Map Vector Tile Item
Pick out one map feature when several overlap at the spot you tapped.
Tap a busy part of the map and more than one feature can sit under your finger — a camera pin, a boundary, a road segment, a marked area. This card collects everything found at that point and groups it by the map layer it came from, so you can open the layer you meant and choose the exact feature. Each group lists its features as numbered points.
Overview
| Element | What it does |
|---|---|
| Header | Title area at the top of the card; it stays blank because the groups below carry the labels |
| Source group header | The layer name followed by how many features it found, for example source (3) |
| Group arrow | Points down when the group is open, right when it is closed |
| Point row | One feature inside the group, labeled Point 1, Point 2, and so on in the order they were found |
| Done button | Closes the card without choosing anything |
All groups start closed, so the card first shows you a summary: which layers were hit, and how many features each one has. The card sizes itself to the number of groups and features, so a tap that finds one feature in one layer opens a small card, and a tap in a dense area opens a taller one.
Features are grouped by the map layer that published them, not by what they look like. Two pins that look identical can sit in different groups if they come from different layers.
Getting Here
- From Home, open References then Video Streams.
- Switch to the Map tab.
- Tap a spot where several map features overlap.
- The card opens listing every feature found at that point.
The same card appears on the other map screens in the app whenever a tap lands on more than one feature.
Reading the Groups
- Each group header names a map layer and shows its feature count in parentheses.
- The count tells you how crowded that spot is in that layer — a count of 1 means your tap was precise, and a higher count means you will need to pick.
- Groups are listed in the order the layers were queried, not alphabetically, so the order can differ from one tap to the next.
Expanding a Source Group
- Tap a group header to expand it. Its points appear underneath.
- Tap the header again to collapse it.
- The arrow flips between pointing down (open) and right (closed).
- You can open more than one group at a time, which is useful when you are not sure which layer holds the feature you want.
Selecting a Point
- Expand the group that should contain the feature you want.
- Tap the Point row you are interested in — for example Point 2.
- The card closes, that feature becomes the map's selected feature, and its information is handed back to the map for display.
Point rows are only numbered, so there is no way to tell them apart before you open one. When you are not sure, open them one at a time: selecting a point closes the card and shows its details, and tapping the same spot on the map again brings this card straight back.
Closing the Card
- Tap Done to close the card without selecting a feature.
- Nothing on the map changes, and the previously selected feature stays selected.
What Counts as a Feature
"Feature" covers anything a map layer draws, which is why one tap can turn up such a mixed list.
| Feature you might hit | Why it is under your finger |
|---|---|
| A camera or location pin | Pins are drawn with a tap area larger than the icon itself |
| A boundary or zone shape | Any tap inside the shape counts as a hit |
| A road or line | Lines have a tap area a few pixels wide on each side |
| An area fill | The whole filled area is tappable |
| A label | Labels belong to their layer and can be hit on their own |
| The count on a group | Usually means |
|---|---|
| 1 | A clean hit on one feature in that layer |
| 2 or 3 | Features drawn close together, or a pin sitting on a shape |
| Many | You tapped inside a shape that also carries several points, or a dense point layer |
Working a Dense Map Efficiently
The card is quick to use once you treat it as a filter rather than a list.
- Read the counts first. They tell you instantly whether your tap was precise or landed in a pile.
- Open only the layer you care about. If you were looking for a boundary, ignore the pin layers entirely.
- Zoom in and tap again when every group shows a high count. A closer zoom usually reduces a tap to one or two features.
- Pick, look, come back. Selecting a point closes the card. Tapping the same spot again reopens it with the same groups, so working through several features is just repeat taps.
| Symptom | Better approach |
|---|---|
| Every group shows a big count | Zoom in two or three steps and tap again |
| The layer you want is missing | Check your map layer settings, then tap again |
| You keep hitting the same wrong feature | Tap slightly off center, or zoom in first |
| You need several features from one spot | Open them one at a time, reopening the card between each |
What the Card Does Not Do
| You might expect | Reality |
|---|---|
| Point names or previews | Rows are numbered only — Point 1, Point 2, and so on |
| A search field | None; the card is meant for a handful of features |
| Multi-select | None; picking a point closes the card |
| Sorting or reordering | None; groups and points appear in the order they were found |
| A count of all features across layers | Each group carries its own count; there is no total |
| Anything editable | Nothing here changes the map or the features |
Because rows carry no names, the group header is your only clue about what a point is. A group name that reads like a camera layer tells you the points are camera pins; a boundary layer tells you they are shapes.
How This Connects
- Where the features come from. Everything in this card is drawn from the map layers already loaded in your current map view — the card does not fetch anything new, it just reports what was rendered under your tap. Change the layers or the zoom and the same tap gives a different list.
- What happens after you pick. The selected feature's own attributes are passed to the detail card described in Stream Preview, where names are tidied up and sorted so they read cleanly. Features that carry a color also get the color and opacity button there.
- Camera pins use a different list. When your tap lands on overlapping camera pins or on a cluster of them, the app opens Video Stream Map Item instead, which lists cameras by name rather than as numbered points.
- Shared with the map screens. The same overlap handling, layer grouping, and selection behavior applies on Reference Map and on the maps inside an incident, see Incident Maps Tab. Which layers are available to be tapped is controlled by Map Style Options.
- Offline and reconnect. The card works on whatever is already drawn, so it still opens with no signal. Layers that had not finished loading before you lost the connection simply will not appear in the list.
Troubleshooting
| If this happens | What to do |
|---|---|
| The card does not appear at all | Your tap landed on empty map, or on a single feature — a single hit opens that feature's details directly. |
| A group shows a count but no rows when opened | Collapse and expand the group again; if it stays empty, close the card with Done and tap the same spot again. |
| You cannot tell which point is which | Open them one at a time. Reopen the card by tapping the same spot again after each look. |
| The layer you wanted is not listed | That layer was not under your tap, or it is switched off. Check your map layer settings and zoom in before tapping again. |
| The card is too tall to read | Scroll inside the card, or collapse the groups you do not need. |
| You picked the wrong point | Tap the same spot on the map again and choose a different point. |
