Geodatabase Development to Support Hyperspectral Imagery Exploitation
Geodatabase development for coastal studies conducted by the Naval Research Laboratory (NRL) is essential to support the exploitation of hyperspectral imagery (HSI). NRL has found that the remote sensing and mapping science community benefits from coastal classifications that group coastal types based on similar features. Selected features in project geodatabases relate to significant biological and physical forces that shape the coast. The project geodatabases help researchers understand factors that are necessary for imagery post processing, especially those features having a high degree of temporal and spatial variability. NRL project geodatabases include a hierarchy of environmental factors that extend from shallow water bottom types and beach composition to inland soil and vegetation characteristics. These geodatabases developed by NRL allow researchers to compare features among coast types. The project geodatabases may also be used to enhance littoral data archives that are sparse. This paper highlights geodatabase development for recent remote sensing experiments in barrier island, coral, and mangrove coast types
Design of the shared Environmental Information System (SEIS) and development of a web-based GIS interface
Chapter 5The Shared Environmental Information System (SEIS) is a collaborative initiative of
the European Commission (EC) and the European Environment Agency (EEA) aimed to
establish an integrated and shared EU-wide environmental information system together
with the Member States.
SEIS presents the European vision on environmental information interoperability. It is
a set of high-level principles & workflow-processes that organize the collection, exchange,
and use of environmental data & information aimed to:
• Modernise the way in which information required by environmental legislation is
made available to member states or EC instruments;
• Streamline reporting processes and repeal overlaps or obsolete reporting obligations;
• Stimulate similar developments at international conventions;
• Standardise according to INSPIRE when possible; and
• Introduce the SDI (spatial database infrastructure) principle EU-wide.
SEIS is a system and workflow of operations that offers technical capabilities geared to
meet concept expectations. In that respect, SEIS shows the way and sets up the workflow
effectively in a standardise way (e.g, INSPIRE) to:
• Collect Data from Spatial Databases, in situ sensors, statistical databases, earth
observation readings (e.g., EOS, GMES), marine observation using standard data
transfer protocols (ODBC, SOS, ft p, etc).
• Harmonise collected data (including data check/data integrity) according to best
practices proven to perform well, according to the INSPIRE Directive 2007/2/EC
(1) Annexes I: II: III: plus INSPIRE Implementation Rules for data not specified in
above mentioned Annexes.
• Harmonise collected data according to WISE (Water Information System from
Europe) or Ozone-web.
• Process, aggregate harmonise data so to extract information in a format understandable
by wider audiences (e.g., Eurostat, enviro-indicators).
• Document information to fulfi l national reporting obligations towards EU bodies
(e.g., the JRC, EEA, DGENV, Eurostat)
• Store and publish information for authorised end-users (e.g., citizens, institutions).

Managing Water Network using GIS
The purpose and the goal of the paper are to introduce a framework based on onto Geographical information systems (GIS) to integrate geographic information of Urban areas taking Khartoum State as an example. One of the main characteristics of such a framework is to support the information integration and data exchange between facilities using the base maps to solve the problem of distributing water networks. Entities in the Khartoum State (KS) infrastructure link information sources and lead to integration and exchange of associated information. The Methodology used is to study the existing urban systems specially water network using Geodatabase concept which are analyzed by observing and comparing the related earlier work using different criteria.  The Geodatabase of the system was defined , designed and build ArcGIS software. An object oriented geodatabase was created using GIS Software ,then the information was gathered from Water, Sewage, Transportation Corporations in Khartoum States. The tools and software used are the Style Studio 2009 XML. Enterprise Suite Editor for driving KS Infrastructure geodatabase and KS Digital Base map was obtained from Khartoum State Surveying Corporation for Khartoum city center. Visual Basic for Application (VBA) was used to develop the Search Engine program. The main result obtained by the research is the development of a framework based on Geodatabase concept for the integration of geographic information of Khartoum State infrastructure network facilities.  The geodatabase of Khartoum State base map and facilities networks were completed by creating Multitask object oriented geodatabase using ArCatalog. A search engine code was written and tested ninety presents successful. The integration of information was available to exchange information between different Corporations to solve any problem that may damage the network facilities and to help managing and adding any new services on the site. The paper recommends the Building of multi-user unified geodatabase connected to a wide area network to service the concerned enterprise. Keywords: GIS; Geodatabse , Water Network ,ArcGIS , KS ,GM

Advancement of a Soil Parameters Geodatabase for the Modeling Assessment of Conservation Practice Outcomes in the United States
US-ModSoilParms-TEMPLE is a database composed of a set of geographic databases functionally storing soil-spatial units and soil hydraulic, physical, and chemical parameters for three agriculture management simulation models, SWAT, APEX, and ALMANAC. This paper introduces the updated US-ModSoilParms-TEMPLE, which covers the entire United States and is organized as a framework of 22 nested and hydrologically-ordered regional geographic databases with internal spatial segmentation drainage-defined at a conveniently manageable tile (Watershed Boundary Dataset’s, WBD, 8-digit Subbasin) level. Spatial features are stored in multiple formats (raster and vector) and resolutions (10-meter and 30-meter), while being in direct relationship with the table of attributes storing the models’ parameters.
