Could you build this?
Partial While the mobile UI and standard mapping are manageable, accurate 4-DOF or 6-DOF G1/G7 exterior ballistics differential equation solvers and GIS-heavy offline public land parcel caching require specialized domain engineering.
What it would actually take: Building a reliable ballistics and mapping app requires a cross-platform mobile stack (Flutter/React Native or native Kotlin) integrating GIS libraries for rendering large offline vector tile layers (BLM/USFS parcel datasets). The core hard component is an accurate numerical integration engine (Runge-Kutta 4th order) implementing standard exterior ballistics point-mass models with G1/G7 drag functions and atmospheric condition adjustments (density altitude, Coriolis effect). This requires domain expertise in applied physics/aerodynamics and high-performance offline geospatial data handling.
