GeoKantar vs Lithos

GeoKantar is a surveying app for field work: coordinate transformations, calculations, survey and stakeout, parcel subdivision, PDF plan georeferencing and infrastructure mapping. Everything is in one place and works offline. TOOLS Coordinate Transformation Single-point and batch transformation between more than 50 coordinate systems: Gauss-Krüger (zones 5, 6 and 7), MGI 1901 Balkans, the national grids of Serbia, Croatia, Bosnia and Herzegovina, Slovenia and North Macedonia, WGS84, UTM and US State Plane, with search by EPSG code. Recently used systems stay at the top of the list. Area & Perimeter Enter points manually, walk the boundary with GPS or draw on the map. Area, perimeter and side lengths update instantly, with export to KML, CSV and DXF. COGO Calculator Inverse, polar (radiation), line–line and distance–distance intersection, and area from coordinates. Survey & Stakeout GPS point capture with averaging, manual entry of known coordinates, and stakeout with compass and navigation to the point. Export to CSV and DXF. Localization Helmert calibration to control points, RMS and residuals to check accuracy, and grid/ground scale factor. Parcel Subdivision Import a parcel from DXF, CSV, GeoJSON, KML or SHP and split it by number of parts, area, frontage or road access, or draw the split line yourself. Export the parts to DXF and CSV. PDF Underlay Load a cadastral plan, site plan or design drawing from PDF and georeference it with control points or a known scale. Draw points, lines and polygons with snapping to drawing corners, or detect them automatically from a vector PDF. Export to DXF, CSV, KML, GeoJSON and an image with a world file for AutoCAD, Civil 3D and QGIS. Leveling Enter the starting height and stations; height differences and point elevations are calculated automatically, with export to CSV. DXF to KML/KMZ Convert DXF drawings for viewing in Google Earth, with parcel areas in m², dunams and hectares. Infrastructure Map infrastructure on a satellite map: sewers, water supply, electrical installations and street lighting. Points, lines, photos and a professional DXF export with 13+ layers. BUILT FOR THE FIELD - Works fully offline, data is stored on the device - History from every tool syncs to your account across devices - Guided tour of each tool on first use, plus illustrated help - Dark and light mode - Available in English, Serbian, Croatian, Bosnian, Macedonian and Slovenian GeoKantar is made for surveyors, GIS specialists, technicians and teams who need reliable mobile tools for coordinates, calculations, mapping and project preparation. GeoKantar Pro unlocks advanced tools and premium functionality through monthly or yearly auto-renewable subscriptions.

An iPad & iPhone App for Geoscientists to Collect, Integrate, Analyse, and Interpret Earth Science Data in an Applied GIS Environment. Our Simple & Smart Process An all digital workflow with an intuitive approach away from classic paper challenges and transcription errors and that integrates seamlessly into your existing systems and workflows. Step 1: Collect Any & All Observations Setup your project first, then observe the outcrop, lab results or other relevant geoscientific data, add a point on the field map, verify the positioning and document the needed information with dedicated records. No need to manually transcribe your rained-on, warped, and/or ripped paper field slips, notes, and sketches in the evening. Step 2: Integrate The Stratigraphy Create one or more stratigraphic columns. The individual units are each linked to the rocktype and contact records of the relevant observations so you can easily identify the reference observations of a unit, validate compatibility and make modifications. Step 3: Analyse & Interpret Your Geospatial Data Continuously analyse your collection of observation data, which is automatically categorised onto dedicated location and observation maps and tables upon entry. This will enable you to develop and modify your interpretation, track your progress and plan ahead. Smarter Technologies, Integrated with Care • Harness On-Device GPS To enhance your experience, device capabilities are leveraged for swift data acquisition, comprehensible visualisation and comprehensive analyses. • Compile & Store Spatial Data Each project has GIS at its core for accurate and reliable spatial data work. The data is stored in a SQLite database of the open GeoPackage format. • Access Cloudless, Hi-Res Satellite Imagery Our maps provide the advantage of seamless layers of cloudless, worldwide, high-resolution satellite imagery. • Access 3D Terrain Data Our maps also provide the advantage of 3D map visualisation, detailed terrain with elevation data, and streets, trails and labels. • Access Base Maps Offline Download regions of Mapbox maps to verify and correct your position, even in ‘dark’ spots where acquiring GPS and cellular signals are a challenge. Dedicated Records Document your observations thoroughly without forgetting any details. Each observation contains selectable and open fill forms to complete as part of a dedicated record keeping system with spatial analysis and quality assurance enhancements. Simple. Efficient. Effective. Additional features and tools you need to document your observations and drive accurate Earth systems understanding. • Manage Your Collection Gather like a squirrel nearing winter and view your data on maps, in tables and as stratigraphic columns. • Turn Complexity Into Insights Have your data automatically categorised onto dedicated location and observation maps. • Sketch & Annotate It Make sketches, annotate photos, and write free-form notes with each observation. • Have Confidence In Your Data Provide a confidence rating with each record type and build a robust dataset. ... And Much More Lithos improves over time as new features are added.
