Dans sa version 1994-2000, les orthophotos sont accompagnées d'un maillage. Il s'agit d'un découpage de la Wallonie en mailles polygonales de 2 km x 2,5 km de côté ayant comme origine la coordonnée (0,0). Il est propre au Service public de Wallonie. Des données attributaires sont associées à chaque maille du maillage. Les orthophotos sont disponibles, entre autres, sous forme d\u2019images (au format Geotiff, pour les plus récentes) de la dimension d\u2019une maille.\n\nL\u2019ensemble des fichiers images appartenant à une feuille IGN au 1/50 000 est groupé dans un même dossier portant le numéro de la feuille.\n\nLe maillage peut être utilisé pour connaitre la date de prise de vue de la photographie associée et pour faciliter la recherche du fichier image correspondant au sein de l\u2019arborescence du disque.\n\nConsultez toutes les informations sur cette donnée sur : http://geoportail.wallonie.be/geocatalogue?mdUUID=6f924476-d62c-4f1c-bc9a-03e1d9f06424", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 31370, "latestWkid": 31370 }, "copyrightText": "SPW", "parentLayer": null, "subLayers": [], "minScale": 1500000, "maxScale": 250, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 0, 0, 0, 0 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 255, 0, 0, 255 ], "width": 0.4 } }, "label": "", "description": "" }, "transparency": 0, "labelingInfo": null }, "defaultVisibility": true, "extent": { "xmin": 30000, "ymin": 15000, "xmax": 310000, "ymax": 200000, "spatialReference": { "wkid": 31370, "latestWkid": 31370 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "IMAGE_NAME", "typeIdField": null, "subtypeFieldName": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "IMAGE_NAME", "type": "esriFieldTypeString", "alias": "Nom du fichier image", "length": 30, "domain": null }, { "name": "DATE_FIRST", "type": "esriFieldTypeDate", "alias": "Première date de vol", "length": 8, "domain": null }, { "name": "DATE_LAST", "type": "esriFieldTypeDate", "alias": "Dernière date de vol", "length": 8, "domain": null }, { "name": "PX_X_SIZE", "type": "esriFieldTypeDouble", "alias": "Taille du pixel en X (m)", "domain": null }, { "name": "PX_Y_SIZE", "type": "esriFieldTypeDouble", "alias": "Taille du pixel en Y (m)", "domain": null }, { "name": "BANDS", "type": "esriFieldTypeInteger", "alias": "Nombre de canaux", "domain": null }, { "name": "RADIO_RES", "type": "esriFieldTypeInteger", "alias": "Résolution radiométrique", "domain": null }, { "name": "IMG_WIDTH", "type": "esriFieldTypeInteger", "alias": "Largeur de l\u2019image (pixels)", "domain": null }, { "name": "IMG_HEIGHT", "type": "esriFieldTypeInteger", "alias": "Hauteur de l\u2019image (pixels)", "domain": null }, { "name": "LOW_LEFT_X", "type": "esriFieldTypeInteger", "alias": "Origine maille X (m)", "domain": null }, { "name": "LOW_LEFT_Y", "type": "esriFieldTypeInteger", "alias": "Origine maille Y (m)", "domain": null }, { "name": "COORD_SYST", "type": "esriFieldTypeString", "alias": "Système de coordonnées", "length": 50, "domain": null }, { "name": "EPSG", "type": "esriFieldTypeInteger", "alias": "EPSG", "domain": null }, { "name": "PROVIDER", "type": "esriFieldTypeString", "alias": "Fournisseur", "length": 30, "domain": null }, { "name": "MAPSHEET", "type": "esriFieldTypeString", "alias": "Feuille IGN", "length": 3, "domain": null }, { "name": "IMG_SCALE", "type": "esriFieldTypeDouble", "alias": "Echelle de l'image", "domain": null }, { "name": "IMG_RES", "type": "esriFieldTypeString", "alias": "IMG_RES", "length": 16, "domain": null }, { "name": "GEOM", "type": "esriFieldTypeGeometry", "alias": "GEOM", "domain": null } ], "indexes": [ { "name": "SPW_1994_2000_MAILLAGE_SIDX", "fields": "GEOM", "isAscending": true, "isUnique": true, "description": "" } ], "subtypes": [], "relationships": [], "canModifyLayer": false, "canScaleSymbols": true, "hasLabels": false, "capabilities": "Map,Query,Data", "maxRecordCount": 1000, "supportsStatistics": true, "supportsAdvancedQueries": true, "supportedQueryFormats": "JSON, AMF, geoJSON", "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsPagination": true, "supportsTrueCurve": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": true }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null }
