An Open Architecture for RESTful Geospatial Web Services
FDO Toolbox is a multi purpose geospatial tool I developed to utilise the powerful capabilities offered by the FDO (Feature Data Objects) API This presentation will introduce some of the major features of FDO Toolbox and how this tool can better help you work with geospatial data.

An example for such sensor systems are amateur weather stations which already monitor the local weather at many homes. Since these stations are often equipped with PC interfaces it is just an obvious step to distribute the measured data via the WWW. This presentation demonstrates a Web portal based upon Open Source components, which enables users to register their weather station and to publish the gathered data. The portal is realized as a Facebook application. It consists of a map and a time series view enabling users to display uploaded weather data as well as metadata about the weather stations. Once a user uploads data it is provided to the public via OGC's Sensor Observation Service (SOS) So, not only the developed application but also other SOS compliant clients can access the data in a standardized way.

Analysis of radiometric images of K, Th, U as well as their composite themes, correlate well with the MMGB geology and enabled a clear classification of the granitoids. The radioactive K content as well as U/K ratio played a great role in successful discriminating the granitoids from other rock types. A combination of K, U and Th in the R: G: B ternary diagram, classified the granitoids into two groups: a high K, U and Th group and a high K relative to U and Th group. Comparison of the radiometric results and the local geology showed that the syn orogenic intrusives (porphyroblastic granites, granodiorites, migmatitic granites and gneissic granodiorites) have high K content relative to U and Th, and on the other hand post orogenic intrusives (biotite granites, leucocratic granites and microgranites) are characterized by high abundances of all the three radiometric elements K, U and Th.

Author: Brent Wood Abstract: In order to complete a contract for a fisheries stock assessment and oceanographic survey undertaken on a commercial trawler,a robust, spatially enabled, standalone data capture/database system was designed and implemented. Data captured included near real time meteorological and oceanographic data, as well as automatically uploaded fisheries acousic, CTD and dissolved oxygen data. In addition, trawl survey data, icluding station, catch and individual fish length/sex/weight/gonad stage data from bottom and midwater trawls were also captured and uploaded. GIS capabilities for checking mapping the data as desired during the survey were also provided. Computers running mostly Open Source free applications were used to implement the system.

Author: Brent Wood Abstract: Environmental assessments are increasingly being undertaken using photographic transects as a nondamaging, non invasive method of sampling/recording biota, habitat and biodiversity related data. A critical aspect of working with such data is capturing the information recorded in teh photographs to support further analyses. NIWA is currently developing NICAMS (NIWA Image Capture, Analysis and Management System) an application based on ImageJ and PostGIS, to record image metadata, including time, location, depth and scale of each image, as well as ony observations pertaining to the images The ability to record these data directly into a spatially enabled database faciliates data validation, data management and further analysis of the captured observations using GIS and other statistical and modelling applications.

Author: Brent Wood Abstract: New Zealand has an extensive dataset of commercial fishing activities. Many of these include start and finish positions for each fishing activity undertaken.This presenations describes the process undertaken to model these data by converting start/finish points to area swept polygons which are overlaid on an equal area grid encompassing teh New Zealand EEZ. This generates a gidded spatio temporal model of benthic fishing activity which can be flexibly queried and further analysed or plotted using GIS and other statistical modelling tools. Rate the workshop I have *no *slight *huge interest in attending the workshop Styling with SLD, or How I Learned To Stop Worrying and Love XML Author: Mike Pumphrey Abstract: Geospatial data has no intrinsic visualization. This may seem counterintuitive to some, as we often convolve the content of the map with the look of the map. But while the content provides the backdrop, it is the visualization of the map that determines the storyline. Some web mapping software use Styled Layer Descriptors (SLD) to style maps. SLD is an open standard that encodes map styles using XML. Often times, it is necessary/worthwhile to create SLDs from scratch using only a text editor. This talk will showcase some best practices for making beautiful maps, while bravely dipping a toe into the verbose markup ocean that is XML. Brief mention will also be given to different ways of generating SLDs automatically. This talk is from the perspective of a map lover, not a programmer or web designer. Rate the workshop I have *no *slight *huge interest in attending the workshop PostGIS and Oracle Spatial Author: Simon Greener Abstract: Oracle Spatial and PostGIS are two of the most mature implementations of a spatial type system for their relevant host databases. With Postgres increasing in strength, and offshoot EnterpriseDB aiming to convert businesses running Oracle to EnterpriseDB/Postgres, the question of the relative merits of each of the spatial implementations arises. This talk will attempt to provide the audience with an understanding of the relative strengths and weaknesses of the two implementations so that they can feel they have some useful information which might aid decision making for new installations or conversions. Rate the workshop I have *no *slight *huge interest in attending the workshop Validation of Satellite Image with Ground Sensor Network based on OGC Web Services Framework Author: Sarawut Ninsawat Abstract: The utilization of satellite remote sensing image has been widely applied and been recognized as a powerful and effective tool in monitoring state of the natural environments. However, it does not provide enough reliable data due to various physical constraints especially by the absorption and scattering of atmospheric molecules and aerosols. The MODerate resolution Imaging Spectrometer (MODIS) are designed with the ability to characterize the spatial and temporal characteristics of the global aerosol filed which are used for atmospheric correction algorithm at calibration process. However, the validation process is still necessary to improve uncertainly estimates for satellite image products. This study focus on the implementation of standard OGC Web services (OWS) framework such as WCS, WFS, WPS and SOS to develop satellite image validation system with in situ data collected over a distributed sensor network of ground validation sites. The Gridded Atmospheric product will be validated with long term continuous observed data from Phonological Eyes Network (PEN) The success of this study will contribute to validate MODIS satellite products, and to improve the accuracy of higher level products.

It aims at providing a geographic UI to complex relationships between our partners and their customers. Simplicity Reusability In order to improve robustness and reusability, we based our project on standard blocks (PostGIS, GeoServer, OpenLayers) with limited and well defined connections between them. Geoserver produces OGC geographic webservices which are being used by OpenLayers. They can also be re used by any OGC compliant application such as desktop GIS for instance. This supports EDF R&D policy to provide the company with geographic data by means of webservices. Look and Feel Since the key to user acceptance for a new application is ergonomy, we took a special care for the UI design. Accordingly, we chose a well known client library: MapFish client, exploiting ExtJS and GeoExt Librairies. Discussion The development of Prospar's prototype brought into question the technical choices we made at the very beginning of the project, namely: the use of distinct applicative blocks loosely connected vs integrated frameworks such as MapFish or GeoDjango. These frameworks offer more versatility, but, as a drawback, are stronger coupled with a spatial database (PostGIS being
