2 Concept The concept of this module is to understand how to create basic content for an ArcGIS Server, while there are many concepts that will be in a more advanced format; this lesson will involve the creation of services and web maps as the two central focuses. An ArcGIS Server will create services that can be consumed by other applications, including ArcGIS Desktop, ArcExplorer, Web Maps, Google Earth, Flex Server, Silverlight, Google Maps and HTML 5. In this lesson we will concentrate on the creation of the services and creation of web maps. The use of geodatabase and SQL databases will be explored and the difference noted most importantly that a SQL database will provide the ability to edit on a web browser. Prerequisites It is assumed that the participants in this lesson will be experienced with the use of ArcGIS Desktop and can create basic maps and have used a geodatabase. It is also assumed that the participant will have used ArcCatalog. ArcGIS 10 will be utilized for this exercise, but an experienced user of Arc 9.x should have a very short learning curve for these activities. It is assumed in this workshop that all components will be installed prior to beginning this lesson and configured properly; this includes the Microsoft Server 2008, IIS, Microsoft SQL Express, ArcGIS Server 10, ArcSDE, and ArcGIS Desktop. The server will be configured running Microsoft Server 2008 and the participants will connect to the server through a virtual desktop connection. The server can be a physical or virtual box that allows for remote access. Data Data used in this lesson can be obtained at or from other data source of your choice. The JCTC data library is composed by geography, based on countries, states, counties and type of shapefiles. All data obtained from the data library will need to be downloaded, decompressed and stored on the server. Services will be utilized from other online source as base layers. Introduction to ArcGIS Server Page 2

3 Process The process to connect to the server will be through the use virtual desktop application. In general connections to servers are done through a remote desktop which is a windows program that gives you the ability to connect securely to other computers. This is the traditional way you work with a server, rarely are you at the actually server but instead are generally connecting remotely. To use remote desktop you need to be an authorized user of the server that you are connecting with. In general you are required to give the server name (or IP Address) and your authorized credentials to connect (if using Active Directory it would be your standard login). Once you have connected to the server you will be able to work with it just as if you are working on your desktop. You must be aware that this is a server class machine and not a desktop and thus the look and feel is slightly different. Creating a Service Down Loading Shapefiles First we want to launch ArcGIS Desktop version 10, ArcCatalog and Internet Explorer. Browse to the Techcenter GIS Data library ( ) or other data sites and select a state map with counties, US map with state boundaries, and zip codes of a state. Download the data and decompress it in a folder on the server. Next we will add this data into a geodatabase. Creating a File Geodatabase In ArcCatalog create a new file Geodatabase and give it an appropriate name and import the shapefiles into the geodatabase. Creating a Project Open ArcGIS Desktop and add data from the geodatabase, i.e. the layers that were added to the geodatabase Figure 1: Basemap via ArcCatalog. Your geodatabase needs to be located on the ArcGIS Server or an appropriate shared folder needs to be made. Using the symbology function appropriately code the layers, both with the boundary color and a hollow fill and order the layers in the table of contents. In addition turn on labels for a specific shapefile and set the zoom level so that the label turns on and off as the user zoom. All these features will be utilized by the ArcGIS Server. Save the mxd file in an appropriate location on the server, such as the arcgisinput folder. This should be in the ArcGIS Server folder. While a service can be produced within ArcMap we will create the service from the Service Manager of the ArcGIS Server. Introduction to ArcGIS Server Page 3

4 Creating a Service in Service Manager The Service Manager is in the ArcGIS folder and is a web page which is available only when connected to the server. Appropriate credentials are required to connect to the Service Manager. Note the login must include the domain and the username as well as the password. If the user is using AD and the server is connected within the domain then their active directory account should be used for connecting. Once the login is Figure 2: ArcGIS Server Login completed a window should open like Figure 3: ArcGIS Server Manager. From this window you can create services and web pages; at this point we are only going to focus on the services. In a later point in this exercise we will develop a web application upon the ArcGIS Server. A Service is an operation which can be used on the ArcGIS Server as well as in other applications such as Google Maps, ArcGIS Desktop, Flex and Silverlight. Introduction to ArcGIS Server Page 4

5 First Click on Services and select Publish GIS Resource. When you start this application you should have no services already created (there will be example services for this workshop, but on a new install the area will be empty). Note you can start and stop services; when a service is stopped it is not available and visible to those connecting Figure 3: ArcGIS Server Manager to the server. When you select Publish GIS Resources you will start a wizard that will walk you through all the required steps. Once a service is created you can edit the service at this location by double clicking on the service name. Remember you can also create a service in ArcGIS Desktop which will be discussed within this module. Figure 4: Services Introduction to ArcGIS Server Page 5

