WaPOR, remote sensing for water productivity

How to use WaPOR

 

We are working to make WaPOR interactive maps simple to use and to navigate. If you’re a new user, follow these steps, using the icons identified by the numbers in the image above:

1. Explore available Layers and time range: scroll down the list of layers, select one and define the temporal parameters. Click "Select" to load the layer on the map.

2. Browse the Catalogue to explore all layers organized by categories. Then select a theme to read its description and metadata. By selecting the filters of interest (year, season, dekad) and - for the national level - the country or basin of interest, the selected data can be accessed through OGC link (wms) or downloaded. Go back to the map to continue exploring WaPOR.

3. Locate a place on the map by typing name or geographical coordinates in lat, lon. The point will be shown on the map and a text box will appear describing the layer value for that point. If you’re logged in, you will have the option to save the point in your "MyWaPOR" area.

4. Use the Analysis tools. You will have to be signed in to access these functionalities. There are currently four types of analyses supported by WaPOR: Point and Area Time Series, Area Water Productivity and Area Raster Download. Users are asked to specify the Layer, the Place and the Parameters to run the analysis. For area based operations, users can either draw a polygon on the map or upload a shapefile. In this latter case, please note that the compressed file (zip) should contain at least 3 files (XXX.shp, XXX.shx, XXX.dbf) and that, if the shapefile contains more than one polygon, only the first feature will be used to run the analysis.

5. Find more About WaPOR: version number, contact email and additional resources available from here.

6. Sign in using the top right "Sign in" link: you will be asked to either use your own Google account, or create a new account in WaPOR portal. In this latter case, please type in a valid email address and create your own password for accessing WaPOR portal. A confirmation email will be sent to you to activate your profile.

7. Transparency slider. This is particularly useful if you’re using a background layer (see next point)

8. Access other map Options, including selection of Base Layer (like OpenStreet Map) and the possibility to overlay country and hydrological basin boundaries.
