Mach9 Objects – Digital Surveyor

Overview

When looking at a template, there is a column called the Mach9 Object. These are the different features that Digital Surveyor’s automation will look for and pick out of a dataset during an automated survey. If a user wants to make sure the features are placed on the desired layer during the automation request, they will want to ensure these are properly mapped ahead of time.

Current Mach9 Objects

Layers can be associated with the following Mach9 Objects. Ones with P next to them are Point objects and L are Line objects:

ADA Ramp	P	Pavement Arrow	P
Back of Curb	L	Pavement Message	P
Bike Rack	P	Pavement Symbol	P
Bollard	P	Pedestrian Crossing Light	P
Bottom of Curb	L	Phone Booth	P
Catch Basin	P	Pipeline Marker	P
Concrete Barrier Bottom	L	Planter	P
Concrete Barrier Breakline	L	Pull Box	P
Concrete Barrier Top	L	Rail Terminal	P
Crosshatch Centerline	L	Rumble Strip Centerline	L

What if a Mach9 Object is not associated with a layer?

The feature can still be requested by an automated survey. When viewing the survey in Digital Surveyor’s viewer, the features will appear in an unassigned class.

What if a Mach9 Object is associated with multiple layers?

Digital Surveyor may view this as a conflict during the automation process, so the features could appear in an unassigned class. To correct this quickly tab through all unassigned Mach9 Objects and assign them the proper layer.

The exception is if the user has the layers set up to use additional attributes to make each layer unique such as a layer for white paint stripes and a layer for yellow paint stripes. In the example below, both share the Mach9 Object of Striping but we can specify a unique paint color to narrow down the classification.
