9 So What's the Use? Richland County IT/GIS Governance Model

10 Why Use GIS? Because Everything You Manage is Somewhere: Addresses Roads Zoning Zip Codes Census Tracts Work Orders Permits Rivers & Lakes Voting Precincts Shopping Centers Criminal Activity Water Service Areas Solid Waste Routing Infrastructure - Water - Sewer - Stormwater - Electrical - Telecom Subdivisions Buildings Parcel Mapping Businesses Flood Zones Disasters Emergency Services... and somehow connected.

48 Evolving RCGeo From Consumer to Consumed

49 Geoweb Traditional web is dominated by documents. Geoweb implies merging abstract content with location. What is here? Geoweb provides an open, global and scalable infrastructure for organizing and discovering geographic knowledge => Geodata GIS functionalities such as Geocoding, Geoprocessing to be accessible over the web using standard protocols => Geoservices Developing the infrastructure to handle future geodata, especially ill User generated tdcontent t(news, Photos, Mobile devices) as well as County assets (AVL, sensors) Service oriented architecture Development is cheaper / faster => better tools

50 Quick GIS 101 For software developers

51 Spatial Data Representation in GIS

52 Map Projections and Coordinate Systems The original map showing 10,000 and 15,000 km buffers around North Korea

53 Map Projections and Coordinate Systems The corrected map showing 10,000 and 15,000 km buffers around North Korea

54 Map Projections and Coordinate Systems Common ones are WGS84, Web Mercator, StatePlane. Projection Information is standardized using WKT or WKID (or SRID) representation

55 Spatial Data Types: Shape

56 Feature Class: Shape + Attributes Homogeneous collections of common features, each having the same spatial representation, such as points, lines, or polygons, and a common set of attributes Median Home Value (2008) by Census Tract

57 Feature Dataset A feature dataset is a collection of related feature classes that share a common coordinate system. Feature datasets are used to spatially or thematically integrate related feature classes. Their primary purpose is for organizing related feature classes into a common dataset for building a topology, a network dataset, a terrain dataset, or a geometric network.

58 Raster Data

59 GIS Data Models

60 Geodatabase Container for spatial data. Helps maintain integrity of spatial data, users can apply sophisticated business rules and relationships to data. Enterprise Geodatabase Supports concurrent, multi user editing. File System or RDBMS

61 Do not need GIS software necessarily for storing and processing Spatial Data. PostGRES, SQL, Oracle, MySQL all have spatial data, Q,, y Q p types now and support spatial operations within the DBMS itself

62 Working With Spatial Data

63 Spatial Operations: Buffering

64 Spatial Operations: Difference

65 Spatial Operations: Intersection

66 Spatial Operations: Union

67 Spatial Relationships: Contains

68 Spatial Relationships: Equals

69 Spatial Relationships: Touches

70 Spatial Joins and Relates Spatial joins are the bread-and-butter of spatial databases They allow Spatial joins are the bread-and-butter of spatial databases. They allow you to combine information from different tables by using spatial relationships as the join key

71 Geocoding: forward & reverse

72 Publishing GIS Services: ArcGIS Server

73 Publishing Map/Geo. Services

74 Network Deployment

75 GIS as SOA SOA: Focus on building loosely coupled services (encapsulating business processes) that are shared between applications as opposed to rigid applications SOA Infrastructure : Consumers communicate with SOA infrastructure through DCOM, SOAP Webservices are the preferred implementation method for SOA Both SOAP and REST based

76

77 Map Services Web service that lets you retrieve maps and related data Supports operations such as Query and Find SOAP & REST Dynamic and Cached Also retrieve Symbology, Legend, Metadata etc.. Most of the time you will be working with Map Services

78

79 Geocoding Service Find Address Candidates and Reverse Geocode operations are supported over REST and SOAP

80 Geocoding Service dates? Street=5605+Bush+River+Rd&outFields=&f=pjson "candidates" : [ { "address" : "1249 BUSH RIVER RD", "location" :{"x" : , "y" : }, "score" : 38, "attributes" : { }} }, { "address" : "1155 BUSH RIVER RD", "location" : { "x" : , "y" : }, "score" : 38, "attributes" : { } }, ]

