Put A Hole In A Polygon
To create an empty area within a polygon, you need to create two paths, one inside the other. To create the hole, the coordinates defining the inner path must be in the opposite order to those defining the outer path. For example, if the coordinates of the outer path are in clockwise order then the inner path must be counter-clockwise.
Note: The Data layer handles the order of the inner and outer paths for you, making it easier to draw polygons with holes. See thedocumentation for the Data layer.
The following example draws a polygon with two paths, with the inner path wound in the opposite direction to the outer path.

To Share A Link To The Map:
Under ‘Who has access’, select Change and youâll be given options to either leave the map ‘Specific people’ , ‘Anyone with the link’ or ‘Public on the web’.
If you choose to make your map Public on the web, youâll be able to further refine your share settings to make your map either just viewable or editable by the public.
Tip: Sharing your map with a person who has a non-Google account? Copy the map URL and change the word ‘edit’ in the URL to ‘view’ before sending â then no login will be required.
Adding A Marker Point
A custom marker point is a pinpoint that appears on the map. You can use this to add additional descriptions to an area, as well as to point map users to a location or area that isnt specified on the Base Map layer.
To add a new marker point to your map, make sure youve located a suitable area on the Base Map layer. When youre ready, select the Add Marker button in the menu below the search bar in the custom map editor.
Using your mouse or trackpad, click on an area of the map. This will bring up the marker editoradd a suitable name and description and then select Save to add it to your map.

You can also draw your own shapes onto the existing map to add detail to the existing map. While you can view a custom map in the Google Maps app for Android and iOS, you can only create it using the web version of Google Maps on your desktop.
To start, head to the and sign in using your Google account. Once youre signed in, press the hamburger menu icon in the top-left.
In the options menu, click the Your Places option.

To start, make sure youre in the custom map editor by heading to the Google Maps website and selecting the hamburger menu > Your Places > Maps > Create Map.

Make A Shape Draggable
var redCoords = ;// Construct a draggable red triangle with geodesic set to true.new google.maps.Polygon;
When enabling dragging on a polygon or polyline, you should also consider making the polygon or polyline geodesic, by setting its geodesic property to true.
A geodesic polygon will retain its true geographic shape when it is moved, causing the polygon to appear distorted as it is moved north or south in the Mercator projection. Non-geodesic polygons will always retain their initial appearance on the screen.
In a geodesic polyline, the segments of the polyline are drawn as the shortest path between two points on the Earth’s surface, assuming the Earth is a sphere, as opposed to straight lines on the Mercator projection.
For more information on coordinate systems, consult the guide tomap and tile coordinates.
The following map shows two triangles of roughly the same size and dimensions. The red triangle has its geodesic property set totrue. Notice how its shape changes as it moves north.
Draw Polygon Using Mouse On Google Maps
I need to draw polygon using mouse and mark a particular area on Google maps. The purpose is to mark an area on Google maps and then showing hotels and attractions on that area. The user will mark the hotels on Google map while creating them so the db will have their latitude and longitudes.
How can I draw the polygon and fill it with a color as background to mark the area in Google Maps? I have read the API Manual how to draw polygons? basically you would need to mark multiple points and then combine them into a polygon. But I will need to do this using mouse drag, just like drawing a shape. Kindly help me out how to achieve this.
Here is some code that achieves what you want. It supports:
- dragging vertices.
It’s undocumented, but hopefully you can see what it’s doing easily enough.
$.ready ); var isClosed = false; var poly = new google.maps.Polyline; google.maps.event.addListener ); if ); isClosed = true; }); } google.maps.event.addListener ); poly.getPath.push; });});
You just need to enable the drawing tools and add event listeners for the creation of overlay types .
A quick example of its use would be:
you can use the Google MyMaps polygon editing tools in your appplication, maybe this will be ok for you?
However if you want to implement this yourself it is basically this:
add click listener to map.

How To Use Map In Autocad Drawings
Overtime, integration between GPS Map technology and CAD Software has become increasingly advanced.; People use these integrations for a wide variety of reasons.
Sometimes they wish to have their location on their Title Block. In other instances, specifying a location can be helpful when it comes to automated lighting and elevation.
Whatever the case, the sky is the limit when it comes to bringing these maps onto AutoCAD. In this tutorial, we will learn to integrate maps in AutoCAD and work with it.
Things youll need for this tutorial:
- AutoCAD 2017 or higher
- Internet Connection
- An Autodesk 360 account
The current AutoCAD has two main forms of location setting. The first one is called From Map, and the second one is called From File.
From File used to be more practical but for our purposes, From Map is better suited to our needs. Google Maps and Bing Maps are frequently changing their UI, removing or adding features, and currently, there is no easy method to do the conversion to KML or KMZ from either of these web apps.
Note: It was once possible to do a Google Maps conversion to KML but it has become more complicated and involves the use of Google My Maps, a service which allows you to create custom location-based maps. This process in itself would require a whole tutorial.
For simplicity, throughout the tutorial we are going to be working with one area, the center building of the University of Central Florida, and its surrounding features.
