Case Study: GEODIS uses “Vexcel Ultracam XP” to create orthophotomaps in Poland

20. 09. 2012 — The LPIS is homogenous geographical database covering the agricultural land. It’s a basic component of the IACS system which is primarily used as a tool for the administration and control of the European subsidies in agriculture. The LPIS system is based on the digital OPTHOPHOTOMAPS.  


The Agency for Restructuring and Modernisation of Agriculture (ARMA) was established in 1994 with the aim of supporting agriculture and rural development. ARMA has been designated by the Government of the Republic of Poland as an accredited paying agency. It deals with the implementation of instruments co-financed from the European Union budget and provides aid from national funds. The Agency is responsible for the implementation of the agricultural policy, cooperates with the Ministry of Agriculture and Rural Development. At the same time, ARMA is under the supervision of the Ministry of Finance within the scope of managing public funds.

The Polish accession to the European Union required the introduction of mechanisms which would allow for the implementation of the provisions of the Common Agricultural Policy (CAP). It was therefore necessary to establish administrative and technical structures for the administration of subsidies in agriculture.


The Land Parcel Identification System – LPIS is the only official geographic system on the basis of which the European Union, or the individual administration in member states, allocate subsidies to specific farmers. Establishment of the LPIS, building of the IACS system and accreditation of the paying agency were the basic conditions of the European Union to successfully close the agricultural chapter, before the accession of new candidate countries to the EU. GIS techniques are compulsory to be used for the maintenance of the LPIS database. Reference area and declared land use are the basic information which LPIS provides during the annual campaign of the aid application submission.

The LPIS system in Poland is developed with the use of digital cadastral data, photo interpreted boundaries of agricultural land and vector layer of so called fields of management, where the digital terrain characteristic are used for the classification.

The creation of the LPIS database requires acquisition of digital aerial images and production of digital orthophotomaps covering whole territory of Poland. High quality of the data is the basic condition for correct photo-interpretation of the agricultural areas and classification of the land use type.

In 2011 ARMA announced a tender for the supply of aerial images in RGB and IR and the creation of orthophotomaps covering territory of the Poland for the purposes of modernising and updating the LPIS system.

GEODIS, together with OPGK Rzeszów S.A. and ZAKŁAD USŁUG GEODEZYJNYCH I KARTOGRAFICZNYCH PRYZMAT SP, won the tender and acquired an order for area OB1, covering approximately 161,600km2, which is more than half of the total area of Poland.

The project extends from 2012 to 2014 and the area in question is divided up into GSD ≤0.25m and GSD ≤0.50m.




GEODIS has many years of experience in creating of data for LPIS. Besides the Czech Republic and Slovakia, we have also taken photographs in Romania, Macedonia and Slovenia for the purpose of LPIS establishment. In several countries we have used orthophotomaps to digitise the boundaries of agricultural reference parcel and have carried out various types of on the spot checks and inspections using aerial photography and GPS measurements. GEODIS is also the distributor of the leading SW package for LPIS – GISELLE, allowing it to supply comprehensive LPIS solutions for maintenance of LPIS including data and SW, with spatial attention to LPIS quality assurance.

In 2012 GEODIS took aerial photographs of Poland in the OB1 zone, which covers a total area of 67,000 km2, of which 62,600 km2 was with a GSD of ≤ 0.25m and 4,900 km2 was with a GSD of ≤ 0.50m.

The photographs were taken using a VEXCEL ULTRACAM XP large-format digital aerial camera with an image format of 17.310 x 11.310 pixels and pixel size of 6µm. This is currently the camera with the largest PAN format footprint of all large-format cameras on the market.

The flights were made with the support of a GNSS/INS apparatus on board the GEODIS aircraft.

The aerial photographs were taken from March to July 2012. The deadline for the last orthophotomaps for this year is the end of September 2012.

In 2012 GEODIS and its subsidiary company ARGUS GEO SYSTEM managed to take aerial photographs of an area covering 67,476 km 2 (25cm/pixel=62,601km 2, 50cm/pixel=4,875km2). This year Geodis will process orthophotomaps for an area of 21,400km2. For these shots GEODIS primarily uses a VEXCEL UltraCam XP digital aerial camera with a resolution of 196 Mpx, which was installed on the firm’s own aircraft, a CESSNA 402 and PIPER PA 31-350 Chieftain. A CESSNA 206 was also fitted out with a VEXCEL UltraCam X aerial camera as a backup. The firm used its own GEODIS MASON 2.1 navigation system and the APPLANIX inertial unit. The flight height when taking shots at a resolution of 25cm/pixel was approx. 4,000m; in areas with a resolution of 50cm/pixel it was approx. 5,700m.


The results of this project are orthophotomaps in RGB and NIR placed on the “1992” and “2000” map sheets of the Polish national coordinate system. Over three years a total of 4,722 map sheets will be processed at a scale of 1:10,000 with a GSD of ≤0.25m and 3,418 map sheets at a scale of 1:10,000 with a GSD of ≤ 0.50m.

Supplied together with the orthophotomap is an updated or new DTM. The main advantages of using the new VEXCEL UltraCam XP digital aerial cameras are as follows:

  • High-quality images

  • Fewer rows are shot

  • Saves time and money

  • Compatible with all standard photogrammetric applications
