Question 1

We use DJI drones for survey and inspection and want to overlay or embed kmz files, shapefiles, any line work into the video. Will LineVision support this?

Jeff · Accepted Answer

Yes - with some DJI models, and LineVision Desktop - Ultimate, you can use the data from the DJI Fight Record log TXT file to geotag the video so that an approximation of the "camera-target-footprint" shows on the map with this data. You can then enable the map overlay. But again remember this is really an approximation. Unlike the aircraft gimbal systems, the DJI's do not have a laser rangefinder to get LineVision all the ideal metadata parameters to get the 4-corner information really accurate. Also at this time you cannot export a video file with the video overlaid, the client will at least need the LineVision Desktop - Basic edition to view the data overlaid on the video.

Also, all versions of LineVision also allow you and clients to video player synced with a moving map flight route and data side by side.

Question 2

Does LineVision Desktop have the ability to also parse mission and security KLV metadata from MISB FMV extract into the .GPX file or just GPS-related data?

Jeff · Accepted Answer

There can be all kinds of keys in the MISB FMV so for the sake of making the software more usable for the vast majority of users, we currently only pull out GPS & related data.

However, we certainly can parse all or some specific mission/security metadata and get that into a GPX or other file type. We work with customers on a case by case basis for this type of customization and are happy to explore what would be involved if you are interested.

Question 3

I need to be able to show video and my flight route on a Google Map or Google Earth in real time as the video plays. Is this something your software can do?

Jeff · Accepted Answer

Yes - Our LineVision software allows you to view video files with continuous GPS coordinates a map for dynamic an interactive playback along a flight route. The LineVision Google Earth Extension lets you do this with Google Earth and our LineVision Desktop lets you do this with Esri ArcGIS Maps.

Question 4

How can I share the videos I will make with LineVision with my clients? Will they also have to buy the LineVision software to view my content?

Jeff · Accepted Answer

The geoProject format is the ideal way to deliver an interactive and immersive map-based deliverable to your client. (Click here for more on geoProjects.)

However, to offer that type of functionality, requires software that make that all work together.

If you are using the Remote GeoSystems geoProject format for your deliverable, then your client will need some sort of version of LineVision Basic edition or higher to view the saved geoProject.

This can be any of the following LineVision versions: LineVision Google Earth Extension, LineVision Desktop, LineVision Esri ArcMap Add-in or LineVision Online for Enterprise.

Since we do offer the monthly plans, so you could subscribe for your client and turn off their subscription for the months that its is not being used.

Alternatively you could create screen capture of the LineVision running if you just needed to send your client a movie. There are also the automated reports that can be exported in Microsoft Word and Excel, as well as mission plans that can be exported as KML files. But again, the map interactivity with video requires the LineVision software currently.

Question 5

Do you have a published standard CSV format so I can be sure my geospatial video GPS data companion files are compatible with LineVision?

Jeff · Accepted Answer

Yes. LineVision accepts many different GPS Data companion file types and to make it easy we have a published very simple CSV spec for LineVision.

The format is as follows:

Column 1: Latitude

Column 2: Longitude

Column 3: Altitude

Column 4: UTC Time

Column 5: Speed

Column 6: Course

The 1st row MUST be the following:

LATITUDE, LONGITUDE, ALTITUDE, UTCTIME, SPEED, COURSE

From there, each additional row just needs to be the corresponding values.

Question 6

How do I get my DJI drone to record and geotag video with SRT files for LineVision?

Jeff · Accepted Answer

In the DJI Go App, choose the MENU option on the right side of the screen for Images and Video. Choose the Video icon and change file type from .MOV the default to .MP4. Choose the Option tool icon and TURN ON Video Caption. That option needs to be ON for the .SRT files to be saved with the .MP4 on your SD Card when you record during a flight.

Please note: you must have a DJI model that properly logs the GPS as an SRT file.

Question 7

Is LineVision software compatible with video from DJI drones?

Jeff · Accepted Answer

Yes - All LineVision versions accept geotagged videos from certain DJI models that log the .SRT file with GPS data along with the video files.

Based on internal research and customer feedback the following DJI models should support recording video with the .SRT file:

Mavic Pro

Inspire 1 & 2

Phantom 3 Pro

Phantom 4 Standard (for some reason it seems DJI did not include .SRT file logging capability with the Phantom 4 Pro.)
