This page intentionally blank Abstract Precision Agriculture (PA) is an approach to production in which an understanding of field and vineyard variability is used to enhance the certainty and efficiency of production. Thus, inputs are applied only where they are needed, and importantly for winegrowing, grapes may be selectively harvested and ‘streamed’ to particular target end uses (wines of different styles or price points). Key enabling technologies include geographical information systems (GIS) and methods of spatial analysis. Drawing on past (mainly viticultural) research, this project produced ‘PAT – Precision Agriculture Tools’ - a set of accessible ‘freeware’ tools that promote and facilitate low-cost adoption of PA. 3 This page intentionally blank 4 Table of Contents Abstract ...................................................................................................................................................................... 3 Table of Contents ....................................................................................................................................................... 5 Executive summary .................................................................................................................................................... 7 1 Project rationale and objectives .................................................................................................................. 8 2 Method ......................................................................................................................................................... 9 3 Project results and discussion .................................................................................................................... 11 3.1 Project level achievements ......................................................................................................................... 11 3.2 Contribution to programme objectives ...................................................................................................... 14 3.3 Productivity and profitability ...................................................................................................................... 14 4 Collaboration .............................................................................................................................................. 15 5 Extension and adoption activities .............................................................................................................. 15 6 Lessons learnt ............................................................................................................................................. 16 7 Recommendations ...................................................................................................................................... 16 7.1 Training in PAT for users ............................................................................................................................. 16 7.2 Software maintenance and ensuring legacy value of the PAT software .................................................... 16 8 Additional project information .................................................................................................................. 17 8.1 Project, media and communications material and intellectual property ................................................... 17 8.2 Equipment and assets ................................................................................................................................. 17 8.3 References ................................................................................................................................................... 17 8.4 Staff ............................................................................................................................................................. 19 8.5 Evaluation report......................................................................................................................................... 19 8.6 Financial report ........................................................................................................................................... 20 8.7 Acknowledgements ..................................................................................................................................... 20 Appendix 1: Free GIS for Precision Viticulture ....................................................................................................... 21 Appendix 2: Multivariate spatial prediction and comparison for on-farm experimentation ............................... 22 Appendix 3: PAT – Precision Agriculture Tools Plugin for QGIS, User Manual ...................................................... 23 5 This page intentionally blank 6 Executive summary Precision Agriculture (PA) is a management strategy that gathers, processes and analyses spatial, temporal and other data and combines it with other information to support management decisions according to estimated variability for improved resource use efficiency, productivity, quality, profitability and sustainability of agricultural production. Precision Viticulture (PV) is the application of PA in winegrowing. Over the last 20 years, vineyard variability and the development of PV has been a growing area of research worldwide, to the extent that, in Australia, winegrowing is arguably as much to the fore in the sophistication of its use of digital technologies as is the case in other cropping systems that have explored the use of PA. Thus, it has been demonstrated that vineyards are variable and that managing them as though they are homogenous through the use of uniform management is a sub-optimal strategy. Accordingly, PV approaches to grape and wine production, which employ high resolution spatial data to inform strategies such as selective harvesting, may be highly profitable. Whilst the sophistication and potential profitability of PV is suggestive of advanced application of digital technology, recently surveys in both the wine and grains sectors suggest that adoption of PV/PA, including new methods of on-farm experimentation which may support the targeting of management, will be greatly facilitated by factors which simplify the adoption process. Access to assistance, low cost and process simplification were identified as particularly critical. This project sought to address an opportunity in terms of both the cost and simplification of the spatial data analysis which is critical to PV/PA, by producing a suite of open source tools, accessible through a freeware platform, which may enable a non-expert to implement the core data analysis tasks which PV/PA require. This project was supported by Wine Australia, through funding from the Australian Government Department of Agriculture as part of its Rural R&D for Profit program, and CSIRO. Drawing on CSIRO-led research in PV/PA conducted over the last 20 years, the project produced a suite of tools for spatial analysis that are freely available and accessible. pyprecag is a Python library containing these tools which is accessed using ‘PAT’ (Precision Agriculture Tools), a Plugin for QGIS, a freeware geographical information system. This is supplemented by tools for the analysis of so-called ‘whole of block’ experiments, coded in R, a freeware statistical programming language, which is also accessible via PAT. Users do not need to have expertise in spatial analysis and geostatistics to make use of PAT and it is therefore hoped that the availability of these tools will greatly facilitate adoption of PV/PA.

