The words Dipper Field uses, from record type and asset to RTK fixed, mount point and State Plane, and what each one means in the app.
Updated October 2026
Terms are grouped by topic. Words in bold are what you see on screen.
Projects and records
Term
What it means
Project
Everything for one job: its record types, records, photos and reference layers. It's stored on this device, inside Dipper Field.
Record type
A kind of thing the project records, such as hydrants, trails or parcels. Each one has a shape, points, lines or areas, and its own fields.
Record
One thing you recorded: its location or shape, its answers, and its photos and other media.
Field
One question a record answers. Each field has an answer type, such as text, a number, a choice, a date or a signature. See answer types.
Point, line, area
The three shapes a record type can have. An area can have holes and more than one part. See points, lines and areas.
Vertex
One of the points that make up a line or an area.
Draft
A record you started and didn't save. It's kept on this device so you can finish it later.
Template
A project's setup without its data: record types, fields and collection rules. Dipper Field comes with ready-made ones, and you can save and share your own as .fwt files. See use and share templates.
Your name
The name you can enter in Settings. It's saved with the records you collect or change, so a shared project shows who did the work.
Deleted records
Records deleted from a project. They stay in the project, under Deleted records on the Project tab, and Restore brings one back.
Assets and inspections
Term
What it means
Asset
A record you keep and come back to, such as a hydrant, a sign or a manhole. A record type holds assets when Keep and revisit these is on.
Inspection
A visit to an asset. Each inspection has its own fields and a result: Normal, Problem found, Skipped or Unable to inspect. See set up inspections and intervals.
Inspection interval
How often each asset should be inspected, in days, set in Inspection frequency. Inspect as needed never makes an asset due.
Due for inspection
An asset whose interval has run out since its last Normal or Problem found result. See see what's due or overdue.
Overdue
In a Compliance summary report, an asset that is past its date with no inspection recorded.
Inspection round
A list of up to 500 assets to inspect one after another. You can stop and pick up where you left off. See run an inspection round.
Problem
Something wrong found during an inspection. It has its own Problem level from 1 to 5, description, position and photos, and stays open until a recheck closes it.
Recheck
A later inspection of one problem. Normal closes it; Problem found keeps it open. See record problems and rechecks.
Finish-work summary
Counts of the records, inspections, problems and photos from today or from the latest round. See end-of-day summary.
Maps
Term
What it means
Map background
The map drawn under your records: a Google map, a map service you added, or a map saved or imported for offline use. You choose it in Map layers. See choose a background map.
Map service
An online map you add yourself from its address: an XYZ, WMS, WMTS or ArcGIS tile service. It's listed under My maps. See add your own map service.
Saved for offline use
Areas of a map saved to the device, and map files you imported. They draw without a connection, for every project on the device.
Reference layer
A file you already have, such as parcels or pipes, shown under your records to work against. It can't be changed and isn't counted as records. See reference layers.
Snapping
Placing a point exactly on the corner or edge of something nearby. Snap to nearby records in Settings snaps to records; Snap to this layer snaps to a reference layer.
Offset point
A point you can't stand on, placed by its distance and direction from where you are.
On-site info
The date, time, address, coordinates and weather printed on a photo taken with Dipper Field's camera.
GPS and receivers
Term
What it means
Location source
Where positions come from: the phone's own GPS or a receiver. It's in Settings.
Receiver
An external GNSS receiver that sends positions to Dipper Field. iPhone and iPad connect over Bluetooth LE or Wi-Fi; Android also over Bluetooth Classic and USB. See which receivers work.
Estimated position error
How far off a position may be, as the phone or receiver estimates it. The actual error may be larger. See read the accuracy display.
Location accuracy
The accuracy a record type asks for. A worse position shows a warning, or can't be saved when Don't allow saving if worse is on.
RTK
Real-time kinematic positioning. A receiver uses corrections from a base station or network to measure far more precisely than on its own.
RTK float
Corrections are arriving, but the solution isn't resolved yet. Typically within a few inches to a foot or so.
RTK fixed
RTK is resolved. Typically within an inch. Record only with RTK fixed holds recording until the receiver is fixed. See record only with RTK fixed.
Averaging
While the receiver is RTK fixed, Dipper Field averages several fixed readings into each point. It happens by itself.
Antenna height
The height from the ground to the receiver's antenna, such as the length of its pole. It's taken off the heights a record keeps, so they're the height of the ground.
NTRIP
The way RTK corrections are sent over the internet. Dipper Field fetches them from an NTRIP caster and passes them to your receiver. See get RTK corrections with NTRIP.
Caster
The server that sends the corrections, set by its Caster address and Port.
Mount point
One stream of corrections on a caster. Your provider says which one to use, or you can choose one from the caster's list.
Coordinates and heights
Term
What it means
Coordinate system
How numbers describe a place on the earth: longitude and latitude, or a grid of eastings and northings in feet or meters. See coordinate systems for import and export.
Longitude and latitude (WGS 84)
Degrees east and north, EPSG:4326. Always at the top of the coordinate system list. GeoJSON, KML and GPX files always use it.
Projected coordinate system
A flat grid in feet or meters, such as UTM or State Plane. Survey point files and CAD drawings need one.
EPSG code
The number that names a coordinate system, such as 6420. You can search for a system by its code.
State Plane
The US states' own coordinate systems, one or more zones per state. Each zone comes in US survey feet (ftUS), international feet (ft) or meters.
UTM
A worldwide grid of 60 zones, in meters.
NAD83(2011)
The current realization of the North American Datum, used for State Plane and UTM zones in the United States.
Elevation
Height above sea level, by the geoid model the receiver or phone carries.
Ellipsoidal height
Height above the ellipsoid, a smooth mathematical shape of the earth, as a receiver measures it.
NAVD88, GEOID18
NAVD88 is the US height system for survey and engineering. GEOID18 is NOAA's model for working it out from GNSS heights. See heights: NAVD88 and GEOID18.
Files and sharing
Term
What it means
Data Files
Where Dipper Field keeps files on this device, and the connected locations you browse. See the Data Files screen.
Connected location
A cloud drive or storage you connect in Data Files: Google Drive, OneDrive, Dropbox, S3-compatible storage or a network folder. Up to 3 at a time. See connect cloud storage.
Transfers
Uploads and downloads between this device and connected locations, with their progress. They keep going when you leave Data Files.
