Note:
The ArcGIS Collector help site is retired and no longer being updated. To learn about ArcGIS Collector retirement and to find the latest information on data collection, see Collector retirement.
Collector allows you to capture asset inventories and observations in the field. Each asset and observation you capture has both a location and a form. You'll provide the location and fill out the form.
Note:
If you're inspecting, updating, or editing existing assets or observations, see Inspect.
| Are you at the location of the asset or observation? | |
|---|---|
   | Capture an asset or observation you can be at, such as a hydrant, pipeline, or football field. This is useful when a length or area has straight sections. Use your location to define the ends of straight sections and Collector connects them. Supported for single places, lengths, and areas. |
Capture at your location with GPS averaging  | Take multiple GPS readings and average the values to get a more precise location. This is common in high-accuracy workflows, such as capturing the location of an underground valve. Supported for single places, lengths, and areas. |
Capture automatically while walking or driving the length or boundary (streaming)   | Capture an asset or observation you can be at that is a smooth line or has a smooth boundary, such as a path or flower bed. Use your location as you walk or drive the length or boundary to create smooth sections matching the shape of the asset or observation. Supported for lengths and areas. |
Copy an existing asset or observation to your location  | Capture an asset or observation with the same form as an existing one—the form matches and can be updated. This is useful when capturing the same or similar things, such as a row of newly planted spruce trees. Supported for single places, lengths, and areas. |
Capture at a location offset from your location  | Capture an asset or observation you can see but not be at while measuring how far away you are with a laser rangefinder. For example, you are capturing the building corners but need centimeter accuracy and can't obtain it while against the building. Supported for single places, lengths, and areas. |
| Are you using the map to find the location? | |
|---|---|
Capture at a location chosen on the map   | Capture an asset or observation you can see but not be at, such as a damaged building when the location must be placed at the structure, or a flooded field. Use the map and its basemap or reference layers to place points. Lengths and areas use the points to define the ends of straight sections and Collector connects them. Supported for single places, lengths, and areas. Tip:If you only need to measure a length or area and not create an item on the map, use the measure tool. |
| Do you have the coordinates of the asset or observation? | |
|---|---|
Capture at a coordinate location  | Capture an asset or observation at known coordinates. Examples include a location radioed during a search and rescue mission or weather observations from a handheld weather meter. Supported for single places or the first point of a length or area. |
| Is the location the same as that of an existing asset or observation? | |
|---|---|
Capture using an existing asset or observation's location  | Capture at the same location as an existing asset or observation, sharing the location but getting a new, empty form. For example, use the location of a post when capturing its signs. Supported for single places. |
| Are you copying an existing asset or observation? | |
|---|---|
Copy an existing asset or observation  | Copy an existing asset or observation, sharing the location and form. For example, copy a road to use it for managing repaving. Supported on single places, lengths, and areas that are read-only or only allow attribute updates. |
| Are you capturing an asset or observation you want related to an existing asset or observation? | |
|---|---|
Capture an asset or observation from the form of an existing related asset or observation  | Capture an asset or observation that is related to an existing asset or observation. You can use your location or choose a location on the map. For example, readings taken along a pipeline are often associated with the pipe but have their own location along it. Supported for single places, lengths, and areas. |
At your location
You are at the location of the asset or observation you want to capture. Use the GPS to capture its location.
- Open the map of your assets or observations.
- Tap Add
.The location target appears on the map, centered on your location.
- Choose the type of asset or observation to capture.
Note:
If you're not prompted to choose, you only have a single type available, and it is selected automatically.
The asset or observation (or its first point, if it's a length or area) is placed on the map at your location (assuming your GPS accuracy is within the limits you've set), marked by the location target. If the circle of the location target is red, your location accuracy isn't good enough (based on your required accuracy setting), and you must override the accuracy by tapping Add point, manually place the point, or wait for better accuracy. Once placed, the point doesn't move as your GPS location updates.
- If you need to update the location, you can do so either using the GPS or manually.
- To manually set the location, move the map so that your desired location is under the location target.
- To use the GPS, tap the GPS button
and the location target is centered on your location.
Tap Update point (Update selected point from the Overflow menu
for lengths and areas) and the point moves to the current position of the location target. - If you're capturing a length or area, move to the next place you want to add a point (the location target follows you) and tap Add point. Repeat until your asset or observation's location is complete.
Tip:
You can manually place a point on the map by moving the map so that your desired location is under the location target and tapping Add point. To center the location target over your location again, tap the GPS button
.You can also stream sections of the asset, if desired. Use Start streaming (in the Overflow menu
) to create a section of the asset by traveling along it. Tap Stop streaming to continue to place points without streaming. See At your location while traveling (streaming).If you need to place a point with an offset from your location, see Offset from your location.
- Fill out the form, including adding any attachments (photos, videos, or audio files).
- Tap Submit once your asset or observation is ready.
Your asset or observation is on the map and its form displays in the panel. If you're working online, others immediately have access to your edits. If you're working offline, your edits are available to others once you sync them.
