| 3 | To add the cartography functionality, edit the file dysoweb.properties located in the folder tomcat/webapps/dysoweb/WEB-INF/classes: |
| 4 | |
| 5 | * add ",\" at the end of the last row. |
| 6 | * then add the row "com.almworks.sqlite4java" atthe end of the file. |
| 7 | |
| 8 | Edit the file requeadb.xml located in dysoweb.home/config by adding the row : |
| 9 | <DbSpatial>true</DbSpatial> |
| 10 | |
| 11 | In the Requea interface, go to the menu System Parameters in the item l’onglet Administrator and modify these two parameters: |
| 12 | |
| 13 | * com.requea.osm.tiles.path : inform the path to the .mbtiles file |
| 14 | * com.requea.dynapage.geospatial.geomap : put the value OSM |

| 16 | = Use Cartography = |
| 17 | To display items on the map, you have to create an entity with a property type //spacial Geometry// and the format //2D Geodetic property// : |

| 19 | |
| 20 | To view the map from the .mbtiles file, create an entity derived from GeoMapView: |
| 21 | [[image:Capturedecran2015-06-01a17.54.55.png]] |
| 22 | |
| 23 | Modify the script of the field Display rules or behavior in the properties sysView and sysZoom so that it point to your preferred location: |

| 27 | [[image:Capturedecran2015-06-01a17.55.38.png]] |
| 28 | |
| 29 | To display items on that map, edit the operation BuildMap with a script. |

| 31 | For example: |
| 32 | |
| 33 | {{code language="javascript"}} |
| 34 | var map = {}; |
| 35 | map.layers = []; |
| 36 | var layer; |
| 37 | |
| 38 | layer = {}; |
| 39 | layer.title = "Items"; |
| 40 | layer.points = []; |
| 41 | layer.layers = []; |
| 42 | |
| 43 | var centerX = 0; |
| 44 | var centerY = 0; |
| 45 | var nb = 0; |
| 46 | var flt = new Filter("seItem"); |
| 47 | |
| 48 | var iter = flt.search(); |
| 49 | |
| 50 | while(iter.hasNext()) { |
| 51 | var item = iter.next(); |
| 52 | var pos = item.seGeoPosition; |
| 53 | |
| 54 | if(pos != null) { |
| 55 | if(nb == 0) { |
| 56 | centerX = pos.x; |
| 57 | centerY = pos.y; |
| 58 | nb = 1; |
| 59 | } else { |
| 60 | centerX = (pos.x + nb * centerX) / ( nb+1 ); |
| 61 | centerY = (pos.y + nb * centerY) / ( nb+1 ); |
| 62 | nb ++; |
| 63 | } |
| 64 | } |
| 65 | } |
| 66 | map.layers.push(layer); |
| 67 | |
| 68 | data = new Json(map); |
| 69 | } |
