Why create a geospatial representation of subregions?
If your project area consists of several sections with different characteristics, you can create a polygon for each subarea, which are stored together in a single map layer.
Examples of subregions:
- Administrative boundaries, such as counties, regions, provinces, etc.
- Differences in ownership
- Differences in land use or management regimes
- Different habitats or biozones
How to create a geospatial representation of subregions
Navigate to https://geojson.io/.
Draw several polygons on the map. See this article for instructions on drawing a polygon.
Click on the "Table" tab in the top right of the screen.
Click "New Column" and name it "
NAME"(singular, all in capitals). This is the Sensing Clues standard for geospatial objects representing subregions.
In the table that appears, click on a row and the map will zoom to the corresponding polygon.
Fill in a value for each row.
Return to the "JSON" tab. You will find the added information under
properties.
Download your object so that it can be shared or loaded into geospatial software. Select "GeoJSON" from the "Save" menu at the top left of the map.
The map layer will appear in your download folder as "
map.geojson". Please give it a more descriptive file name.Send the file to hello@sensingclues.org (including your name and organisation) or upload it to your personal GeoJSON folder via the Sensing Clues Upload Service.