6 First you will need to select a Resource that will be used to create the service, i.e. a MXD file, (Note: you can also use an MSD file but only if not creating a feature service with a relational database), you can browse to the location of the resource. Next you need to select the name for the service that will be created; this name will be visible to the public so care should be taken in Figure 5: GIS Resources the selection of a descriptive name. Finally a location to save the service must be provided, I generally use the default location. Figure 6: GIS Resource will have a versioning problem. Next the type of service must be selected; the first check box is always checked and cannot be unchecked. I generally always create a KML service that can be used on a Google Map or Google Earth. If you have a specific operation that will utilize other service types then check all that are appropriate, do not just check all services automatically as this will cause a slowing in the performance of your service. A Feature Access can only be created if you are using a relational database, a file database is not a relational database. If you want to edit the feature class you must on the Pooling select Not Pooled if this is not done you Introduction to ArcGIS Server Page 6

7 This window in Figure 7: Services Location shows the different services which you created and their saved locations, which is important to note so that they can located for future mapping projects. Click Finish to end the wizard. Figure 7: Services Location Once the service has been created it can be utilized within ArcGIS Desktop by attaching to the service. How to connect to basemaps can be found in other modules. Figure 8: Manage Services Introduction to ArcGIS Server Page 7

8 To edit the service double click on the service. These are the same steps you would have used if you had used Add New Service. Add New Service does basically the same function as Publish GIS Resources. Figure 9: Editing a Service The Capabilities Tab gives control over the different types of services which you have created, while you cannot control the Mapping Service, you can control other services most importantly Figure 10: Capabilities the KML service. Introduction to ArcGIS Server Page 8

9 Once you have completed your edits you will select Save and Restart. Anytime you make an edit to a service you must restart the service for it to show the changes made. Creating a Service in ArcGIS Desktop Once you have created your project like discussed in Creating a Project, you can create the service from within ArcGIS Desktop directly. Note: you would use either this method to create a service or from the service manager, you do not do both for a single service. The service can still be edited in the Service Manager as discussed previously. You must create a connection between the server and ArcCatalog before you can publish the service. This is done in ArcCatalog by adding the ArcGIS Server. Within ArcGIS Desktop go to the Customize heading and select Toolbars and select the Map Service Publishing, which will open up a five icon toolbar. You can dock this toolbar or leave it floating. Working from left to right on the icons in Figure 11: Map Service Publisher, the first one will analysis your map and let you know if Figure 11: Map Service Publisher there are any errors. If you have high level errors the map will not publish. The second icon allows you to see a preview map. The third icon allows you to save the map as a MSD (Map Service Definition), you need to have the file in the MXD format to do live editing (to be discussed with SQL Databases). The fourth icon is the one used to publish the map as a service. The final icon gives you a couple options on how text will be displayed. Press the publish map as a service icon. Which will open Figure 12: Publish to ArcGIS Server Wizard. You must name the service with a unique name. I use the default saving location. Remember you are using ArcMap on the server, click next to continue. Figure 12: Publish to ArcGIS Server Wizard Introduction to ArcGIS Server Page 9

10 Figure 14: Type of Services show saving location and then click Finish to create the map service. If there are any errors that are at the high level they will stop the service from being created and you will need to correct these and try creating the service again. If you make a change to the map you will need to recreate the service, this can be done by opening the wizard again and click finish, it will make you confirm that you want to save it with the same name. Once the service has been created go to the Service Manager and the services should appear with the name which you provided. The service Figure 13: Map Service In Figure 14: Type of Services you will select the type of service much like you did in the Service Manager. Note a feature class service must be associated with an MXD file not a MSD file as created in ArcMap. The mapping check box cannot be changed, again also select KML. Click next to continue. The next windows will that was created is called Test2. ArcGIS Server Web The next process will be to create a web map from a service from within ArcGIS Server; this process is under the application menu. All Web Applications which have been created will be Figure 15: Applications Introduction to ArcGIS Server Page 10

11 displayed in Figure 15: Applications and at the top of the window is an icon to Create Web Application. Click on this icon to begin the web application creation wizard. Figure 16: Creating a Web Application Select a unique name for the application and create a description. The name created will be a public name so make sure it is appropriate and descriptive. The Advanced options are also being displayed. Click next to proceed to the next window of the wizard. Note all the parameters in the wizard can also be changed in the editing process of the created web application. Introduction to ArcGIS Server Page 11

12 Figure 17: Layers to Display In this window you will select the services you wish to display and the order of the service as well as the home zoom parameters. First select add layer, the layer must be a service, and will only show the services running on the ArcGIS Server. Select the layer which was created from the above exercise, there might be other services on your server and you will also have access to other online services, both internal and external. If you bring in multiple services than you will need to order them, you can bring in a service and leave it turned off also. Once the services are loaded you may want to customize the initial zoom extent and also the zoom when full extent is selected from the web map. Click on the layer name will also show the properties of the layer. Initially we will use the default values, since these can be modified in the editor after the application is created, click next to continue. Introduction to ArcGIS Server Page 12

