Evaluacin y creacin de un geo visor Septiembre 19 de 2014

Introduccin Basado en el documento Geovisor.pdf, proporcionado en clase por el docente, se desarrolla un Geovisor bsico, siguiendo las pautas establecidas en el documento antes mencionado.

Resultados El resultado de aplicar y seguir las instrucciones en las primeras 4 secciones (Introduccin, Requerimientos, Configuracin, Diseo de Interfaz y los primeros 4 puntos de la seccin Adicin de datos) se pueden observar en el archivo pom.xml (que se muestra como un anexo de este documento) configurado correctamente y en hecho de que los puntos subsiguientes funcionan adecuadamente Los resultados que se muestran a continuacin corresponden, como se mencion anteriormente a los puntos asociados a la seccin Adicin de datos. 5.- Despliegue de las Manzanas File shpManz = new File("datos\\Manz.shp"); FileDataStore fdsManz = FileDataStoreFinder.getDataStore(shpManz); SimpleFeatureSource sfsManz = fdsManz.getFeatureSource(); org.geotools.styling.Style stlManz = SLD.createSimpleStyle(sfsManz.getSchema()); Layer lyrManz = new FeatureLayer(sfsManz, stlManz); cont.addLayer(lyrManz);



6.- Usabilidad: para lo que se tiene de manera inicial, los botones muestran metforas adecuadas. Quizs sean algo grandes, desperdiciando espacio. NO hay un botn para salir, no se pueden adicionar, por interfaz ms capas, no hay forma de adicionar capas desde bases de datos



7.- Adicionar capas de drenaje y vas // Capa Drenaje File shpDren = new File("datos\\Dren.shp"); FileDataStore fdsDren = FileDataStoreFinder.getDataStore(shpDren); SimpleFeatureSource sfsDren = fdsDren.getFeatureSource(); org.geotools.styling.Style stlDren = SLD.createSimpleStyle(sfsDren.getSchema()); Layer lyrDren = new FeatureLayer(sfsDren, stlDren); cont.addLayer(lyrDren); // Capa Malla Vial Integral File shpMVI = new File("datos\\MVI.shp"); FileDataStore fdsMVI = FileDataStoreFinder.getDataStore(shpMVI); SimpleFeatureSource sfsMVI = fdsMVI.getFeatureSource(); org.geotools.styling.Style stlMVI = SLD.createSimpleStyle(sfsMVI.getSchema()); Layer lyrMVI = new FeatureLayer(sfsMVI, stlMVI); cont.addLayer(lyrMVI);



8.- Adicionar bsqueda de shape /* Trabajar con cualquier shape */ // display a data store file chooser dialog for shapefiles File shpGeneric = JFileDataStoreChooser.showOpenFile("shp", null); if (shpGeneric == null) { return; } FileDataStore fdsGeneric = FileDataStoreFinder.getDataStore(shpGeneric); SimpleFeatureSource sfsGeneric = fdsGeneric.getFeatureSource(); org.geotools.styling.Style stlGeneric = SLD.createSimpleStyle(sfsGeneric.getSchema()); Layer lyrGeneric = new FeatureLayer(sfsGeneric, stlGeneric); cont.addLayer(lyrGeneric);

Adicionar botn /* Adicionar un boton a la barra de herramientas*/ JToolBar toolBar = map.getToolBar(); //JButton btn = new JButton("Select"); Icon btnIcon = new ImageIcon("imgs\\AddLayer.jpg"); JButton btn = new JButton(btnIcon); toolBar.addSeparator(); toolBar.add(btn);



9.- Implemente un botn para agregar capas //Boton para adicionar nuevas capas Icon btnIcon = new ImageIcon("imgs\\AddLayer30.jpg"); final JButton btn = new JButton(btnIcon); btn.setToolTipText("Adicionar capa"); toolBar.add(btn); map.setVisible(true); // Tareas del boton btn.addActionListener ( new ActionListener () { @SuppressWarnings("empty-statement") @Override public void actionPerformed (ActionEvent ae) { try { File shpGenerico = JFileDataStoreChooser.showOpenFile ("shp", null); if (shpGenerico == null) { return; } FileDataStore fdsGenerico = FileDataStoreFinder.getDataStore (shpGenerico); SimpleFeatureSource sfsGenerico = fdsGenerico.getFeatureSource (); org.geotools.styling.Style stlGenerico = SLD.createSimpleStyle(sfsGenerico.getSchema()); Layer lyrGenerico = new FeatureLayer (sfsGenerico, stlGenerico); cont.addLayer(lyrGenerico); } catch (IOException e){System.out.println("e");}; } } );



10.- Cargue las localidades en la base de datos postgreSQL



11.- Adicionar gt-jdbc-postgis al pom.xml y resolver dependencias Adicionar una nueva dependecia en al archivo pom.xml org.geotools.jdbc gt-jdbc-postgis ${geotools.version} Cargar dependencias declaradas



12.- Parmetros Map params = new HashMap(); params.put("dbtype", "postgis"); params.put("host", "localhost"); params.put("port", 5432 ); params.put("schema", "public"); params.put("database", "Bogota"); params.put("user", "postgres"); params.put("passwd", "postgres2014");



13.- Mostrar capa leyendo desde PostGres // Add the layer Localidades from PostGres DataStore dsPG = DataStoreFinder.getDataStore(params); FeatureSource fsLoc = dsPG.getFeatureSource("localidades"); org.geotools.styling.Style stlLoc = SLD.createSimpleStyle(fsLoc.getSchema()); Layer lyrLoc = new FeatureLayer(fsLoc, stlLoc); cont.addLayer(lyrLoc); map.setVisible(true);



14.- Crear botn para cargar localidades desde Postgres

Conclusiones

Geotools como API para desarrollar aplicaciones de manera rpida, acorde al conocimiento

que de la librera se tenga

Se siguieron las instrucciones planteadas en el documento gua, con algunas aclaraciones

como la ubicacin de los fragmentos de cdigo a adicionar en cada paso dentro del cdigo

principal, url para carga de la librera gt-jdbc-postgis y la declaracin de variable public static

Para mejorar la usabilidad se adicion un botn para Salir de la aplicacin, validacin de solo

nmeros para el campo Puerto, uso de metforas en los iconos de los botones adicionados

(Add Layer, Add Layer from Database y Exit) y finalmente uso de texto de ayuda acorde al

contexto en los botones para reforzar la funcionalidad proporcionada por cada botn
