JMap Photo reader

Read	Yes
Write	No

JMap Server can read photo files (360 or normal) in JPEG format as a source of spatial data. These photos can be viewed in JMap Pro and JMap NG applications from point layers associated with this type of data source.

JMap Server reads all image files in the specified directory. Files that are not images or image files without spatial information (latitude and longitude) are ignored.

From each file, JMap Server reads the metadata (latitude, longitude and other information) and writes them to a JMap Spatial table. Coordinates (latitude and longitude) define a point and other metadata are attributes of the point. Direction data can be used, for example, to apply a rotation to symbols that represent the points. 360 photos are processed as normal photos.

Parameters
Selected folders	Select one or more folders that contain the photos in JPEG format. You can structure the photos into different independent folders to create multiple spatial data sources (e.g. Photos 2020, Photos 2021, etc.).
Reader options	Check the Include subfolders option so that JMap Server read the files stored in the subfolders. Select field labels for geographic coordinates, altitude, and direction.
Attributes	Check the attributes to include in the spatial data source. Select the key attribute corresponding to the unique identifier.
External attributs	You can add external attributes by selecting fields or by using an SQL query. The External Attributes section provides details on adding external attributes.
Projection	Select the original projection of the photos. The photo coordinates are expressed in latitude and longitude, so the projection is Longitude/Latitude (WGS 84) - EPSG: 4326.
