User Manual for using ArcMap application

При купување на производи од категорија WMS сервиси, на корисникот му се

доставува линк за пристап до соодветниот сервис, кој може да дозволува пристап

до еден или пак повеќе слоеви со можност за вклучување и исклучување по

потреба од страна на корисникот. Линкот е наменет за отворање во GIS софтвер,

како што се ArcMap, QGIS и други.

Постапката за преглед (отворање) на геореференцаната слика која се доставува

како продукт е слична во секој GIS софтвер, сепак во продолжение следи опис на

истата во ArcMap и QGIS, како најчесто користени.

1. Opening WMS services using ArcMap

ArcMap is a graphical user interface application in which there are incorporated

advanced tools for manipulation of shape files and geo – database with an intuitive

interface of the ArcGIS file management application, called ArcCatalog with some of

the functionality of ArcInfo that includes capabilities for data manipulation, editing, and

analysis.

ArcGIS is Esri's geographic information system (GIS) for working with maps and

geographic information. It is used for: creating and using maps; compiling geographic

data; analyzing mapped information; sharing and discovering geographic information;

using maps and geographic information in a range of applications; and managing

geographic information in a database. The system provides an infrastructure for making

maps and geographic information available throughout an organization, across a

community, and openly on the Web.

The user adds new WMS (Web Mapping Service) by right click on the WMS button from

the right side menu (catalog), as shown on Figure 1.1. The WMS connection form

opens (Figure 1.2) and the user enters the URL received by buying the service, the

username and password in order to load the service (Figure 1.3). Then he can see the

service (the name of the layer) listed below the created WMS service with the provided

URL (Figure1. 4).

The user can see the wms by drag and drop of the name of layer from the right catalog

list to the map area (Figure 1.5). The layer will be displayed on the left side layers tree

with a checkbox beside the name. The checkbox will be marked as the layer is

displayed on the map. The user may add as many layers on the map as there are

provided / bought from the url of the wms services and then to add or remove them from

the map by marking and deselecting the checkbox beside the layer name accordingly.

For each point of the map, the feature info is available by clicking on the info i button,

and then clicking on the map, which will open a table with feature info for all layers

displayed on the clicked point (Figure 1.6).

2. Opening WMS services using QGIS

QGIS (Quantum GIS) is an application that enables users to create maps with multiple

layers in different projections. This application supports creating and opening raster

layers which consist of set of images and vector layers which are defined by vector data

per feature, which can be point, line or a polygon.

QGIS supports raster images in various image formats (in the case of our application

the images are in png format) as well as geo-referencing of raster images, which means

placing the images on proper location on the map, according to the selected geodetic

reference system.

The user adds new connection for WMS (Web Mapping Service) by right click on the

WMS button from the left side menu. The user selects New Connection and new

window opens for defining new connection for accessing WMS services from it.

Figure 2.1 – Adding WMS connection

Figure 2.2 – Creating WMS connection

The user fills in the Name field with the name he wants to use for the connection, enters

the link got when buying the service in the URL field. The User name is required and the

user enters his username used for logging into the OSSP WEB GIS application when

buying the service. The password field is not required, as the user will be prompted for

the password when he will want to open the service from the connection regardless.

Figure 2. 3 – Filling in the form for creating WMS connection

By clicking the OK button, the new WMS connection is created and it will show in the

WMS connections list (in this case consisting of KIS, rasters, sde, testsde, UCAD) and

the user can see the bought services from each by clicking the plus (+) sign.

Figure 2. 4 – Connections for accessing WMS services

The user accesses the service by right click on the mouse on the proper name from the

list of bought services (e.g. ADMINISTRATIVNI_GRANICI shown on Figure 2.5,

NASELENI_MESTA, shown on Figure 2.6) and then selecting Add Layer option to add

the layer on the map.

Figure 2.5 – Service ADMINISTRATIVNI_GRANICI (Administrative Borders)

Figure 2.6 – Service NASELENI_MESTA (Borders of habitat units)

Optionally, the user may select more layers from the list of WMS services and then to

click on the Add selected layers option, which will add all selected layers from the list on

the map at once, so he user may see them all together, as shown on Figure 2.7 and

Figure 2.8 below.

(Borders of Local Government Units, Borders of Habitat Units and Municipalities’

Borders)

Figure 2.8 - Service topokarta_25000_raster, SMALLIN SMALLPNT

After the layer is added on the map, the user can select the option to see the feature

info (shown on Figure 2.9) and then by clicking a point on the map a table with Feature

Info for a selected layer from those displayed on the map opens (e.g. for the service

NASELENI_MESTA is shown on Figure 2.10), or for all the layers displayed on the map

(e.g. on Figure 2.11 for the layers NASELENI_MESTA, ADMINISTRATIVNI_GRANICI

and SCDP_GR, and on Figure 2.12 for the layets NASELENI_MESTA,

ADMINISTRATIVNI_GRANICI and LANDCOVER).

To remove a layer from the map, the user selects the layer he wishes to remove from

the left side list of WMS services, and then from the Layer tab on the main menu selects

the option Remove Layer/group. In case the user wants to remove all the layers from

the map, selects the option Hide all layers, and can see them back on the map by

selecting Show all layers from the Layers tab on the main menu. If the user wants to

see only some of the layers on the list, selects them and them selects the option Show

selected layers from the Layers tab.
