You can create your own maps by adding several other layers on top of the Google Map using the Google My Maps feature. Once you create your custom maps, you can share it with your team or anyone. You can view it on any device. In this post, I will show you how easily you can create your own maps using Google My Maps.
How to create and share custom maps with Google My Maps
First of all you need to be logged into Your Google account using your Gmail.
Let’s assume you’re going to organize some survey in several geographically dispersed locations. It will make your job easy if you can map the survey location and include all the attribute of the locations on the map. You may also need to communicate the survey plan to your staff.
To create your map, go to Google My Maps and, click “CREATE A NEW MAP” button. You can also access this feature through Google Maps menu, Your Places > Maps > Create Map. Now you have created a new map, and it will automatically save on your Google Drive.
Rename your map and add a brief description
To rename your map, click on “Untitled map” and provide your map title and description in the relevant fields of the popup window.
You can organize your map features with map layers. For example, you can put your survey locations into one layer and accommodations into another layer. You can name these layers, add different icons and colours etc… You can have 2000 lines, shapes or places in a layer and a map can have up to 10,000 lines, shapes, or places.
You can add your places by searching for locations or drawing them directly on the map. To draw a place, click the marker icon and again click on the map where you want to add the place. Now you can rename the marker add a description too.
If you have set of coordinates (latitude and longitude) as a spreadsheet or as a CSV file, you can import them to a layer in Google My Maps. Those coordinates are added to the map with separate marker for each coordinate.
