6.4.4. Resource view
After login to administrative interface the user is taken to home page shown on Pic. 6.8..
You can open the Update resource dialog by clicking the pencil icon next to the resource, or delete a resource directly from the list. For special types of resources other actions are available (e.g. Preview for vector layers or Open for Web Maps).
To open a resource page click on the corresponding row of the table. The resource page contains properties, attributes, a link for external access and a list of child resources if there are any (see Pic. 6.9.).
Here you can also enter the resource edit mode.
6.4.5. Feature table
Some resources contain a set of features that can be viewed as a table. Press the “Table” icon opposite the resource name or select an action for a vector layer called “Table” in the features pane.
Feature table allows to perform the following operations with a selected feature (see Pic. 6.12.):
Open
Edit (in a new tab or in the same tab)
Delete
Save as (advanced or quick export available)
Use Search Box
Refresh the table
Open table settings
There is another way to open Feature table. In the adminitrative interface navigate to a child resource group where resource types are marked and find a resource with a type Web Map. Open it by clicking on the “Display” icon (see Pic. 6.13.):
Alternatively, you can go to the resource page and click “Display” in the Web Map actions pane on the right.
A Web Map will be opened with a layer tree (left) and a map (right). To view a feature table select the required layer in layer tree and then select “Feature table” command in the Layer drop down menu at the top of layer tree Pic. 6.15.:
A table will be displayed in a new tab. Table allows to perform the following operations with the selected feature Pic. 6.16.:
Open in a new tab
Edit
Delete
Go to (after a click the selected feature will be displayed on the map)
Save as (advanced or quick export available)
Zoom to filtered features
7. Filter features by area 5. Use Search Box 6. Refresh the table 7. Open table settings
You can also edit the attributes themselves.
6.4.5.1. Filter layer features on the Web Map by area
NextGIS Web has a tool in the Feature table that filters all layer features within a selected area. To choose area limits just draw them on the Web Map.
Open the feature table and click on the button with a dotted frame. In the dropdown menu select the geometry of the area:
circle (click twice on the map, to choose the center of the circle and its size, the radius length is shown in meters)
line (features intersected by the line will be filtered)
rectangle (click on diagonally opposite apexes)
free-hand drawn polygon (each click creates an apex, the area covered by the polygon is highlighted; to finish the shape, double-click on an apex, the polygon will be completed automatically)
Now the feature table only contains the features within the selected area. The tool button will have the current area shape on it. In the dropdown menu you can use one of the following options:
Show/Hide the outline and fill of the selected area
Zoom to the filtering area
Clear filtering geometry
You can use quick export to save the filtered features in a variety of common geodata formats. Click Save as and select in the dropdown menu Quick export with default settings or Advanced export to modify parameters (see detailed description below).
6.4.6. Data export
NextGIS Web allows you to export data in the following formats:
CSV for Microsoft Excel
AutoCAD DXF
Mapinfo TAB
MapInfo MIF/MID
While exporting to some formats additional files are created, for example CSVT (field description) and PRJ (projection description) for CSV, CPG (code page) for ESRI Shapefile.
To export data:
Open a Vector or PostGIS layer, the data of which you want to export;
Select the item: menuselection: Features -> Save As on the right pane :ref:` web interface <ngw_admin_interface> `;
Specify the format and encoding of the data and select fields to be exported;
If necessary, you can compress the result into a ZIP archive (for a number of formats this is the default setting);
Save the file to your device.
