Adding ArcGIS Online Services to QGIS?

Question

Looking for info on how to add web mapping services from the Ohio Department of Natural Resources website to QGIS. I've tried nearly a dozen different things online and still can't get results. Don't normally ask for help in places like this, but decided to attempt this route for fear that it was impossible (permissions issues, etc.). Link to data I want to add is posted below:

Answer 1

QGIS 2.16 / 2.18 / 3.00:

1. Layer - Add Layer - Add ArcGIS FeatureServer Layer...
2. New (for a new connection). Give a name and enter https://gis.ohiodnr.gov/arcgis/rest/services/OIT_Services/odnr_landbase/MapServer/ in field URL.
3. Connect (connect to service to fetch layers).
4. Select layer. For example Current Township.
5. Add.

QGIS 2.14:

1. Install ArcGIS REST API Connector plugin. (a. Plugins - Manage and install plugins... b. Tab Settings. c. Mark checkbox Show also experimental plugins. d. Tab All. e. Search for ArcGIS, select and install ArcGIS REST API Connector plugin.)
2. Hit the ArcGIS icon in the Manage Layers Toolbar.
3. Enter the layer URL in field Layer URL. https://gis.ohiodnr.gov/arcgis/rest/services/OIT_Services/odnr_landbase/MapServer/2 Layernumber is important!
4. Put cursor in field Layer Name. If Layer URL is correct Layer Name will show up.
5. Connect to add features to QGIS.

When I checked the data, not all layers worked well.

• Counties: QGIS 2.16.0 gave me a crash. FME failed, log said No resultsPython Exception : fmeobjects.FMEGeometry or None is required FME said 0 features. The same layer in the V3 service did work and gave me 164 features.
• Historic_Township: 1365 features
• Current_Township: 1330 features
• Land_Subdivision: QGIS 2.16.0 gave me a crash. FME failed, log said No resultsPython Exception : fmeobjects.FMEGeometry or None is required. FME said 29917 features.
• Statewide_Parcels: QGIS 2.16.0 gave me a crash. FME failed, log said Encountered an unexpected error. The error code from the server was '500' and the message was: 'Error performing query operation'. Details: ''

With QGIS 2.18 there are huge improvements in connecting to an ArcGIS Server map service. Use the Layer > Add Layer > Add ArcGIS MapServer Layer.. command. I just blogged about this yesterday. The complete steps are:

1. Copy the URL of the map service. The URL must end with "/MapServer": https://gis.ohiodnr.gov/arcgis/rest/services/OIT_Services/odnr_landbase/MapServer
2. Open QGIS
3. Go to Layer > Add Layer > Add ArcGIS MapServer Layer..
4. In the Dialog box click the "New" button
5. In the "Create a new ArcGISMapServer connection" window enter the name "ODNR Landbase" and paste the URL from Step 1 into the URL field and click the "OK" button
6. Click the "Connect" button and the layers from the map service will be displayed
7. Select/highlight the layers in the list that you want to ad to your QGIS project and click the "Add" button

You can use a tool called Add ArcGIS Map Server Layer. To get the tool just find menu Layer >> Add Layer >> Add ArcGIS Map Server Layer... See the tutorial How to use ArcGIS REST API Service in QGIS