81 Geometry Services

82 Network Analyst Services

83 Geoprocessing Service ArcToolbox + Model Builder in the ArcMap environment Custom.NET, JAVA or Python Code can also be written Geoprocessing operations can be published as web services over www

84 How service requests are executed on ArcGIS Server Server Object Extensions: Extension to ArcSOC.exe

85 Consuming GIS Services

86 Pre ArcGIS 9.3: Client APIs or ADF? Cross Platform was not a big issue. ADF was ASP.NET + Microsoft AJAX (or the Java equivalents) Client APIs for RIA How do you want to allocate processing, Client(API) or Server Side(ADF) What programming language(s) are staff familiar with: ASP.NET == ADF, JavaScript, Flex, SilverLight However, ADF IS DEPRECATED AT 10.1

87 RCGeo IMS 2.0 = ADF (ASP.NET)

88 ArcGIS 10+ Application Architectures 10.1

89 SOA: SOAP or REST? SOAP API is XML based, services are defined through a WSDL, communication can be protocols other than HTTP, Stateful REST API is JSON based defines all resources through URI s every thing is accessed via GET,PUT, POST, DELETE. Stateless when possible Exposing Data / Resources Use REST (Caching, among other advantages) Exposing Logic / Operations Use SOAP (Stateful)

91 Mobile Development Options Native Platform o o o o o o ArcGIS Runtime SDK for Windows Mobile ArcGIS Runtime SDK for ios ArcGIS Runtime SDK for Windows Phone ArcGIS Runtime SDK for Android ArcGIS API for FLEX ArcPad Studio Web App o ArcGIS API for Javascript

92 Performance o Web vs Native Native platforms are optimized i to the hardware Functionality o o Full access to device capabilities Push notifications Usability o UX performance much better Development Costs!

93 RCGEO Web App Development: New Requirements Applications cannot just work on the Desktop anymore Resources are limited, so Native apps for mobile development is definitely NO Single code base for PC as well as Mobile platforms Cross Browser and Cross platform requirements Mobile networks are high latency

94 RCGEO Web App Development Moved from.net ADF to ESRI JSAPI +.NET WCF AJAX Additional Javascript UI frameworks and libraries jquery, jquery UI dojotoolkit (ESRI JSAPI is built on top of dojo) kendoui knockoutjs (MVVM for Javascript) modular Javascript with Dojo require experimenting with Typescript: C# like Javascript from MS! Javascript is as important as VB.NET or C# for GIS Web development Google Maps API, OpenLayers all have JSAPIs == Mashups are Google Maps API, OpenLayers all have JSAPIs Mashups are easy!

95 Focussed Apps: One autocomplete style input

96 Focussed Apps: Clean single page output t ~44 pieces of GeoInformation

97 RCWinds: Mashup ArcGIS server and Google Data using JSAPI s

98 ESRI JSAPI Hello World <!DOCTYPE html> <!--- HTML5 DOCTYPE <html> <head> <title>create a Map</title> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <meta http-equiv="x-ua-compatible" content="ie=7,ie=9"> <link href=" <link href=" <script src=" <script> dojo.require("esri.map"); function init(){ map = new esri.map("mapdiv", {center: [ , ], zoom: 3, basemap: "streets"}); } dojo.ready(init); </script> </head> <body class="claro"> <div id="mapdiv"></div> </body> </html>

99 ESRI JavaScript API

100 ESRI JavaScript API: Essentials - Add basemaps using esri.map.arcgistiledmapservicelayer - Add dynamic mapservices using esri.map.arcgisdynamicmapservicelayer - Create tasks (with deferred callbacks) - esri.tasks.identifytask - esri.tasks.findaddresstask - esri.tasks.querytask -Geometry tasks such as buffering a one mile circle when user clicks on map, reproject GPS coordinates to map coordinates using - esri.tasks.geometry -Await user interaction -Draw results using - esri.layer.graphicslayer - ersi.layer.featurelayer It s a brave new ASYNC world -Symbology using esri.symbol

101 Responsive Web Design RWD is the concept of developing a website in a way that allows the layout to adjust according to the user s screen resolution (view i port) using media queries

102 Media Queries (css) In your screen and (min-width: 480px) {.content { float: left; }.social_icons { display: none } // and so on... } On the header of your website:<link rel="stylesheet" href="this.css" media="(min-width: 960px)">
