Over several years of research, numerous geo-analysis models have been developed. However, a collaborative barrier between model providers and model users still exists. The development of cloud computing has provided a new and promising approach for sharing and integrating geo-analysis models across an open web environment. To share and integrate these heterogeneous models, encapsulation studies should be conducted that are aimed at shielding original execution differences to create services which can be reused in the web environment. Although some model service standards (such as Web Processing Service (WPS) and Geo Processing Workflow (GPW)) have been designed and developed to help researchers construct model services, various problems regarding model encapsulation remain. (1) The descriptions of geo-analysis models are complicated and typically require rich-text descriptions and case-study illustrations, which are difficult to fully represent within a single web request (such as the GetCapabilities and DescribeProcess operations in the WPS standard). (2) Although Web Service technologies can be used to publish model services, model users who want to use a geo-analysis model and copy the model service into another computer still encounter problems (e.g., they cannot access the model deployment dependencies information). This study presents a strategy for encapsulating geo-analysis models to reduce problems encountered when sharing models between model providers and model users and supports the tasks with different web service standards (e.g., the WPS standard). A description method for heterogeneous geo-analysis models is studied. Based on the model description information, the methods for encapsulating the model-execution program to model services and for describing model-service deployment information are also included in the proposed strategy. Hence, the model-description interface, model-execution interface and model-deployment interface are studied to help model providers and model users more easily share, reuse and integrate geo-analysis models in an open web environment. Finally, a prototype system is established, and the WPS standard is employed as an example to verify the capability and practicability of the model-encapsulation strategy. The results show that it is more convenient for modellers to share and integrate heterogeneous geo-analysis models in cloud computing platforms.

An approach to transform Chinese historical books into scenario-based historical maps / Li He in Cartographic journal (the), vol 50 n° 1 (February 2013)  

Public [article]  inCartographic journal (the) > vol 50 n° 1 (February 2013) . - pp 49 - 65 Titre : An approach to transform Chinese historical books into scenario-based historical maps Type de document : Article/Communication Auteurs : Li He, Auteur ; Min Chen, Auteur ; Guonian Lu, Auteur Année de publication : 2013 Article en page(s) : pp 49 - 65 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie étrangère [Termes IGN] carte interactive [Termes IGN] cartographie historique [Termes IGN] Chine [Termes IGN] conception cartographique [Termes IGN] données spatiotemporelles [Termes IGN] histoire [Termes IGN] littérature [Termes IGN] monographie Résumé : (Auteur) Spatio-temporal information (e.g. time, location, person and event) recorded in detail in vast Chinese historical books can provide evidence about the movement of entities (e.g. people, family, army and weapons) and their underlying spatial behaviours. Furthermore, this information largely reflects the process of social development, which makes it valuable to both professional research and public awareness. However, this information cannot be easily expressed and visually utilized because it is often hidden in the text of historical books. Aiming to better realize the potential value of such abundant information derived from historical books and bridging the gap between historical research and geographic space, a feasible and appropriate approach is explored in this article, to guide the transforming process from historical books to historical maps. The hope is that providing the scenarios of historical events will benefit related historical and social research. First, the integral framework of the approach was introduced, and the detail of building the specific spatio-temporal framework for information matching was discussed. Based on the spatio-temporal framework, the specification for the representation of historical books was designed. By extracting the spatio-temporal data from historical books, organizing them according to the specification and matching them with the spatio-temporal framework, the scenarios of historical events in the book (e.g. wars, migration, diseases, natural disasters, mass movement, etc.) can be visually transformed into historical maps. As the most critical writing of the Chinese Twenty-Four Histories, the Records of the Grand Historian (also known as Shiji) was employed as an example to test the proposed approach.
