Workshop GRASS GIS and RDBMS
Workshop W-11 GRASS GIS and RDBMS Workshop GRASS GIS and RDBMS by Marco Ciolli, Paolo Zatelli and Clara Tattoni Department of Civil and Environmental Engineering University of Trento Italy FOSS4G2007 Victoria, Canada 24-27 September 2007 Workshop W-11 GRASS GIS and RDBMS GGIISS aanndd DDBBMMSS GISs can manage all the features of geographic information: geometry, topology and attributes. Sometimes it is more efficient to manage some or all of these features with an external Data Base Management System (DBMS). A DBMS can manage the attributes, a DBMS with spatial extension can manage the geometry as well. It is possible to use different DBMS, databases and configurations for different maps in the same dataset or for different layers of the same map. FOSS4G2007 Victoria, Canada 24-27 September 2007 2 Workshop W-11 GRASS GIS and RDBMS GGRRAASSSS,, QQGGIISS aanndd DDBBMMSS GRASS and QGIS can read all formats supported by the OGR library, that is data from the more used DBMS If using OGR Library with GRASS, data can be: – imported (GRASS native format) – linked as read-only external data with pseudotopology (v.external) FOSS4G2007 Victoria, Canada 24-27 September 2007 3 Workshop W-11 GRASS GIS and RDBMS QQGGIISS aanndd DDBBMMSS QGIS can access directly PostgreSQL/PostGIS data both attributes and geometry. In order to use a PostgreSQL/PostGIS layer in QGIS, it must be present a key column of int4. This layer processing speed can be enhanced by indexing that column (if it is a PostgreSQL primary key it is indexed by default). If a view is used, it must contain a type int4 column or a primary key, possibly indexed.

INTERNATIONAL EXPERTS’ MEETING ON ASSESSMENT AND PROGNOSIS IN RESPONSE TO A NUCLEAR OR RADIOLOGICAL EMERGENCY (CN-256) IAEA Headquarters Vienna, Austria 20–24 April 2015 Context In nuclear disaster affecting agriculture, there is a need for rapid, reliable and practical tools and techniques to assess any release of radioactivity The research of hazards illustrates how geographic information is being integrated into solutions and the important role the Web now plays in communication and disseminating information to the public for mitigation, management, and recovery from a disaster. 2 Context Basically GIS is used to provide user with spatial information. In the case of the traditional GIS, these types of information are within the system or group of systems. Hence, this disadvantage of traditional GIS led to develop a solution of integrating GIS and Internet, which is called Web-GIS. 3 Project Goal CRP1.50.15: “ Response to Nuclear Emergency affecting Food and Agriculture” The specific objective of our contribution is to design a prototype of web based mapping application that should be able to: 1.

Building a Spatial Database in Postgresql
Building a Spatial Database in PostgreSQL David Blasby Refractions Research [email protected] http://postgis.refractions.net Introduction • PostGIS is a spatial extension for PostgreSQL • PostGIS aims to be an “OpenGIS Simple Features for SQL” compliant spatial database • I am the principal developer Topics of Discussion • Spatial data and spatial databases • Adding spatial extensions to PostgreSQL • OpenGIS and standards Why PostGIS? • There aren’t any good open source spatial databases available • commercial ones are very expensive • Aren’t any open source spatial functions • extremely difficult to properly code • building block for any spatial project • Enable information to be organized, visualized, and analyzed like never before What is a Spatial Database? Database that: • Stores spatial objects • Manipulates spatial objects just like other objects in the database What is Spatial data? • Data which describes either location or shape e.g.House or Fire Hydrant location Roads, Rivers, Pipelines, Power lines Forests, Parks, Municipalities, Lakes What is Spatial data? • In the abstract, reductionist view of the computer, these entities are represented as Points, Lines, and Polygons. Roads are represented as Lines Mail Boxes are represented as Points Topic Three Land Use Classifications are represented as Polygons Topic Three Combination of all the previous data Spatial Relationships • Not just interested in location, also interested in “Relationships” between objects that are very hard to model outside the spatial domain. • The most

Web GIS has put GIS on Web, that made it available to common public which was earlier used by few elite users. In the present paper, development of Web GIS frameworks has been explained that provide the requisite knowledge for creating Web based GIS applications. Open Source Software (OSS) have been used to develop two Web GIS frameworks. In first Web GIS framework, WAMP server, ALOV, Quantum GIS and MySQL have been used while in second Web GIS framework, Apache Tomcat server, GeoServer, Quantum GIS, PostgreSQL and PostGIS have been used. These two Web GIS frameworks have been critically compared to bring out the suitability of each for a particular application as well as their performance. This will assist users in selecting the most suitable one for a particular Web GIS application. 1.

The Decision Table Template for Geospatial Business Rules
The Decision Table Template For Geospatial Business Rules Alex Karman CTO and Co-Founder Revolutionary Machines, Inc. www.rev-mac.com San Jose, Oct 13-15, 2014 1 OpenRules Now Supports Spatial Rules • Leverages the popular JTS Topology Suite (“JTS”) • Supports the Egenhofer Relationships (“DE9-IM”) for 2D points, polygons and line strings – Contains, touches, crosses, overlaps, disjoint, etc. • Supports distance and area calculations; and ranking by distance or area • Supports aggregates (max/min) of spatial rules • Supports non-spatial mereological rules – Part of/comprises • Loads Geographic Markup Language (GML) from text files with a GeometryDatabaseBuilder utility Motivation • Last year, we used OpenRules to handle business rules related to security constraints and service level agreements in a data center management project. • This year, the customer asked us if OpenRules could manage fraud detection and privacy rules in a healthcare project in the same data center. • We looked at the problem domain and saw a large number of spatial rules. Spatial Business Rules Are Everywhere • Healthcare – Hospital Referral Region, Hospital Service Area, Hospital, Patient, Emergency Routes • Sales – Supplier and buyer territories, census block demographics • Utilities – Markets are usually defined geographically • Local government – Cadasters, zones, counties, municipalities Most Spatial Business Rules Only Require a Simple Vocabulary • Describe how simple points, polygons and lines interact • Describe distances between them • Describe “at least” or “no more than” rules (aggregate spatial rules) Most Spatial Business Rules Never Use Most GIS Features • Continuous field data – Weather, climate, netCDF, raster • Slope and aspect – Digital elevation model, bathymetry, viewshed • Topology – The shoreline borders the shore • Spatial statistics – Autocorrelation, Moran’s I, Geary’s C, etc.
