Saving a map

How to Save maps?

One of the great features of the GeoHub is the ability to save maps by applying the visualizations and analytics that the user desires after they have logged in.

Requirements

To save a map requires at least a layer needs to be added into the map.

1.Selct a layer of choice at Data tab or Datasets page by following the steps of the search datasets section, then clicking on the add layer button or the icon Add_remove_layer_icon.png icon.

2.Go to the Layers tab where you can change the layer appearance by using the steps you have learned in the previous section.

Note

As we have mentioned at the earlier sections, there are two types of datasets either raster or vector. The way of visualizing is slightly different. Please follow the steps of vector visualization here and raster visualization here

For example, the following figure is an example map which I made.

An example map to visualize the location and density of water facilities on digital elevation model at Eastern Province of Rwanda
Figure 1: An example map to visualize the location and density of water facilities on digital elevation model at Eastern Province of Rwanda

I made a map by the following points.

--

  • added Digital Elevation Model (DEM) 10m resolution, Rwanda. But I rescaled it by 1180 and 2261 because I want to make them clear in the area of interest.
  • added water facilities in Rwanda data as a heatmap layer. I changed opacity to 30% to make DEM data visible together with heatmap.
  • added water facilities in Rwanda data as a circle layer. I visualized circle color by Wsf Type property and adjusted color make them more visible.

Rwanda is known as a country of thousand of hills. Understanding how its landscape is quite important for policy making. This map now can show how water facilties were maped in the Eastern Province of Rwanda against elevations. I renamed title to Location and density of water facilities on digital elevation model at Eastern Province of Rwanda

Now, it is ready to save your map.

Steps to save a map

1.Click on the Map_Share.png icon to SHARE or UPDATE the map.

2.A pop up box (shown in the below figure) opens with selections for renaming the map to your liking.

Note

As default, it will show the first layer's title as a map name. But it is recommended for you to rename more precise and appealing map title. So, it will become easier for other users to search your map and understand the concept of your visualization. You can still rename this title anytime later.

3.Select the accessibility for map sharing as either only the user, UNDP email holder or Public.

Note

Like the dataset accessiblity, you can also select an accesibility for your map. As default, Your name (private map) is selected. If you are from UN agencies, you may find your organization name like UNDP here. An organization name is selected, only signed in users in your organization can access to your map. If you feel like your map is ready to be published to anyone else, you can select Public accessiblity. The accessiblity can be changed anytime later.

4.Then click on the "Share" button to complete the process or cancel to restart. If you opened an existing map, the button name will become UPDATE.

5.The dialog will show an URL to share with your colleagues after you have clicked SHARE button as shown in the below figure. You can simply click Copy button to copy the URL to your clipboard to share it with your colleagues.

Next step

In the next section, you are going to learn more about sharing a map. If you still open the dialog of Update map in GeoHub, click save_map_example_4.png. This button will open your saved map as new tab. Then continue the next section.
