Historic Landscape

The article deals with a comprehensive information system of the historic Vltava River valley. This system contains a number of resources, which are described. For old maps, which are the basis of the whole system, their georeferencing and potential problems in creating seamless mosaics are described. Other sources of data include old photographs, which are localized and stored in the system, along with the definition point of the place from which they were probably taken. The vectorization of data is described, not only for area features used for the analysis of land-use changes, but also for the vectorization of contours. These were vectorized from old maps and are substantial for the creation of historic DEM. Vectorized footprints of buildings and vectors of other functional areas subsequently serve as a basis for the procedural modeling of the virtual 3D landscape. The creation of such a complex and broad information system cannot be described in one article. The aim of this text is to draw attention to a possible approach to the presentation and visualization of the historic landscape, along with links to important documents.

Tank Information System is a web application which provides comprehensive information about minor irrigation tanks of Telangana State. As part of the program, a web mapping application using Flex and ArcGIS server was developed to make the data available to the public. In course of time as Flex be-came outdated, a migration of the client interface to the latest JavaScript based technologies was carried out. Initially, the Flex based application was migrated to ArcGIS JavaScript API using Dojo Toolkit. Both the client applications used published services from ArcGIS server. To check the migration pattern from proprietary to open source, the JavaScript based ArcGIS application was later migrated to OpenLayers and Dojo Toolkit which used published service from GeoServer. The migration pattern noticed in the study especially emphasizes upon the use of Dojo Toolkit and PostgreSQL database for ArcGIS server so that migration to open source could be performed effortlessly. The current ap-plication provides a case in study which could assist organizations in migrating their proprietary based ArcGIS web applications to open source. Furthermore, the study reveals cost benefits of adopting open source against commercial software's.

Abstract The international scientific community has long recognized the need for coordinated drought monitoring and response, but many factors have prevented progress in the development of a Global Drought Early Warning System (GDEWS): some of which involve administrative issues (coordinated international action and policy) while others involve scientific, technological, and logistical issues. The creation of the National Integrated Drought Information System (NIDIS) Portal within the United States provided an opportunity to take the first steps toward building the informational foundation for a GDEWS: that is, a Global Drought Information System (GDIS). At a series of workshops sponsored by the World Meteorological Organization (WMO) and Group on Earth Observations (GEO) held in Asheville, North Carolina, in April 2010, it was recommended that a modular approach be taken in the creation of a GDIS and that the NIDIS Portal serve as the foundation for the GDIS structure. Once a NIDIS-based Global Drought Monitor (GDM) Portal (GDMP) established an international drought clearinghouse, the various components of a GDIS (drought monitoring, forecasting, impacts, history, research, and education) and later a GDEWS (drought relief, recovery, and planning) could be constructed atop it. The NIDIS Portal is a web-based information system created to address drought services and early warning in the United States, including drought monitoring, forecasting, impacts, mitigation, research, and education. This portal utilizes Open Geospatial Consortium (OGC) web mapping services (WMS) to incorporate continental drought monitors into the GDMP. As of early 2012, the GDM has incorporated continental drought information for North America (North American Drought Monitor), Europe (European Drought Observatory), and Africa (African Drought Monitor developed by Princeton University); interest has been expressed by groups representing Australia and South America; and coordination with appropriate parties in Asia is also expected. Because of the range of climates across the world and the diverse nature of drought and the sectors it impacts, the construction and functioning of each continental drought monitor needs to be appropriate for the continent in question. The GDMP includes a suite of global drought indicators identified by experts and adopted by the WMO as the necessary measures to examine drought from a meteorological standpoint; these global drought indicators provide a base to assist the global integration and interpretation of the continental drought monitors. The GDMP has been included in recent updates to the GEO Work Plan and has benefited from substantial coordination with WMO on both their Global Framework for Climate Services and the National Drought Policy efforts. The GDMP is recognized as having the potential to be a major contributor to both of these activities.

Abstract. The status quo of the land management and information system in Nepal is a far cry from where the developed world stands. Paper-based system is still the spine of this system which is tedious, less accurate and difficult to store and update. So, there is a need for a digitized system providing country’s land authorities with a powerful tool that creates a unified platform for the creation of an accurate spatial database, timely maintenance and updating of the database in a dynamic web platform. The database including spatial data of land features can be utilized to create a web-based thin-client mapping application which meets the needs of all the stakeholders (government authorities from Survey Offices, Land Revenue Offices, Land Reform Offices, etc.). This paper shows the use of open-source software for the creation of a web mapping system including QGIS, PostGIS extension of PostgreSQL for spatial database, HTML for markup, CSS for styling, JavaScript, Leaflet, Open-Layers for client-side scripting and Geo-Django for backend designing. The developed methodology can be utilised for the preparation of an interactive thin-client web mapping server that enables general users to dynamically view data, zoom, pan and search from the database and obtain land information. The login system enables administrators with various access to upload, verify and edit data along with performing various spatial operations while the super admin is entitled to access to the PostgreSQL database. The major finding is that the use of a thin client application for a land information system is beneficial for all stakeholders. It is also a measure of the performance of land authorities allowing better planning, preparedness, and allocation of resources.

