Why geoserver
- 1. GeoServer FOR GEOSPATIAL DATA MANAGEMENT
- 2. Loading vector/raster data to mapping library directly
- 3. Statement of need: GeoServer Big File (1GB). How to load in leaflet/openlayer? Various format of data (.shp, .tiff, .gpkg etc). How to produce web- maps from these datasets? Data from services (WMS, WFS, WCS etc). How to manage them? How to manage large number of datasets and how to store them in a meaningful way? How to mange style for each layers? How to produce the OGC standard services?
- 5. Introduction An open-source server written in Java that allows users to share, process and edit geospatial data. Can publishes data from any major spatial data source using open standards Can easily connect to the web-based maps such as Leaflet/Openlayer/MapBox Provides the OGC standard outputs WMS, WFS, WCS
- 6. ArcGrid Services: (WMS, WFS, WCS etc) Image mosaic WMS WFS WCS WPS GeoServer I/O
- 7. Web Map Service (WMS) It provides the map as a image (eg, PNG, JPG etc) Standard protocol developed by OGC Makes easy to share geospatial data as a map Easy to visualize, query and get the info about map Available for vector as well as raster dataset. getfeatureinfo
- 8. Web Feature Service (WFS) WFS service returns features with geometry and attributes that clients can use in geospatial analysis One can think WFS as a GeoJSON API. But it can provide the output as Shapefile, CSV, GML2, GML3 as well Only available for vector data
- 9. Web Coverage Service (WCS) Web-based retrieval of coverages One can think of WCS as the equivalent of Web Feature Service (WFS), but for raster data instead of vector data WCS is able to return more information, including valuable metadata and more formats
- 10. Web Processing Service (WPS) OGC service for the publishing of geospatial processes, algorithms, and calculations WPS acts as a full remote geospatial analysis tool, capable of reading and writing data from and to the server WPS is not a part of GeoServer by default, but is available as an extension
- 11. Data management Structure Workspace Datastore Layer Layer Raster Vector Service Layer Group • Workspace • It is the top-level directory for storing similar kind of data • Datastore • Physical location of data • It can be vector, raster and service source • Layer • Individual map • Layer group • Collection of layers
- 12. Workspace
- 13. Datastore
- 14. Layers • Each dataset is the layer of content • Gather into layer group to arrange the layer into basemap • Layer can be previewed in openlayer
