Aerial Mapping and Imaging

Kraken Media

An Orthomosaic is an ultra high definition image map created from the overlaying of an unlimited amount of smaller high definition images. Kraken uses the most modern technology to generate a Georeferenced Image that is true to scale and can be used to measure distance.

Find problems, quantify damage and estimate yields.  View NDVI and other indices to detect crop stress and variability. The normalized difference vegetation index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements, typically but not necessarily from a space platform, and assess whether the target being observed contains live green vegetation or not.

What is NDVI to you?

NDVI is not a new formula by any means. It’s been available to farmers from satellites as an entry-level aerial perspective for a while. It has been very easy to get into and produce. I think that’s why it’s been so widely used.

What is the value of NDVI?

Where we see value is variability. There is always variability in all fields. NDVI highlights this variability and makes it easier for your eyes to see. When you can easily see variability, you can make quicker decisions.

What are some of the challenges with using NDVI?

One of the challenges with using NDVI is that you’re not always dealing with absolute values. When lighting conditions and cloud cover change, the camera lens gives you a value of what it sees but doesn’t account for the atmospheric change. If we fly over the same fields on different days with the same camera, you should get the same values… but you don’t. You’ll get the same variability but you won’t get the same numbers on the NDVI scale.

Because of this, it is extremely important to put your boots on the ground — every NDVI map should still be ground-truthed.

What are some misconceptions about NDVI?

No NDVI camera takes account for the soil, the fertility, or other problems in the field.  NDVI bases it’s decision off of the vegetation algorithm and imagery from that day.   NDVI maps do not replace an agronomist in the field.

Are yield estimations valuable to a grower?

Not as much as you’d think. Guessing yield is not a critical or unknown component to a farmer. Growers have known how to do that their whole lives. They can take a small section of field, make a quick count, and extrapolate that across the entirety for an accurate estimation.

So what do growers want to know?

They want to know if they have problems on this 200 acre field today or can they move on to the next field and continue their daily routine. The immediacy of the data is what can make a big difference. False NDVI imagery from RGB cameras can even be valuable if they highlight inconsistency — it can be a huge time saver to quickly detect variance and then go to the spot and make a decision.

Why is NDVI so popular and what does it mean to you?

NDVI itself has been around a lot longer than other vegetation indices. It’s the most prevalent so that’s why it’s talked about more than others. NDVI shows you the amount of photosynthesis in plants. But unless you’ve controlled for all possibilities, you can’t know if what it’s telling you is good or bad. NDVI is one piece of the puzzle — you’ve still got to get boots on the ground. It takes knowledge.

In order to effectively use a NDVI image for management decisions, or to diagnose what the issue is (as opposed to just where it is), one needs to understand the crop varietal, the history of the field, growth stage, fertilization, pesticides, and the plant growth environment (primarily moisture and temperature).

So what do the colors on NDVI maps mean?

NDVI is based on a false color scale that often uses green for high NDVI values and red for low values. Generally, green can mean a plant is healthy and red can mean a plant is unhealthy but you have to be very careful here. Green is not always good and red is not always bad. There are many factors at play.

For example, a very high NDVI value (green) could mean high weed pressure, as actively growing weeds have similar reflectance to actively growing crops.

Kraken provides accurate topographic modeling, with DSM and DTM

A DTM (Digital Terrain Model) is a topographic model of the bare earth – terrain relief – that can be manipulated by computer programs. The data files contain the spatial elevation data of the terrain in a digital format. Vegetation, buildings, and other man-made artificial features are removed digitally, leaving just the underlying terrain.

Alternately, DSM (Digital Surface Model) is usually the main product produced from photogrammetry, where it does contain all the features mentioned above, while a filtered DSM results in a DTM.

Kraken creates detailed and highly accurate 3D models and point clouds

Three-dimensional integration is an excellent tool for architectural firms, developers, and real estate agencies who want to show clients and prospective buyers how buildings or properties will look when completed. With skillful editing, we can integrate or composite 3D architectural renderings supplied by our clients into live aerial shots. This technique enables our clients to see the finished building on the site and in relation to other physical features.

Kraken's drones offer higher quality images and more usable data. We have the ability to arrive at a farmer's crop minutes after a weather event or track a construction companies progress on a building project over a years time.


Growers Need Same-Day Data.

Time is your most valuable resource. During the growing season, you need to be able to detect and solve problems. Kraken captures the imagery and makes it possible for our clients to view, annotate, and share maps that will allow collaboration with others to help you take action.


Better data, in dramatically less time.

Whether you’re inspecting a new building or investigating an insurance claim, it’s important to capture accurate data quickly. Drone mapping is a powerful new tool for inspection — allowing you to safely and easily capture a high-resolution aerial view of a site in minutes.

Back in the office, or out in the field, it’s easy to analyze high-fidelity reconstructions of sites, make measurements and share comments to help you make better and faster decisions.


Easily monitor progress on your construction site.

There’s a lot to keep track of on your job site — project progress, the location of equipment, the volume of materials left — and an aerial view makes it all a lot easier.  The latest generation of drones and cloud-based image processing put professional-quality aerial imagery into the hands of builders and project managers in a way that is faster, and more cost-effective than ever before.


Powerful aerial data for your mine.

Drones and the powerful aerial data they provide are bringing cost and time-saving innovations to a variety of mining processes. Professional-quality maps and 3D models empower you to instantly calculate aggregate volumes, keep track of equipment locations and monitor safety environmental compliance.

Web-based, button-click map sharing means you can collaborate with team mates both onsite and back at the office, making sure that everyone has access to the data they need.
