Space

Use cases

• In an agricultural management system, you can use a device map to configure a geospatial space. This provides a map-based overview of your asset distribution (for example, enterprises, farm bases, processing points, agricultural supply stores, and trading markets), helping you analyze the development prospects of the agricultural industry.
• During the growing season, you can monitor and collect data on crop growth and soil conditions. Using the device map and space features, you can display the growth and soil conditions for different crops across various areas on a map. By comparing this data with data from previous years, you can predict the impact on the current season's crop yields in different regions.

Add a space

1. On the project details page, click Spaces in the left navigation pane, and then click Add Space.
   Note The space must be in the same project as the web visualization application that contains the device map.
2. On the Create Space page, click Draw Space, select a drawing method from the drop-down list, and follow the on-screen instructions to draw the geospatial area.
   The supported drawing methods are Circle, Polygon, Administrative Region, and Code Text. The supported encoding formats for Code Text are as follows:

   • WKT text: A text markup language for representing vector geometry objects on a map. For more information, see WKT.
   • GeoJSON text: A JSON-based geospatial data interchange format for expressing geographic features, properties, and spatial extents. For more information, see GeoJSON.
     Note When you use GeoJSON text, FeatureCollection is not supported. Only Polygon and MultiPolygon are supported.

   On the Create Space page, click the Draw Space drop-down button to select a drawing method. For example, if you select Polygon, click at least three points on the map, and then right-click to finish drawing.
3. Click the drawn space to enter edit mode. Follow the on-screen prompts to adjust the final boundaries of the space.
   Follow the instructions at the bottom of the page: drag the anchor points to edit the space, and click an area on the map outside the space to finish editing. If you need to start over, click Redraw in the upper-right corner.
4. Click Next, and then set the space name and description.
5. Click Next to add properties for the space. These properties act as labels for the space.
   1. Enter a property identifier and a display name.
   2. Optional: Select the Add to all spaces in the current project checkbox.
   3. Click Add Property.
      The new property is displayed in the property list. You can delete any added properties.
6. Click Finish.
   After the space is created, it appears in the space list on the Spaces page.
7. Optional: Click View in List. On the Spaces page, you can perform the following operations.
   • In a global resource project: You can add, edit (redraw a space, set space information and properties), or delete spaces. New spaces created in any common project under your account are automatically imported.
   • In a common project: You can add, edit, delete, or unbind spaces. You can also associate any space from a global resource project.

   The space list displays the space name, description, type, thumbnail, and creation time for each space in a table. You can search by space name or description.

Associate a space with a common project

1. On the Spaces page of a common project, click Associate Space.
2. On the Associate Space page, select the checkbox next to the name of the space you want to associate.
   Note Already associated spaces do not appear in the space list.
3. Click OK.
   The project's Spaces page now lists the associated space.
