Where do field boundaries come from?+−
From several sources, each with its own accuracy. The most accurate is a GPS receiver survey along the field edge; the fastest is digitising from a satellite image; cadastral plots show the boundaries on paper, and machinery tracks show the actual edge of cultivation. askcust brings them onto one map, and the agronomist approves the working boundary for each field, keeping the others for reference.
Why does the same field have different areas in different software?+−
Most often because of different boundaries: a survey, the cadastre and digitising give different edges. The second reason is the calculation method: an area computed directly in web map coordinates (Web Mercator) is inflated 2 to 2.7 times at Ukraine's latitudes. The askcust map calculates area on the WGS 84 ellipsoid and shows which boundary each area comes from, so a discrepancy can be explained rather than guessed.
Can cadastral plots be overlaid on the field map?+−
Yes, cadastral plots are a separate layer above the field boundaries. They are loaded from the XML exchange files of land survey documentation, and their coordinates are converted from the national USK-2000 system into the map's system. The layer shows which plots a field consists of and where the field goes beyond the documents. Contracts and rights holders are added to plots by the land bank module.
Does the map work on a phone in the field?+−
Yes. The mobile version downloads boundaries, the needed layers and the basemap for selected fields in advance, so the map, the current location and field edges are available without a mobile signal. Notes, photos and geotagged scouting points are stored on the phone and synchronise when a connection returns. The cache size is set to the farm's area and the devices' memory.
Can boundaries be exported to a machinery terminal?+−
Yes. Field boundaries are exported to ISOXML for ISOBUS terminals and to Shapefile, which most other terminals and precision farming programs accept. File requirements differ between manufacturers (structure, coordinate system, field names), so askcust tests the export on a sample file and on the farm's real terminal, not just against the specification.
How much does a digital field map cost?+−
The cost depends on the number of boundary sources, layers, export formats and integrations with other systems, not on the farm's area. The first stage (agreed boundaries and areas, crop history and export) is estimated by askcust with a fixed scope after the existing boundaries are collected; layers and exchange with accounting and telematics are added in later steps.
