Note The note that you need to remind when you run the

product

1.3 Prerequisite

Check the following prerequisites before using GeoNURIS WebGIS.

Database - Oracle 10g or higher

Use Oracle 10g or higher version for data storage. In this document, ‘nuris’ of Oracle

account is used.

GIS Engine - GeoNURIS GeoSpatial Server for ORACLE

WebGIS Server - GeoNURIS GeoWebServer

For WebGIS serive, use GeoWeb Server as GeoNURIS data storage which supports

open standard server such as WMS and WFS.

Client - OpenLayers

OpenLayers is open javascript library (it uses no ActiveX). See http://www.

openlayers.org to find out example, method to use it, class references, and users’

forum.

This document is written based on Openlayers library version 2.10.

Sample Document - http://geonuris.ccigis.co.kr/geonuris/data/example.zip

example.html, sample data(cities, continents, ,rivers)

Tools - GeoNURIS Desktop Pro

Install GeoNURIS Spatial Server : See GeoNURIS Spatial Server Installation

Guide


Install GeoNURIS GeoWebServer : See GeoWebServer Installation Guide

In case of which GeoNURIS Spatial Server is not installed, only shape files are possible

to be used



Part

II


2 Introduction

This document explain the series of steps such as

Using GeoNURIS WebGIS Server to load existing shape data into GIS engine

Starting web service using the data loaded.

In addition, in order to improve its performance, this document explains how to use ans

set dynamic cache.

2.1 System Compostion

The composition of Web GIS service using GeoNURIS GeoWeb Server is like below.

Data Area : GSS engine or shape files

GIS Engine : GeoNURIS GeoSpatial Server(GSS) for ORACLE

WebGIS Server : GeoNURIS GeoWeb Server

WebManager : GeoNURIS GeoWebServer Web Manaer

Tools : GeoNURIS Desktop Pro

Client : OpenLayers



Part

III



3 Map Service using GeoNURIS products

This chapter describes how to load downloaded shape files into oracle-based GSS

engine. See Chapter 2.2 for how to service shape file directly without using GSS engine.

3.1 Upload data using GeoNURIS Desktop Pro

1. Run GeoNURIS Desktop Pro and register shape files to Catalog

a. Right click on ‘Catalog’

b. Click on Add Data Store>Add Shape Store


c. <ADD Shape Store> window is popped up.

d. Enter the path of directory where Name and shape files exist.

e. Ex) Name : sample_shape, Directory Path : C:\data

f. Choose added sample_shape and right click.

g. Click on Refresh. The shape lists in the corresponding directory are shown.



2. Register GSS Storage

a. Add GSS Storage to Catalog.


b. Enter connection information.

Host : Host Address where GSS is installed

Port : Port to connect to GSS ( default : 8844)

User : User account of DB

Password : User password of DB

c. Connecting to storage is completed and the lists are loaded. If data do not exist,

nothing is shown.

3. Load data to GSS storage

a. Select all the data lists under sample_shape of ‘Catalog’.

b. Right click to pop up a menu and click on Export. <Export Dialog> is popped up.

c. Choose ‘gss_store’ from Target pull-down menu of <Export Dialog>.

d. Click on [Export] to put shape files into GSS.



e. After completed, choose ‘gss_store’ in Catalog and right click to refresh and check

the data lists uploaded to ‘gss_store’.

Refer: See GeoNURIS Desktop Pro manual for details. GSS Command can be

also used to upload data. GeoNURIS Spatial Server manual for details on this.

3.2 Create GDX for Service

1. Choose Map>New Map from GeoNURIS Desktop Pro menu to create a new project.


2. Choose ‘Catalog’ that services a map and right click to pop up a menu. Click on ‘Add

To Toc’ from the popup menu to add map area.



3. The added layers are added to TOC area and shown in ‘Map Viewer’.

4. Set the style for each layer in TOC area.

Refer: See ‘GeoNURIS Desktop Pro Manual’ for details to set styles. If no specific

settings exists, current arbitrary styles are applied to the map.

3.3 Save Map Settings

1. Click on File>Save from menu to save map settings.

in this document, the file is saved as sampleMap.xml


3.4 Save GDX

1. Register sampleMap.xml created above to GeoNURIS GeoWeb Server.

Copy GDX file, sampleMap.xml, to the gdx folderwhere GeoNURIS GeoWeb Server is

installed.



3.5 Check service using GeoNURIS GeoWeb Server

1. Connect to http://localhost:8880/geonuris and sign in

2. Choose ‘Data Preview’ from the menu on the left to check the lists


3. Click on to check the map

3.6 Javascript Include



Add ./lib/OpenLayers.js to the root folder of OpenLayers folder downloaded to write

service.

<html>

<head>

<title>OpenLayers Example</title>

<script src="http://openlayers.org/api/OpenLayers.js"></script>

</head>

<body>

<div style="w idth:100%; height:100%" id="map"></div>

<body>

</html>

1. Create a map instance.

var map = new OpenLayers.Map('map');

2. Create a layer and call WMS service.

Var baseLayer = new OpenLayers.Layer.WMS('기본맵 ','http://localhost:8880/geonuris/w ms?GDX=sampleMap.xml&',

{ layers: 'ROOT',

transparent: 'false',

bgcolor: '0xffff f f ',

exceptions: 'BLANK',

text_anti: 'true',

anti: 'true',

label: 'HIDE_OVERLAP',

graphic_buffer: '64'}, {

isBaseLayer: true, buffer:0, singleTile: false,opacity: 0.8

}

);

Service URL : 'http://localhost:8880/geonuris/wms?GDX=sampleMap.xml

Check Map Service

Call Example.xml to explorer and check.

http://localhost:8880/geonuris/wms?GDX=sampleMap.xml

4 Dynamic Cache Service to improve performance

4.1 Set Cache

1. Connect to Admin Page ( URL : http://localhost:8880/geonuris)

2. Create cache key

Click on Cache Create from Cache manage in the image below.

4.2 How to Call Service using Cache

Change URL in chapter ‘2.4.3 Create layers and Call WMS service to the value below

http://localhost:8880/geonuris/wms?GDX=sampleMap.xml&Cache_Key=

sampleMap_cachekey

5 Map Service using Dynamic SLD

The style information which is initially set is dynamically applied depending on the

conditions specified by applications.

5.1 Apply Dynamic Style

Initial Screen

Screen after applied



1. How to apply dynamic style

By applying dynamic style, use the URL of the style setting file which you want to

apply when calling WMS.

Ex)http://localhost:8881/geonuris/wms?GDX=sampleMap.xml&SLD=http%3A%2F%

2Flocalhost%3A8881%2Fgeonuris%2Fcontinents.xml&',


2. How to call OpenLayer

userLayer = new OpenLayers.Layer.WMS(

'sld change', 'http://localhost:8881/geonuris/w ms?GDX=sampleMap.xml&SLD=http%3A%2F%2Flocalhost%3A8881%2Fgeonuris%2Fcontinents.xml&',

{

layers: 'NURIS.CITIES,NURIS.RIVERS,NURIS.CONTINENTS',

transparent: 'true',

bgcolor: '0xffff f f ',

exceptions: 'BLANK',

label: 'HIDE_OVERLAP',

graphic_buffer: '64'

}, {

isBaseLayer: false, buffer:1, singleTile: false,

opacity: 0.7

}

);

Call URL

When calling URL, add SLD parameters.

Write the targeted layer lists in the part of 'Layers' parameter.
