DHIS2 Maps

A map answers where, while a chart answers how much and when. There are two ways to start one. From the Data Visualizer, the selection you already made can be sent straight to the map. Or open the Maps app and build from nothing.

1

1. 1Open as Map. Takes the data, period and organisation unit you chose in Topic 7 into the Maps app.

The Maps app is built from layers. One layer draws the data, another draws the background.

1. 1Add layer. Everything on the map starts here.
2. 2The layer. Its name and the period it shows.
3. 3The legend. The colour for each range, and how many units fall in it.
4. 4Layer tools. Edit the layer, hide it, change how see through it is, and the menu for more.
5. 5Basemap. The background map. OSM Light is the plainest and usually the best for reports.
6. 6Map controls. Zoom, reset, full screen and search.
7. 7File. New, open, save, share and delete.
8. 8Download. Turns the map into a picture you can put in a report.

Click Add layer. The list holds far more than the coloured districts most people expect.

1. 1Thematic. Districts or chiefdoms coloured by a value. This is the one this guide builds.
2. 2Events. One dot per event, for tracker and event programmes.
3. 3Facilities. The facilities themselves, with their icons.
4. 4Org units. Just the boundaries, with no data.
5. 5Population. From Earth Engine, useful as a denominator you do not have.
6. 6Precipitation and temperature. Also from Earth Engine, which matters for malaria seasons.

The thematic layer window has five tabs, and they are the same four choices as a chart plus the styling.

1. 1Data. What to map. Data elements, indicators, data sets or event data.
2. 2Period. Last 12 months, this year, or a fixed month.
3. 3Org Units. Choose a level, such as District or Chiefdom. This is what gets coloured.
4. 4Style. The colours, the number of classes and the legend.
5. 5Data Type. Indicators here, because a rate compares fairly between districts.
6. 6The list. ANC 3 Coverage is the example. Click the arrow to move it to the right.
7. 7Selected Items. One item per thematic layer.
8. 8Add layer. Draws the layer on the map.

The map colours every unit at the level you chose. Read the legend before reading the colours, because the ranges decide the story.

1. 1The layer. Its name and period, which appear on the dashboard as well.
2. 2The ranges. Low to great, with the number of districts in each range in brackets.
3. 3The count. A zero in brackets means no district falls in that range.
4. 4Transparency. Slide it when the basemap underneath needs to show through.
5. 5Zoom. Plus, minus and reset. Double clicking a district zooms to it.
6. 6Scale. Always check it before using the picture in a report.

A map has to be saved before it can be put on a dashboard, exactly like a chart.

1. 1File. Opens this menu.
2. 2Save. Saves changes to a map that already has a name.
3. 3Save as. Makes a new map, which is what you want the first time.
4. 4Get link. A link straight to this map, useful in an email.
5. 5Delete. Removes the map for everyone it was shared with.

1. 1Name. What it shows, the level and the period, for example ANC 3 Coverage by district, last 12 months.
2. 2Description. One line on what the map is for. It appears beside the map on the dashboard.
3. 3Save. Saves the map, ready for the dashboard.

For a report or a slide, turn the map into an image. Download mode adds the parts a printed map needs.

1. 1Show map name. The title on the picture.
2. 2Show legend. Never leave this out. A map without a legend cannot be read.
3. 3Show overview map. The small map that says where in the world this is.
4. 4Show north arrow. With four positions to choose from.
5. 5Download. Saves the picture to your computer.
6. 6The title and description. Taken from what you typed when saving.
7. 7The legend. Both layers appear, so remove the ones you do not need first.
