SURVEYING

Whether you are a surveyor or you need a mapping service to help out a surveyor, a photogrammetric flight is perfect to support and complete field measurements. Some of our local drone pilots have RTK and PPK drones to get quickly high precision. Otherwise, using ground control marks, you can get up to 3 centimeter absolute precision!


ORTHOMOSAIC

ORTHOMOSAIC

This basic product is always included in any job we deliver. This is a maps in true colors, georeferenced using ground control points or directly corrected using RTK. However, resolution and precision depend on the flight altitude and the type of camera used, in general the ground resolution is less than 5 centimeters in XY, while for Z we consider a value that doubles the one in XY, depending on how rough the terrain is. An orthomosaic is used to make a planimetry, locate infrastructure or measure surfaces of certain elements. Aurea Imaging offers to carry out this job. Example.

TERRAIN MODEL AND CONTOUR LINES

TERRAIN MODEL AND CONTOUR LINES

The same way orthomosaics are made, also a digital elevation models comes out as a result. Each point is observed from different angles and that is how a very precise point cloud is build. This point cloud is used to correct the orthomosaic, and also works for contour lines. Keep in mind that the generated model includes vegetation and structures, so in order to obtain a good output it is recommended to plan your flight when there´s minimum vegetation to improve the model accuracy.

PLANIMETRY

PLANIMETRY

Planimetry is the final output of a photogrammetric flight. On the orthomosaic, objects as fences, paths, streets, buildings or any other type of structures of interest are digitized. A planimetry is basically a base map in which precise area and location of structures can be calculated. On this base map it is establish a start point for a subsequent change detection. Due to all this, the planimetry is often printed as it is a detailed and precise representation of the property. Example

CALCULATION OF VOLUMES

CALCULATION OF VOLUMES

After ortomosaics and digital terrain model are processed, we can calculate volumes. The 3D point’s cloud that we get allow us to obtain millions of points with XYZ information. Currently it is difficult to make this type of calculations without drones due to the complexity of the irregular shapes presents in real life (stacks of logs, sand, vegetation or any material). Not only the volume of any stack can be calculated with a drone flight, but with several flights, how volume changes in time can be determined for soil movements or ground excavations.

NEW STRUCTURES DETECTION

NEW STRUCTURES DETECTION

New structures as pools, houses or terrain expansions can be detected comparing images from different dates. The base map would be an orthomosaic with the cadaster on it to delimit lots, and this is compared with a more recent flights in order to determinate the differences between the images. Cadaster actualization and audition in urban areas are recurrent topics, where a reliable and standardized change detection is needed.


AGRICULTURE

Since each crop has its particular applications, we classify them in 4 groups: forest, extensive crops, fruits and vegetables. Each group has a particular logo and applications which are described below.


NATURAL COLOR IMAGE

NATURAL COLOR IMAGE

An image in natural colors may not always be what show us in the clearer way what is happening with the crop (agronomically speaking), but it sure represent a good approximation of what we see during field trips. A visual inspection of the lot, where we can identify certain type of weed or a patch where there is no crop, is sometimes more useful than a vegetation index. Example.

RELATIVE BIOMASS

RELATIVE BIOMASS

The vegetation index mostly represents the biomass of a crop in a particular moment in time. The main components are the size and the internal structure of the plant; in a lesser extent it shows differences in water content or chlorophyll. Biomass analysis is mainly used to estimate the crop performance in early stages. It is really important to take into account the moment of the flight for the validity of the results. Tracking biomass through successive images of the crop allow us to detect early variations in the growth and identify areas with problems. Example.

Clorofila

RELATIVE CHLOROPHYLL CONTENT

Chlorophyll index indicate growth potential of the crop, because of nitrogen content it is the catalyzer for crop growth, this index is a great way to predict it. In crops like corn or wheat, the index can be used to generate prescription maps in order to apply additional fertilization. In fruit crops is widely used to detect plants with chlorosis. Moreover, in some cases this index also shows the biomass variations, especially when the relative biomass index becomes saturated as a result of flowering. Example.

ALTIMETRY

ALTIMETRY

The same way orthomosaics are made, also a digital elevation models comes out as a result. Each point is observed from different angles and that is how a very precise point cloud is build. This point cloud is used to correct the orthomosaic, and it also works for contour lines. Keep in mind that the generated model includes vegetation and structures, so in order to obtain a good output it is recommended to plan your flight when there´s minimum vegetation to improve the model accuracy. This application is widely used to plan sewer systems or analyze erosion problems. Example.

THERMAL MAP

THERMAL MAP

A thermal map is a great way to supervise crops under irrigation as in rice, vineyards, grains or potatoes. Map to program the workflow of irrigation pivots or evaluate the water advance in lots under irrigation or by inundation are just a few examples of the utility of this service. Crop temperature not only depends on water content in leaves, but biomass. Currently, models are being used to monitor growth beyond flowering by measuring evapotranspiration with thermography.

PLANTS COUNT

PLANTS COUNT

In Aurea we have developed algorithms to make automatic counts with accuracy up to 95%. This option is widely used by forestry companies to audit the survival of new plantations, or to evaluate land with fruit trees such as olives or citrus. At the moment it is not available for grains, except for certain cases at trial level.

FLOODED AREA

FLOODED AREA

Increasingly we are faced with the effects of climate change, and by its natural physiognomy the western European area suffers periodic flooding. At the time of preparing the sowing campaign, harvesting campaign or making an insurance report, a precise datum of the flooded area is required. By means of aerial photography, puddles and humid soil can be delimited, with the rest of the lot contrasted. The result is a map with the flooded percentage of the lot, and its absolute surface.

PLANTED AREA

PLANTED AREA

The planted area is the most requested product by owners of fields to negotiate rents and predict yield. With an aerial mapping, the client obtains a map with three classes: percentage and absolute area of planted area, unseeded area and area where it was planted but where the crop was not born. A simple way to converse with objective data at hand!



AUTOMATED CROP MANAGEMENT

The biggest challenge of today's agriculture is to provide producers with access to advanced technologies to optimize crop control and management. For this reason, Aurea signed an alliance with ClimaVista Agro, the collaborative web platform to follow, analyze and manage in an automated way up to 1000 hectares at no cost.

ClimaVista

CLIMAVISTA AGRO

ClimaVista Agro is a collaborative web platform that provides the producer with online access to personalized weather forecasts, vegetation index of the lots, phenological cycle of wheat (shortly also for corn and soybean) and task control panel. To follow the state of crops from sowing to harvesting, you only need to georeference lots and start navigating. Free up to 1000 hectares, ClimaVista Agro offers its community of users a space of consultations to experts of the sector and an exclusive service of drone images by order, supported by Aurea.

Join our network of service providers

Drones are found in more and more places and large organizations are determined to insert them into their workflows. Insurance companies, banks, government entities and agro-industries, they all require high precision air data in a standardized way. Aurea leads the next step: The Aurea Network, a community of pilots capable of responding nationally in a flexible and professional manner.
