The Impact

The modern meaning of accurate crop cultivation is closely associated with the new information technologies - geographic information and global positioning systems. Latvia has not published the results of research on soil conditions and the impact of unregulated factors of production conditions on winter wheat growth and yield. Analysis of results of studies aimed to clarify the difference of soil treatment facilities, as the criteria for the treatment of soil using soil characterizing Non-plant growth and development factors. Investigations were carried out in 2005 – 2007 on the production plantations of the Kurpnieki field, the Vecauce Study and Research Farm of the Latvia University of Agriculture. The results, while on a previous year, research on soil management measures to optimize the opportunities associated with global positioning systems, precision field management implementation practice shows that in order to obtain objective indicators and to gain the desired results, it was not enough for one season observation, since a large role in shaping the harvest is the meteorological conditions during the growing period. Unregulated factors: organic matter content, Ap horizon thickness, as well as the relative height above sea-level properties of materials research is the prerequisite for geographic information system-based resource-saving cultivation technology field-crop cultivation.

Production Agriculture

This chapter introduces the use of geographic information systems (GIS) and global positioning systems (GPS) in agricultural production. Precision agriculture is a catch-all term that describes using GIS and GPS technologies to manage specific areas of fields. Precision agriculture technologies use information from multiple sources to assist farmers in making crop production and management decisions based on the variability of production potential within fields. In this chapter, we describe the technologies used in production agriculture and we review some of the research associated with the use and future trends of these technologies. The purpose of this chapter is to define and explain GIS and GPS technologies used in agriculture and some of the economic benefits, impacts, and challenges of using these technologies.

Systematic Framework

Tourism implies movement. This study tests the effect of past experience on tourists’ spatiotemporal behaviour in the context of urban multi-attraction visitation. Differences between first-time and repeat visitors are examined using global positioning systems technology and a post-visit survey of tourists staying at 10 different hotels in Lisbon. The impact of prior destination experience is assessed regarding intra-destination movements as well as multi-attraction visitation patterns, within a systematic framework in order to assess tourists’ intra-destination spatiotemporal behaviour. Hypothesis testing confirmed destination familiarity as an influential factor of urban tourists’ behaviour in space and time.

Northern Prawn Fishery

The impact of global positioning systems (GPS) and plotter systems on the relative fishing power of the northern prawn fishery fleet on tiger prawns (Penaeus esculentus Haswell, 1879, and P. semisulcatus de Haan, 1850) was investigated from commercial catch data. A generalized linear model was used to account for differences in fishing power between boats and changes in prawn abundance. It was found that boats that used a GPS alone had 4% greater fishing power than boats without a GPS. The addition of a plotter raised the power by 7% over boats without the equipment. For each year between the first to third that a fisher has been working with plotters, there is an additional 2 or 3% increase. It appears that when all boats have a GPS and plotter for at least 3 years, the fishing power of the fleet will increase by 12%. Management controls have reduced the efficiency of each boat and lowered the number of days available to fish, but this may not have been sufficient to counteract the increases. Further limits will be needed to maintain the desired levels of mortality.

Social Environmental

Geographic information is ubiquitous, from MapQuest in Google to the use of global positioning systems on PDAs and automobiles. More people use geographic information on a daily basis, from directions and a review of a local restaurant to building new infrastructures for communities. Therefore, libraries and librarians should be planning on how best to obtain, market, and provide this type of information for their users’ personal and professional needs. What are some of the emerging themes in geographic information systems, particularly for libraries? In the convergence of services and resources, emergent themes are cartography; platform/network development; “geoweb” services and resources; geodata management trends; and societal impacts. Sui (2004) postulates that GIScience research will be involved in “computational, spatial, social, environmental, and aesthetic dimensions” (p. 65), therefore “geocomputation, spatially integrated social sciences, social informatics, information ecology, and humanistic GIScience” are areas of research to watch (p. 65). This chapter will address these themes from both a GIS and libraries perspective.
