Now the systems have been used in demonstration site in the Experiment Base of Shanghai Precision Agriculture. Based on the idea of spatial-oriented, object-oriented, user-oriented, the Farm Geographic Information System for precision farming of rice was developed, which is characterized by intelligence and visualized. The Decision-making Management System is integrated with rice growth model, expert model for rice cultivation. The DGPS, RS, GIS and intelligence sensors and computer technique were adopted in building the artificial intelligence system for measuring grain yield that is installed in combine harvester, so the combine harvester could provide the grain yield distribution map real-timely. The environmental and economic assessment shows that the precision rice farming applied in the demonstration site will benefit the society, economy and ecology greatly.展开更多

Climate change and climate variability have enormously affected the state of agricultural productivity and hence could result in food insecurity. As many ongoing projects use Boolean suitability analysis, land use planning, management recommendations sores, it still remains inadequate to support rural resource poor farmers. This then, is affecting livelihood and agricultural productivity. In this paper, a geostatistical quantitative method to support a geographic information system (GIS) based on multi-criteria decision support system (GMCDSS) for an enhanced land suitability assessment (LSA) and landuse planning (LP) was devised. Project findings indicated that, recommended farm inputs could be estimated and applied accordingly at farm plot levels Soil amendment indicators (e.g., 1.0 t/ha lime + 1.0 t/ha gypsum was estimated for liming) was quantified and currently, farmers can save money in soil fertility management. It has shown that, instead of applying 5.0 t/ha poultry manure (PM) or five bags of N-P-K fertilizer (rate of 15: 15: 15 N-P2O5-K2O/ha) + two bags of sulphate of ammonia (SA), a farmer may apply 2.0 t/ha PM + two bags 15:15:15 N-P2O5-K2O/ha + one bag of SA. GMCDSS assessment has proved to be fundamental in: (1) urban planning; (2) ensuring food security; (3) poverty reduction and interventions to the effects of climate change and climate variability.展开更多

The complexity of the different features of the city, the several scales of representation, the multi-dimensional objects and the historical, anthropic, formal relations have produced different kinds of information requiring a flexible instrument that is able to transcribe images, charts, texts and symbols in a single model of representation. In the perspective of creating a fundamental cognitive framework, the research team paid attention at drawing up a GIS (Geographic Information System) for documenting and managing historic urban heritage. The idea is to have a structure able to collect data like a logic archival system or an open database, which can immediately be consulted and constantly implemented. Indeed, the aim of this GIS is to organize, manage, query and visualise the peculiar aspects which characterize Catania's architectures. Thanks to multi-directional "access-windows" it is possible to navigate through its contents (texts, drawings, 3D rendering, pictures, historical documents). The system will also allow the integration of several documents in a common geo-database up to visualise the most meaningful details. Its use could assure suitable proposals of urban transformations and coherent plans in using and/or managing heritage goods for a sustainable city development.展开更多

IOCG ore deposits can have enormous geological resources with significant reserves of base, precious and strategic metals, are economically attractive targets for mineral exploration worldwide, but are still unknown in the northeast Russian. It was localized in Tarinskiy ore node (eastern Yakutia) field of brecciated altered rocks with sulfide and iron-oxide cement is a first in eastern Yakutia nature anomaly of IOCG-type with iron-oxide Cu-Au ± U specialization, that was formed close to the surface of Rep-Yuruinskiy pluton. It should be of interest as a new precious metals world class deposit type in northeast of Russia.展开更多
