Before you record your Streetviews, plan your recording day in advance. Here are some useful tips & tricks to ensure you are all set for a successful recording day!
Estimating the time needed for recordings
Estimate the time it will take you for you to record your Streetviews and organize your schedule accordingly.
Start by determining the road classes in the recording area and the number of kilometers per road class. By multiplying by your average real-world speed, the recording hours per day, and the percentage of duplicate recordings, you can calculate the total time needed to record a project.
Next, do a test run using just a mobile phone and an app to record a GPS track. Base the calculations on this data, specific to the real location. Once the recording has started, you can refine the calculations based on the new data.
- Reserve extra time for returning to blocked roads and to cover rainy days
- If you are recording with tourism in mind, no recording should be done on the days the dustbins are out for collection
- Add an 5 extra minutes to rig the car in the morning, and 5 more to store the equipment in the evening
Processing and setting up the Streetview Player
Processing usually requires the same amount of time as the recording. The two should be done in parallel.
Setting up and customizing the player should also be done in parallel to the recording, or even before using test data. You can then just add real data when it becomes available.
Preparing the camera equipment
A day before the recording:
- Charge the camera batteries
- Pack accessories (a set of clean lens protectors and empty SSDs)
- Pack adapters for wall sockets when traveling abroad
Bonus tip: An adapter for the car’s cigarette lighter can extend the operating time of the tablet. Alternatively, a USB power bank can be used. A suction cup holder for the windscreen helps to reduce unnecessary distractions.
Preparing the recording vehicle
- The recording vehicle should have automatic transmission and air conditioning
- Check the vehicle’s manual to find the OBD2 socket, and for how to access it
- Check whether the vehicle has a cigarette lighter to power the tablet for a long time. Otherwise a USB power bank might be needed
- A USB power bank also helps to extend the tablet operating time when hiking or cycling. 20,000mAh is the minimum capacity recommended.
Using the Remote Control
Remote Control – Map
To guide the driver, a background map for the Remote Control can really help. This can be done with map tiles from OpenStreetMap, map tiles made from aerial images or a specialized custom map.
Bonus tip: All map tiles that adhere to the common “slippy map tiles” standard will work with the Remote Control, and can be reused with the Creator processing program, the web player and the Android offline player.
The recording area can be defined by creating a kml/kmz overlay for the Remote Control map.
Roads to record can be shown by creating MBTiles as a transparent overlay for the Remote Control map.
Remote Control – Recording Area Overlay
Set up a set or optional recording areas to be shown as overlays on the map. These can be used to guide the driver.
Remote Control – Roads Overlay
Generate an optional set of semi-transparent map tiles to show as overlays to guide the driver to roads that need to be recorded.
