To support spatial planning needs, Archizem specialists produced a digital topographic base at a scale of 1:10,000 for a settlement territorial community in Volyn Oblast. The work was performed under the USAID Governance and Local Accountability (HOVERLA) Activity, commissioned by DAI Global, LLC (DAI).
Due to airspace restrictions in Ukraine preventing aerial photography, the base was compiled using up-to-date satellite imagery with a 40 cm/pixel resolution. To ensure proper geodetic control, the team inspected available points of the State Geodetic Network.
The office processing phase included feature and terrain vectorization, topological consistency checks, attribute population, and merging of vector layers into a seamless dataset. Following office interpretation, field verification was carried out, supplemented by total-station surveying of objects identified on site using GNSS technologies. Final deliverables were prepared in ArcGIS in compliance with applicable topographic classification requirements for the given map scale.