At your location with GPS averaging
You are at the location of the asset or observation you want to capture. Capture multiple GPS points and average them to capture its location.
- Enable GPS averaging in the settings in Collector.
- Open the map of your assets or observations.
- Tap Add .
The location target appears on the map, centered on your location.
- Choose the type of asset or observation to capture.
Note:
If you're not prompted to choose, you only have a single type available, and it is selected automatically.
GPS averaging begins, and once the required number of locations are captured, the asset or observation (or its first point, if it's a length or area) is placed at the averaged location on the map.
- If you need to update the location, tap Start averaging (for single places) or Update selected point (in the Overflow menu for lengths and areas) to redo the GPS averaging and calculate a new location.
Tip:
If you pan away from your GPS location, you can tap Update point (Add point for lengths and areas) and tap Use target location to add a point at that location on the map. To use GPS averaging instead, tap Update point (Add point for lengths and areas) and tap Start averaging.
- If you're capturing a length or area, move to the next place you want to add a point (the location target follows you) and tap Add point. Repeat until your asset or observation's location is complete. An average is calculated when placing each point.
Tip:
You can also stream sections of the asset, if desired. Use Start streaming (in the Overflow menu
) to create a section of the asset by traveling along it. Tap Stop streaming to continue to place points without streaming. See At your location while traveling (streaming). - Fill out the form, including adding any attachments (photos, videos, or audio files).
- Tap Submit once your asset or observation is ready.
Your asset or observation is on the map and its form displays in the panel. If you're working online, others immediately have access to your edits. If you're working offline, your edits are available to others once you sync them.
At your location while traveling (streaming)
Walk or drive along the asset or observation you are capturing and create its geometry based on your path. By automatically adding points based on the time or distance since the last point was added, you create the location by traveling along it instead of adding each point manually. This involves less hands-on interaction, but it can also result in less-accurate locations (for example, when rounding corners).
Note:
Streaming to collect lengths and areas and GPS averaging are mutually exclusive: you can't average the values and stream at the same time.
- Open the map of your assets or observations.
- Tap Add .
The location target appears on the map, centered on your location.
- Choose the type of asset or observation to capture.
Note:
If you're not prompted to choose, you only have a single type available, and it is selected automatically.
The first point is added to the location of the asset or observation at your location (assuming your GPS accuracy is within the limits you've set), marked by the location target. If the circle of the location target is red, your location accuracy isn't good enough (based on your required accuracy setting), and you must override the accuracy by tapping Add point, manually place the point, or wait for better accuracy. Once placed, the point doesn't move as your GPS location updates.
- From the Overflow menu , tap Start streaming.
The location target is removed from the map and the blue GPS dot displays. The first streamed point is placed on the map at your current location (assuming your GPS accuracy is within the limits you've set).
- Walk or drive along or around the asset or observation.
As your GPS location updates, additional points are added to the location. The frequency at which they are added depends on the streaming settings.
While you are streaming, you can't manually add or update points. To do so, stop streaming, make your updates, and start streaming again.
- Fill out the form, including adding any attachments (photos, videos, or audio files).
- When you have finished traveling the asset or observation, tap Stop streaming.
- Tap Submit once your asset or observation is ready.
Your asset or observation is on the map and its form displays in the panel. If you're working online, others immediately have access to your edits. If you're working offline, your edits are available to others once you sync them.
At your location with a duplicated form
Copy an existing asset or observation's form to a new asset or observation at your location. This is useful when capturing similar assets or observations.
- Open the map of your assets or observations.
- Select the asset or observation you want to copy by doing one of the following:
- Tap the asset or observation on the map to select it manually.
- Do a search for the asset or observation, and choose it from the search results.
- From a pin dropped at its location, go to What's here and choose the asset or observation from the list.
If there is more than one asset or observation at that location, choose the one to update from the list that appears.
The asset or observation is highlighted on the map and its form displays in the panel.
- Tap Copy
.Note:
If the asset or observation is read-only, this copies the form and location.
The asset or observation (or its first point, if it's a length or area) is placed on the map at your location (assuming your GPS accuracy is within the limits you've set), marked by the location target. If the circle of the location target is red, your location accuracy isn't good enough (based on your required accuracy setting), and you must override the accuracy by tapping Add point, manually place the point, or wait for better accuracy. Once placed, the point doesn't move as your GPS location updates.
The type of asset or observation and its form are populated to match those you are copying.
- If you need to update the location, you can do so either using the GPS or manually.
- To manually set the location, move the map so that your desired location is under the location target.
- To use the GPS, tap the GPS button and the location target is centered on your location.
Tap Update point (Update selected point from the Overflow menu
for lengths and areas) and the point moves to the current position of the location target. - If you're capturing a length or area, continue providing the location. You can use your location to add individual points (including offset points), add multiple points based on your location while traveling (streaming), place individual points on the map, or do a combination of the three. Continue adding points until your asset or observation's location is complete.