13 The available tasks are those features you can configure to be used in the web map. We will only configure the search attribute for this example. Once the Search Attribute has been selected, click on the configure button to open the configuration wizard. The configuration wizard has three tabs. The General tab is for naming the Task Figure 18: Tasks The Setting tab will allow you to select the attributes that will be searchable. For this case we have selected to search only for county names. Note the screen settings in Figure 20: Search Fields. Figure 19: Search Attributes Figure 20: Search Fields Introduction to ArcGIS Server Page 13

14 On the result Tabs you can select how the search will be displayed and what elements will be visible to the user. Figure 21: Results Figure 22: Map Elements Introduction to ArcGIS Server Page 14

15 Once the Task has been configured select next to move to the Map Elements. Each of these elements can be independently configured. Explore the configuration of each of these elements and turn off those that you do not wish to use on your web map. Figure 23: Page Property The final window that we will work with in this module will be the Page Property. In this window you can control the title displayed, the color of the map theme (including creating your own theme) and hyperlinks that will be displayed. The Application Settings tab contains a username and password, if this username has a password that changes, then the web map will stop working when you change your password and you will manually need to fix this problem. Once the configuration of all these properties is completed, click on Finish and a web map will be displayed that can be viewed using a web browser. To edit the map click on the pencil icon in the application window and each of the parameters configured in the wizard be modified. Figure 24: Map Editing Introduction to ArcGIS Server Page 15

16 An API is a Application Programming Interface 1 which can be used to construct web applications that can be used in multiple settings. The ArcGIS Server API can be used in many different programs to display the service. Therefore the service can be displayed in multiple applications such as placing your data on top of a Google Map. API with Google Maps Figure 25: Google Map with Service You can do this function using either notepad or a web editor such as Dreamweaver. In this example code will be shown which was used to create a map (note only a part of the map is visible). Those parts of the code that require editing will be discussed in this application. You will need to have access to a webserver (IIS is required for ArcGIS Server) to create the code as a web page so that it can be accessed. The webserver will need to be on a machine with a public URL.

18 While the listing above is the required code to put a simple map data from an ArcGIS Server onto a Google map, parts of the code must be customized, those parts have been broken out and will be discussed in more detail. Calling Google Map Key <script src=" 8xRoQMxjMPEJQ4W1yN-FYKwF5eu6KRSIzCAjBjF6IgPtd-RqayTcAzyKsA" type="text/javascript"></script> You will need to get a Google Map Key which is highlighted, this is a simple and free process. Calling Your Esri Sercice <script src=" type="text/javascript" ></script> Loading features of Google Map gmap = new GMap2(document.getElementById("gmap")); var centerat = new GLatLng(37, -96); gmap.addcontrol(new GLargeMapControl()); gmap.addcontrol(new GMapTypeControl()); gmap.setcenter(centerat, 5); GLatLng is the Center of the map, the values presented is near the center of the United States. SetCenter states use the GLatLng as the center of the map and the number refers to the zoom level. Location of Your Map var dynamicmap = new esri.arcgis.gmaps.dynamicmapservicelayer (" null, 1, dynmapcallback); The http statement gives the location of your ArcGIS Server services of your map (note this location is for this example your location will be different). The 1 refers to the transparency of the map with 1 being opaque and 0 being invisible. Size of Map <div id="gmap" style="width: 1300px; height:900px;"> This code refers to the width and height of the map. API with Flex and Silverlight Adobe Flex uses the API service will be discussed in detail in a future module. Introduction to ArcGIS Server Page 18

19 Using a SQL Express Database Figure 26: SQL Express To be able to edit online you must use a dynamic database server. There are many different database servers you can use and if you were in a production environment you might use something like Microsoft SQL. For this exercise we will use the SQL Express Database since it available with the Desktop software at no additional cost. Start ArcCatalog and go to the section to add a Database Server. Add the appropriate location for the SQL Express server. It is assumed that the SQLExpress Server has been installed prior to this excerise and properly configured. Once the Database Server has been added in ArcCatalog, you will need to right click on the SQL Server to create a new Figure 27: Add Database Server geodatabase. Once the geodatabase has been created it is empty and you will need to right click on the geodatabase and select import to add data to the SQL Express server using ArcCatalog. After selecting import you will have several choices of the type of information you can add. For this example a single feature was selected. You must tell it the location of the feature to be added and provide an output name (without spaces), see Figure 28: Adding a Feature to SQL geodatabase. Introduction to ArcGIS Server Page 19

20 Figure 28: Adding a Feature to SQL geodatabase Next open ArcMap and begin with a blank template. Add data from the Database Server (SQL Express) Once the layers have been added and the symbology adjusted you need to save the MXD file. Then open ArcGIS Server Manager, go to the Service part and select Publish Service, it cannot be published from ArcGIS Desktop, since it will be a feature class. Create the Service as before using the MXD, include in your creation a feature service and save; you must have pooling set to not pooled. Then go to the application part create all parts as before except in the Task section add the Editor and it must be configured appropriately. Then finish the web service. If all component parts are effectively communicating then you will be able to edit the map in a web browser and also you can edit the service in ArcGIS Desktop. Introduction to ArcGIS Server Page 20
