GISc
Version 2

Version 2 Web site

Implementation Objectives:

    Provide the user with the ability to enter a search address (Address Finder) and proximity query to return the nearest points of interest (in this case, Registered Sex Offenders located within the NCTCOG member footprint) and use a Map Image Service to display the map.

System specification:

  • Computer hardware used, Dual 400 MHz Pentium 2 CPU, 512 MB RAM, Dual 18 GB SCSI 2 HS/HD, NAS 80 GB (On-site Backup), CI Host Web site hosting service (Web server & Off-site Backup).
     
  • Software applications include, Windows XP Pro, ESRI ArcGIS/ArcView 8.2, ArcWeb for Developers, Microsoft Visual Studio .NET 2003, Internet Explorer 6 Web browser, Access database, CuteFTP Pro ftp data transfer.
     
  • Services required: ArcWeb for Developers, ArcWeb Service Subscription & Web Hosting Service.

Application development:

  • ArcWeb for Developers provides a suite of SOAP-based ArcWeb Services that can be integrated easily into any Web or desktop application.

    With ArcWeb for Developers you can include GIS content and capabilities in your applications without hosting the data or developing any GIS applications yourself, resulting in significant savings of development time, expense, and computer resources.

    A Web Service Description Language (WSDL) describes an ArcWeb Service so a client knows what the service does. WSDLs define such things as available methods, parameters, and parameter types. If you are using a toolkit (Microsoft Visual Studio .NET 2003), you can point it to the ArcWeb Service WSDL to communicate with that service.

  • Database design and manipulation:
     
    • Points of Interest (POI) Manager Web Service to upload Sex Offender Registration addresses to an ESRI system as a DBF file (5,000 record limit per file) and store in a table through a Web-interface.
       
    • Geocode SOR addresses to determine locations and send geocode report back to me. Add, edit, or delete locations in the table through SOAP or Web-interface.
       
    • Upload personal icons to be used on maps.
       
  • Spatial analysis:objectives
    • Address Finder Web Service to provide "find an address" and "get address" functionality.
       
    • Proximity Web Service to find nearest SOR’s within a user-specified search radius.
       
  • Cartographic production:
     
    • Map Image Web Service to define a geographic extent and several optional items (e.g., themes, type of map, size of image, map annotation) and receive the location of an output image file that the user will view (final product).

Issues:

    Integration with my Web site on local host server, Web Service interaction, Points of Interest implementation and user demands.

Web site contains over 100 pages of custom maps and geocoded data created for my use as a UTDallas/GISc student.

Objectives: This project is to obtain public data on the location of registered sex offenders located in and around the Dallas/Fort Worth Metroplex and create maps that illustrate the proximity of registered sex offenders to local schools using the buffer capabilities of GIS software.

Content provided by Texas Department of Public Safety (DPS) Sex Offender Registration (SOR) Database, Texas Education Agency (TEA) Database for school locations and DFWinfo.com Data Clearinghouse for base shapefiles.
