Agriculture cropland soil moisture information plays a significant role in the management of agricultural policy, food security, and food prices. For better utilizing and reusing the agricultural information and knowledge, US Departments of Agriculture (USDA) National Agricultural Statistics Service (NASS) monitors US crop soil moisture condition using weekly field observations for counties in 45...
Geospatial web service of agricultural information has a wide variety of consumers. An operational agricultural service will receive considerable requests and process a huge amount of datasets each day. To ensure the service quality, many strategies have to be taken during developing and deploying agricultural information services. This paper presents a set of methods to build robust geospatial web...
The Remote Sensing Flood Crop Loss Assessment (RF-CLASS) is a system of geospatial Web services that provide comprehensive services to decision makers in assessing flood-induced crop loss. It serves a series of vector-based geospatial data. Traditionally, these data are visualized on the Web through a open Web Map Service (WMS) while the geospatial data are kept in either a geo-database or a vector-feature...
Agriculture is one of the most affected sectors by the flood. Spaceborn remote sensing is widely used for flood mapping and monitoring in recent decades. Some applications such as flood crop loss assessment require data with fine temporal resolution to monitor short-lived flood. MODIS is providing remote sensing data with 1–2 days temporal resolution which has frequently been used for flood mapping...
The Pub/Sub, short for Publish-Subscribe, is a flexible mechanism perferred by many users who'd like to passively know the changes of situation. Once a new message is published by a provider, all the subscribers to the specific kind of messages will receive the message and make corresponding responses. In agricultural crop monitoring, such mechanism is very helpful in enhancing the efficiency of message...
The timely retrieval of remote sensing imagery by farmers and decision makers is very important for current agricultural activities. Through the various kinds of imageries of agricultural fields, people can conclude the status of the fields and figure out what kind of crops are suitable and how to cultivate and irrigate the fields. This paper demonstrates how to take advantage of open web service...
GeoPackage, an open format for geospatial information, provides a gateway to bridge agricultural geographic information and mobile devices such as smartphones and tablets. In this paper, we present a Cordova framework based GeoPackage mobile application to support field operations in agriculture. By implementing GeoPackage SDK on mobile application, GeoPackage files can be easily accessed, managed,...
17 tomato cultivars inoculated with larva nematodes were used in this paper to investigate their resistance to root knot nenatodes. The results showed that gall index of LA1312, 3601, HA4402, LA1007 were higher than other tomato cultivars. Compared with control ‘Caihong101’, root activity of LA0655 was higher, and the lowest root activity was observed in 3601, whose gall index was the highest among...
Objectives To clarify the difference in health-promoting lifestyles between agricultural and non-agricultural workers in Japan, a cross-sectional study was conducted on 627 residents living in a town with a mixed rural–urban population. Methods The subjects were divided into 8 groups by job (agricultural and non-agricultural), age (young and old), and gender (male and female). To evaluate the subjects’...
