| − | == About ==
| |
| − | | |
| − | QGIS-Plugin '''ArcGIS REST API Connector''' which reads from ArcGIS Online and ArcGIS Server and the "Esri Open Data Initiative Portal Software".
| |
| − | | |
| − | Currently reading "Feature Services" (similar to [[WFS]] but proprietary) and "Map Services" (kind of [[WMTS]]) are supported.
| |
| − | | |
| − | This plugin focusses on '''reading''' so-called '''"Maps"''' accessible without restrictions over the Internet by interpreting JSON (JavaScript Object Notation) and image output formats.
| |
| − | | |
| − | Functions (similar to WFS) "Add ArcGIS REST Layer...":
| |
| − | * connect/new/edit/delete connection
| |
| − | * load/save connections
| |
| − | * filter layer list
| |
| − | * select layer (then download)
| |
| − | | |
| − | Implementation details of Feature Service:
| |
| − | * maxRecordCount - currently maxRecordCount is ignored.
| |
| − | * Query - currently there's no query functionality.
| |
| − | * outSR - currently geometry is returned as default well-known ID "GCS_WGS_1984".
| |
| − | | |
| − | Map services expose a set of tiled images, read-only, working with the default data frame of the published map document on the server.

| − | According to Esri's specification of [http://resources.arcgis.com/en/help/arcgis-rest-api/index.html#/The_ArcGIS_REST_API/02r300000054000000/ "ArcGIS REST API"]], there are many services: ''... With ready-to-use basemaps, reference layers, and so on, you can quickly add context or a backdrop to your local or worldwide data. Some ArcGIS Online maps are thematic, which may provide all the information you need to present in your application''.
| |
| − | | |
| − | Future improvements may be made to Feature Service, Map Service and additionally to a new Image Service, which provides access to raster data similar to Map Services. Both Map and Image services return raster images mosaicked on the fly or WMTS whereas the main difference is that Map Services are read-only while Image Service include an API for editing and uploading (which is out-of-scope of this plugin).
| |
| − | | |
| − | General improvements may include
| |
| − | * Authentification (with OAuth 2.0)
| |
| − | * Image Service.
| |
| − | * HttpProxy ([https://github.com/geometalab/ArcGISConnector-QGIS-Plugin/issues/3 issue])
| |
| − | | |
| − | Future improvements of Feature Service may include:
| |
| − | * Paging (maxRecordCount)
| |
| − | * Local Feature Cache (see [http://resources.arcgis.com/en/help/main/10.2/index.html#/Managing_your_local_display_cache/006600000180000000/])
| |
| − | * Dealing with compressed http content
| |
| − | * Reading/showing "Services Directory"
| |
| − | * Query and Query Related Records
| |
| − | | |
| − | Future improvements of Map Service may include:
| |
| − | * Feature (aka OGC WMS GetFeatureInfo?)
| |
| − | * Image (Marker)?
| |
| − | * Legend (aka WMS GetLegend)
| |
| − | * Map Tile
| |
| − | * WMTS
