not survey-grade.

Below is the link that starts the GISsurfer software and displays your map. This link uses our exclusive map-in-a-link technology. If you click/touch a corner, then you will see a popup that has the corner number and the approximate coordinates. This email also includes tips for areas with spotty cell service or no cell service.

This map link will work in most browsers and on most devices, from smartphones to desktop computers. If your email program does not display the map when you click this link, then simply copy the entire link and paste it into your browser address bar. And if your email program trashes this long link then please let me know and I will send it to you by a different method.||description=plm2||label=on||line=on||44.569128,-85.134233^1||44.569105,-85.12916^2||44.565483,-85.129117^3||44.56551,-85.134168^4||44.569128,-85.134233

=== Smartphone Tips ===

1. If there is good cell service on your land:
    A. Open the map link shown above. You will be looking at your approximate property lines and corners displayed on an aerial photo.
    B. Turn on the geolocation feature by tapping Menu ==> My location. The map will center where you are standing. The symbol at the center of the map will follow you as you move.
    C. Walk until that symbol is on top of a property line or property corner.

2. If there is spotty cell service or no cell service on your land then these tips will help:
    A. As you are driving to your land, stop someplace where there is cell service and you can open the map link we sent.
    B. Open your map link and zoom in on your property to the zoom level you are going to use as you walk around.
    C. Drag the map around on your screen so you cover all of your land. This part of the aerial photo is saved in your browser’s short term memory.
    D. When you arrive at your land, turn on the geolocation feature by tapping Menu ==> My location. The map will work even in areas where there is little-to-no cell service as long as you (1) do not change the zoom level or (2) go outside of the area you covered in step ‘C’.

If the above method does not seem to work for areas with spotty cell service or no cell service, then here is an alternative.
    A. Open the map when you are someplace with cell service.
    B. Tap the basemap button (next to the Menu button).
    C. Select “All white basemap”
    D. When you arrive at your land, turn on the geolocation feature by tapping Menu ==> My location. As you walk around you can zoom in as much as you want as you get close to a corner.

3. iPhone users with iOS 14 and later.
    A. Go to Settings ==> Privacy. Make sure “Location services” are ‘on’.
    B. Next, tap “Location services” and scroll down to “Safari websites” and make sure it says “While using”.
    C. Tap “Safari websites” and make sure “Precise location” is turned ‘on’.

4. Android 11 (or later) users:
    A. Go to Settings ==> Location make sure it is ‘on’.
    B. Tap “App permissions” ==> Chrome - make sure it is set to “while using”.
    C. Go to Settings ==> Battery and device care ==> Battery - Power saving mode must be ‘off’.

5. Older versions of Android.
Open Settings and go to the screen where you turn location services on/off. If you see a setting for location method (also called "mode") then set that to "GPS only". If you use the so-called "High Accuracy" setting then data from cell towers can degrade the more accurate data from the satellites.

=== Online Map Tips ===

If you see an error message when you turn the geolocation feature on, then place your phone in an upright position where it has a good view of the sky. Your phone will download some data from the satellites and after a few minutes the geolocation feature will work.

To change the scale at the bottom of the map from meters to feet, click/touch Menu > Change scale.

If your device is online then you can see contour lines on top of the aerial, Tap the basemap button (next to the “Menu” button) and scroll down to the “Overlay” section. There are two contour overlays. Tap them both to turn them ‘on’. That data may take a few seconds to appear on the screen. Tap those overlay names again to turn the contour lines ‘off’.

=== GISsurfer Tips ===

Your online map is displayed by GISsurfer which is a general purpose web map that anyone can use for any non-commercial purpose. In addition to displaying property line maps, GISsurfer has many built-in features. There are also various GISsurfer map links you can open which display multiple layers of GIS data related to recreation and disasters. To learn more, please visit the GISsurfer website:

=== Standalone GPS Tips - Garmin etc ===

There really is no good reason to use your property line map via a standalone GPS device (Garmin, etc) instead of a smartphone. Both have about the same accuracy and the phone will display a high resolution aerial and be *much* easier to use. However, if you really want a GPX file please ask and one will be provided.

Thank you for your order and I am happy to answer questions.
