Can sometimes be directly imported, but will often need to be translated to a native tabular format for the software being used (e.g. Plaintext, often delimited with tabs, commas, pipes, or semi-colons. Can be directly read into some programs (e.g., ArcGIS) but is sometimes buggy. Can sometimes be directly improted (e.g., QGIS, ArcGIS). Plaintext tabular data delimited by comma. Is often associated with a shapefile (see above), but is sometimes standalone tabular data which can be opened in older versions of Excel or Access. The equivalent of a grid attribute table, for integer grids only. The extent/boundary metadata for the grid Non-georeferenced lossless compressed image data which, when associated in a directory with a pgw (“world file”) of the same file basename, is a GeoJPEG, georeferenced image. Lossy compressed image data which, when associated in a directory with a jpw (“world file”) of the same file basename, is a GeoJPEG, georeferenced image. tfw for info).jpx can contain additional metadata. Sometimes includes an associated jpw (“world file”) of the same basename (see. Uncompressed image data which, when associated in a directory with a tfw (“world file”) of the same file basename, is a GeoTIFF, georeferenced image.Ĭompressed image data often georeferenced. sbx, etc., which are often used for indexes or some other metadata Shapefiles can also include many other file formats such as. It’s a plaintext file that can be read on its own. (Optional) Stores spatial reference and projection metadata. It’s actually a tabular format called dBASE, which can be read on its own, in other programs. Shapefile data file which stores attribute data. Sometimes somewhat confusingly refered to a as a shapefile. When viewed in an ArcGIS filesystem dialog, is usually displayed as a single file. Is actually a collection of files, not a single file, all in the same directory, with the same file base name (the name without the extension). Here is the entire script for making GeoJSON for UK countries. ukcountrysim <- mssimplify(ukcountryjson) Save as GeoJSON file on the file system.
Has traditionally been the “standard” vector format for ArcGIS. The rest is straightfoward, we can just convert it to GeoJSON inside R, simplify the polygons to reduce the output data size, then save it to a file system. Spatialite is an an extenion to sqlite which spatialally enables it. The File Geodatase is a directory, which contains many files which can not be read on their ownĮxtension is optional for this format, but is often. XML-based GPS data file, usually coming from a GPS device.Įsri File Geodatabase can be used to store vector and raster data as well as more complex data containing topologies, and other supporting files. You can uncomrpess this with 7zip (free/open) and you will see plaintext KML Is a XML-based plaintext file that may contain geometry, data, or a pointer to a web service
