CSV and geospatial file conversion

These tools only assist with geographic data processing. Outputs are for technical reference and must not be used for survey acceptance, construction, or official cadastral demarcation. For critical work, rely on professional GIS software and licensed survey products. All computation runs locally in the browser; files are not uploaded. This site does not operate a public map tile service, does not provide a geography API, does not parse classified coordinates, and does not display militarily sensitive locations. The basemap is OpenStreetMap.
