Flynn // -Initial release // -Includes Geozone support // 2008/10/16 Martin D. Flynn // -Initial support for GeoServer // 2010/04/11 Martin D. Flynn // -Added support for drawing polygon and corridor geozones. However, in the // case of corridor geozones, additional GTS features may be required to // fully utilize this type of geozone. // 2012/04/03 Martin D. Flynn // -Updated map layer creation interface // -Added support for MapQuest OSM/Arial layers // 2013/08/06 Martin D. Flynn // -Fixed spelling, renamed "Arial" to "Aerial" // ---------------------------------------------------------------------------- package org.opengts.war.maps.jsmap; import java.util.*; import java.io.*; import org.opengts.util.*; import org.opengts.db.tables.Geozone; import org.opengts.war.tools.*; import org.opengts.war.maps.JSMap; public class OpenLayers extends JSMap { // ------------------------------------------------------------------------ /* OpenLayers JavaScript URL */ private static final String OPENLAYERS_JS_URL = "http://openlayers.org/api/OpenLayers.js"; // ------------------------------------------------------------------------ /* SitiMapa support properties */ public static final String PROP_SITIMAPA_enable[] = new String[] { "sitiMapa.enable" }; /* GeoServer support properties */ public static final String PROP_GEOSERVER_enable[] = new String[] { "geoServer.enable" }; public static final String PROP_GEOSERVER_title[] = new String[] { "geoServer.title" }; public static final String PROP_GEOSERVER_url[] = new String[] { "geoServer.url" }; public static final String PROP_GEOSERVER_maxResolution[] = new String[] { "geoServer.maxResolution" }; public static final String PROP_GEOSERVER_size[] = new String[] { "geoServer.size" }; public static final String PROP_GEOSERVER_projection[] = new String[] { "geoServer.projection" }; public static final String PROP_GEOSERVER_layers[] = new String[] { "geoServer.layers" }; public static final String PROP_GEOSERVER_bounds[] = new String[] { "geoServer.bounds" }; public static final String PROP_GEOSERVER_units[] = new String[] { "geoServer.units" }; public static final String PROP_GEOSERVER_layerType[] = new String[] { "geoServer.layerType" }; /* Mapquest layers */ public static final String PROP_MAPQUEST_showOSMLayer[] = new String[] { "mapQuest.enableLayer.osm" }; public static final String PROP_MAPQUEST_showAerialLayer[] = new String[] { "mapQuest.enableLayer.aerial", "mapQuest.enableLayer.arial" }; // ------------------------------------------------------------------------ private static final int DEFAULT_ZOOM = 4; // ------------------------------------------------------------------------ // ------------------------------------------------------------------------ /* OpenLayers instance */ public OpenLayers(String name, String key) { super(name, key); this.addSupportedFeature(FEATURE_LATLON_DISPLAY); this.addSupportedFeature(FEATURE_DISTANCE_RULER); this.addSupportedFeature(FEATURE_GEOZONES); this.addSupportedFeature(FEATURE_DETAIL_REPORT); this.addSupportedFeature(FEATURE_DETAIL_INFO_BOX); this.addSupportedFeature(FEATURE_REPLAY_POINTS); this.addSupportedFeature(FEATURE_CENTER_ON_LAST); this.addSupportedFeature(FEATURE_CORRIDORS); } // ------------------------------------------------------------------------ /* write mapping support JS to stream */ protected void writeJSVariables(PrintWriter out, RequestProperties reqState) throws IOException { super.writeJSVariables(out, reqState); out.write("// OpenLayers custom vars\n"); RTProperties rtp = this.getProperties(); // GeoServer support boolean gsEnable = rtp.getBoolean(PROP_GEOSERVER_enable, false); JavaScriptTools.writeJSVar(out, "GEOSERVER_enable", gsEnable); if (gsEnable) { String gsTitle = StringTools.blankDefault(rtp.getString(PROP_GEOSERVER_title,null), "WMS Provider"); String gsURL = rtp.getString(PROP_GEOSERVER_url, ""); String gsMaxRes = StringTools.blankDefault(rtp.getString(PROP_GEOSERVER_maxResolution,null), "auto"); String gsSize = StringTools.blankDefault(rtp.getString(PROP_GEOSERVER_size,null), "{ width:0, height:0 }"); String gsProj = StringTools.blankDefault(rtp.getString(PROP_GEOSERVER_projection,null), "EPSG:4326"); String gsLayers = rtp.getString(PROP_GEOSERVER_layers, ""); String gsBounds = StringTools.blankDefault(rtp.getString(PROP_GEOSERVER_bounds,null), "{ top:0, left:0, bottom:0, right:0 }"); String gsUnits = StringTools.blankDefault(rtp.getString(PROP_GEOSERVER_units,null), "degrees"); String gsLayerT = StringTools.blankDefault(rtp.getString(PROP_GEOSERVER_layerType,null), "tiled"); JavaScriptTools.writeJSVar(out, "GEOSERVER_title" , gsTitle); JavaScriptTools.writeJSVar(out, "GEOSERVER_url" , gsURL); JavaScriptTools.writeJSVar(out, "GEOSERVER_maxResolution", gsMaxRes, !StringTools.isDouble(gsMaxRes,true)); JavaScriptTools.writeJSVar(out, "GEOSERVER_size" , gsSize , false); JavaScriptTools.writeJSVar(out, "GEOSERVER_projection" , gsProj); JavaScriptTools.writeJSVar(out, "GEOSERVER_layers" , gsLayers); JavaScriptTools.writeJSVar(out, "GEOSERVER_bounds" , gsBounds, false); JavaScriptTools.writeJSVar(out, "GEOSERVER_units" , gsUnits); JavaScriptTools.writeJSVar(out, "GEOSERVER_layerType" , gsLayerT); } // SitiMapa boolean smEnable = !gsEnable?