A significant number of former parameter voids, determined by the local incompleteness of the source datasets, were filled using a methodology leveraging upon the hierarchy of the Soil Taxonomy information and the geographic location of the gaps. The functionality of each geographic database was extended by adding customized tools, which streamline the incorporation into geoprocessing workflows, the aggregation and extraction of data sets, and finally the export to other model support software user environments. These tools are attached and conveniently distributed along with detailed metadata documentation within each of the developed regional geographic databases. The system hosting this framework is developed using a proprietary software format (ESRI® File Geodatabase), however, a companion version of the framework of 8-digit tiles is also developed and provided using openly accessible formats. The experience shared in this paper might help other efforts in developing hydrology-oriented geographical databases
PrePro2004: a data model with pre and post-processor for HEC-HMS
This thesis presents the design concepts and development of an interface (Pre-
Pro2004) utilizing geodatabases for the Hydrologic Modeling System (HMS) of the
Hydrologic Engineering Center (HEC). HMS is a rainfall-runoff model which supports
lumped-parameter as well as distributed-parameter based modeling. PrePro2004 uses the
spatial-analysis as well as data handling capabilities of ArcGIS. The spatial data are processed
to create input files for HMS. These input files and the output from HMS are stored
in two geodatabases which were developed using data model concepts. The tools are provided
to reproduce an HMS model from the data inside these geodatabases. The interface
is developed based on the DataCentric approach which brings different hydrologic and
hydraulic models together. This approach aims to attain a long-term goal of utilizing the
same data for different hydrologic or hydraulic models with additional model specific
requirements.
Two case studies are presented to show the applications of the tools developed. The
first case study details the creation of HMS input files for Salado Creek watershed with
Digital Elevation Model as input. It includes the importation of an existing HMS model
for Salado Creek watershed as Appendix C. The second case study details the creation of
HMS input files for the Bull Creek watershed, with land use and soil type data as inputs.
It describes the capabilities of tools developed in detail
A highly detailed land-use vector map for Madrid region based on photo-interpretation
Land Use – Land Cover (LULC) maps have developed remarkably since the global community became aware of the importance of knowing where LULC change is taking place on the Earth's surface. The rapid evolution of geographic information data handling and the automation of satellite image interpretation through remote sensing techniques and algorithms is providing increasingly abundant and up-to-date information on LULC. In addition, at large detail scales, it is important to link LULC maps to available statistical information, such as census information and business activities, which allow land parcels to be more accurately classified. Though automated classification methods can produce useful maps at smaller detail scales, it is not usually possible to accurately map urban areas at large scales without considerable investment of human resources. The development of large-scale information for urban areas is very important, especially in urban areas with accelerated rates of urban change which may jeopardize natural resources and citizens’ quality of life. In this paper, the creation of a set of large detail scale LULC maps and accompanying geodatabase for one such dynamic urban change region, the Madrid Autonomous Community (AC), Spain, is discussed
