Operations Dashboard - map image or feature layer

marcomontrasio — Tue, 27 Apr 2021 09:01:00 GMT

Hi everyone,

i'm trying to create an Operation Dashboard.

i wanna display the map and some list and charts aside that. So far so good, now i want link the list with the map, all work if I've imported the layers as feature ones but the problem is that is extremely slow, otherwise if I import layers as Map image it's quicker enough but there's no way to connect the list with the map.

so i've two questions:

1) is there any restriction on link list/chats with the map image layer?

2) is there a way to improve the velocity if I use feature layer?

Thanks a lot in advance,

Marco

If the service has enabled data access, you can make a chart, but getting the chart to link to the map may depend on other settings. In general, even when I can get a map image to link between a chart and map, the behavior is inconsistent. Best to go with a Feature Layer if you want to pan / flash / filter on the map.
There are lots of ways to improve the speed, but it will really depend on your situation and the intended use of your dashboard.
- Set scale visibility limits on the layer
- Set a filter on the chart / list item to only show a subset of important items
- Have the list / chart filter based on the map extent
- Define a layer view and set an AOI / view definition
- Use a Map Image layer at small scales for display purposes, but switch to features once you zoom in further

What does your layer look like, can I ask? And what are you making the dashboard for? There might be other ways around this, depending on the specifics. And are you working in AGOL or Enterprise?

Thanks for your answer.

I should create an application for road intervention that could help visualize all of them, able to filter on some particular field. For a small scale I wanna see a polygon layer but if I zoom out I displayed as Point. At the moment that I start to zoom in and the polygon appears, start to go slowly.
