Shapefiles Show Raster DataIf you have a georeferenced image or aerial imagery, you will need to import them using the Add Raster Layer button. To import a raster file, follow these steps:
CSV fileOnce the csv files are formatted properly, you can add them into QGIS.
If you want to use spatial data that you created in nodegoat in a geographic information system (GIS) application like QGIS, you can export your data as a CSV file or query the nodegoat API. In both cases, you end up with one or multiple files that you then can process and work with in a GIS application. In this guide we will describe a more dynamic approach: use the Python console in QGIS to pull in data from your nodegoat environment. This approach allows you to use nodegoat as your primary data store and instantly update your QGIS project whenever you want to load in the most recent version of your data. To make this work, first configure the API of your research environment in such a way that you can run queries to fetch the spatial data you want to use in your GIS application. You should have enabled at least one project in the API settings, and you should have configured at least one active client and one active user who has access to the enabled project. The identifiers of Objects, Object Types, Scopes, or Filters (and any other nodegoat element) are shown under the name of the element when you edit or view the element in nodegoat. You will use these identifiers to construct the API queries. If you do not have access to the API module that can be accessed via 'Management', please contact the administrator of your nodegoat environment or send a message to . Before you start querying the API from your GIS application, it is recommended to first run your query as a cURL command to confirm that the requested data is correctly returned. For example:
Connect QGIS to nodegoatTo use the response data in QGIS: start a new project and go to 'Plugins > Python Console'. Click the 'Show Editor' button in order to be able to write and run a python script. The first section of the script fetches your data from the nodegoat API:
Next, create a point layer that can host the returned data:
Finally, iterate over the returned Objects and Sub-Objects in order to add the geometry data to the newly created layer:
Paste these three sections of the script in the editor. Click the 'Run Script' button to fetch and display your nodegoat data in your QGIS project. Enable the 'Show Labels' option to display the returned Object Names as labels. To include geometries of related Objects, you set a Scope that follows a reference to a related Object Type containing spatial data. Follow the guide 'Manage your Visualisation' to learn more about the Scope functionality. Store this Scope and use its identifier in your query, e.g.: 'https://nodegoat.io/data/type/[Your Object Type ID]/scope/[Your Scope ID]/object'. Update the part of the scripts that iterates over the Objects and Sub-Objects to this:
How do I export coordinates from GIS?(1) On the menu bar, select Vector -> Geometry Tools -> Extract Vertices. A popup box will ask which layer you wish to extract nodes from, and how you want to save the new layer. Click OK, and a new points-only layer should appear.
How do I export shapefile coordinates?Export coordinates. Click the Export button in the Coordinate Conversion pane.. Click the button for the format to which to export the collected coordinates—this could be feature class, shapefile, KMZ, or CSV—and click OK.. Browse to the location where you want to store the output and click Save.. How do I create a point file in QGIS?Map Coordinates with QGIS
Click the down arrow next to the icon and select “add new shapefile” from the options. From the pop-up window select point. You can also change the coordinate system (the default is the set coordinate system of your QGIS file) and add any attribute fields you want. Hit the “ok” button.