The Creation

We reconstructed the 100 year history of the botanical composition of a small (19 km2) park (Bic National Park, Bic/St. Fabien, Quebec) located within an agricultural landscape. Using 64 historical sources and a botanical field survey, we documented changes in the native and exotic vascular flora that occurred before and after the creation of the park in 1984. We evaluated how many native species were lost from 1984 to 2005, and the number of exotic species that became established during the same period. A total of 585 plant taxa were found in Bic National Park before its creation, of which 488 (83%) were native. The park harbours more taxa today (710) than in the past, but the proportion of exotic taxa has increased significantly (from 16% to 25%) since 1984. Despite its small area, Bic National Park has very successfully preserved its flora during its 21 year history. Thirteen species have likely been extirpated from the area occupied by the park. However, 12 of these 13 species have not been seen since at least 1957, so they were probably extirpated before the creation of the park. On the other hand, the creation of the park did not stop the introduction of exotic species. Land-use changes, an increase in the number of visitors, and horticultural plantings are probably the main causes explaining the rise in the number of exotic taxa observed during the last 21 years. A small park located far from urban centres may preserve its flora, but is not necessarily a bastion against exotic species.

Abstract. In recent years the frequency of high-flow events on the Meuse (northwest Europe) has been relatively great, and flooding has become a major research theme. To date, research has focused on observed discharge records of the last century and simulations of the coming century. However, it is difficult to delineate changes caused by human activities (land use change and greenhouse gas emissions) and natural fluctuations on these timescales. To address this problem we coupled a climate model (ECBilt-CLIO-VECODE) and a hydrological model (STREAM) to simulate daily Meuse discharge in two time-slices: 4000–3000 BP (natural situation), and 1000–2000 AD (includes anthropogenic influence). For 4000–3000 BP the basin is assumed to be almost fully forested; for 1000–2000 AD we reconstructed land use based on historical sources. For 1000–2000 AD the simulated mean annual discharge (260.9 m3 s−1) is significantly higher than for 4000–3000 BP (244.8 m3 s−1), and the frequency of large high-flow events (discharge >3000 m3 s−1) is higher (recurrence time decreases from 77 to 65 years). On a millennial timescale almost all of this increase can be ascribed to land use changes (especially deforestation); the effects of climatic change are insignificant. For the 20th Century, the simulated mean discharge (270.0 m3 s−1) is higher than in any other century studied, and is ca. 2.5% higher than in the 19th Century (despite an increase in evapotranspiration). Furthermore, the recurrence time of large high-flow events is almost twice as short as under natural conditions (recurrence time decreases from 77 to 40 years). On this timescale climate change (strong increase in annual and winter precipitation) overwhelmed land use change as the dominant forcing mechanism.

With the partitioning in 1373 of the domain of Nikola Altomanovic, a Serbian feudal lord, the old political core of the Serbian heartland was shattered and the feudal Bosnian state considerably extended to the east. The region was crossed by the Tara river, mostly along the southeast-northwest "Dinaric course". Although the line along which Altomanovic?s domain was partitioned has been discussed on several occasions and over a comparatively long period, analyses show that the identification of its section south of the Tara is still burdened by a number of unanswered questions, which are the topic of this paper. An accurate identification of this historical boundary is of interest not only to historiography, but also to archaeology ethnology, philology (the history of language and dialectology in particular) and other related disciplines. The charters of Alphonse V and Friedrich III concerning the domain of herceg Stefan Vukcic Kosaca, and other historical sources relating to the estates of the Kosaca cannot reliably con?rm that the zupa of Moraca belonged to the Kosaca domain. The castrum Moratsky and the civitate Morachij from the two charters stand for the fortress near the village of Gornje Morakovo in the zupa of Niksic known as Mrakovac in the nineteenth century, and as Jerinin Grad/Jerina?s Castle in recent times. The zupa of Moraca, as well as the neighbouring Zupa of Brskovo in the Tara river valley, belonged to the domain of the Brankovic from the moment the territory of zupan Nikola Altomanovic was partitioned until 1455, when the Turks ?nally conquered the region thereby ending the 60-year period of dual, Serbian-Turkish, rule. Out of the domain of the Brankovic the Turks created two temporary territorial units: Krajiste of Issa-bey Ishakovic and the Vlk district (the latter subsequently became the san?ak of Vucitrn). The zupa of Moraca became part of Issa-bey Ishakovic?s domain, and was registered as such, although the fact is more di?cult to see from the surviving Turkish cadastral record. The zupa of Moraca did not belong to the vilayet of Hersek, originally established by the Turks within their temporary vilayet system after most of the Kosaca domain had been seized. It was only with the establishing of the San?ak of Herzegovina that three nahiyes which formerly constituted the Zupa of Moraca (Donja/Lower Moraca, Gornja/Upper Moraca and Rovci) were detached from Issa-bey?s territory and included into the San?ak of Hercegovina. It was then that they were registered as part of that San?ak and began to be regarded as being part of Herzegovina.