    AGD Landscape & Environment 6 (2) 2012. 76-92. COMPARISON OF THE MOST POPULAR OPEN-SOURCE GIS SOFTWARE IN THE FIELD OF LANDSCAPE ECOLOGY SZEMÁN ISTVÁN1 1University of Debrecen, Department of Landscape Protection and Environmental Geography, Debrecen, 4032, Egyetem tér 1. E-mail: [email protected] Received 2 March 2012; accepted in revised form 21 December 2012 Abstract GIS (Geographic Information System) software is a very useful tool in modern landscape ecology research. With its help data can be obtained which can - after processing - help to understand and demonstrate the processes taking place in the landscape. Since direct environmental measurements and sampling from a large area are, in many cases, difficult or even impossible, modelling with GIS tools is very important in the workflow of landscape research and landscape analysis. In this article we review the best known open source GIS systems and geographic information tools with possibilities for landscape ecology application. Furthermore we will introduce all the basic concepts that are associated with these open source software programmes. We provide a comparative analysis of the most widely used open source GIS applications, where, through a specific example, we will examine how these tools are used to produce basic landscape metric indicators. We will examine those functions of the programmes that are necessary to produce a complete thematic map, and finally we will emphasize various other important functions of the software to give adequate information for those users who choose open source code GIS tools, for financial reasons or otherwise, to complete a landscape ecology analysis. Our opinion is that this type of comparison is much more informative than those done by proprietary software, because these latter are all based on a basic data library, and therefore yield similar results (proj4, gdal/ogr, jts/geos, etc.) to their ‘paid’ competitors.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Although open source softwares (OSS) for GIS and Remote Sensing are rapidly expanding and im- proving in the global context, there has been uncertainty at higher education institutions in de- veloping countries, such as the department of forestry (Dfo) at Unitech, Papua New Guinea (PNG), regarding appropriate GIS softwares and hardware to acquire and use for teaching and research purposes. The paper briefly describes the characteristics of some mature OSS and discusses their main capabilities, advantages and disadvantages. Their adoption in the Dfo curricula may be ad- vantageous in the long term, considering issues of learning curve steepness, versatibility, afforda- bility, effectiveness, and documentation available on them. Keywords Open Source Software; GIS Software; Forestry Education 1. Introduction GIS is a key technology for developing countries in domains such as environmental protection, urban manage- ment, agricultural production, deforestation mapping, public health assessment, and socioeconomic measure- ments. It is defined as a system of software components that maintain a spatially aware database, provides ana- lytical tools that enable spatial queries of the database, allows the association of locations with imported graphi- cal data, and provides graphical and tabular output.

  • A Selection of Software for Processing Geospatial Data Is Presented in Table 1.1 and Table 1.2. Note That You May Need Some Time
    A selection of software for processing geospatial data is presented in Table 1.1 and Table 1.2. Note that you may need some time to find the best software for a specific task or project. Terminology: Freeware: Freeware (a combination of the words "free" and "software") is software that is available for use at no cost or fee, but usually with one or more restricted usage rights. Compared the FOSS (see below) the source code is usually not published and hence the software can’t be modified and adjusted by 3rd parties. FOSS: Free and open-source software (F/OSS, FOSS) or free/libre/open-source software (FLOSS) is software that is both: 1) free software and 2) open source. It is licensed in the way that users are granted the right to use, copy, study, change, and improve its design through the availability of its source code. Free GIS software Description Terra MA2 (old SISM DEN) is a software product, a computational system, based on a Service Oriented Architecture (SOA), which provides the technological infrastructure required to develop operational systems for environmental risks monitoring and alert. TerraMA2 provides services to gather updated data through internet and to add it to the alert system database; services to manipulate/analyze new data in real time and check Terra MA2 if a risk situation exists by comparing with risk maps or a defined model; Monitoring, Analysis and Alert services to execute/edit/create new risk and alert models; services to create www.dpi.inpe.br/terrama2/ and notify alerts to system users; and other basic and advanced services.
