Marker Display

[geoffreymuchai]

• Display markers at country zoom.
• Put a single map marker at the location when there is PECS data for that country for that round. To do this you'll just need to take a lat and long from the PECS data and copy and paste it in the lat, long column in the hki-vas-data.csv.
• After that we'll need it so we see the individual points (red / green) or heatmap. This should load dynamically when you click on the point and zoom in.

Current Progress

Display of single markers and individual points for Cameroon data works but the other datapoints do not render on the map when loaded through omnivore.

Still to be done

• highlight each individual point as red or green based on the vita value or implement a heatmap to display the data.
• Investigate why the other datapoints in data/pecs do not load.

Current progress:

• Pecs data points are now displayed when you zoom in but I need to find out an intelligent way of determining which file to load based on the country a user is zooming into. @mberg if you have an idea on how to get the country code using leaflet's api, that will be a time saver for me.
• modified the map markers to use the pharmacy icon as direct by Matt.

Pending issue:

• At the moment, the only pecs data file that is successfully loaded is the Cameroon data. I need to investigate why the other pecs data files are not loaded by omnivore.
• Loading of the right pecs data file based on the country a user is zooming into.

@geoffreymuchai to answer a few of your q's.

Take a look at the zoomToFeature function. I think we'll want to do that when you click the marker. What you would pass to it is the layer and do a bounds around that.

It's a bit tricky as we'll need to make sure the layer disappears when we change rounds and zoom out. So I think basing this off of the zoom level will be key. We also don't want to load all the points across all sites for a round as we'd be loading 9 points per site.

On the omnivore issue I really am not sure what the issue is. Have you tried loading a different single data set? Did that work? Or is only a problem when you are loading multiple datasets at once.

Couple of other things missing

• it needs to change depending on the indicator selected
• the map markers in red and green work pretty well. I changed it to small and it works better. We may want to try and draw a circle to see if it looks better. I'm going to tweak the colors too to be a bit more pronounced.

I just looked at the PECS data layer and realized we only have data for vita and also for gender and age. I just pushed up code that distinguishes by gender (m/f). Maybe we want to add a toggle that does age group (1/2).

I can't really see much difference though so maybe just focusing on vita as a single parameter is enough. i'm trying to see if we can get heatmap working to see if it helps make better sense of what's going on.

The data points now look better thanks to the improvements you have made. I will look into the zoomToFeature implementation you have suggested and will factor in the expected behaviour.

Concerning the omnivore issue, I have tried loading different data sets yesterday but it hasn't worked. I will investigate further to find out what could be causing this.

@mberg I now have most of the other data pecs points loading. I had to rename some of them to match the expected code_hasc code.

The reason omnivore was not loading the files is because the files contained rows which had invalid values in the latitude and longitude columns.

yep that's what i figured. looking at it now. beautiful!
