First, Wenge will outline the challenges and methods involved with maintaining and coordinating STARMap.
Here are a few facts about the regional map called STARMap. STARMap stands for Southeast Texas Addressing and Referencing Map; it was developed by H-GAC GDC in 1999. The purpose of the STARMap is to meet the GDC needs, also address the statewide 911 standards and have a common standard format for the region. It covers 13-County region in the southeast Texas.
This slide shows the sources we use to update STARMap. The partner counties in blue contribute their data to STARMap. H-GAC 911 counties in red exchange the data with H-GAC. The striped layer on the top displays CenterPoint Services Area. We use the centerpoint address point layer and street center lines layer as references to edit STARMap. Aerial photos are another source for editing STARMap. Wealign street segments with Aerial photo to make sure the streets are geographically/spatially correct. User feedback is another good source for updating the STARMap.
Through time, we use different methods to share the data with others. In the past we used CDs to distribute the STARMap. We still offer CDs to those who want to have CD. Now we are using the FTP site to distribute the data . The FTP site distribution method is more efficient than CD distribution method. Inthe near future GDB Replication will be used to share data between H-GAC and 911 counties and web map service will be used to distribute the data to STARMap users. Becky will talk about 911 data and GDB replication.
The same framework that your organization uses to share and edit data can be used to push that data out to the global GIS community.Web map services created by ArcGIS Server eliminate the need to transfer data the old-fashioned way: on CDs, drives, or FTP. (click)After you’ve published all these services, you may want them to be searchable by the global GIS community. One of the best methods for doing this is through a GIS portal, which is an XML catalog that usually has an integrated map application. You can contribute links to your services to an existing portal, such as geodata.gov, or implement your own GIS portal, which H-GAC hopes to do sometime in 2009. (click)
The ultimate goal, especially for a government entity, is to share GIS with everyone, including non-GIS users. The trend is to pass knowledge and solutions directly to the end user, especially over the internet. Web applications, Google mashups, KML, Virtual Earth mashups, and Flex Flash applications are making this task easier for the GIS administratorSuccessful GIS applications are:Easy to use – the public doesn’t want to have to intentionally learn new methods.Familiar – identical or similar to something they would use anyway – like Google Maps.Simple – it is hard to resist the urge to include all of the bells and whistles, but end users are more likely to use the most simple and clean applications.

What is Cloud Computing?• Cloud computing – Internet-based computing – Resources, software, and or information is shared over arrays of hardware.• At H-GAC, we utilize the ArcGIS Online cloud to: – Distribute and update the regional GIS datasets. – Share GIS data with the GIS community and the general public. Texas GIS Forum 2012
ArcGIS Online Cloud Facts• Access free, high-quality and ready- to-use base maps for your GIS projects.• Create and join groups to contribute your content and collaborate on specific projects.• Develop Web applications quickly with ArcGIS Web Mapping APIs and ready-to-use ArcGIS Online content.• Save time and money - no need to invest in additional infrastructure or staffing. ArcGIS Online is hosted by esri and powered by ArcGIS Server and ArcGIS Data Appliance and new content is added and updated continually. Texas GIS Forum 2012

Share with the GIS Community•The GIS cloud services, provided byesri, are a nearly perfect vehicle forsharing your GIS data directly withthe rest of the geographic community– No more emailing, zip files, harddrives, or DVDs. How can the GIS community find your services? •Upload or Share Data – Upload layer packages or share ArcGIS Server services. •Share your services or layer packages with groups or globally. •Create your own group and invite users.

ArcGIS Online for Non-GIS Users My Map (ArcGIS Online): •Easy to use: The public doesn’t want to have to intentionally learn new methods. •Familiar: Identical or similar to something they would use anyway – like Google Maps. •Simple: It is hard to resist the urge to include all of the bells and whistles, but end users are more likely to use the most simple and clean applications.

Summary• As time progresses watch for the following cloud computing trends. • More accurate and up-to-date layers being held in the cloud • The ability to allow editing of GIS data while in the cloud • More cloud computing connections to other social media like LinkedIn and FaceBook• One of H-GAC’s GIS missions is to provide GIS data to public and private entities making for a higher quality of life for the region. One tool that will be utilized at present and on into the future is cloud-based GIS computing. Texas GIS Forum 2012
