CAD Overlays in Hammer Missions


Overlaying plans or CAD drawings onto a map or site plan is not a new concept and has been used in the construction industry for quite some time, here at Hammer Missions we have taken that one step further...

By using Hammer Missions you can now overlay plans, be it floor plans, CAD drawings, road maps, or any other type of plan, over the top of your captured and processed 2D drone data.

This short tutorial will take you through the steps to get your overlays placed on top of your existing captured 2D drone data.

There is now an option to produce both 2D and 3D mapping data when you process your imagery.

CAD Overlay

In this example, we will be using a capture of Newark (as shown in the title image). This concept can be used for any type of 2D map, from a large open space to a construction site.

As long as you have the correct overlay for the area or site you are planning the overlay will work correctly.

1: Select your captured 2D processed map in Hammer Hub projects.

2: Make sure you have your overlay to hand as you will need it for the next stage

3: With your 2D map open in Hammer Hub select the overlay icon in the top right-hand corner, highlighted below in red.

4: A new pop-up will now open where your overlay details will need to be inputted.

5: Select your overlay using the select file option. This will now open your finder or explorer for you to select your file.

Once you have selected your file press continue.

6: The next step is to configure the geographical boundary in which your overlay will sit.

The bounding box represents a rectangle in geographical coordinates where the file should be placed. The rectangle is constructed from the points at its north-east and south-west corners

These boundary coordinates can be taken from google maps.

In our case for our Newark overlay, the coordinates from google maps were as follows:

North: 40.773941, East: -74.12544

South: 40.712216, West: -74.22655

These coordinates can then be inputted into the relevant dialog boxes as shown below:

Once you have inputted the correct coordinates press continue.

7: Now all the relevant data has been added you can press upload to add your overlay to the 2D map.

8: Now the data has been uploaded you will see that the overlay fits perfectly over the original 2D map.
