Display of local trends

[Nhorning]

I've had a request of two organizations, DFID and UN BOGS, for a feature that can show incident trends in local districts of Nepal.

This feature would somehow allow users to filter reports by a local area in addition to other filters and display the results on a timeline.

There are obviously multiple ways to implement this feature with varying difficulty, complexity and usefulness. I'll include a few suggestions.

1. Filter by screen borders: This would likely consist of a tick box in the "enhanced map" plugin that would filter the reports being tracked to only those visible on the screen. This would allow a user to zoom in on a district an see a timeline graph of only those reports visible in the district.
2. Add a timeline graph to the public "reports" page. This would allow people to use the "filter by location" feature to filter reports into a local area and then display a trend. There are disadvantages to this implementation, because it does not allow for an easily printable map like the "enhanced map" plugin, and there is currently (Ushahidi 2.5) a bug in the "filter by location" feature that prevents more than one page of reports from being displayed. There is also not a way in Ushahidi 2.5 to display KML layers on the map used by the "filter by location" feature.
3. Filter by boarders of KML file: Probably the most useful implementation would be the ability to filter by the boarders within elements of a KML Layer. This could be implemented on the main page, or the "Big Map" or both. When I click on the KML layer for one of my district, I get a "talk box" which gives me the name of the district. This talk box could contain a link - "Filter reports by this region" and then doing so would filter the reports by the region and adjust the timeline graph accordingly.
4. Others pending.

Hi @Nhorning

Did you look at the densitymap plugin? it does something like 3. grouping of reports based on a KML file.
Maybe you could extend that plugin?

The "bug in the "filter by location" feature that prevents more than one page of reports from being displayed" is actually design. The /reports page shows everything page by page. However I agree that UI often isn't useful

Hi Robbie,

Thanks for letting me know about the plugin. I'll check it out. Is it
really by design that the reports count at the top of the screen goes to
"0" and the additional pages are inaccessible when filtering by
location, is it also by design that the dots don't display on the "map"
tab when filtering by location? To be clear, the problem isn't that only
one page displays at a time, the problem is that only one page is
accessible. If you can't reproduce locally try my deployment:

Ah sorry - I thought you meant it was a bug that reports were displayed page by page on the map.
What you're describing sounds like a bug that was in 2.6, fixed in 2.6.1 - try upgrading?

[Nhorning]

Fair enough. I'd like to anyway, but I can't take the risk of breaking
my deployment such as in the last two upgrades at the moment. I have to
present a working system to some other agencies. I'll work on that when
there is some calm. Thanks for responding to all of these issues.

OK Fair enough.
If you're coming from 2.6.. 2.6.1 release is literally ONLY bug fixes. at a minimum you may want to consider applying the security patch.. more details here:

I would definitely consider that if I weren't still using 2.5. :)

Hi, We have @himalayantechies working with us for a month. Hopefully they'll be able to do something on this

[Nhorning]

@himalayantechies has created a plugin which largely fulfills this feature request: https://github.com/HTSolution/Ushahidi-plugin-kmlfilter

I've added this to the V3 feature comments at https://phabricator.ushahidi.com/T49; please feel free to continue working on this for V2.
