Esri File Geodatabase
Open BetaFileGDB는 복잡한 지오데이터를 저장하기 위한 Esri의 형식입니다. 다중 레이어, 토폴로지, 도메인, 서브타입을 지원합니다. 엔터프라이즈 GIS의 사실상 표준입니다.

FileGDB 형식 소개
File Geodatabase is the native storage of ArcGIS. It is not a single file but a .gdb folder holding tables, indexes and service records. Esri made it the replacement for the shapefile, and in corporate GIS it has remained the main unit of storage: long field names, many layers side by side, domains and subtypes, and no two-gigabyte limit per table.
Export to FileGDB is chosen when the data goes to an organization running on ArcGIS Pro: a municipality, a design institute, a utility company. There a geodatabase is the familiar exchange unit, and sending one is usually faster than explaining how to open a GeoJSON.
Each map layer becomes a separate feature class inside a single geodatabase, with OpenStreetMap attributes and a spatial index. Coordinates are WGS84 (EPSG:4326). Since a .gdb is a folder, it is downloaded as a ZIP archive: unpack it and you will find a directory with the .gdb extension inside.
Writing is done by the open GDAL OpenFileGDB driver, so no Esri libraries are needed for the export. Domains, subtypes and topology are not carried over — those add-ons simply do not exist in OpenStreetMap data.

FileGDB 내보내기 방법
내보낸 뒤 여는 방법
- Unpack the archive first — ArcGIS and QGIS work with the .gdb folder, not with a ZIP file.
- ArcGIS Pro — in Catalog press Add Database or Connect, point it at the .gdb folder, then drag the feature classes you need onto the map.
- QGIS (free) — Layer → Add Vector Layer, source type "Directory", driver OpenFileGDB, point it at the .gdb folder; the layers will appear as a list.
- ogr2ogr — ogr2ogr -f GPKG out.gpkg map.gdb converts the geodatabase into GeoPackage, PostGIS or Shapefile in one command; ogrinfo will show the list of feature classes.
- FME, Global Mapper, MapInfo — read FileGDB with their standard readers; send the client the whole archive, not individual files from the folder.
