You can choose which of these you record with your data: the values are ignored for any fields you don't add to your feature layer. A high value indicates that your position was influenced by outliers. Standard deviation-An indication of the variation in distance between your final, averaged location and each individual location recorded during averaging.If performing GPS averaging to set a point's location, the default metadata values are recorded along with the following values: If using a single GPS location to set a point's location, the default metadata values are recorded along with the following values: Altitude-Ellipsoidal height received from the GPS receiver (not orthometric height, as used for z-values).Longitude-Position received from the GPS receiver before applying data transformations in the location profile.Latitude-Position received from the GPS receiver before applying data transformations in the location profile.The following GPS metadata values are recorded by Field Maps when using a configured feature layer:

If you use ArcMap or a version of ArcGIS Pro earlier than 2.2, use the Python scripts available on GitHub.If you use ArcGIS Pro 2.2 or later, use the Add GPS Metadata Fields tool after creating your feature class.If you use templates in ArcGIS Online or ArcGIS Enterprise, check the Capture GPS receiver information check box while creating your feature layer.The recommended way to add the fields depends on how you prepare your layers: GPS metadata is cleared if the point's location is provided or updated without using the GPS or while metadata is not available.GPS metadata is populated on point layers only.Keep the following in mind before configuring GPS metadata storage: If using the internal GPS, not all metadata fields are populated. While this topic is focused on high-accuracy receivers, these steps enable recording the metadata from any GPS, including the internal GPS of a device. You should also configure the feature pop-up to hide some of the data from your mobile workers.

If you include GPS metadata fields in your point feature layer, Field Maps can write GPS metadata to the respective fields when editing point features. Storing this metadata can be valuable to assess data quality andĮnsure data collection standards have been met. In addition to geographic coordinates, you can also save other GPS metadata associated with a feature, such as its accuracy and fix type. Configure Field Maps to use the receiver:.Prepare your data to record GPS metadata.You can also improve the accuracy of your position information through differential corrections of the data, supported by some receivers and covered later in this topic.Ĭomplete the following steps to use a high-accuracy receiver with ArcGIS Field Maps: However, in most cases, the more accurate a GPS receiver is, the more expensive it is and the more difficult it is to carry in the field. Today, multiple navigation satellite systems areĪvailable. This is also true for GNSS-the more systems the receiver uses (and the more signals it receives), the more accurate it is.

The more frequencies the GPS receiver uses-and, consequently, the more signals it receives-the more accurate it is. The accuracy of these receivers rangesįrom submeter to centimeter, depending on their ability to Due to the widespread use of the term GPS to refer to both kinds of receivers, the term GPS is used as the generic term in this help documentation.Ī high-accuracy GPS receiver precisely calculates geographic locations using information from GNSS receivers are capable of using various navigation satellite systems, while GPS receivers can only use the navigation satellite system called the Global Positioning System. Global Navigation Satellite System (GNSS) is the standard generic term for navigation satellite systems. For those who perform data collection that requires better accuracy and reliable quality control, using a professional-grade or high-accuracy GPS receiver is usually the best option. The accuracy of these sources varies, and the device's location service is not always reliable.

When collecting location information using a device's location service, position information can be determined from various sources, such as GPS, cellular, Wi-Fi, or Bluetooth networks.

For other projects, such as managing underground pipelines, the location collected must be within a few centimeters of the actual location. For some projects, such as damage assessments, points within 10 feet of the damage may provide enough information. The accuracy required when collecting location data depends on the project you are working on. Postprocess recorded altitudes (z-values).Specify the required accuracy and confidence.Set your receiver as the location provider.
