Does DeepWalk's software work with Android?

No, Android cameras do not include LiDAR capabilities.

What if I don't have my own device?

You can rent a device from us through our Phone Rental Program for $150 per week. There are also options for long-term rentals or purchasing the devices directly from us.

How much data can I store on the phone?

5GB of available phone storage is required per mile of scanning per upload. It is recommended to have 45GB of available storage to perform an entire day of data collection.

Does DeepWalk perform data collection?


There are three options for data collection. Clients can collect the data themselves, clients can us engineering partners to perform data collection, or clients can use Quality Counts, a partner of DeepWalk, to perform data collection.

Do I need cellular data for data collection?

Cellular data is not needed for data collection. After a day of scanning, connect to a WiFi location of your choosing to upload your scans.

How fast can I collect data?


Sidewalk and curb ramps can be inspected at 1.5-2 mph with 1 person doing data collection. With breaks and travel, an estimated 9 miles can be collected per day per data collector.

What is the maximum distance per scan?


The maximum distance per scan is 400 feet. There is an alert on the mobile app when it is time to start a new scan.

What is the limitation of width of view?


The limitation of width of view is 3-4 meters or 10 feet.

Data

What data does DeepWalk collect on a block or curb ramp basis?

- Max. Run Slope
- Avg. Run Slope
- Run Slope Score
- Max. Cross Slope
- Avg. Cross Slope
- Cross Slope Score
- Min. Clear Width
- Avg. Clear Width
- Clear Width Score
- Concrete Area
- Brick Area
- Deteriorated Area

How is scoring calculated?
How accurate are your measurements?

DeepWalk outperforms putting a smart level down once per sidewalk panel.

How are trip hazards collected?

Trip hazards, or vertical displacements, are not automatically collected by scanning. Trip hazard locations can be marked using a manual tag on DeepWalk's app.

Who owns the data?

The client retains ownership of the GeoJSON file and all of the data contained within it, including the PDF reports and images. DeepWalk owns the raw data used to generate these deliverables and has the rights to generate new deliverables and use the raw data to improve internal systems.

Deliverables

Where does the data live?

With DeepWalk's web package subscription, all files are hosted on DeepWalk's web servers. GeoJSON mapping files and ArcGIS packages point to DeepWalk's cloud hosting solution, reducing file size to <1MB per mile of sidewalk inspected.

Without DeepWalk's web package subscription, files are migrated to the host's storage solution after data collection is completed. The storage requirements are 200MB per mile with PDFs or 50MB per mile without PDFs.

Does DeepWalk integrate with ArcGIS?

Yes, learn more about our Esri ArcGIS integration!

Can I add manual fields to collect other sidewalk related data points?

Up to 5 custom manual tags can be added to the data collection process. This allows the data collector to collect information on any sidewalk related feature, including but not limited to: utility boxes, pedestrian signals, transit shelters, signs, etc.

What if I have already collected the data?

Data can be merged in ArcGIS or any other GIS platform.
