EO4Agri Analysis – Questionnaire

Blog by WirelessInfo and Club of Ossiach

The important input for future business orientation of EUXDAT can be analysis, which was provided by EO4Agri project. We will publish some parts from the report Mid-Term Workshop – User Requirements and Gap Analysis in Different Sectors Report https://www.eo4agri.eu/sites/eo4agri.eu/files/public/content-files/deliverables/EO4AGRI_D2.3-Mid-Term-Workshop—User-Requirements-and-Gap-Analysis-in-Different-Sectors-Report_v2.0.pdf

As part of the determination of the status of use and handling of EO (RS) data, was a questionnaire with 38 questions was prepared in consultation with members of the EO4AGRI team. The number of possible alternative responses ranged from binary (yes/no) to 29 alternative responses. Some questions were for information only. However, some of the issues are crucial for determining user requirements in the future.

The answers to the key questions for further research are as follows:

Forms response chart. Question title: 20 What spatial resolution (ground sample distance) of input data do you usually get?. Number of responses: 48 responses.

Forms response chart. Question title: 21 Is the spatial resolution (ground sample distance) you marked in the previous question sufficient for your work?. Number of responses: 49 responses.

Forms response chart. Question title: 22 If the spatial resolution (ground sample distance) is not sufficient, indicate which would be appropriate.. Number of responses: 38 responses.

Forms response chart. Question title: 23 Do you use free data, such as automated calculations of NDVI indexes published on the web?. Number of responses: 51 responses.

Forms response chart. Question title: 30 Are you interested to use remote sensing to educate the different stakeholders and user groups concerning benefits of cooperative and integrative use of information?. Number of responses: 50 responses.

Questionnaire – answers to the key questions

The questionnaire was answered by 60% of respondents from the private sector and 26% were from associations, the rest is the research sector, universities, etc.

75% of respondents state that they are well acquainted with EO issues, which corresponds to their answers to questions concerning their participation in broad cooperation across all platforms from government to research. 80% of respondents who grow cereals are mainly interested in the effect of using EO information in the form of increased yield and profit, but at the same time they are also interested in the ecological side of their business in the field of precision agriculture. 55% of respondents farm for less than 30 ha (of which 20% for less than 5 ha), but 35% farm for more than 250 ha. Respondents see difficulties in interpreting remote sensing data and real-time unavailability data as the main obstacles in the more significant use of EO for agriculture. 80% of respondents use data made available through public servers and the same number use multispectral data from Sentinel and LandSat satellites for their work at least once a week. RGB data is used by 40% of respondents. Respondents consider the ground sample distance to be insufficient, when 32% of respondents require data with a GSD of less than 1 m and another 42% of respondents require data with a GSD of less than 5 m! Only 10.5% of respondents are satisfied with the current GSD of Sentinel 2 satellites. Two thirds of respondents state that they buy data at a price of less than 5 Euro per hectare. The same number of respondents indicates that the yield from hectares will rise by up to 20 euros thanks to EO information.
