Distributed Processing of Large Satellite Images Using MapReduce

Advances in sensor technology and their ever increasing repositories of the collected data are revolutionizing the mechanisms remotely sensed data are collected, stored and processed.  This exponential growth of data archives and the increasing user’s demand for real-and near-real time remote sensing data products has pressurized remote sensing service providers to deliver the required services. The remote sensing community has recognized the challenge in processing large and...

Using GRASS GIS to Calculate Potential Global Solar Irradiation Using Canopy Heights as a Base Elevation Layer to Assist in the Landscape Scale Characterization of Aquatic Habitats

Water temperature variation  can have a significant impact on freshwater aquatic communities .  Elevated temperatures can lead to differences in predator/prey relationships and mortality in relatively non-mobile classes of aquatic species such as mussels.  Using native 64-bit GRASS 6.5 on 64-bit Centos Linux, a previously generated 18.2 m (60 foot) forest canopy height grid for the State of North Carolina ( 17237 Rows and 45102 columns )  was used as a base elevation...

FOSS4G CRUD Benchmark

Performance shoot-outs are being presented each year, at FOSS4G events1. The effort being made to prepare the benchmark, and the code changes returning back to the community resulting from this exercise are really helping to improve the software.

Currently, many web mapping applications are two way, in the sense that these applications are used to present and collect geospatial data from users. The examples ranges from sharing cycling tracks (with lots of points) to urban management...

Virtual Globes For Environmental Analysis

Virtual Globes were initially released as effective and intuitive tools to view satellite and aerial photos directly superimposed on the three-dimensional model of the globe. The constant update of increasingly accurate and detailed images and the ability to customize the content through the direct mapping on the globe of any geographically localized phenomenon (physical, environmental, social, etc.), has increased not only the common and popular use of virtual globes but has also offered...

An Open Source Mapping Application for Hatchery Release Data in the Columbia River Basin

The Fish Passage Center (FPC) maintains a hatchery database of anadromous salmonid species released from State, Federal, and Tribal hatcheries in the Columbia River Basin. This database is updated routinely throughout the fish passage season. Over the past year, the location of the hatcheries and the release sites were mapped and an online mapping application was developed to allow the users of this database a spatial view of where hatcheries have released anadromous salmonids throughout...

Exploratory visual pattern detection of mobile object data in attribute-time space

Recent years witnessed the emergence of massive individual-based movement data due to the location-aware devices such as global positioning system (GPS), mobile phones and radio-frequency identification (RFID). These data are overwhelming the techniques of traditional spatial analytic techniques. Researchers and practitioners are turning to spatio-temporal knowledge discovery and exploratory visualization techniques to find patterns, trends and relationships hidden in the large volume mobile...

Poster Dr Tetsuo Kobayashi, University of Utah

Numerical models, such as hydrodynamic and climate models, produce output with a large number of variables and a large number of grid cells and time steps. Further use of the resulting data products has been challenging, especially for further use outside the institute of origin. Due to the vastness of the data, simply downloading copies of data is impossible. Web services are therefore used to access subsets of the data. The most mature candidates for working with gridded data are OPeNDAP...

FOSS Tools for Geospatial and Agent Based Modelling to Evaluate Climate Change in an Agricultural Watershed

Land-use changes are typically modeled using geographic information systems because of the spatial nature of the data. But the complexity of coupled human and natural systems and the fourth dimension involved with change over time and time-series data expose some limitations of GIS tools when used on their own. In this paper we present the application of REPAST, a free and open source geospatial Multi-agent Model (a.k.a. Agent-based Model or ABM) to the dynamic simulation of greenhouse gas...

An innovative web services based GIS architecture for global biogeographic analyses of species distributions

Spatial patterns and properties of species richness in natural communities are of keen interest to biogeographers and conservation biologists as they describe key features of the location and distribution of the earth's biological diversity. Patterns of species richness are determined by constituent species range sizes, spatial locations of those ranges, species associations, co-occurrence and species interactions. Analysis of these phenomena at biogeographical scales, i.e. continental to...

Delineating Service Areas of Public Facilities

Defining the service areas of public facilities is an important task in urban planning. It is essential in assessing the quality, efficiency, and equity of all sorts of service provisions. In addition, delineating service areas is a prerequisite in many location analysis and spatial optimization applications.

Delineating the service areas of facilities can be a very complex process. Depending on the characteristics of the public facilities and the scale of spatial data, facilities can...

Integrating Social Attitudes and Spatial Data in Siting Power Lines

Siting of energy transmission power lines based on physical and regulatory constraints is a challenging and complicated multivariable spatial optimization problem for which GIS is well suited. Existing techniques typically include rasterization of constraint feature layers; application of a layer weighting and combination scheme using map algebra; and ultimately evaluation of optimal paths using least cost path analysis. Such an approach does not explicitly take into account social attitudes...

PRIO-GRID: A Unified Spatial Data Structure

Contributions to the quantitative civil war literature increasingly rely on geo-referenced data and disaggregated research designs. While this is a welcome trend, it necessitates geographic information systems (GIS) skills and imposes new challenges for data collection and analysis. So far, solutions to these challenges differ between studies, hampering replication and extension of earlier work. This article presents a standardized structure for storing, manipulating, and analyzing high-...

Integrating Open-Source GIS in a Computerized Blotter System

Public safety and security is an important issue especially to a growing metropolis such as Manila. With this, information about crimes and its analysis is of great importance not only to the police but as well as the general public. Studies show that there is a high correlation of crime and geography. Unfortunately, the current blotter system of most police precincts overlooks the accurate locations of crime. Integrating a Geographic Information System (GIS) to a blotter system will add a...

The Oklahoma/Kansas cyberCommons: An Ecological Informatics Research Laboratory

Integrative ecological research efforts often collapses under the weight of the massive amounts of data they hope to integrate. We share our approach to addressing this by building a loosely-coupled data and analysis toolkit. This toolkit draws heavily from from FOSS4G, OGC services and open standards to enhance scientific analysis capabilities. We share several examples where we organize, process, enhance and expose spatiotemporal datasets, such as: 1) weather radar reflectivity data before...

A Fast Search Mechanism for Multiple Raster Layers in MapWindow Open Source GIS

GIS raster data is a representation of cells or pixels arranged in rows and columns, where each cell signifies an attribute value representing different data types, such as slope, aspect, elevation, or temperature. Identifying and selecting the cells of a specific attribute value in the GIS programming world can be done fast in a single GIS raster layer. A problem might rise when the GIS programmer attempts to select a combination of multi values in exact cell locations in multi raster...

KMSTR, the transformation system of the Danish National Survey and Cadastre (KMS), has served as the official tool for transformation between Danish map projections and horizontal and vertical datums for half a century.

But it has evolved dramatically since then and survived through a range of three programming languages (Algol, Fortran, C), and a...
