What is GeoServer?

  • For sharing analyzing and editing spatial data
  • Serves map (WMS) and feature (WFS) for sharing, analyzing, and editing geospatial data from spatial data sources using open standards
  • Multiple output formats (Esri Shapefiles, KML, GML, GeoJSON, PNG, JPEG, TIFF, SVG, PDF, GeoRSS)

GeoServer

  • Relational Database Management System
  • Reduces spatial data to tables
    • With a geometry column 
  • Integrates easily with QGIS

Relationship with PostGIS

PostGIS is an open source database based on PostgreSQL

add PostGIS to GeoServer

PostGIS can analyze data, store data, and manage data.

GeoServer simply stores data.

QGIS Plugins

To install GeoServer

Download at BoundlessGeo

Register and they will send you an email to a link where you can then download OpenGeoSuite

You will need about 1 Gig of free space

You will install PostGIS, OpenLayers, GeoWebCache, along with GeoServer

 

Resources

  • Boundless Online
  • Boundless localhost:8080
  • GeoServer.org

Read about GeoServer and follow directions provided by Boundless 

There are lots of details in the README from the downloaded bundle from Boundless

To install on your machine...

choose the download package for your OS

Read through Quick Start Guide provided by GeoServer

Mistakes that I made

  • Lost admin password
  • Uninstalled and re installed GeoServer

VIP information (questions posed in homework)

Key Terms

See Homework Handout - answers to the questions posed in the HW can be found by reading content from the links provided above.

User Modifiable Content

The directories that do contain user-modifiable content are: 
logs, 
palettes, 
templates, 
user-projection, 
www.

Several ways to

view and edit data on GeoServer

  • GeoServer - previewer
  • GeoExplorer - Web-based viewer for editing layers
  • QGIS 
  • pgAdmin - query, edit and organize your data in tabular format

Several ways to

load data to GeoServer

  • Directly with the directory 
    • Command Line
  • GeoServer Layer Importer
    • Accessed through Layer Importer REST API
    • Or GeoServer Web interface
  • QGIS + Suite QGIS Plugin
  • pgShapeLoader
    • Graphical tool to import and manage db and files in PostGIS

We are going to...

Install and get to know GeoServer

  1. View vector data
  2. Add vector data
  3. Create New Layer Group

...using GeoServer

Open OpenGeoSuite

Know that PostgreSQL runs on ports 8080 and 5432

Leave them as default

unless you know of any conflicts already

For directions on how to change the port see the README.pdf that came with install

This is what the dashboard will look like

From the dashboard

Under GeoServer

Click Get Started-->

Read through the directions and be sure to

  • Change the log in information
    • Default log in found in ReadMe file
  • Change contact info

before we load data know that

Defining Projection

is imperative 

Spatial Reference System 

SRS

Native SRS — Refers to the projection the layer is stored in. Clicking the projection link displays a description of the SRS.

Declared SRS — Refers to what GeoServer gives to clients

SRS Handling: — Determines how GeoServer should handle projection when the two SRS differ

1. View Data

Before we load data we need to learn about how it can be used.

Read through this information about what is required to load layers into GeoServer and how to make them editable

  • Adding name and metadata
  • Bounding box
  • and more...

View the Demo

2. Add Data

  • First you need to create:
    • Create a New Workspace
      • What services will you offer?
    • Create New Store

2. Add a Data

After you have created a new data store and a new workspace, you are now ready to upload a .shp file

  • From Geoserver -->Click Layers-->Import Data
  • Select data source--> Spatial Files
    • Navigate to the a directory and .shp file
    • Select the newly created workspace and data store
  • Click Next

2. Add a Data

You may have to modify the layer

  • Add keywords associated with the data
  • Set Coordinate Reference System
    • You may have to look up the UTM code
      • example: Bo 
    • You may have to set the bounding boxes - your choice on how to set it
  • Click Next

2. Backup plan

If you couldn't get your data to upload

You may use this example and data provided in this example

http://docs.geoserver.org/stable/en/user/gettingstarted/shapefile-quickstart/index.html

3. Create Layer Group
