Future Thota Tools
Free to use and try out — browser tools to streamline the drone mapping workflow on field, and move from raw photogrammetry outputs like Ortho, DTM, and DSM to analytical, client-ready deliverables, all in one place.
Built from real fieldwork and used in-house for our own mapping services, kept lean by design — connected tools, not scattered software islands, customisable to fit your workflow.
Available now
Drone tools
More ports from our internal drone-processing toolkit, on the way.
Drone Media Map
Turn geotagged drone video and photo captures into an interactive site map, with toggleable layers per flight.
Terrain 3D Viewer
Explore elevation data from a site survey as an interactive 3D terrain model, right in the browser.
GIS processing tools
Boundary, contour, and mission-file conversion utilities, on the way.
Area Calculator
Slope-corrected true surface area from a clipped elevation raster — accounts for terrain that a flat map projection understates.
Raster Clipper
Clip elevation or imagery rasters down to one or more boundary polygons.
Contour Generator
Generate elevation contour lines from a DTM, exported as layered DXF for CAD and GeoJSON for mapping.
Contour to DXF
Convert an existing contour GeoJSON into a CAD-ready DXF, one layer per elevation, with 3D values preserved.
GeoJSON to KMZ
Convert an edited waypoint-path GeoJSON into a flight-controller-ready KMZ mission file.
KML to GeoJSON
Convert a flight-controller waypoint mission file into editable GeoJSON for touch-ups in a GIS editor.
QGIS GeoJSON to KML
Convert a GIS-edited boundary into a KML file ready for area-mapping mission planning.
Sunlight Exposure Tool
Simulate sun exposure across a site through the day using elevation data — useful for siting crops or infrastructure.
FAQ
What GPS data can I use as input?
A walked track exported from a GPS watch or phone mapping app (as GeoJSON), or a boundary/mission file from an RTK GPS tool or drone remote controller (KMZ). In Field turns either into an editable boundary and a flight-ready mission — no manual format conversion needed.
Does In Field work with my drone?
Yes — In Field is tested against real enterprise mapping and waypoint drones, and the exported mission follows a standard flight-controller format, so it isn't limited to one platform.
Can I use it for GIS work that isn't drone mapping?
Yes — the boundary and line editor works as a standalone polygon/line tool. Draw or edit a shape, then export it as GeoJSON or KML for use in QGIS or any other GIS software.
Do I need to install QGIS?
No — boundary and flight-path editing both happen in the browser. QGIS (or another GIS tool) is still useful for further processing after exporting a GeoJSON or KML boundary, but it's optional, not required.
Is it free to use?
Yes, In Field is free — we just ask for an email address before you start, mainly so we can reach you about an issue with an export.