- Use your location to add individual points—Move to the next place you want to add a point (the location target follows you) and tap Add point. If you are doing GPS averaging, an average is calculated when placing each point. You can capture the location offset from your location.
- Use your location while traveling (streaming)—From the Overflow menu , tap Start streaming. Walk or drive along or around the asset or observation and points are automatically added to the location. The frequency at which they are added depends on the streaming settings.
- Place individual points on the map—Move the map so that the next place you want to add a point is under the location target and tap Add point.
Tip:
You can use the location of an existing point (including one that is part of a length or area). Move the map so that the point with the location you need to use is near the location target such that an orange dot appears over the existing point, and lift your finger from the map. The location target moves (snaps) to the existing point.
- Update the form, including adding any attachments (photos, videos, or audio files).
- Tap Submit once your asset or observation is ready.

Eos Tools Pro opens.
- In Eos Tools Pro, follow the prompts to calculate the offset. Tap Send to pass the location to Collector and return to the asset or observation you are capturing in Collector.
In Collector, the asset or observation is moved to the offset location, or if capturing a length or area, a new point is added at the offset location. The offset metadata is also returned to Collector, and if your layer is configured to record it, it is recorded. Once placed, the point doesn't move as your GPS location updates in Collector.
- If you're capturing a length or area, continue providing the location. You can use your location to add individual points (including offset points), add multiple points based on your location while traveling (streaming), place individual points on the map, or do a combination of the three. Continue adding points until your asset or observation's location is complete.

Use the location of an existing asset or observation on the map as the location for a new asset or observation. The form won't be copied. Perhaps you have assets or observations that share location but are managed separately. This is supported on single places.
Tip:
If you need to use part of the location of an existing asset or observation to define the location of a new (or updated) asset or observation, consider snapping instead of copying the entire location as shown in these steps. To snap, start capturing your asset or observation based on any of the workflows in this topic. While providing its location, use the location of an existing point (including one that is part of a length or area) by moving the map so that the point with the location you need to use is near the location target such that an orange dot appears over the existing point, and lift your finger from the map. The location target moves (snaps) to the existing point. Snapping must be enabled to do this.

Tips
Tips to help you get the most out of your data collection are listed below.
Improve your GPS reception
To improve your GPS reception, make sure you have a clear view of the sky. Avoid tree canopy, and move away from tall buildings. GPS accuracy is displayed in the GPS banner. Tap the GPS banner to get GPS details, including the provider.
Edit location
The location of a single place is a point and the location of a length or an area is defined by a series of points. Locations are edited by adding, updating, and deleting the points.
- A single point is added when you tap Add point. It is placed under the location target. The location target can be positioned over your location by tapping the GPS button or positioned manually by moving the map.
If the GPS button doesn't display, the map is already centered over your location and the location target moves with you. If the GPS meets the required accuracy, the circle of the location target is blue, as is the text in the GPS banner. Otherwise, the circle and text are red. If the location target isn't centered over your location, the GPS button displays, the circle of the location target is gray, and the text in the GPS banner is gray.
Good GPS accuracy 
Inadequate GPS accuracy 
Place a point without GPS If you're placing the point using the GPS and the GPS doesn't meet the required accuracy, you are notified. You can choose to place the point anyway, ignoring the accuracy requirement.
If you are doing GPS averaging, an average is calculated when placing each point using the GPS.
Before the point is added to a length or area, dotted lines show a preview of the location with a point added under the location target.
Dots preview the location - While editing a length or area, the location has a selected point (with a white fill). By default, the last point added is selected. Tap a point to select it.
- Points added to the location of a length or area are added following the selected point.
- Multiple points can be added to a length or area automatically through streaming, following as you move and creating smooth shapes, by tapping Start Streaming in the Overflow menu .
The location target is removed from the map and the blue GPS dot displays. The first streamed point is placed on the map at your current location (assuming your GPS accuracy is within the limits you've set). Walk or drive the asset or observation. As your GPS location updates, points are added to the location. To manually add or update a point, stop streaming, make your updates, and start streaming again.
The frequency at which points are added depends on your settings. If you want the points spaced a minimum distance apart, base the streaming on distance and specify a distance. If you want points added at a minimum time frequency, base the streaming on time and specify a time interval.
- The selected point can be moved by positioning the location target over the new place and tapping Update point (for single places) or Update selected point (in the Overflow menu for lengths and areas).
- The selected point of a length or area can be removed by tapping Delete selected point in the Overflow menu .
- Location edits can be undone by tapping Undo or redone by tapping Redo in the Overflow menu .
Capture locations with altitude
You can directly capture 3D assets and observations to use throughout ArcGIS. If your layer is z-aware, points captured in Collector include z-values (altitude information).
Note:
Capturing assets and observations into a z-aware layer requires a z-value. If you are capturing at your location and your location is being provided through Wi-Fi, a z-value won't be included and you won't be able to add the point.
